Introduction This document must be read by personnel in charge before the assembly and the initial operation as well as before maintenance works. Provided that the complete instruction manual in not available, the manufacturer shall be contacted. If required, the operating company shall translate the instruction manual to user’s language. A safe operation and and a long fatigue life can be only ensured with a proper use of the crane. This instruction manual is intented for the use of slewing jib cranes with booms which can only be slewed manually. A hoisting gear can be assembled on a crane boom solidly or with a carriage, which does not exceed, according to data sheet, the maximum permissible values for load bearing capacity, dead weight, as well as lifting and cross travel speed and has a rated capacity limiter. For reasons of steadiness, the crane can not lift from the floor, according to data sheet, more than 1.4 times the lifting capacity of the crane. During the operation, the maximum permissible lifting load is limited to the nominal load, according to the marked load bearing capacity. Higher loads are forbidden. In the European Union, the legislators demand from the operators that instruction manuals shall be always available and must be communicated to all users. In the Federal Republic of Germany it is necessary to attach additionally a summary of the Accidents Prevention Regulations BGV D6 with the essential security advices in a good visible manner directly on the work station of the crane operator. Operators of crane units as well as the maintenance personnel must have knowledge of the regulations and rules applying for this. Those are in the Federal Republic of Germany in particular: - Accidents Prevention Regulations Cranes BGV D6 - Accidents Prevention Regulations Winches, Hoist and Traction Machines BGV D8 - BGR 500 – Load suspension device at hoisting gear operation
Part A – Operating instructions 1. Information on intended use - The operator shall catch up on the intended use of the crane before start up. Improper use is forbidden. - The crane may be only started up, when the assembly and the equipments comply with the valid regulations. (Declaration of Conformity is available, CE- mark is attached, acceptance inspection or regular inspection is visible on the test seal and still valid) - The crane must be only assembled in an appropriate working environment. An accident-proof operation must be ensured. - The assembly must be executed perpendiculary on a floor which is permanently capable of bearing, plane, vibration- and oscilliation-free. - In the Federal Republic of Germany, only persons who meet the requirements according to UVV (accident prevention regulations) BGV D6 §29 can be appointed as crane operators. - The application and the use of the crane are permitted according to classification in hoisting class and loading group according DIN 15018 (see information in test book). - The slewing jib crane is intended to lift and drive (in each case power-operated or manually) loads on the boom using a hoisting gear. The slewing of the boom may be only executed manually, whereby the load must be guided by another person. - Only hoisting gears which have a dead weight that does not exceed the limiting value, according to dimensions table [Annex A], may be used on the lifting arm to lift and drive loads.* - The maximum permissible lifting speed of hoisting gears on the crane is 8.0 m/min. * - The maximum permissible driving speed of power-operated trolley gears is 20.0 m/min* - Only hoisting gears with an effective rated capacity limiter (e.g. safety clutch) may be used. - The slewing jib crane is designed for a temperature range between –10°C and +40°C. - Only slewing jib cranes with additional mark “F” in their type designation are designed for an outside operation and can be operated till wind force 4, provided that the operating instructions are observed. - Only slewing jib cranes with the additional mark “ex” in their type designation are designed for the operation in potentially explosive areas and can be used in the respective area according to their marking on the device and in the test book. - Under operating conditions above the corrosion-protection class C2 or in the environment of aggressive mediums, special models are required. *) If higher values are permitted, thanks to special designs, they are recorded by the manufacturer in the additional data sheet. The additional data sheet is a component of the test book. - A1 -
2. Usage limits The use of slewing cranes is limited by the number of load alternations (frequency), the load spectrum (load distribution) as well as by the design (execution) of the crane. The use of the crane outside of the intended range can result in dangers to and damages on the crane. Characteristic usage limits are: - Higher dynamic load: Use of hoisting gears and load suspension devices, which require a higher classification into loading group and hoisting class, according to DIN 15018, as designated in the test book of the crane, e.g. during grab or magnet operation. - Tendency to fractures of brittle materials, e.g. glass panels The boom bounces because of the elastic deflection. A gentle set-down is, according to the self-supporting length (column + boom), only possible to a limited extend. - Operation at temperatures under -10°C and over +40°C - Use under extreme ambience conditions, e.g. smelting furnances, acid baths and areas with strong vibrations. - Actions which influence the static of the crane and its stability, e.g. extensions or shortenings of the boom or the column, modifications of attachments, modification of the load bearing capacity, subsequent installation of a hoisting gear, bigger or heavyer as intended or unapproved welding works. 3. Warning of improper use The following use of the crane is forbidden. A nonobservance can result in risks for the operator and its environment as well as damages on the crane structure. a. The use of a crane which is assembled improperly or an equipped crane without manufacturer’s certifications (Declaration of Conformity, CE mark) or test badge. b. The use of a crane which is clearly damaged or defective, maybe also ignoring the blocking and prohibition signs. c.

5. Operation of the crane / operation modes / intervention processes of the operating person Basis for the operation of the crane are the operating manuals for crane and hoisting gear as well as the UVV cranes (BGV D6). These documents shall be displayed on place by the operating company of the machine. These instructions, advices and directives shall be observed. 5.1 Control elements 5.1.1 Power supply switch The power supply switch (drawing 3) is located on the crane column. Normally, it is attached into the column tube, so that only the lockable operation device is accessable for the operator. It has 2 settings: - “0“ the contacts are opened, the crane is currentless - “1“ power supply on crane available The power supply switch cuts the crane from the power supply (all phases). In “0“ position it is possible to secure the turn knob by hinging a padlock. 5.1.4 Control switch Drawing 3 The hoisting gear is operated via the control switch (drawing 4). Normally, the control switch is located on the hoisting gear and connected with it via the control line. The control line serves for the signal transmission from the control switch to the control system of the crane and has a strain relief which avoids a tearing due to the dead weight. The control switch must NOT be used to slew the boom. At the trim line “ideal controlling” the control switch is not attached on the hoisting gear but is located on a control trailer, which is movable in a separate sliding rail on the boom, independently of the hoisting gear. The control switch is equipped with operation elements to control the crane movements as well as with a crane switch (EMERGENCY Stop). For further function descriptions see operating manual of the hoisting gear. Drawing 4 5.1.4 Crane switch / EMERGENCY Stop The red marked crane switch (EMERGENCY Stop) (Drawing 5) stops with operation (pushing) all power-driven functions. By a short clockwise turning the red switch goes back to its starting position and all functions are operational again. Drawing 5 - A5 -
Never operate the EMERGENCY Stop together with other operation element – this could result in movements of the crane. 5.1.4 Locking device of the boom (special equipment, serial at operation in oper-air ground) The locking device of the boom (drawing 6) serves for the secure fixing of the boom in one or more fixed positions of the slewing range. At cranes which are designed for the use on open-air ground, the locking device of the boom serves for the wind bracing on one boom position minimum. The operation (Loosening / Locking) is allowed till approx. wind force 4. Beyond that, very high operating forces occur and the drifting boom is potential danger. For this reason, only loose the locking device if there is no danger of drifting booms due to wind. The operation takes place by pulling the operating rod (A1) till the return stop (A2) below the bearing plate is visible and the locking bolt (A3) releases the boom (1). Now the run-back of the locking pin (A3) is avoided by a 90 degree turning of the operating rod (A1). The boom can slew freely. If the boom shall be locked, it shall be slewed manually to a locking position till the locking bolt (A3) is located under a drilling / locking strap (A5). The locking of the bolt takes place in reverse order. Abb. 6 Drawing 6 - A6 -
5.2 Operational elements All stops are designed as EMERGENCY end stop and must not be arrived during normal operation. (see also BGV D6 § 30). 5.2.1 Stops for limitation of cross travel motions The pictured stops of cross travels are exemplary and can differ according to hoisting gear make. Drawing 7 5.2.2 Slewing brake for adjustment of the stiffness Drawing 8 As special equipment, the slewing brake (drawing 8) serves for the adjustment of the stiffness of the boom (see mounting instructions paragraph 15.3). Slewing brakes are intended for cranes in closed halls. - A7 -
5.2.3 Stops for limitation of slewing According to installation size, crane equipments and intended use, they are a component of the crane construction or the special equipment (take information from the order documents or the additional data list in the test book of the crane). Stops for limitation of slewing shall be employed to: - avoid a crash of the crane boom or of pieces of the equipment assembled on the boom (hoisting gear, power supply etc.) on the interference contours in the environment of the crane (e.g. walls, supports, other cranes) - limit the working area or the boom - safe attachment parts against crashes on the crane column Depending on the function 2 types of stops for limitation of slewing are differentiated: a) Stop for limitation of slewing with buffer rod for clamping on the boom (counter stops in the environment of the crane) Drawing 9 b) Stop for limitation of slewing for assembling on the crane basis (counter stop is the crane itself) Drawing 10 All stops are designed as EMERGENCY end stop and must not be arrived during normal operation. (see also BGV D6 § 30). - A8 -
6. Commissioning - the statutory acceptance tests (according to UVV BGV D6 § 25) must have taken place before the initial operation - the crane must be evidently in a safe and functional condition - the operator must have read and understood the operating manual Steps before commissioning - visual inspection that all parts are free of external damages and reliably operating - activate the power supply switch on the crane column - unlock the EMERGENCY Stop button on the control panel - loosen the locking (if existing on the crane) - use boom and hoisting gear Transport of loads - Select adequate slinging means for the choosen load and the transport. - Hinge the load hook and the boom above the load centre into the load or the slinging mean and tighten the load cable carefully. - Always lifting the load from the floor in fine motion. Use a faster lifting speed for the lifting to the desired height not before the load is hanging safely. - At manually operated cranes, all moves shall be realised by guiding the load or the load cable. The crane operator must drive manually and partially power operated cranes so, that he is able to stop the released travels and rotations without any danger. EMERGENCY Stops (stops) must not be arrived non-braked. - If a direct guiding of the load is impossible, additional guiding aids (e.g. ropes, chains or guiding rods) shall be attached on the load, the load hook or the boom. - Keep the transport process shortly and put the load in a safe position and completely down. Hang the load hook out and bring it to a safe stand-by position. 7. Decommissioning The crane shall be stopped at the end of work or longer stoppages of work as well as in cases of recognized damages or occuring critical situations. - Hoisting gear in standby position - Push power supply switch to 0 condition In cases of interruptions, shutdown or wind force >4, the booms of cranes in operation on open air ground shall be locked by a serial locking in its standby position. - A9 -
7.1 Emergency situation An emergency situation exists, if the crane movement does not stop or is impeded, e.g. by jamming or catching loads. Acting in case of emergency situations - Activate the existing EMERGENCY – STOP devices on the control switch or the power supply switch! - Inform immediately the competent authorities of the company! - Safeguard the danger area! 7.2 Danger to steadiness and security of operation The steadiness is not ensured: - if there are cracks on welding seams of the crane column or the boom, - if there are loosen attachments or screw joints, - if buildings – floor, wall, slab, supports, frames can not absorb the fet forces anymore The security of operation is not ensured: - in case of a high wear of components; breakage, cracks, deformation, corrosion of load bearing components on the crane or in load bearing means (ropes, chains, hooks), - in case of a damage on electrical equipment, - if loads can not be hold (rated capacity limiter and/or brakes faulty or worn) - if there are damaged functional components (stops for limitation of cross travel motion, slewing limitation stops, etc.), - in case of a overload of the crane by exceeding the permissible lifting capacity or e.g. by inching the control switch frequently during the lifting or lowering movement, which results in a higher dynamic pressure. (“inching operation is forbidden!“) 7.3 Closedown A closedown of the crane shall be carried out in case of: - damages or wear till the repair is carried out - achievement of the theoretic remaining service life, - absence of the required maintenance and quality inspections (see inspection plate on crane) After the closedown another use of the crane must be excluded, e.g. by locking the power supply switch in “Off” condition with a padlock. - A10 -
7.4. Disposal After the end of the operation period or irreparable damages on the crane the same must be shut down and disposed as steel scrap. The disassembly shall be only executed by a competent person. Electric components on the crane shall be disposed environmentally friendly. 8. Non permitted use – Ban on operation No Transportation of persons! No Transport of fused materials! No Diagonal pulling, trailing and loose of stucked loads! No Slewing of loads or moving of the crab by pulling the control switch! No Stay in danger area during the crane operation! No Stay under suspended loads!

Security advices The slewing jib crane is designed and constructed according to the state of technology / the valid safety requirements*. It meets the demands of the EC Machinery Directive. Using the crane as intended the dangers to life and limb of the operator and third persons as well as of the material values are low. Thereby a sensible handling with regard to security and dangers according to the operating manual of the crane and the hoisting gear is assumed. The crane must be stopped immediately if defects or irregularities are determined at the function. The safety distances shall be observed obligatory according to the valid directives BGV D6 §11. *) At the date of placing on the market - A11 -
9.1 Responsibility of the operating company - Right selection and load of the crane - Sure function and fixation on crane and loads - Sure operating condition of the crane - Sure operation and use by the operating personnel - Initiate required acceptance tests and recurring inspections You, as operating company, are responsible for the acceptance of the crane and for recurring inspections (maintenance) according to BGV D6 and BGV D8. All persons who are authorised with the operation and maintenance of this crane must have read carefully and understood this operation manual. Any non-compliance and act in opposition can result in accidents and dangers. Additional to the operation manual, the operating company of crane units must also observe and instruct the general laws and provisions for the prevention of accidents and to the environmental protection. The following protection devices exist on the slewing jib crane: 1. Stops for limitation of cross travel motion on boom (emergency stop device) 2. Slewing limitation stop (partial special equipment) 3. Protective conductor of boom and crane column (only cranes with electric equipment) Due to special local conditions or cases of operations, situations could exist or appear, which are not considered in this operating manual. In such cases the required measures for the security of the operator shall be decided and initiated. The operating manual shall be completed by the operating company with instructions regarding work organisation, working processes, authorised personnel, obligations of supervision and to inform etc. 9.2 Working environments The slewing jib cranes are remote-controlled cranes. That results, that the operator must know the working environment, especially with regard to obstacles in working and transport area, possible tripping points and existing control elements and safety devices (e.g. emergency stop switch). Release and swing of loads are forbidden. Manual operated cranes shall be guided on the load hook and/or the load. Safety distances to stacked material must be observed. The guiding of loads on ramps, chambers or towers is dangerous. There is a risk of falling. Here, the operating company arranges additional safety measures. - A12 -
9.3 Choice of personnel and personnels qualification According to UVV BGV D6 § 29 the following directive applies: “To operate and maintain the crane independently the operating company may only authorise persons, - who are physically and mentally suitable - who are likely to fullfill their tasks reliable - who are instructed in driving and maintain the crane and have demonstanted their competence - who have reached 18 years of age. Only adequate qualified personnel may be deployed for repairs and maintenance works. Works on electric equipment may only be executed by an authorised electrician or by instructed personnel and under the direction and supervision of an authorised electrician.” 9.4 Security advices for operating phases 9.4.1 Transport and storage The slewing jib cranes must be transported and stored as demounted components. Hereby the essential components, crane column and boom, are not stable due to their geometry. For this purpose the components are provided ex works with adequate disposable transport aids (pallets, square timbers, stretch tapes). This transport aids shall not be removed before the assembly. During the transport, the packing units shall be secured on the transport mean against slipping and tilting (e.g. load restraint assemblies in case of delivery with truck). In case of a later assembly of the crane the components crane column and boom shall be put for transport and storage on adequate stable transport aids and shall be additionally secured against tilting, rolling and slipping with load restraint assemblies and support blocks. During the storage, the components should be secured against atmospheric influences. The storage should take place between –20°C and +45°C. 9.4.2 Normal operation Emissions Noise emission: At motor driven hoisting gears the noise emissions vary from low up to high noise levels.

By starting the carriage, ensure the function of the cross travel stops after the assembly. CAUTION: Without cross travel stop on the head of the boom, the hoisting gear (with load) moves from the boom Æ danger of fall down of the load!!! - B10 -
15.3 Assembly slewing brake The slew brake (special equipment) serves for the adjustment of the slewing rate of the boom. The brake shoes equipped with a brake pad can be pressed on the slewing column via a manually fine adjustable disc spring packet and as a result they avoid, according to pretension, the overtravel of the boom. 40.3 40.11 40.1 40.10 40.12 40.1 40.3 40.11 40.2 Assembly: Drawing 18 1. Position the both blocks (40.1) with the distance pieces (40.2) downwards on the lower console of the crane column between the guide plates intended for this purpose on the lower console of the crane column. 2. Attach 10 disc springs (40.12) in each case (according to drawing 18) on the screws (40.11) and connect the both blocks using the scews and nuts (40.10). 3. The braking effect is adjusted by tightening the nuts (40.10) uniformly. Is case of the subsequent equipment of cranes with slewing brakes it is necessary to refit guide plates on the lower bearing console. In this case, please observe the separately available assembly instructions. 15.4 Assembly slewing stops The sleving stops serves for the limitation of the slewing motion (special equipment). Slewing stops in weldable design are provided as all-purpose fixed stops on the head of boom. The stops consist in each case of a steel profile as well as of a rubber buffer (41.10) with stay bolts and a flat washer (41.11) and a hexagon nut (41.12) for the fixation. During the welding, the rubber buffers shall be removed from the profile. 41.10, 41.11, 41.12 Drawing 19 - B11 -
Slewing stops with buffer rod are provided for the assembly in the area of the head of boom. For reasons of the optimum load application the stops provided for clamping on the upper flange or the end plate shall be - Assembled max. 300 mm before end of boom - Take effect perpendiculary on a fixed counterplot in the environment of the crane Drawing 20 Please review before assembly: - Do you meet the requirements of welding on cranes? - Allow the environmental conditions on assembly site a welding? - Are all equipments, hoisting gears etc., relevant to define the slewing range, assembled on the crane? - Which interference contours in the environment of the crane shall be protected against impact of the boom and how must the boom protected against impact? - Decide on which point (Crane column or lower bearing plate) and in which position (standing of lying) the universal stop must be welded to fulfil its function. - In this connection, please take account to a maximum long weld seam (GSX design size 1- 3 minimum 75 mm, design size 4+5 minimum 120 mm). Assembly: 1. In the area of the projected welded seam, remove locally the existing anti-corrosion coating. 2. Attach the buffer and check the intended function – if necessary, adjust the position of the buffer. 3. Completely weld the buffer on (hollow weld a=3mm (size 1 to 3) and/or a=4mm (size 4 and 5). 4. Check the function of the stops with and without load on the respective final positions of cross travel. 5. Using the included correction colour, renew the anti-corrosion coating in the area of the welded seam. - B12 -
15.5 Assembly locking of boom The locking of the boom is intended for the fixation of the boom in one or more positions within the swivelling range of the crane. At cranes for outdoor operation the locking is standard equipment and serves for wind bracing (see also chapter 5.1.4) The locking of the boom is pre-assembled ex works on the crane column. During the installation of the crane and assembly of the boom the locking of the boom shall be adjusted in position “loosen” (control rod A1 pulled and locked) to ensure a smooth hanging in of the boom. Check the locking for function after assembly of the boom (see chapter 14) and, if necessary, readjust the slewing bracket. Drawing 21 During maintenance and repair works, it could be necessary to disassemble the locking to replace for example the spiral spring. In this case the bolt (pos. A2 and A6 – called return stop) must be replaced and the control rod can be pulled downwards out of the guide plates. Remove spring and flat washer carefully. Caution – the return spring is under pre-tension. The assembly proceeds in reverse order. Position the new spring (A4) and the new flat washer (A7) between the plates and the control rod into the drilling holes of the guide plates. Lock it with bolt (A2 and A6) and, after assembly, check locking for function. - B13 -
