The topic of the crane is too much: The topic of the crane is too much Overhead and Gantry Cranes safe operating procedures   : Overhead and Gantry Cranes safe operating procedures   One , should be carefully checked before driving machinery and equipment, electrical parts and protective safety device is intact and reliable. If the primary attachment controller , brakes, stopper , bells , emergency switches and other failures , is prohibited hoists . Second, members must obey the command signal , but the emergency stop signal given to anyone , should immediately stop. Third, the driver must be able to conduct operations after confirmation command signal , preceded by car -ringing . Fourth, when approaching hoist limit switch, the size of the car near the terminal or meet with the neighboring lane , the speed to slow. Allowed to use instead of reversing brake limiter instead of parking switch, emergency switch instead of an ordinary switch. Fifth, should walk up and down the aisle on security , dedicated site or escalator provisions . Carts on both sides of the track are not allowed to walk outside in addition to maintenance . Forbidden to walk on the trolley tracks. Not allowed to cross from one crane to another crane. Sixth, stop work shall not be lifting objects hanging in the air to stay. Operation, the ground put someone or hanging off the warning bells should sound . Prohibited substance in a person's head hanging cross . Lifting objects from the ground may not be too high. Seven , two crane while lifting an object, to obey the command , in unison . Eight runs, to maintain a certain distance between the crane and the crane . Nine , maintenance crane against a safe place to be , cut off the power , hang " prohibition and gates ," the warning signs . Ground to set up fences and hanging " closed to traffic " sign. Ten, when lifting heavy objects tonnages should first try hanging slightly off the ground , hanging confirm stable braking is good, then rise slowly to run. Allowed simultaneous operation of three control handle . XI, mobile crane 500 ton operation, prohibited people from top to bottom . Also allowed for maintenance and adjustments at runtime. XII running a sudden power failure occurs , the switch handle must be placed "0 " bit. Lifting parts or not put locks are not decoupled , not allowed to leave the cab. XIII runtime failure caused due to sudden decline when hanging pieces must take urgent measures to no place to land. XIV, open-air crane in case the storm , lightning or high winds more than six should stop working, turn off the power , the front and rear wheels should be firmly card game pad . Fifteen , night work should have adequate lighting. Sixteen , gantry cranes in addition to the implementation of these provisions should also pay attention to whether the obstacle when driving on the track ; sides should set up special surveillance and command and tall when lifting objects obstruct the line of sight . Seventeen , the driver must be carefully done "Ten is not hanging ." 1 , does not exceed the rated load hanging ; 2, the command signal is unknown, weight unknown , dim light does not hang ; 3 , slings and accessories tied strong, does not comply with the safety rules are not suspended ; 4 , crane hanging heavy lifting is not processed directly , 5 , pull Xiegua not hanging crooked ; 6 , stand on the workpiece or workpiece floating 30 ton crane stood there live animals are not ; 7 , oxygen bottles, acetylene generators and other explosive items are not hanging ; 8, with notched edges are not really hanging mats ; 9 , the buried object is not suspended ; 10 , liquid or fluid costumes are not hanging too full . Eighteen , work completed, crane should be stopped at a predetermined position , raised hook, trolley tracks open to both ends , and the control handle to place a "0 " bit , cut off the power . 15 items assembled crane operations should be noted : 15 items assembled crane operations should be noted 1 , when lifting heavy objects , hook wire rope should remain vertical , oblique allowed to drag the object to be hung . 2 , the heavy lifting should identify the center of gravity , and tied securely . There are acute application skids pad. 3 , the heavy lifting off the ground is not in front of the jib crane is not doing rotary motion . 4 , when lifting or lowering heavy , steady speed should be uniform to avoid drastic changes in speed , causing heavy in the air, swinging , dangerous. When falling weight , speed, not too fast, so as not to break heavy landing . 5 , crane hoists in the case , try to avoid the ups and downs arm . In the case must hoist arm when landing , from 50% by weight shall not exceed the specified weight. 6 , when the crane lifting heavy rotation in the case , should pay close attention to whether there are obstacles around , if it should try to avoid or remove obstructions . 7 , under the crane boom may not have staff to stay , and try to avoid people through . 8 , two cranes operating on the same track , the distance between the two planes should be more than 3m. 9 , two cranes lifting an object when combined , can not exceed two from the weight of the total from 75% by weight of the two double girder gantry crane walk the line , dipping the action to be consistent . 10 , lifting, luffing rope need to check once a week , and make records , according to the specific requirements of the implementation of the relevant provisions of the lifting rope . 11 , walk the line or turning when empty hook to more than 2m from the ground . 12 , when the wind more than six , should immediately stop work . TMK arm should go off downwind and appropriately low , the hook hanging in prison. Gantry shall lay iron wedge ( only rail ) , and rose to ceiling hook . Meanwhile shut doors and windows , turn off the power , pull good wind cable ropes. Usually after work should also do the same . 13 prohibited the stacking crane platform miscellaneous objects even prevent fall injuries in the operation , frequently used tools should be placed in the operating room dedicated toolbox. 14 , running, allowed a sudden shift or turn the clock back , to avoid heavy swing in the air , are not allowed to operate simultaneously over two items ( including auxiliary hook ) operating mechanism . 15 , while driving , hand operator shall not leave the controller , when a sudden failure of the operation , measures should be taken to a safe landing weight , then cut off the power for repairs. Repair and maintenance in operation is prohibited .
