bridge crane hoisting installation package

General overhead crane: including hook  overhead gantry crane , grab crane, magnetic crane, dual overhead cranes, bridge cranes with three. Its hook type spreader, grab, electromagnetic sucker type in one or both of which two, three. General overhead crane is widely used in indoor and outdoor warehouses, factories, docks and open storage yard, etc.,

(A) lifting
     And lifting equipment according to the site conditions, decided to use slice lifting, then again in the rail beam assembly solution. According to gantry crane  lifting height, single girder and trolley assembly weight, the choice with enough tonnage truck crane lifting.
     1. The first conductive side girder beams tied good, in the main beam of sufficient length cable ends faculties, slowly lifting 200-300mm rear brake.
     2 Check the lifting rope is solid.
     3 When double girder crane slowly lifted, with the ends of the main beam control cables lifted from stable, and to ensure that no interference with other nearby buildings. Lifting crane to over conductive side rail height adjustments to the installation location girders,  overhead gantry crane  slowly put down.
     4 In the conductive side of the main beam at the wheel brake with wood, and in the end beam interface pad with a real sleeper.
     5 tying drive side girder lifting, lifting to a certain height in the main beam Xiadian bracket, the driver chamber to move the drive side main beam main beam positioning hereinafter connection.
     6 would drive with cab side girder lifting to a certain height, with a cable to adjust it to the installation location.
     7 bolts to connect the two main beams, as required symmetrical fastening bolt group.
     8 Remove the crane slings and sleepers.
     9 lifting trolley, the trolley bridge crane to track.
(Two) auxiliary equipment installation
     1 lifting maintenance hoists, and make the main beam welding firm.
     2 Install end beam railings, railing trolleys, carts moving side railings, racks and vertical conductive side railings, small transport cable slip line.
     3 car conductive mounting bracket, inclined ladders and platforms.
     4 Install the hook, wire rope rope rope fastening plate.
     5 Installation buffer meet.
     (Three) installation of electrical equipment
     1 in accordance with the electrical master plan, installation of all electrical equipment and components.
     (2) mounted on the control panel to go on stage (box), resistors and other heavy equipment, you should try to make the bracket firmly in taking NTU lap stretch, the resistors should be as close to the control panel (box), the coupling shortest wire.
     3 resistors should be along the direction parallel to the main beam placement, resistors Diego installed does not exceed 4 boxes.
     4 Follow the electrical schematics, put the line will connect all the electrical equipment and components.
     5 wire should go line pipe (trough), line pipe outlet should be added rubber sheath, all the ends of wire numbers on the design drawings shall be well marked for inspection.
     6 cable is mounted on the pulley, the cable hanging under suitable length, uniformity, tackle flexible movement.
     7 Where a crane on the exposed conductive parts accessible due protection.
     8 After checking the wiring is correct, power debugging.

     The above is for your general details of bridge crane hoisting installation package.
