Electric travelling rails model gantry crane for yard 5tons
This product is an ideal crane, widely used at open ground and outside warehouse or railway sideways for loading unloading and lifting. It has two controlling methods, namely ground and cabin control.
It is used together with CD or MD model electric hoist, a kind of track travelling small and MID-light type crane. Its proper lifting weight is 3 to20t capacities, span is 12 to 30m; Working temperature is -25 to 40° C centigrade.
It has box type and trussed type two types, box type has characteristic of slim body and strong lifting capacity; Girder type has characteristic of small windward surface, small deadweight and strong lifting capacity.
Design features include:
1. Main girder:
Is welded of steel plates, connected by high-strength precision bolt. There are sliding rail for trolley to travel upper the girder which is fixed on outrigger by high-tension precision bolt
A). Consist of rigid outrigger and flexible outrigger, all connection points are connected by high-tension bolt
B). The ladder is used by operator to enter into cab or arriving at winch
C). When the span>30m, there need a flexible leg aiming at reducing the lateral thrust the trolley has to the rail when the girder load objects.
3. Travelling mechanism
Consist of driving gear box and passive wheel box.
A). The driving gear box supplies power to realize the crane's travelling.
B). What the difference between driving gear box and passive wheel box is that passive wheel box lacks transmission structure such as dynamo, reducer and a pair of exposed gear
4. Trolley with hoist
Is made up of trolley frame, winch and pulley block
A). Trolley frame welded of steel plate is the loading and travelling mechanism of trolley with hoisting
B). Winch is the lifting mechanism of trolley...When it works, wire rope affects the pulley as rising and falling movement, which makes suspended objects lifting and lowering
Warning: Wire ropes need to be examined regularly and changed in time if there is a 10% broken wires, loosen wires and wearing down.
A). Glass window through which one can watch overall working condition is installed in the front and two sides of the cab
B). Electric cabinet as a group of independent cabinet, fixed outside of cab is connected by control cable and linkage station which is set up in the cab
6. Electrical system
A). Lifting motor, crane travelling motor and hydraulic power motor are included. The whole electrical system is controlled by PLC.
B). Two ways to operate the crane: Cab operating and remote controlling.
C). Electric components are imported from Schneider in Germany
Platform is installed in order to maintain the crane, the protective guard is added to protect the safety of servicemen.
