40Ton Overhead Crane Double Girder

40Ton Overhead Crane Double Girder

Double girder overhead crane is composed with girder frame, crane travel device, and the trolley with lifting and moving device. There are Pave the rail for the trolley move on the main girder. Assemble the moving table on the outside of the two main girder, one side is prepare for the assemble and maintenance the crane move device, another side is prepare for the assemble of the trolley conductor device.

There are full field of view Cabin suspend under the main girder, there are joint control desk or single control box packed within the Cabin, assemble the sidelong ladder between the Cabin and moving table, The main girder joint with the two side end carriage which with the joint point in the middle.

Attention: Safety is the most important issue for double girder overhead cranes.

1. Safety system:
1). All the cranes are equipped with overload protection device, top quality long time bearing polyurethane materials buffer, Crane traveling limit switch, voltage lower protection function, emergency stop system and so on.
2). All operations are controlled by central control system with excellent after sales service.
3). The whole machines would be guaranteed for one year from the test run date.
4). Low charge for continue maintenance when warranty is expired.
