Gantry Crane for Beam Handling / China leading crane manufacturer

 This gantry crane is for the hoisting or moving of railway/highway concrete beams or bridges. There are 2 kinds gantry crane for beam handling: beam hoisting crane and beam moving machine.

 

Gantry crane for beam hoisting

 

For Beam Hoisting:

Gantry crane for beam hoisting is composed of main beam, supporting legs, crane traveling mechanism, hoisting mechanism, electric control, hydraulic system, cabin, railing, ladder and walkway, etc. And there are 2 types of crane traveling: Tire traveling and rail traveling.

 

The crane traveling, steering and hoisting of tire type gantry crane are all driven by hydraulic, which can realize traveling straight, oblique and horizontal, etc. Features of tire type gantry crane: Strong adaptability, high working efficiency, small footprint, need no rails, etc. Thus it is widely used for high speed railway construction for beam lifting, moving and loading.

 

Rail mounted gantry crane for beam hoisting is usually for lifting railway beams within 1,000t, which is driven by generating units on it. This crane travels on rails with 2 directions: straight and horizontal.

Dam Top Gantry Crane / China Leading Crane Manufacturer

 Dam top gantry crane is employed to lift floodgate, Hydro-generating unit and trash rack on dams. The working area is a line or belt area along its running rails. The structure is plate girder or box girder. The lifting mechanism, gear box which hoist and crane traveling mechanism are driven by motors. There is a closed operation room on main beams. The slings is a hoisting beam powered by flexible cable device. The foot is protected by Buffer device and Windproof rail clipping device.

 

Dam top gantry crane

 

There are two kinds of dam top gantry crane: 1. Single direction: The lifting mechanism (slings/hook) is fixed on trolley and only travel along the rails direction on main beams, thus it can only lift one side floodgate/trash rack. 2. Double directions: The lifting mechanism on trolley can move vertically against the main beam rails direction, thus it can be used to lift 2 sides’ floodgates/trash racks of upstream and downstream.
