Customized Single Girder Overhead Crane , 20 Ton Hydraulic Grab Bridge Crane

Hot Sale Customized 20 Ton Hydraulic Grab Bridge Crane With Grab Capacity 20t

Description of single girder overhead crane

Grab bridge crane is widely used for hoisting of common goods in various factories and mines.

Wheel base determination principle

The principles for determining the wheel base of grab bridge crane are as follows:

(a) it can meet the stability requirements of gantry along the crane track direction;

(b) the physical dimensions of the cargo shall be able to pass through the flat steel frame of the supporting legs;

(c) pay attention to make the wheel base B and span S into a certain proportion, generally take wheelbase B= (1/4 -- 1/6) S.

Application:

1. Grab bridge crane is widely used for loading, unloading and transportation of bulk materials in power plants, freight yards, workshops and docks.

2. Grab bridge crane cranes are all heavy duty working system.

3. All the mechanisms of grab bridge crane are operated in the driver's cab, and the directions to enter the platform door of the cab are: end in, side in and top in.

4. The rated lifting weight of grab bridge crane includes the weight of grab.

5. There are two kinds of parallel vertical girder in the opening direction of grab.
