Electric Motor Single Girder Gantry Crane 20ton with Electric Hoist

MDHGgantry crane with electric hoist is a kind of new crane intergrating the advantages of MDG type crane and L type crane ,the characterized :

1.Simple and rational design structure,light weight and low cost.

2.convenient installation , ground beam connects with high strength bolt on the leg, girder is set into the cantilever for the leg ;the electric hoist hangs on the Z-shape steel .

3.Handy operation and rliable performance . The speed can be controlled and the entire operating face can be covered .

in particular suitable for the turning operation of long materials hoisting .in which a trolleytravels along a single girde for reverse rolling horizontally or vertically and safe inverse hook so as to insure the safe and reliability of operation .

The materials of gantry crane

Molding, no welds, high-precision cold-formed molding,

eliminating the traditional production grinding, cutting,

welding, and many other complicated production process, reduce to the

deformation of the single beam crane girder in the handling process,

to ensure that a single beam crane girder precision. Improve the work

efficiency, while greatly enhanced the whole strength, and improve the

quality of cranes appearance.

Suitable situations of gantry crane

It can be widely used in the plants, factories, warehouses, goods yard, workshops environmentsto load orunload goods and improve the working efficiency saving the labor.It is similar to other models gantry crane or overhead crane which has three control methods.

1. pendant control

It signs six positions control, that is , up and down, left and right, front and end , some even up tonine positions to control.

2. remote control

It is similar to the pendeant control, the difference between both is remote control adoptingwireless control, adopting receiving signal.

3. Cab control

In general, Cab control is used in the heavy tons, because it is so expensive. However, it isthe most comforable one in the three.

The driver in the cab controls everything, there are comforable chair and all electric parts.No matter what happens, all working worker must obey the driver's instructions.

Safety features of gantry crane

MDHG model single girder gantry crane with electric hoist many safety features as the safety regulation of the crane equipment:

1. over weight protection device

2. over pressure protection device

3. over current protection device

4. cable line and limit switch

5. corrosion resistance materials polyurethane
