Accord to different work area, single girder gantry crane have different type as follows:

1. Semi- Single girder gantry crane with electric hoist

2. Single girder gantry crane with One cantilever

3. Box type single girder gantry crane without cantilever

4. Box type single girder gantry crane with two cantilever

Main Girder and Support Leg:

There are two type structure for the main girder and leg as follows:

Truss Type VS Box Type

1. Truss type advantage( if work area with heavy wind, choose this type):

a. Small windward side and wind resistance

b. Light dead weight, Low cost

2. Box type advantage:

a. Compact structure, save shipping cost, indoor use available

b. Nice appearance

Safety feature

1.Weight overload protection device:If the lifting material is over the rated capacity, the crane will give a

sharp warning for protection itself.

2.Limit switch: To prevent over hoisting & over lowering of hook

3.Top quality long time bearing polyurethane materials buffer

4.Cabin control or remote control to avoid any injure to the operation staff

5.Voltage lower protection function,

6.Emergency stop system:If the operation staff encounter some emergency situation, we could start the

emergency brake system to protection the related treasure.

7.Current overload protection system
