Product Description

Brief Introducion:
 
QD type double girder overhead crane is characterized by more reasonable structure and higher strength steel as a whole crane. 
Single girder overhead crane is more typical when lifting capacity less than 20T.

Used together with CD1  model MD1 model electric hoist as a complete set, it is a light duty crane with a capacity 0.5 ton ~ 32ton.
The span is 7.5m~ 22.5m. Working duty is A3~A5, working temperature is -25-40ºC. 
This product is widely used in steel mills, warehouse,hydropower station,production workshop, production line, materials stocks,
equipment assembly etc to lift goods. 

We have comprehensive standard equipment and professional design engineers to offer best solutions for individual requirements.
This product has two operational methods, ground(pendant controller /remote controller) or cabin.

Safety Devices for overhead bridge crane:
 
To guarantee the normal operation of crane and avoid the personal casualty and mechanical damage, the safety device we
provide are not only the electric protective devices or alarm bell but also other
equipments as following:
1.Overload Limit Switch
2. Rubber Buffers
3.Electric Protective Devices
4.Emergency Stop System
5.Voltage Lower Protection Function
6. Current Overload Protection System
7. Rail Anchoring
8.Lifting Height Limit Device

Advantages of a single girder design:
1)Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the
bridge and runway beams.

2)Most economical option for light to medium-duty cranes

3)Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing
roof structure without the use of additional support columns.

4)Better hook approach for both trolley travel and bridge travel

5)Easier to install, service, and maintain

6)Ideal for workshops, warehouses, material yards, and manufacturing and production facilities

7)Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time

8)Great for facilities with low headroom
