Product introduction

LD Type Single Girder Overhead Crane is the most common type of overhead cranes used for small to moderate lifting applications. It is extensively applied in workshops of manufacturing, repairing and assembly lines, warehouses and storage yards to carry out different lifting tasks. This typical single beam overhead crane cannot be used in flammable, explosive or corrosive environments. This type crane is capable of lifting a large amount of weight, ranging from 1 ton to 20 ton. It is generally equipped with CD or MD electric hoist. According to specific requirements of clients, the LD type single girder crane can also be custom designed and fabricated.


Electric System:

1Power supply through slide lines.

2Phase protection; automatically disconnect main power when phase stagger occurs.

3The crane and hoist are mutually independent and could travel at the same time.

4Sliding contact line meets the requirement of power supplying and adapts shaking.

5Etch-proof control handle with protection degree IP54.

6Heavy-duty aviation plug.

7Electrical components are equipped in position that convenient to maintain, and with good protection to avoid inadvertent contact.

8Electric cable is suspended in cable trolley which slides flexibly and smoothly on a C-type steel.
