Single girder overhead crane is a kind of crane travelling along two parallel rails and lifting mechanisms travel along horizontal main girder. Chinese standard single girder overhead crane is composed of main girder, end girders, traveling mechanisms, lifting mechanism (hoist) and electrical components. This crane is usually used in long distance workshops and runs along the rails on both sidewalls.

Design & Application

The LD type electric single-girder bridge crane is designed according to GB3811-2008 and JB/T1306-2008 standards. It is a workshop lifting equipment used in conjunction with electric hoists of types CD1, MD1, and WH164, and is one of the most widely used and economical lifting equipment in factories, warehouses, and workshops. The electric single-girder bridge crane is renowned for its simple structure, economic practicality, and small space occupation. This crane is a single girder type crane with traditional steel girder or box-typed girder. The lifting capacity is usually less than 20 tons. This type crane can be used in steel plants, hydro-power stations, warehouses and workshops etc.

Mechanisms of Chinese Standard Single Girder Overhead Crane

• Rigid box-typed main girder;

• Shot blasting for the whole body after welding and releasing internal stresses;

• Painting epoxy zinc-rich primer, and the thickness of oil film is 140μm;

• Main girder and end carriages are connected by 10.9 degree high-strength bolts;

• Driven by electric reducer or traditional LD drive system;

• Running smoothly, brake efficiently, long service life;

Electric System

• Supplying power through steeples downshop condutor;

• The crane and hoist are mutually independent and could travel at the same time;

• Etch-proof control handle with protection degree of IP54;

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

Safety Protection

Overload limiter, limit switch (lifting and travelling), interlocking protection device, buffer, rail clear plate, shield, bus protection plate, anti-collision device, main disconnecting switch, emergency brake system and motor overload protection device.
