Product introduction

Electric hoist double girder overhead crane is one kind of bridge crane with the electric hoist as the lifting mechanism, with the lifting capacity 5 ton to 63 ton, used for general material handling and lifting, widely used in machining workshop, product storage and dispatch warehouse, plastic injection molds changing, finished steel product industries;The working class of the electric hoist overhead is A3 to A4.


Technical Description:

1As one kind of common material handling equipment.

2The electric hoist double girder overhead crane is widely used in machinery processing workshop, warehouses, yard, plants, and other places, etc.

3It also can be used as an alternative for double girder overhead crane.

4Used in production workshop of textile industry and food industry, etc.

5It is forbidden to work in environment with combustible, explosive or corrosive media.

Henan Kosta Machinery Equipment Co., Ltd.


Main features

  • Use imported motor with insulation grade of F and protection degree of IP54. With overheat alarm. The motor is shielded by aluminum alloy stretching cover with good heat dissipation performance.

  • Imported reducer from Germany. hardened gears with good bearing capacity, excellent seal without penetration of grease.

  • Main electric components imported from international brands such as: Siemens, Schneider and ABB etc. with protection degree not lower than IP54.

  • Wheels are forged by 65mn alloy steel with features of wear-proof, anti-fatigue and long service life.

  • Low energy consumption and maintenance free.

  • Whole crane energy saving about 30%.

  • All-in-one transmission mechanism making it work more efficient.

  • Variable frequency control whose high and low rotating speed ratio is 1:10 and work efficiency increases more than 20%.

  • Manufactured by advanced technology and constituted by high quality imported components greatly reducing malfunction and cost.


Our advantages

1Double girder structure makes the crane bridge have sufficient strength, rigidity, and stability.

2Rail-in-middle box girder design thoroughly meets the requirement to strength, rigidity and stability.

3End beams designed with simple structure can be easily installed with main beam by high-strength bolts.

4Soft starting motors with light current is used with ground control.

5Dual-motor independent drive device is adopted to reduce the wear of rail gnawing and reduce the possibility of wheel climb off track fault, etc.

6Multiple safety protection system is adopted, including short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, etc.
