Components of electric hoist double girder cane:

The electric hoist double girder overhead crane is mainly consisted of the following crane components, such as, bridge frame, hoist trolley, crane travelling mechanism, and electrical control system.

Applications:

As one kind of common material handling equipment, the electric hoist double girder overhead crane is widely used in machinery processing workshop, warehouses, yard, plants, and other places, etc. It also can be used as an alternative for double girder overhead crane, used in production workshop of textile industry and food industry, etc.

Advantages of electric hoist double girder crane:

• Compact structure, good rigidity.
• Easy operation, low noise.
• Low building height clearance.
• Light weight and small wheel pressure.
• Safe and reliable.
• Attractive appearance, etc.

Features of electric hoist double girder overhead crane:

• Double girder structure makes the crane bridge have sufficient strength, rigidity, and stability.
• Rail-in-middle box girder design thoroughly meets the requirement to strength, rigidity and stability.
• End beams designed with simple structure can be easily installed with main beam by high-strength bolts.
• CD or MD high quality wire rope electric hoist is used as lifting mechanism.
• Soft starting motors with light current is used with ground control.
• Dual-motor independent drive device is adopted to reduce the wear of rail gnawing and reduce the possibility of wheel climb off track fault, etc.
• Motor is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.
• Frequency converter is used to change the frequency and voltage of motor power to realize the function of speed adjustment control of motor.
• Multiple 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.
