Customized 5 10 15 20 Ton LH Model Electric Hoist Bridge Crane
Electric Hoist Double Girder Overhead Crane Introduction
LH type electric hoist double girder bridge crane: This type of hoist bridge crane has the characteristics of small size, low building headroom, light weight, and low purchase cost. The hook can be raised between the two main girders of the crane to realize Greater lifting height. Generally, the lifting capacity is 3-50t, the span is 10.5-31.5m, the working level is A3, and the working environment temperature is -20℃～40℃. Modes of operation include ground wired handle, ground wireless remote control, cab operation and a combination of both provide excellent ride characteristics, minimizing wear and tear on end beams and crane runways. Every crane and every crane component provides you with high quality, high efficiency and reliability assurance.

Electric Hoist Double Girder Overhead Crane Design Diagram
Features of electric hoist double girder overhead crane
- Double girder structure makes the overhead crane bridge have sufficient strength, rigidity, and stability.
- Rail-in-middle box girder design of the double girder overhead crane thoroughly meets the requirement to strength, rigidity and stability.
- End beams of the double girder overhead crane is designed with simple structure which 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 of the double girder overhead crane.
- Soft starting motors with light current is used on the double girder overhead crane. And also ground control can be used with the double girder overhead crane.
- 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 of the double girder overhead crane is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.
- Frequency converter is used on the double girder overhead crane 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 by the double girder overhead crane, 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.
