1. Double girder structure makes the crane bridge have sufficient strength, rigidity, and stability.
2. Rail-in-middle box girder design thoroughly meets the requirement to strength, rigidity and stability.
3. End beams designed with simple structure can be easily installed with main beam by high-strength bolts.
4. CD or MD high quality wire rope electric hoist is used as lifting mechanism.
5. Soft starting motors with light current is used with ground control.
6. 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.
7. Motor is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.
8. Frequency converter is used to change the frequency and voltage of motor power to realize the function of speed adjustment control of motor.
9. 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
