Features of electric hoist double girder overhead crane

• The double girder structure makes the overhead crane bridge have enough strength, rigidity and stability.
• The design of the middle rail box girder of the double-girder bridge crane fully meets the requirements of strength, stiffness and stability.
• The end girder of the double girder bridge crane has a simple design and structure, and can be easily installed with the main girder through high-strength bolts.
• The hoisting mechanism of the double girder overhead crane adopts CD or MD high-quality wire rope electric hoist.
• The double-girder bridge crane adopts a weak current soft-start motor. Ground controls are also available in conjunction with double girder overhead traveling cranes.
• The dual-motor independent drive device is used to reduce the wear and tear of the rail and reduce the possibility of failures such as wheel climbing.
• The motor of the double-girder bridge crane is directly controlled by the contactor, which can realize single-speed, double-speed and reversing control of the motor.
• The frequency converter is used on the double-girder bridge crane to change the frequency and voltage of the motor power supply to realize the function of speed control of the motor.
• The double-girder bridge crane adopts multiple safety protection systems, including short-circuit protection, no-voltage protection, emergency power-off switch protection, overload limit protection, travel limit protection, zero-sum chain protection, and grounding protection.​
