EOT Crane Working Principle

EOT Crane Working Principle system consists of three working movements: crane hook up and down lifting, trolley lateral movement and crane long traveling longitudinal motion.

Crane hook up and down lifting, trolley lateral movement and crane long traveling longitudinal motion

1.Transmission of hoisting system: the driving force of hoisting mechanism is from motor. It transmits power to the high speed shaft end of reducer by gear coupling, compensation shaft and brake-wheel coupling. Then through reducer to reduce the high revolution of motor to the required revolution, and output by low-speed shaft of reducer. The ring gear of drum transmit driving force to drum set, then through wire ropes and pulleys drive crane hook up and down, so as to finish the lifting of the heavy objects up and down. 
 

2.Transmission of crane Trolley traveling system: the driving force of crane trolley is from motor. It transmits power to the high speed shaft end of reducer by brake-wheel coupling, compensation shaft and half gear coupling. Then through reducer to reduce the high revolution of motor to the required revolution, and output by low-speed shaft of reducer. And then by half gear coupling, compensation shaft, the half gear coupling joint with trolley driving wheels, so as to drive the trolley driving wheels rotating, so that finish trolley transport heavy objects by lateral movement.
 

3.Transmission of crane traveling system: the driving force of crane trolley is from motor. It transmits power to the high speed shaft end of reducer by brake-wheel coupling, compensation shaft and half gear coupling. Then through reducer to reduce the high revolution of motor to the required revolution, and output by low-speed shaft of reducer. And then by full gear coupling joint with crane driving wheel shaft, so as to drive the crane driving wheels rotating, so that finish bridge transport heavy objects by lateral movement.
