摘要:
An emergency movement device for a lift has a mounting body attached to the lift and a pivoting body pivotally attached to the mounting body. A gear box with an output drive shaft for engaging a main drive of the lift is provided. The output drive shaft is movable in conjunction with the pivoting body. The pivoting body is movable between an engaging position in which the output drive shaft engages the main drive to allow for rotation of the main drive of the lift and a non-engaging position in which the output drive shaft is disconnected from the main drive. An input shaft is provided and has a first end and a second end. The first end is connected to the gear box to allow rotation of the input shaft which causes rotation of the output drive shaft. An input shaft support is positioned on the lift for providing support to the input shaft so that the input shaft is supported in a substantially horizontal orientation. A biasing spring is provided in communication with the pivoting body for biasing the pivoting body and the output drive shaft in the non-engaging position.
