Abstract

A hoist, including: load suspension device, a lifting means for raising and lowering the load suspension device; a traction mechanism connecting the suspension device with the lifting device; and a control device for the lifting device and the load suspension device. The control device is connected with the load suspension device and including a housing, a handle for manipulating the load suspension means, switching members arranged in the housing which are actuable for controlling the lifting device, and switching rockers arranged in the housing so as to be able to actuate the switching members. The switching rockers are each inclined toward the handle and are swivable around and connected to one end of a rocker shaft extending horizontally when the control device is considered as vertically suspended from the traction mechanism. The switching members are located so as to be reachable by a thumb of an operator's hand grasping the handle, while the handle is curved so that an imaginary line continuing from an outer surface of the handle intersects each of the switching rockers near supporting surfaces of the switching rockers. The supporting surface of each of the switching rockers…
