A safety mechanism for preventing a cable drum to rotate with overspeed has parallel ratchet wheels which encircle a brake drum. At a periphery of the ratchet wheels are stopping slots wherein a latching pawl is inserted when an overspeed is detected. The slots of the adjacent ratchet wheels are staggered. Thus the braking effect of each ratchet wheel starts at a different point of time.

A lifting machine has a drum unit comprising a motor attached to a frame of the lifting machine, a gearbox and a rope drum, this unit being resiliently attached to the frame of the lifting machine.

Lifting machinery

In a method for the generation of control signals in a push button box and transmission of the signals for the control of a machine, signals representing the position of a push button element are transferred by a non-contacting mode from the push button element to a signal generating unit, which is adapted to produce control signals proportional to the position of the push button element. A push button box for carrying out the method comprises at least one push button element, a signal generating unit adapted to receive the signals representing the position of the push button element by non-contacting mode, and further adapted to generate control signals proportional to the position of each of the push button elements, and a partition between each push button element and the signal generating unit.

An electromechanical drive has an ac motor provided with a brake, a frequency converter provided with a control unit and supplying the motor, and a transmission gearing connected to the output of the motor. To achieve efficient cooling, the drive is provided with a cooling tunnel housing the motor and the brake; the control unit and the power stage semiconductor switches of the frequency converter are located on the outer walls of this tunnel; and the transmission gear is located in or adjacent the tunnel.

Air cooled electromechanical drive apparatus

The invention concerns a telfer carriage comprising dual end supports a supporting beam, hoisting and displacing machinery and a rope drum. To the end supports has been pivotally affixed the supporting beam lying immediately beside the rope drum and parallel therewith. The end supports have been rigidly joined together by a non-rotating axle, on which are furthermore rotatably carried, the rope drum and a carrying wheel pair.
