Control-head for handle-operated motorised loading trolley

摘要

The handle control-head on the end of a pole used to guide a motorised trolley has operating switches for forward and backward movement as well as for raising and lowering the loading platform. They have a safety function and work with electrical signal transmitters in the handle. The transmitters are on a common circuit board in a one- or multi-part plastic carrier which is detachable from a recess in the handle. The circuit board has a common plug connector with a cable for all the transmitters. The handle has an element which gives an acoustic warning signal, in conjunction with one of the signal transmitters i.e. microswitches.
