The crane trolley is designed to install a load lifting mechanism on it and is equipped with a mechanism for moving the trolley itself relative to the span of the crane bridge. The design of the trolley is a frame welded from transverse and longitudinal beams, based on running wheels. On the frame of the trolley there is a lifting mechanism, a mechanism for moving the trolley itself along the crane bridge, a pantograph, as well as safety devices. In case of production need, two lifting mechanisms are installed on the crane trolley: main and auxiliary. The crane trolley can be of both winch and hoist type. Crane trolleys can be supplied either separately or as a set with overhead cranes.
