Abstract

The invention discloses a crane trolley, which relates to the technical field of crane machinery. The crane trolley comprises a trolley frame, wherein travelling wheels are arranged at the bottom of the trolley frame; an operating motor and an elevating motor are arranged on the trolley frame; the operating motor is connected with a speed reducer to drive the travelling wheels to move; a winding drum is arranged on the trolley frame in a position on one side of the elevating motor; the winding drum is connected with an elevating speed reducer; the elevating speed reducer and the elevating motor are connected with each other through a coupling and a transmission shaft; a fixed pulley block is arranged on the transmission shaft; the fixed pulley block is connected with a hoisting hook through a steel wire; and the elevating speed reducer is provided with a brake. The crane trolley has the advantages of large hoisting weight, small size, wide application range and safety and reliability in running.

Description

technical field [0001] The invention relates to a crane, in particular to a lifting trolley used for lifting goods by the crane. Background technique [0002] At present, bridge cranes are widely used in indoor and outdoor warehouses, workshops, docks and open storage yards. Bridge crane is a kind of bridge type crane whose bridge frame runs on elevated track, also known as overhead crane. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides, and the hoisting trolley runs horizontally along the rails laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame for hoisting and transporting materials. Hindered by ground equipment. [0003] As we all know, the lifting trolley is an important part of the bridge crane. It is used to provide lifting power for the whole crane. The quality of its design directly determines the operation safety and lifting wei...
