Abstract

The invention discloses a hoisting trolley for a double beam bridge crane. The hoisting trolley comprises a trolley frame, traveling wheels are installed at the bottom of the trolley frame, a first hoisting component and a second hoisting component which are independent are arranged on the trolley frame, the first hoisting component comprises a first driving device, a transmission component, a first decelerating mechanism, a first winding drum, a first fixed pulley set and a first hoisting hook, and the second hoisting component comprises an operation driving device, a hoisting driving device, a second winding drum, a second decelerating mechanism, a second fixed pulley set and a second hoisting hook. Since two independent hoisting units are integrated into the trolley, the hoisting trolley for the double beam bridge crane has the advantages of compact and reasonable structure, high hoisting weight, small size, wide service range and safety and reliability in operation.

Description

technical field [0001] The invention relates to a double-girder bridge crane, in particular to a lifting trolley used for the double-girder bridge 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. [0003] 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. [0004] 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 th...
