Abstract

The invention discloses a bridge crane with a high-strength main beam, and relates to the technical field of bridge cranes. The use flexibility is improved; the device specifically comprises a mounting seat and a main beam, a hoisting mechanism is mounted on the mounting seat, first electric control wheels are mounted at the bottoms of the two sides of the mounting seat, a track for the mounting seat to move is arranged on the main beam, and the first electric control wheels roll in the track; and the hoisting mechanism comprises a winding wheel and a winding motor, and the winding wheel is rotatably mounted at the top of the mounting seat. By arranging the second lifting hooks, the first lifting hooks and other structures, the four second lifting hooks can be detached for use according to the actual situation, lifting is conducted in a four-point lifting mode, the four connecting bases can be combined together according to the requirement, connectors are inserted into the four arc-shaped grooves, and the four arc-shaped grooves are matched with the four connecting bases. Then the first connecting pin and the second connecting pin are sequentially inserted for fixing, the purpose of combining the second lifting hook and the first lifting hook is achieved, the first lifting hook is used for lifting, and the use flexibility is improved.

Description

technical field [0001] The invention relates to the technical field of bridge cranes, in particular to a bridge crane with a high-strength main girder. Background technique [0002] The bridge crane is a lifting device that is placed horizontally over the workshop, warehouse and stockyard for material lifting. It is the most widely used and the largest number of lifting machinery; its two ends are located on tall cement columns or metal supports. , shaped like a bridge; the bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment; although the current bridge cranes can meet certain requirements Use requirements, but when lifting different objects, the attitude structure of the spreader cannot be adjusted according to the actual situation, and the flexibility of use is poor, so it needs to be improved. ...
