Abstract

The invention discloses a bridge crane with a high-strength main girder, which relates to the technical field of bridge cranes; in order to improve the flexibility of use; it specifically includes a mounting base and a main beam, and a lifting mechanism is installed on the mounting base. The first electric control wheel is installed on the bottom of both sides of the seat, and the main beam is provided with a track for the installation seat to move, and the first electric control wheel rolls in the track; the lifting mechanism includes a winding wheel and a winding motor, and the winding The wheel is rotatably mounted on top of the mount. According to the actual situation, the present invention can disassemble and use the four second hooks by setting the second hooks, the first hooks and other structures, and carry out hoisting in a four-point hoisting manner, and can also connect the four hooks according to requirements. The seat is combined together, and the connecting head is inserted into the four arc-shaped grooves, and then the first connecting pin and the second connecting pin are inserted in turn for fixing, so as to achieve the purpose of combining the second hook with the first hook. One hook is used for hoisting, which improves the flexibility of use.

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. ...
