the utility model aims to solve the existing problems and provides a single-boom bridge crane.

The technical solution of the utility model is as follows:

the utility model provides a single cantilever crane bridge crane, includes the track, sliding connection has the removal wheel on the track, remove two liang of installations on the track of wheel, fixed mounting has the bearing frame between a set of removal wheel, welded fastening has the cantilever crane on the bearing frame, welded fastening has the mounting bracket on the cantilever crane, two sets of slots have been seted up on the mounting bracket, slot interpolation cover has two sets of symmetrical slide rails, fixedly connected with crane span structure on the slide rail, the both ends integrated into one piece of crane span structure has the articulated slab, sliding connection has hoisting apparatus on the crane span structure.

As the preferred technical scheme, hoisting apparatus includes crane boom, driving motor case, leading wheel, assembly pulley and lifting hook, the top surface of crane boom is provided with the driving motor case, the four corners department fixed mounting of crane boom bottom surface has the leading wheel, the leading wheel slidable mounting is in the slide rail, the shaping has the dead slot on the crane span structure, the assembly pulley passes the dead slot and is connected with the driving motor case transmission.

As the preferred technical scheme, the pulley block comprises a steel belt, a movable pulley, a connecting plate and a lifting hook, and the lifting hook is provided with limiting teeth.

As a preferred technical solution, the number of lifting devices is two.

As a preferred technical scheme, a plurality of groups of supporting plates are arranged on the inner wall of the arm support.

The utility model has the beneficial effects that: according to the utility model, the support plate is arranged in the arm support, so that the structural strength of the arm support is enhanced, and the stress surface of the crane on the bridge frame is wider by improving the structure of the crane device, so that the transportation tonnage of the crane can be increased; set up two sets of hoisting apparatus and through motor automatic control, the efficiency that improves cargo transportation also can carry out multiple type transportation and improve the practicality of hoist, sets up the spacing tooth of one-way opening on the lifting hook, can prevent to take place the condition that the goods dropped in the transportation, avoids taking place the incident.
