Single girder gantry crane buffer device has what?

    Single girder   steel crane   simple structure, easy installation, the quality of their small, mostly off-track girder box-shaped frame structure. And double-girder gantry crane compared to the overall stiffness is weaker. Therefore, when the starting weight Q ≤ 50t, span S ≤ 35m, we can use this form. Single girder gantry crane doors legs with L-and C-type forms. L-manufacture and installation convenience, the force is good, the quality of their small, but, lifting cargo space through the legs at a relatively small number. The feet made ​​of C-inclined or curved shape, the purpose is to have large lateral space to pass the goods foot.

       Single girder   bridge gantry crane   buffer device is divided into three categories: physical buffers, spring buffers, shock absorber

      One is the physical buffer. Buffer is divided into physical and polyurethane rubber buffers buffer. Both have their own characteristics, rubber buffer structure is simple, can play a role in blocking, while its low price, long life, installation and maintenance is also very convenient, thus Polyurethane buffers currently in the more extensive use of international .

       One is spring buffer. Spring buffer structure is very simple, of a total of three parts, namely, meet, springs and housings. Its main task is the principle of spring buffer   hoist gantry crane   crash when the energy can be transformed into a compression spring, in order to prevent accidents, ensure the single girder   overhead bridge crane   safety and reliability.

      Finally, hydraulic buffers. This buffer works is when a single girder gantry crane collision, hydraulic buffers to allow all parts of the crane through a process in order to play a buffer role.
