Classification of Single Girder Gantry Crane

 Single girder gantry crane can be divided into box type and truss type.

Box type

The box type single girder gantry crane is a medium sized crane, travelling in track , usually equipped with standard CD MD electric hoist as the lifting mechanism, and the electric hoist traversing along the lower flange of the I- steel of the main girder, which is made of high quality steel plates, such as, C-steel and I-steel.

Truss type

The truss single girder gantry crane differentiates itself with the box type crane in terms of structure construction. The former is made of steel bars and the latter is made of steel plates. The truss gantry crane is much lighter than that of the box type gantry crane and it has high wind resistance.

Wire Rope Electric Hoists Inspections

  1.Wire rope electric hoist motor temperature rise is too high. First of all, check whether the  wire rope electric hoist  is overloaded. The overload causes the motor to heat up. Then check whether the motor bearing is damaged or not, and whether the motor works according to the regulations. When the motor is running, if the brake clearance is too small, will generate a large frictional force. The frictional heat also increases the additional load. 2.Wire rope electric hoist can not start after heavy objects rise to mid-air, or after parking can not re-start. First check if the system voltage is too low or the fluctuation is too large. If it is, restart it only after the voltage returns to normal. On the other hand, if it cannot be started after stopping, pay attention to whether there is a phase loss in the operation of the three-phase motor. 3.Can not stop working. The power should be cut off immediately, the wire rope electric hoist should be forcibly stopped, and the repair the c
