Cranes, gantry cranes, semi-gantry cranes, monorails and jib cranes are used as a mechanical equipment in factories, warehouses, quays, etc. in order to rationalize the way of moving heavy goods so that the human handling operation can be reduced while the productivity can be increased.


Normally cranes are designed and manufactured with the box-framed shape, proportional, endurable. The normal material is shaped steel and sheet steel. The connection between the material is based on the bolts and welding texture. After finished manufacturing and installing, cranes are tested to ensure they meet the technical requirement.
The main components of a crane including main girder, beam, hoist, control box, geared motors, electric system, etc.


Based on the texture, cranes are differentiated into many types such as single girder crane, double girder crane, underhung crane, gantry crane, semi-gantry crane, jib crane, etc…

  • Double girder crane:to optimize the scope of operation area and to minimize the area of a crane in a factory. The structure is simple but high adaptable: speed and control can be changed based on each usage purpose.


  • Double girder gantry crane: high mobility and, strong structure, work well outdoor
  • Semi gantry crane: Can be used in a workshop/warehouse or outdoor
  • Single girder crane:
