Selection of Gantry Crane

Selecting the right gantry crane is critical to ensuring your work efficiency and safety. In the selection of a gantry crane, you need to consider a few things so as to identify the right one for your application.

  • Selection of single girder or double girder gantry crane

The selection of single or double girder is determine by the rated lifting capacity, working speed and size of load. In general, the single girder gantry crane can be used when the lifting capacity is below 50 tons and the span is within 35m. If the width of the gantry legs is required to be large, the working speed is high, or heavy and long pieces are often hoisted, a double girder gantry crane should be selected.

  • Span and cantilever length

The span of a gantry crane is an important factor affecting the weight of the crane itself. The span length should be minimized on the premise of meeting the conditions of equipment use and meeting the standard of span series.

  • Determination of the track

It should meet the stability requirements of the gantry in the direction of the crane track.

The overall dimensions of the cargo must be able to pass through the flat steel frame of the leg smoothly.

The wheelbase (B) is proportional to the span (S). Generally, the wheelbase B = (1 / 4-1 / 6) S.

  • Determination of gantry crane pitch size

During operation, there should be a certain space size between the external dimensions of the gantry crane, the cargo in the yard and the transportation vehicle passages to facilitate loading and unloading operations. When loading and unloading within the span, the transport vehicle shall maintain a distance of more than 0.7m from the support legs. When not working, the spreader should have a distance of more than 0.5m from the transport vehicle, and the cargo should have a distance of more than 0.5m when it passes through the support legs.
