Crane and its basic structures

The gantry crane is a device that belongs to the group of cranes. It works in intermittent motion and is equipped with lifting and lowering mechanisms - with winches or hoists. Its main task is to transport materials horizontally or vertically in a designated space on its track. Its movement is also limited by the lifting and lowering height and the width of its bridge.

The basic parameters of the crane's operation are:

  • lifting capacity
  • range
  • the hight of raising
  • the speeds of the working movements
  • curb weight
  • work intensity group

There are three main crane designs:

  • overhead crane (track)
  • overhead crane
  • gantry crane

The overhead travelling crane, or cantilever crane, is used primarily in the interior of industrial halls. It consists of a trussed platform that sits on rails installed under the hall ceiling. On the platform there is a crane. These cranes can be operated from the working level, either wired or wireless, or some are equipped with operator cabins.

Gantry cranes, which are also called gantry cranes, are mainly used on shipyard inclines and landfills. They consist of a deck suspended on two bridges that connect two or more gates. They are equipped with a wheeled or rail carriages. The tractor moves on the crane bridge. The equipment is operated in a similar way as in the case of overhead traveling cranes.
