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
- 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 crane, also known as a track crane, is used primarily in the interiors of industrial halls. It is built of a truss platform, which is placed on rails installed under the hall ceiling. There is a tractor on the platform. These cranes can be operated from the working level - wired or wireless, or some are equipped with operator's 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.
