The use of special lifting equipment makes it possible to reduce the time and cost of performing labor-intensive production tasks. It can be installed in closed workshops or in specially equipped open areas. A self–propelled gantry crane, which is moved along rail rails, is a bridge-type lifting and transport equipment designed for both lifting and transporting cargo in a suspended state.
The main details of the construction:
- The bridge is a horizontal metal beam.
- Legs are vertical supports or mounted at a certain angle.
- A unit with a drum, gearbox and electric motor is a set of devices for lifting cargo by winding a cable onto a drum and moving it over a bridge.
- Roller bearings are wheels on which supports are installed to move the crane along the rails.
Electric power units are used to maintain lifting mechanisms, move the drum unit and the crane equipment itself. The prefabricated structure is delivered and installed at the site of operation with the necessary tests. It connects to the industrial network and meets the requirements of industrial safety.
The main types
Gantry cranes are classified according to their load capacity, lifting height, and bridge width. Taking into account the structural scheme, the following types are distinguished:
- Transshipment or general purpose devices — equipment is installed and used to service warehouses, assembly sites and in open areas.
- Special construction – used in the construction of new and repair of large facilities, such as bridges, tunnels or power plants.
- Non—mass-produced special-purpose products are pre-designed for specific technological tasks in ports or for servicing railway junctions or hydraulic structures.
