Gantry cranes depending on appointment are divided into the following groups:
- cranes of general purpose – are used to service of ground storages and loading platforms;
- cranes construction – are used to installation of combined construction constructions and the equipment of the industrial enterprises;
- cranes of a special purpose – are used to service of hydraulic engineering constructions, an overload of lengthy freights and large-capacity containers.
Gantry cranes are manufactured mainly hook (more rare clamshell and magnetic) or with special captures.
Gantry cranes of general purpose have the loading capacity from 3,2 to 50 t, flights of 10 - 42 m, with a height of rise of 7 - 15 m.
Depending on bridge type gantry cranes are subdivided into one - and two-frame. Cargo carts of one-frame bridges carry out suspended monorail (at loading capacity to 16 t use self-propelled electric waists), suspended double-track, console and console and suspended. On gantry cranes with two-frame bridges use, as a rule, cargo carts of bridge cranes. Cargo carts are carried out both with the individual drive of the mechanism of movement, and on rope draft. The mechanism of movement of the cart on rope draft creates smaller load of a metal construction and provides exact positioning of the cargo cart on the bridge of the crane (resistance to a freight swing).
Gantry cranes are manufactured mainly two-console. Apply to installation works beskonsolny or with one console. Support of gantry cranes carry out two-rack-mount equal rigidity or one rigid, and another hinged.
Construction gantry cranes have loading capacity to 400 t, flights – to 80 m, rise height – to 30 m. Such cranes are equipped with such load gripping bodies as a hook or a traverse, and have rather slow (assembly) speeds of mechanisms, for ensuring accuracy of positioning and installation of combined construction constructions and the equipment.
Gantry cranes of a special purpose have parameters over a wide range: loading capacity – 900 t, flights – more than 130 m, rise height to 80 m, are also projected under concrete requirements of technological process in which are involved.
