Gantry crane - is a type of bridge.Unlike the latter, the bridge device that moves on rails, not directly but through a special support.Sami rails are installed at the same time is not high on the walls of the shop, and on the ground.The key feature of equipment such as cranes, is their versatility.

There are both single-girder and double-girder design.Any kind of equipment requires little maintenance and is easily operated by one operator.The use of such structures as the bridge gantry crane, will help increase the productivity to a great extent.According to the experience of using such models the costs of the output thus can be reduced by about 25%.

This equipment is used in many industries.The following are the main fields of application:

  • stock.In these spaces gantry cranes used for moving cargoes, containers, etc.
  • open areas of production facilities.In this case, the equipment is also mounted for movement in the main pieces of product.
  • When installing prefabricated buildings - warehouses, industrial and civil buildings.
  • in shipbuilding and hydropower.

In all these cases, the valves may differ slightly in performance.When used for the movement of goods in warehouses using equipment with a sufficiently small lift height (12 meters).For the installation of prefabricated structures in industry and agriculture are special assembly and construction cranes.For the movement of goods in the shipbuilding industry also apply special model.Most often it is the CCR.Produced and lightweight design that can be used even in the individual building.Such models are of extraordinary smoothness, and so it is very easy to operate.

to move the cargo itself can thus be used a variety of tools: hooks, as the Horned and the two-horned, electromagnets, tongs, grabs (special buckets, tongs, used for carrying bulk cargo), etc.Himself lifting mechanism is located directly on the bridge, and on which moves.Work of gantry crane operator can be performed either from the cab mounted on a support or a trolley, or from the outside, from the ground.In the first case, some models can be equipped with remote control.This control is used for special key, without which neither the turn nor impossible to turn off the engine.

It is this kind of bridge cranes is considered the most popular and frequently used.The point here is ease of assembly, transportation and management.In addition, this equipment is not too expensive, and fuel consumption is very little.Most are easy to maintain overhead traveling cranes.Such an interesting name, most likely chosen for these models because they are somewhat similar to the old device for cutting firewood.Between the two supports situated bridge and moves thereon one or more trolleys.
