What is an "gantry crane"

of ensuring a flexible working environment.

What is the construction of an gantry crane?

An gantry crane consists of two stabilising feet that are attached at a right angle by a runway. "Bridge crane" is a term that is also commonly used because the machine resembles a gate. A travelling bridge spans along the runway, and can be manually or electronically operated. The hoist motor, pulley and lifting hook are attached to the travelling bridge. With its large construction, the gantry crane can cover a big working area.

What are the advantages and disadvantages of gantry crane?

The biggest advantage of an gantry crane is the large amount of space it can cover. A gantry crane can reach every point of a rectangular workspace, which is covered by its runway. The second advantage is its enduring stability; a load cannot leave the gantry crane's centre of gravitation when being transported, and therefore it will not overturn. The third advantage is its large hoisting capacity, especially in relation to jib cranes of the same size. This is due to the distribution of weight between the support points, which are relatively far apart. These three points outline why a gantry crane is superior to the jib crane. The disadvantages of gantry cranes are its size and, in relation to the jib crane, its complex construction. Gantry cranes also require an axial freedom of movement. As the runway cannot move diagonally across the room, only linear paths of movement, and therefore restricted transport of loads, are possible. Therefore, gantry cranes are used as whole room cranes and cannot, unlike jib cranes, be set up on one specific point.

What kind of facilities does a gantry crane need?

Damages to the entire machine could occur if items are placed in the path of the runway. When the crane reaches a certain size, tracks are built into the gantry crane to increase its stability and to clearly mark the path where the load is to be transported. The components of all gantry cranes, regardless of its dimensions, must be made with high-end material and have a high production quality. The drive motors for the supports are particularly important: they have to be synchronised, otherwise the crane could jam.

For the operation of a gantry crane, it is important to vigilant and adheres to the safety regulations. A variety of sizes from small, hand-operated cranes up to container loading cranes at a size of over 20 metres high are available. The biggest gantry cranes are operated from a driver's cabin, where it is required to have a crane operating license.
