What is gantry crane?

A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace(https://en.wikipedia.org/wiki/Gantry_crane). A gantry crane is a very important material handling equipment in modern society. It is commonly used for loading, unloading small or large items indoors or outdoors. It can do things beyond our human capacity, and then greatly improve your productivity and save your cost.

What is a gantry crane?

A gantry crane is lifting equipment with single or double girder configuration supported by one leg or two legs. It moves on wheels or along a track or rail system. Different from overhead cranes, a gantry crane does not need to be tied into a building`s support structure.

Features

  • Full remote control and manual operation choices
  • Smooth starting and ending
  • Stable performance, less maintenance
  • High efficiency, low noise
  • Green production, no harm to the environment in the production process
  • Simple structure, easy to install, operate and maintain
  • Wide range of applications, indoors and outdoors
  • High-cost performance; low operational cost

What are gantry cranes used for?

Because of the high efficiency and good performance, gantry cranes have a highly wide range of applications. On the one hand, we can find them in indoor places, such as the warehouse, workshop, garage, manufacturing, and maintenance factory, etc. On the other hand, it is widely used for outdoor applications like the port, dock, freight yard, shipyard, etc.

Full gantry crane or semi gantry crane are commonly applied for heavy fabrication uses, or in some type of outdoor yard – shipping yard, rail and container yards, and steelyards. Portable gantry cranes are used for small service and it offers more flexibility than a jib crane or workstation crane.

Gantry crane types

We can divide gantry cranes into different types according to its structures and features, such as full gantry crane, semi gantry crane, truss gantry crane, and portable gantry crane, etc. Details are as follows:

Full gantry crane systems

Full gantry crane systems are the most commonly used configuration. It consists of two legs. It typically runs in a straight line in a work area. This system can allow it runs independently. Heavy-duty full gantry crane usually equipped with a secondary hook. This is convenient for it to lift small materials.

Semi gantry crane systems

Semi gantry crane only has one leg, and the other side of the crane riding on a runway system. This can save your floor space or workspace. Unlike a full gantry crane, it does not need much space to place two legs. It can be used both indoors and outdoors.

Truss gantry crane systems

Truss gantry cranes are usually designed as a full crane structure. And they are commonly used in outdoors. Truss cranes are not often used one, but they are quite ideal for working places where have strong winds. Because they have powerful wind resistance.

Portable or small gantry crane systems

Portable gantry crane or small gantry crane is light-duty crane systems that run on casters or rubber tries. With small size, lightweight and simple structure, it is easy to install, operate and move. Besides, it has a high-cost performance.
