Cranes And Gantries – Differences And Similarities

Cranes And Gantries

When deciding to improve internal transport in an enterprise, one of the most important dilemmas is whether it is worth investing in an overhead crane or opting for a crane. Among lifting devices, these two options are the most popular, all because of their reliability and versatility.

How is an overhead crane built, and how is a crane?

A crane consists of an jib and often a pole. The crane has a load-bearing part, which is a bridge that moves on the tracks, and a lifting and driving unit. The crane track can be mounted on a supporting structure made of steel or on a building structure. What the gantry and crane have in common is that the lifting units can be suspended in both cases. Working with suspended crossbeams will be possible in the case of an overhead crane. Problems may arise when trying to hang crossbeams longer than 2 meters on a stationary crane.

How to install an overhead crane and a crane?

The crane structure can be pole-mounted or wall-mounted. The gantry can be installed into an existing hall structure or to a supporting structure. In many cases, if the shape of the building is appropriate, the crane can be hung from the ceiling. Installing a crane requires much more space than when installing a crane. The advantage is that you can opt for several hoists here. A stationary crane will work wherever there is a need to operate the position within a limited range. Mobile cranes can be easily moved.

Crane and gantry – criteria, application, type of work

The crane is suitable for situations where the transfer must be precise or when materials that are subject to exploitation in the production process need to be replaced. While the crane’s working area is determined by the spacing of its arms, the overhead cranes will serve a space similar to a rectangle and are not able to operate over a larger area. Overhead cranes have their place in the industrial, furniture and logistics sectors. Following the health and safety rules, the use of overhead cranes and cranes is as safe as possible, and all these devices must be under technical supervision.

When purchasing one of these devices, it is essential to identify:

  • what is going to pick up,
  • to what height,
  • how much do the lifted items weigh,
  • what is the precision of the task.

A gantry crane will usually be a more expensive solution, but very often it can handle several positions and tasks at the same time. If it can be positioned so that it serves multiple purposes, then the cost will be lower than it would be to purchase several cranes for this purpose. Cranes, on the other hand, are a great choice when work is spread over a large area (e.g. on construction sites).
