In the world of overhead cranes, no two systems are alike. Each is designed for a specific application, and some are custom fabricated for an individual environment. Today, we look at a few of the different types of cranes and offer tips on choosing which is right for your manufacturing floor.
Overhead Traveling Bridge Crane
The largest of the overhead cranes, an overhead traveling bridge crane is almost always custom built to fit a building’s length, width, and height. These are often designed as a double girder bridge arrangement but, depending on its intended application, may be built with a single girder. As far as hook movement goes, an overhead traveling bridge crane operates on three axes, allowing position flexibility.
A monorail crane is an extremely customizable design built to move around obstacles. If you look at an assembly line with overhead cranes, chances are good that at least one is a monorail design, which can be spotted by its curved overhead rails. Unlike an overhead traveling bridge crane, a monorail only works only on an up-and-down axis.
Jib cranes may be installed against a wall or freestanding. These may rotate up to 360° and, in most cases, are permanently mounted over a singular location.
Freestanding (sometimes called workstation) cranes are overhead cranes built for effortless movement. They feature enclosed tracks with a 2° taper, which keep the trolley wheels centered and prevents dirt and debris buildup.
Gantry cranes are typically more affordable than standard overhead cranes. These are often designed to be portable for movement between one side of the building to another, and they may be seated inside of a pre-installed track. Some gantry cranes utilize a V-groove caster, which allows for straight movement over long distances.
Which Type Of Crane Should I Choose?
Choosing between overhead cranes takes lots of careful consideration and a full evaluation of your intended applications. For example, you must know whether the bridge will be supported by the building or self-supported. You also need to speak with your representative about whether you need a motorized or manual design.
Your overhead crane system is an integral part of your business. Like other major business decisions, you must do your research and know exactly how your device will be used before you get started.
