Main Differences between a Hoist and Crane

An overhead crane is a tool that has many different features and functions, and can sometimes confuse people when differentiating their types. For those who are in the market for their first cranes or simply for a new crane, should understand that there are a handful of different types. An overhead crane is a blanket term for types of cranes, and so within the world of overhead cranes, you have a multitude of options. This includes: bridge cranes, jib cranes, gantry cranes, and workstation cranes. Each of these cranes functions differently, so there is an important distinction that allows industries to do specific work. Although each crane is important in its own right, the two most popular are: gantry and job cranes. The rest of this article will be devoted to explaining the difference between the two types of overhead cranes.

A gantry crane has a lifting system that is part of a trolley. The trolley is affixed to a bridge that runs across the ceiling of a facility. The bridge stands up with the support of supporting uprights. If you know your factory will not change, you can have the supports planted in the ground, but they do not have to be. The supports can sit on wheels, allowing the whole system to be moved. The wheels can help if you need to move your device and if surfaces are uneven in your facility. The wheels also give you the option to work both inside and outside. These overhead cranes can be likened to bridge cranes, but gantry cranes are cheaper to build, buy and maintain.  The cranes are tall (up to 150 ft.), and are also incredibly strong (lifting up to 150 tons). The devices are easier to install because there is no need to build a runway structure.

A jib crane is a better option for companies who know that they do not need to move their crane from place to place. Jib cranes can be affixed to either the floor or wall. Hoists and trolleys are placed on a boom that pivots. A wall mount can pivot 180 degrees, where as a floor jib crane can pivot 360 degrees. In certain cases, portable jib cranes can be built as well. The machines can be used manually or with the help of motors. This crane is great for lifting heavy items and moving them shorter distances, making them the best cranes for the use in an individual workstation. A welding, assembly, and fabrication station are some of the areas where you can find them being used.  These devices can only lift up to 10 tons, making them less strong than gantry cranes.

Make sure you find out about all of your options so you can get the best overhead crane possible.
