Types of Overhead Cranes that You Can Rent from Crane Hire Companies

August 28, 2020

Most crane hire companies have a wide variety of crane options. Some of their cranes are intended to be mobile, allowing the transfer of equipment and heavy loads to be easier and more versatile. Another type of crane is mounted on an undercarriage with four strong wheels, making it suitable to rough terrain. Overhead cranes, conversely, are mostly utilised by factories, shipyards, and large outdoor manufacturing plants due to their available functions and abilities.

Overhead cranes are equipped with a travelling bridge that spans the gap. The hoist of these cranes is installed on a trolley so that it can move in a single direction along the beams of the bridge. This type of cranes is mostly maximised in industrial environments because of their ability to lift and move very heavy loads and materials. Most overhead cranes would have this default composition. However, some types of overhead cranes are equipped with some enhancements for them to fit in with specific tasks or locations.

Some types of overhead cranes that can be rented from crane hire companies are:

Bridge Cranes

Bridge cranes are considered to be the largest among all the types of overhead cranes. They typically span between two overhead runway beams and can be further classified into double-girder bridge cranes or single-girder bridge cranes. The hoist of these cranes can move upward, downward, or sideways across the bridge, which is very helpful in loading, unloading, and arranging heavy metal containers. 

Gantry Cranes

Gantry cranes, on the other hand, have two legs that can support their trolley, bridge, and hoist. The legs of these cranes can easily extend down to wheels on the ground, allowing them to support any heavy load. These cranes typically have underhung hoists that do not move on runways. Instead, these hoists move on embedded rails that are situated on the floor. These cranes are perfect for railyards and shipyards. They can also be used during the construction of bridges or steel mills.

Monorail Cranes

Monorail cranes are mostly maximised in factories, manufacturing plants, and other related facilities due to their functionalities. These cranes do not rely on a bridge or girder design, but they can still easily move heavy materials across a straight, predetermined route since they are connected to l-beams. Aside from running back and forth in a straight line, they can also move heavy loads in curved tracks, branches, and switches. Changing the elevation of the path is also possible with monorail cranes. 

Jib Cranes

Jib cranes may be small, but they can still offer numerous functions thanks to their overall structure. This type of overhead cranes can offer both 180-degree and 360-degree rotations, hoist heavy load and materials, and move them into small access areas. These cranes can be either stand-alone or be mounted on columns or walls. They are mostly ideal in small spaces due to their compact form factor. 

Workstation Cranes

Workstation cranes are also compact, but they can still provide comfort to small work areas. Installing these cranes do not need an existing support structure, allowing them to be placed in any types of workstations. They can lift materials for up to 2 tonnes in weight capacity and perform repetitive lifting and positioning of loads during an entire working schedule.

Different work requirements entail the need to use a specific type of overhead cranes. Knowing the qualities of each type of overhead crane allows you to pick and hire the most suitable one for your site, plant, factory, or facility.
