A Guide to the 5 Essential Crane Components
Without cranes, it would be practically impossible to move heavy construction materials around job sites. However, not all cranes are the same, and understanding crane components can help you choose the right machine for every job.
As the most respected crane contractors and crane rental services in Arizona, we take pride in matching the right equipment to customer needs. So we prepared this guide to help you understand some of the basics and things to consider when scheduling equipment.
The Two Types of Cranes
Builders use two types of cranes: tower or telescopic. Tower cranes remain in one place but rest on a turntable that allows them to move horizontally. Telescopic cranes have wheels or tracks that let them move around the worksite, adjusting the boom to different heights as necessary.
Although these machines have some key variations, they share many of the same components. Here are some you’ll find on every crane.
1. Outriggers and Counterweights
Hooking a heavy load to the front of a crane without counterbalancing it on the back can cause the machine to topple over. Outriggers and counterweights prevent this. Every crane has counterweights for extra stability and weight distribution.
2. Boom
The main boom, or mast, extends from the crane base and provides height. These crane components may use hydraulics that allow them to stretch to reach varying heights or lattice booms, which have a fixed position.
Lattice booms have steel bars welded together in a crisscross pattern, evenly distributing weight and increasing the crane’s lifting capacity. However, telescopic booms are better for smaller construction sites or projects that require greater precision.
3. Jib
The last thing you want is for the load to hit the crane body, so cranes have jibs that extend out horizontally to ensure plenty of space between the boom and the load for crane safety.
4. Hoist
Hoists make it possible for the crane to lift materials off the ground. Without them, the machines wouldn’t do anything at all. A hoist has a crank, a winding drum, and a wire rope that raises and lowers the hook.
5. Hook
Arguably, the most important part of the crane, the hook, connects the load to the hoist. Hooks are the only connection point between the crane and whatever it needs to move, so they have to be exceedingly strong.
When not in use, the hook remains part of the hook block, a rugged steel block that contains the bearings, sheaves, and pulleys that allow it to function. This block also maintains tension on the wire rope when cranes aren’t in use.
