Types of Knuckle Boom Lifts

Types of Knuckle Boom Lifts

If you’re looking to buy or hire a boom lift, you might wonder which variety will work best for your job. The three types are telescopic boom lifts (straight boom lifts or stick booms), articulating boom lifts (knuckle boom lifts) and towable trailer boom lifts.

In this article we’ll run through the different types of knuckle boom lifts available.

Knuckle boom lifts vs straight boom lifts

The mast of a knuckle boom lift comes as a series of segments that connect at joints or ‘knuckles’—hence the name knuckle boom. The articulation allowed by these joints means the knuckle boom has the flexibility to offer more options in regards to how it reaches.

This flexibility means a knuckle boom is suitable for working in a wide variety of spaces, including tight spaces (indoors or outdoors), around obstacles on a worksite, and around corners. The base unit can be positioned close to the job for added stability, and requires little floor space.

Knuckle boom lifts can also do effective lateral work at varying heights, as you can easily adjust the height of the platform and move it laterally, without having to reposition the base unit. Knuckle boom lifts are especially suited to painters, caulkers, electricians, plumbers, warehousers, roofers, renderers, window installers and maintianance.

On the other hand, a straight boom lift has one long, non-articulated mast that can be extended or retracted to reach its heights, or be swung into position. It's capable of reaching “high and wide”, but not much else. To move a straight boom’s platform horisontally, you need to move the base unit, then re-swing in to get to a desired position. This is fine if you have a wide space to work in, but not ideal when space is limited.
