Your job is on a mining site and you need to lift below the level the cherry picker sits on (a mix of outreach and jib rotation) You need your cherry picker to lift up and over a high fence or wallĪn articulating boom will be best for this. What do you need your cherry picker to do? Selecting the right cherry picker is a combination of thinking about the task at hand, assessing the worksite, reading specifications on the cherry picker, and looking at brands/models and their performance. You can find whether a machine has this capability on the respective boom lift’s spec sheets) This is only available on larger machines, typically the straight booms. Below reach (machines that can extend downwards, which is achieved with a mix of outreach and jib rotation.Up and Over (available with knuckle booms, where the basket can be raised up, then the top section lowered down from one of the ‘knuckle’ points).Jib/Basket rotation (the movement of the basket at the point of the boom).Vertical lift/Outreach (movement of the boom or ‘mast’, either outward, or up and down).Slew movement (movement of the body of the machine).The five main movements a cherry picker is capable of are: Towable boom lifts are generally battery or gasoline powered. They can be towed behind a vehicle, so in a sense they are convenient, however mobility once on site must be considered, as they will need to be towed between site locations when changing between tasks, and this will require a vehicle. Towable boom lifts have an articulated boom and a turntable attached to a trailer chassis. Painters, warehousers and roofers find knuckle boom lifts to be the perfect tool to get them right to the job for safe and stable access. Self-propelled models come as electric indoor units for confined spaces or 4WD Diesel models which work on any terrain. The base unit can be positioned close to the job for more stability, and requires little floor space.Īrticulated booms can tackle tight indoor spaces, or outdoor spaces that may have obstacles creating narrow working areas.Īrticulating boom lifts can be self-propelled or trailer-mounted. With each section able to be adjusted independently, the articulated boom can go “up and out” or “up and over” to access varying high locations. These bends/ knuckles /joints allow the user flexibility when accessing challenging positions. The self-propelled models can be electric, or 4WD All Terrain units, which can traverse rough and rocky surfaces.Ĭonstruction and maintenance workers love the extension and stability telescopic boom lifts provide.Īrticulating booms (also called knuckle booms), have one or more bends or joints that straight booms don’t possess. Telescopic booms come in trailer-mounted or self-propelled versions. Due to its stable base, telescopic booms can generally reach greater heights than articulated booms. The scope for a telescopic boom is both high and wide, so it’s well-suited to large or open worksites as it needs a big space to reach its capacity. Hydraulics on the boom hoist are used to extend and retract the boom. The telescopic boom lift (also known as a straight boom or stick boom) has a boom that telescopes straight out from a stable pivoting base unit. Telescopic boom lifts (straight booms/stick booms) This is where the terms telescopic (straight/stick) booms, articulating (knuckle) booms, and towable boom lifts matter more. The important distinction to make is in what the EWP actually does on the job. With cherry picker and boom lift often used interchangeably, it’s best to put names aside and focus instead on function. Though not towed, it still needs to be transported to site via a truck. It’s usually self-propelled, and has the capability to move around on a job in its elevated position. What we refer to as a “ boom lift ” is slightly different. You may have heard the name “cherry picker” used to describe Elevated Work Platforms (EWPs) of all varieties, however strictly speaking, a cherry picker is a trailer-mounted boom lift (or towable boom lift) with four outrigger legs. Let's take a look at the main types in more detail. The cherry picker you need will be the one that best matches conditions on your site and meets the requirements of the job at hand. Brand names aside, there are essentially three types of cherry picker, with varied features available. When you’re organising cherry picker hire, or are considering a cherry picker for sale, knowing which unit to choose for your job can be confusing.
