Boom lifts and cherry pickers are varieties of aerial work platform (Awp) or mobile elevating work platform (Mewp). Also known as powered access machinery, these lifts provide temporary access to otherwise inaccessible areas using extending mechanical platforms. Some Awps only enlarge in one direction, for example scissor lifts, which move vertically on a concertina device. Boom lifts and cherry pickers have the benefit of outreach as well as height, and are more versatile.
There are various types of boom lift and cherry picker. Some have further outreach or a higher working height than others, but all succeed the same principle. A platform or pail is attached to the boom, which can enlarge upwards and from side to side, or contains hinges that allow it to provide an 'up and over' movement. The operator works on the platform, protected and contained by a cage or safety rail, and is raised to the proper height or position safely, either by controls on the platform itself, or by a second operator at ground level.

Stick booms provide height and outreach, but only enlarge vertically and rotate laterally. Articulating booms and cherry pickers allow for more accurate access to difficult to reach areas, for example to accomplish maintenance and repairs on an aircraft. Booms and cherry pickers are the closest version of aerial platform to a crane, but are very dissimilar in the way they move and are controlled.
Boom lifts and cherry pickers tend to be larger than other types of Awp, like scissor lifts and personnel lifts, which come in compact and narrow versions for use in warehouses and offices. Boom lifts, therefore, are often used on large-scale projects such as construction and events. The very largest platforms, mounted on a truck or lorry, can enlarge their telescoping sections to a height of more than 100 metres.
Smaller booms are also available, for use in telephone and power line maintenance, window cleaning, tree surgery and fire fighting. And, of course, the former use to which cherry pickers were put - harvesting fruit!
These types of Awp are commonly powered by diesel, due to their weight, but some of the smaller versions may be powered by Lpg, electricity, battery or pneumatics. Some are self-propelling, while others are mounted, or are fitted with legs, and are known as spider lifts. Spiders are beneficial in areas where the lift must manoeuvre through narrow doorways, or to provide stability on uneven ground.
Most powered access providers offer boom hire as well as new and used boom lifts and cherry pickers for sale. Discuss your needs with your local provider to see what they have to fit your requirements.
