Virtually every pump hoist has the same features: a frame, an adjustable mast, one or more winches, and controls. Hydraulic pumps power all functions of the hoist, including raising the mast. Generally, a gasoline or diesel engine powers the hydraulics. Hoists of all sizes usually mount on a truck, everything from a pickup to a heavy-duty tandem-axle model.
That’s the usual setup. But I’ve seen some rather unusual hoists I consider worth mentioning. The first unusual type has a mast that swivels — not unlike a crane. I have seen these at conventions and dealer meetings, but never on a job. The swiveling mast gives this type of hoist an extra feature. The operator has the option of parking the truck carrying the hoist in different locations. They could pull a pump from the sides of the truck, not just the back. I consider this an added value.
