Since then, Rotary Lift products have come to be used in automotive repair contexts throughout the world, and other companies have followed Rotary Lift’s example with their own lines of vehicle lifting products. Every automotive repair and service operation requires access to vehicles from all angles.
A vehicle lift, which is one type of rotary lift, gives technicians access to all of the components that are only accessible from a vehicle’s underside.
Different kinds of lifts are necessary to accommodate the many vehicle shapes, sizes and configurations in existence. Rotary Lift’s line of vehicle lifts includes light-duty two and four post lifts, in-ground lifts, heavy-duty two post and four post lifts, mobile column hydraulic lifts, parallelogram lifts, pit lifts, suspended pit lifts and several other hydraulic lift varieties.
They can be used to lift passenger cars, school buses, industrial vehicles like dump trucks and many other kinds of vehicles. Rotary Lift’s vehicle lifting products are distributed by many companies throughout the United States and in international markets.
Almost all vehicle lifting products are examples of hydraulic lift systems. Comparatively light weight vehicles like golf carts may be lifted by electric lifts in some cases, but for the reliability and strength required to lift an automobile, a hydraulic lift is almost always necessary.
Hydraulic lifts are powered by the force of compressed hydraulic fluid; these fluids are usually oils or synthetic materials that resist compression. When a sufficient volume of hydraulic fluid is forced into a hydraulic cylinder, the force exerted by the compressed fluid is enough to lift objects as heavy as dump trucks.
All hydraulic cylinders involve a reinforced enclosure, several seals and flanges, a piston, a connecting rod and hydraulic fluid in variable quantities. When hydraulic fluid is forced into the cylinder, it causes the piston to move.
The piston is attached to a connecting rod, which is itself connected to load bearing surfaces; in the case of Rotary Lift’s products, these load bearing surfaces are vehicle lift platforms or arms.
The force of the compressed hydraulic fluid can keep a vehicle lifted without failure practically indefinitely, assuming the cylinder is inspected regularly and operated within the boundaries of its determined load capacity.
