Hoists of superior design
All our hoists are engineered to very high tolerances to ensure smooth running and long life. The option of the axial piston motor (made only by Gardner-Denver) offers an extra standard of performance. Using less air than a rotary vane motor, the axial piston design adds high torque and smooth operation to a hoist that is powerful, relatively small, compact, economical and quiet. Another example of high quality engineering from Gardner-Denver, designed to improve your efficiency. Hoists that are flexible
The wide range of hoists that are available from Gardner-Denver means that every application requirement can be suited. Because of the limitless combinations of power, speed, weight, size, mounting, and materials ? your hoist becomes as flexible in its application solutions as you need it to be.
Rotary Vane Air Motors
Cooper Power Tools offers two types of rotary vane air motors, the large Gardner-Denver MR series (1.0 to 7.5 hp) and small to medium sizes (.14 to 2.3 hp) in the Dotco, Buckeye, and Gardner-Denver product lines. All motors feature durable construction with precision heavy-duty bearings throughout, and multiple blade rotors for smooth power. There is a wide range of speeds and torques as well as a choice of foot, face, or flange mounting. These motors require only air line lubrication for long, trouble-free service. Mount the lubricator as close to the motor as possible. Axial Piston
These small, lightweight Gardner-Denver motors are ideal for installation in close quarters. The rugged construction and precision manufacturing of these motors allows long life with minimum maintenance. Generous size spindle bearings permit overhung weight on spindle with no external support. High torque is an inherent characteristic of piston type air motors, making them especially desirable for applications involving heavy starting loads. The overlap of power impulses in axial piston air motors provides even torque and full power in either direction of rotation. These motors should be operated under load and horizontally. Axial piston motors are ideal for start stop operations. It is not recommended that they be operated at speeds greater than 75% of free speed. Their enclosed type construction allows operation in corrosive or dusty atmospheres.
Radial Piston
Heavy-duty construction make these motors suitable for continuous operation. The counterbalanced crankshaft is supported by anti-friction bearings. A slinger distributes oil to all moving parts of the motor. Oil level and drain plugs are easily accessible. High torque is an inherent characteristic of piston type air motors, making them especially desirable for applications involving heavy starting loads. The overlap of power impulses in radial piston air motors provides even torque and full power in either direction of rotation. At least two pistons are always on a power stroke. These motors should be operated under load and in a horizontal position. It is not recommended that they be operated at speeds greater than 75% of free speed. These motors perform satisfactorily in high temperature areas up to 200° (93° C). It is recommended that air lines be equipped with lubricators. Mount the lubricator as close to the motor as possible.
