In the United States, at the GMS Industries plant at 807 West 4th Street, Buchanan, MI 49107.

Four product lines:

Air Motors: AMP-200, AMP-180, AMP-94, AMP-38, AM-2.

Winches & Hoists: AW-80, D-COK-R, EW-111, JHA(L)-20, JHA(L)-40, JHA(L)-60-(24 & 30), LF-113, AF-112, JHA-100, OS-111(A)(B).

The AMP series (AMP-200, AMP-180, AMP-94 and AMP-38) are radial five-cylinder piston air motors, also called Pistonair motors. They deliver high torque at variable speed and are reversible. Each is offered direct drive on a flange or foot mount, or with a geared foot mount in several ratios for higher torque at lower speed.

Maximum horsepower by model: AMP-200 — 20.0 hp at 90 PSI (direct drive); AMP-180 — 18.0 hp at 90 PSI (direct drive); AMP-94 — 9.4 hp at 90 PSI (direct drive); AMP-38 — 3.9 hp at 100 PSI (direct drive).

Air consumption at maximum horsepower: AMP-200 580 CFM, AMP-180 530 CFM, AMP-94 285 CFM, AMP-38 110 CFM. The compressor must be able to deliver that volume at the motor inlet for the motor to develop its rated horsepower.

Minimum air supply line size: AMP-200 1¼ in minimum; AMP-94 1 in minimum; AMP-38 5/8 in minimum, ¾ in preferred.

The manuals call for 100 PSIG at the motor inlet during operation for best performance, and for the air supply to be dried, filtered with a strainer, and lubricated with a line oiler close to the motor.

No. AMP motors are drained before they leave the factory and ship without oil or lubrication of any kind. Fill the motor before turning on the air: approximately 1 quart for the AMP-200 and AMP-94, and approximately ½ quart for the AMP-38, then top off as the manual describes.

After filling, run the motor slowly at low pressure for several minutes before putting it under load. Never start a motor at maximum pressure after installation or an oil change.

No. The operating manuals state that this equipment and its accessories are not to be used for lifting or lowering people, and the AW-80 specification sheet states the winch is not designed or approved for lifting people.

The document library on this site has free PDF downloads, each checked against the model it covers. Every PDF is text-searchable.
