Continuous Duty— Precise Positioning

AC Model Air Powered Hoist

COFFING AC Models – Air chain hoists featuring continuous duty service for precise, infinitely variable speed and accurate load spotting.

  • CAPACITIES & LIFT – Rated loads 1/4 to 6 Tons. 10, 15, and 20-foot standard. Other lifts available.
  • CONTROLS – Standard rope pull cord is 3-feet less than lift. Optional twist rod, lever pendant, and hook-mounted controls available.
  • SUSPENSION – Swivel top and bottom hooks with safety latches stan-dard. Air trolley available in 3 and 6 tons — consult factory.
  • SPEEDS – Precise and infinitely variable speed control for accurate load spotting. 90 PSI air operating pressure.
  • COMPACT CONSTRUCTION – Ideal for use in areas with restricted space. Lightweight and portable – 1/4, 1/2 & 1 ton units weigh less than 50 lbs.
  • MOTOR – Rotary vane type motor provides for high uniform torque and quick response. Bronze muffler built into valve housing for quiet operation.
  • PLANETARY GEARS – Designed to withstand continuous operation at full load. Permanently lubricated for long life.
  • DISC TYPE MOTOR BRAKE – Releases automatically when motor shaft rotates in hoisting direction and sets with slight motor shaft rotation in lowering direction. Designed to eliminate load drift.
  • MAIN VALVE – Air balanced, spring centered unit provides smooth starts and excellent inching characteristics.
  • LIMIT SWITCHES – Upper and lower paddle limit switch with plugging to regulate load travel.
  • LIFETIME WARRANTY

NOTE: For complete dimensional data, refer to Coffing Dimensional Databook.

Air Consumption Data Note:

Speed and air consumption figures should be used only as estimates of hoist performance. Actual data may vary plus or minus 15% because of individual motor characteristics. Do not operate AC hoists at an air pressure of greater than 100 psi. A1/2″ NPT air filter-regulator-lubricator is recommended for optimum operation.
