CONTINUOUS DUTY-PRECISE POSITIONING
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 standard. 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.
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. A 1/2” NPT air filter-regulator-lubricator is recommended for optimum operation.
