Description
CM® Powerstar Electric Chain Hoist, Double Reeving, 5 ton, 20 ft Lifting Height, 8/24 fpm Lift Speed, 2-Speed Control, Dual Brake, 7-1/2 hp, 460 VAC, 34 in Lug Suspension, 36-9/16 in Trolley Suspension Headroom
Features:
- Designed specifically as an alternative to wire rope hoists for high speed lifting of loads from 2 to 20 tons in a space saving chain hoist
- H4 or better rated duty cycle, lift wheel has machined chain pockets and is heat treated alloy steel for maximum strength and wear resistance
- Efficient regenerative braking system avoids heat generation in power train
- Motors up to 7-1/2 hp provide a wide range of lifting speeds
- Single or two speed controls two speed models operate on 3:1 speed ratio
- Standard adjustable upper and lower screw limit switches
- Standard overload protector device, Hoistaloy® load chain can be easily inspected for wear and abuse and true vertical lift
- Factory tested to 125% of rated capacity prior to shipment, metric rated except for 10 and 20 ton capacities
- Rugged aluminum alloy hoist frame, chain guide surrounds lift wheel
- Machined and hardened steel helical gears used throughout hoist for optimum performance and mechanical efficiency
- Extensive use of life lubricated bearings plus sealed oil bath power train reservoir for minimum maintenance
- Heavy duty, industrial single speed controls include magnetic reversing contactor which operates on 115 volts provided by a control transformer
- Totally enclosed, ball bearing, 30 min rated, thermally protected, hoist duty motor is standard
- Push button control is weatherproof, drop of push button control is 4 ft above hook at lowest position, unless otherwise specified
- External push button chain strain relief is standard, power cord length is 2-1/2 ft unless otherwise specified
- Trolley design permits easy adjustment for installation on a broad range of beam flange widths
- Trolley wheels have double row, tapered roller bearings plus machined and hardened universal treads to permit operation on American standard or flat flanged sections interchangeably
- Spur gearing used in all motorized trolleys for improved efficiency and durability, drop of hand chain on geared trolleys is 2 ft above hook at lowest position, unless otherwise specified
- Designed to be maintained on the beam, up to 600 lineal feet of chain
