Description
H-4 OR BETTER-RATED DUTY CYCLE:
- Designed for heavy-duty industrial applications from 2 to 20-ton capacities. Enclosed, ball bearing, 30-minute rated, thermally protected, hoist duty motor is standard. Heavy-duty, industrial single-speed controls include magnetic reversing contactor which operates on 115 volts provided by a control transformer. Dual braking system.
BUILT FOR SAFETY AND DURABILITY:
- Liftwheel 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. Hoistaloy load chain can be easily inspected for wear and abuse. Extensive use of life-lubricated bearings plus sealed oil bath power train reservoir for minimum maintenance.
SINGLE OR TWO-SPEED CONTROLS:
- Two-speed models operate on 3:1 speed ratio. Motors up to 7 1/2 h.p. provide a wide range of lifting speeds. Push button control is weatherproof (NEMA 4 rated).
STANDARD LIMIT SWITCHES AND OVERLOAD PROTECTOR:
- Standard adjustable upper and lower screw limit switches. Standard overload Protector device.
RUGGED AND LIGHTWEIGHT DESIGN:
- Rugged aluminum alloy hoist frame. Chain guide surrounds liftwheel. Machined and hardened steel Helical gears used throughout hoist for optimum performance and mechanical efficiency.
TROLLEY OPTIONS:
- 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.”
ADDITIONAL INFORMATION:
- True vertical lift. Factory tested to 125% of rated capacity prior to shipment. Metric rated except for 10 & 20-ton capacities. Drop of push button control is 4 ft. above hook at the lowest position, unless otherwise specified. External push button chain strain relief is standard. Power cord length is 2 1/2 ft. unless otherwise specified. Weatherproof (NEMA3R). Lifetime warranty. Up to 600 lineal feet of chain.
