Speedway® - The New Century Series® Electric Chain Hoists 1 To 3 Ton Capacity   Standard Features Basic Controls Choose single or two speed. Magnetic reversing contactors that are both mechanically and electrically interlocked, or inverter control. 115V control circuit. Meets NEC requirements. NEMA Type 3R enclosure. Lightweight, durable, and easily accessible. Motor Brake Proven in millions of hours of in-service operation, the original WRIGHT® A-C magnet-actuated disc brake delivers rapid stops with virtually no hook drift. Rated a minimum of 150% of full load motor torque. Motor The New Century Series utilizes a U.S. manufactured 30-minute duty motor with Class F insulation. Standard single speed motor is provided for 200V, 230V/460V or 575V 3 phase, 60 hertz power supplies. Motor thermostats are standard - providing both running and overcurrent protection. Load Sheave Precision cast, heat treated, alloy steel, 5 pocket for smoother operation and increased chain life. Lubrication Gears operate in the largest oil reservoir in the industry and are enclosed in a rugged fluted aluminum alloy housing to provide rapid heat dissipation. Oil sight gauge on the housing cover permits quick visual inspection. Mechanical Load Brake Automatic Weston-Type multiple disc brake. It can hold a full capacity load independent of the motor brake and assures that the load does not accelerate while being lowered. Adjustment is not required. Gear Train Quiet helical and spur gearing. All gears are machine-cut, case-hardened alloy steel with shock-resistant ductile cores. Designed to AGMA standards. Bearings - Spider Retainer Precision heavy-duty ball bearings support all shafts. Bearings at outboard end of shafts are held in place by a heavy-duty Spider Retainer. This allows removal of Gear Housing Cover for inspection (after draining oil). All internal parts remain in place and can be operated for inspection. Load Chain Close link coil type, electric welded alloy steel, heat treated for wear resistance and ability to withstand impact.  All links precisely calibrated for uniform size and shape, free from scale and lamination to permit proper seating in the load sheave pockets.  Zinc Plated load chains are embossed with "W-6" on each link for proper identification.  The dead end of the chain is securely attached to the hoist in a manner which will permit ease of replacement. Load Block - Hook Drop forged, heat-treated steel hook swivels 360° on a shielded roller thrust bearing and comes equipped with a spring latch.  Geared Limit Switch Interrupts the control circuit to stop the motor and applies the motor brake when hook reaches its upper and/or lower limits of travel.  Fully adjustable in both upper and lower directions.  Includes reversing circuit to prevent hook overtravel in either direction. Optional Equipment: Chain Bags or Buckets Push-Button Pendant Stations Suspension Lug mounted, push trolley, hand geared trolley, and motorized trolley.
