|Heavy Industrial-Duty Gear-Reduced Hoist Operator –|
Model GH is a heavy industrial-duty gear-reduced hoist operator. It features a removable hinged electrical box cover and is easily field-converted in seconds for a left or right-handed drive and hoist.
LOGIC 4.0 TECHNOLOGY (L4)
Reliability & Programming Simplicity
Available Plug-in Options for Logic 4.0 (L4)
TLS1CARD: Provides seven field-selectable modifications, including six door traffic control options. Combines with Logic 4.0’s standard Timer-to-Close feature to offer timed, sequenced activation of warning lights, sounders, and other devices (sold separately) that can be operated via dry contact closure.
CPS3 or CPS3-N4 Option: Enables the addition of a second set of photo-eyes.
Mechanical Reversing Contactor Circuit (M): (115V, 208/230V, 460V, 575V, 24V NEC Class 2 Circuit with 40VA transformer) Industrial linear contactor provides significantly longer control runs than conventional contactors.
Auxiliary Chain Hoist: Reduced drive chain hoist with electrically interlocked floor level disconnect for manual operation. Hoist wheel is easily moved to right- or left-hand side of unit, eliminating the need to order left- or right-hand mounting.
Drive Reduction: 45:1 using heavy-duty gears running in oil bath. Cast iron housing. Special “all-climate” synthetic gear oil for greater low-temperature performance.
Emergency Disconnect: Spring-loaded for emergency manual operation.
Wiring Type: All operators are factory preset to C2 wiring providing momentary contact to open and stop, with constant contact to close; D1 and E2 wiring are also available. Momentary contact to close (B2 wiring), T, TS, and FSTS wiring can be activated with the use of CPS-RPEN4, CPS-U, CPS-UN4, or CPS-EI safety edge interface. The operator is pre-wired to accept a sensing device, photoelectric sensors, radio controls and most types of access control equipment.
External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators.
Bearings: Sealed roller bearings in gear reducer.
Brake: Solenoid-actuated brake is standard to prevent coasting of door.
Construction: NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with durable powdercoat finish, all reduction sprockets drilled and pinned to shafts.
Push Button Station: 3-button station comes standard and has OPEN/CLOSE/STOP functionality.
Warranty: 2-year warranty.
Ancillary Entrapment Protection: (optional) LiftMaster Retro-Reflective Commercial Protector System® photo sensors, 2-wire non-monitored sensing edges and pneumatic sensing edges are considered secondary entrapment protection and may be used to supplement primary entrapment protction or basic constant-pressure-to-close.
