2907 SILVER SERVICE® lift curtain machine. 1/2 H.P.
Lift machine designed for operation of motorized Austrian, Contour, Waterfall, and Gym Divider curtains and rated to lift a 100 pound load when connected to a standard cable type lift system. Machine includes 6" diameter x 14" wide helical grooved drum grooved for 3/16" wire center cable, right-angle gear reducer, integral limit switches, outboard support bearing, magnetic-control-system, and can be operated from an unlimited number of remote control stations (push-button type).
This unit is capable of lifting, without the need of counterweights, substantial loads in accordance with established maximum weights. Each machine is equipped with a built-in magnetic brake to facilitate precise positioning. Complete with magnetic friction brakes, Stop, Start and Reverse control plus direct drive, makes this machine completely versatile.
Maximum cable travel is 70'. Cable speed is 54 fpm fixed.
Guard (ME-1) not shown. Required for ETL compliance.
These machines are not to be used for the lifting, supporting, or transporting of people. These machines should not be used to move objects over areas where people are present unless suitable safety devices are installed.
GROOVED CABLE DRUM
Assures positive drive without cable slippage. Constructed of powder coated steel 6" diameter x 14" long. Coated wire-center cable must be used. Provides up to 70' of cable travel.
MAGNETIC FRICTION BRAKE
Furnished as either part of the motor (brakemotor) or inline with the motor and gear reduction unit. Helps to provide precise stopping in both directions.
CONTROL STATIONS
Three-button type. Provide Stop\Start\Reverse control from any point of travel. No limit to the number of remote control stations that can be used. Two supplied with each machine, one fixed to the machine and one for use as a remote control station.
MAGNETIC CONTACTOR
Provides Start/Stop/Reverse control for the machine. Compatible with most automation systems. LVCS Low Voltage Control System, 24 VAC standard.
ROTARY LIMIT SWITCH
Allows for user defined pre-set stops for the "Full Raise" and "Full Lower" positions.
DISCONNECT SWITCH
Toggle switch which removes power to machine’s internal circuitry.
OVERLOAD PROTECTIVE BREAKER
Automatic type helps protect machine, track and curtain against effects of accidental overload. Must be manually reset.
THERMAL OVERLOAD
Built into some motors to help prevent possible damage to the motor due to overheating (furnished on some single phase motors only).
SAFETY RELAY
Prevents single phase motor from continuing to run in the same direction when the push-buttons are pressed at the same instant as the limit switch is tripped.
