2.02 Manufactured Unit
- Vertical Pivot Gate System: Ideal Mfg., Inc./TILT-A-WAY DCM.
- Gear Motor Unit: 1/2 HP 24V DC TENV motor, 1800 RPM, full load amps 13.5, continuous duty, right angle.
- Gear motor will be all as one unit with lubricating fluid.
- The gear motor will be designed to keep the gate locked in the closed position, keeping any person from lifting the gate open when it is in the closed position.
- Pedestal Frame: Welded construction with removable outer skin of cross break 16 gauge aluminum panels.
- Inspection Door Hardware: Stainless steel continuous hinges and heavy-duty lockable pull down catches to hold inspection door shut.
- Power: 115 Volt AC 24 Volt DC battery back up [24 Volt DC gear motor and control board] [115 Volt AC for battery charger and optional accessories]. Battery supplied by installer, or owner. Total gate system requires 20-amp minimum service, with no more than 3% drop in voltage, while gate is in operation. (FOR WIRE SIZE: CONSULT LOCAL ELECTRICAL CODE.)
- Soft stop on both ends.
- Gear Motor will move the barrier from the closed position to open position, and open position to closed position in approximately 10 to 12 seconds each direction.
- Gate actuating System: Number 40 Roller Chain and Sprockets.
- Hardened teeth sprocket, adjustable magnetic switch stops on each end of travel.
- Gear Motor Fluid: Manufacturer’s standard, factory checked, filled, and tested.
- Balance System: System designed to allow barrier to be hand raised and to be hand lowered with 12 to 15 pounds of pressure, consisting of manufacturer’s standard cables, sheaves, sealed cam yoke roller bearings, and tension springs pulled in a straight line.
- Safety Control Switch: Provide built-in safety control switch capable of stopping barrier in any position should balance system fail.
- Testing: Factory test and adjust balance system to ensure gate may be manually raised and lowered with specified pressure.
- Signage: Signage to be added to the gate barrier must be declared at the time of order so the manufacturer can add the signs on the barrier, to ensure Ideal Mfg. balances the barrier correctly at the time of manufacturing.
- Electrical System: Oversized rain tight enclosure housing electrical components except limit switches, safety switches, and motor.
- Wire: Oil and gasoline resistant.
- Overload Protection: 20-amp fuse to protect motor.
