Design
The Australian made Liftmaster 930 barrier gate housing is constructed of 3mm powder coated aluminium.  All seams are welded and the interior framing is a 5mm aluminium welded angle.

The reinforced door provides added strength to the cabinet, has 6 louvers for ventilation and is secured by a vandal resistant flush mounted keyed lock. 

The gate housing door is mounted to the rear of the cabinet to enable servicing of the unit away from the vehicle path, allowing easy access and safety.  For limited rear space situations the door can be mounted to the front of the cabinet.

Available in either left or right hand mounting, for the correct alignment of dual gates.

Motor Drive
The gate arm is driven by a 1/3 HP heavy duty, high output torque 240v single phase, instant reverse motor with a duty cycle exceeding 800 operations per hour.  The motor is connected by two V belts to a heavy duty single reduction gear box.  The gear box transmits power to the gate arm drive shaft through a harmonic acting crank and connecting rod with adjustable limit switches & cams regulating the gate arm travel.

The crank, connecting rod and main shaft are manufactured from heavy duty rolled steel, cad plated to deter rust and corrosion

Finish
The standard Colour is powder coated white, but other colours are available on request.

Boom Arm
The boom arm is available in 3m & 4m lengths and is constructed of 60mm round powder coated aluminium with reflective film. The arm is equipped with an internal sleeve to ensure a clean break and easy reinstallation if the arm is hit with great force.
