Application
The LIFTMASTER LPK5 is built for intense conditions where speed of opening & reliability are a priority.  Suitable for both cantilevered and bottom track type gates on Industrial Sites, Apartments, Secured Estates, Commercial & High Rise building entries.

Toothed Racking
The custom made racking is designed to be quite but strong.  The high tensile plastic outside protects a steel core.  Featuring fixing lugs every 200mm this rack has proved to be highly successful.

Steel racking is available on commercial sites.

Construction
The gearbox is mounted on a 4mm thick galvanised mounting plate.  Easy installation of the mounting plate is achieved with the provision of four 13 x 30mm slots.

Motor & Gearbox
The 0.55Kw, inverter driven motor is built to withstand the harshest conditions, with an electric brake as standard for positive locking of the gate.  The hollow shaft gearbox enables slim-line construction of the gate motor, with a 36:4 ratio providing the torque required to operate gates up to 2 tonne.

Safety
A sensitive inbuilt adjustable clutch provides an excellent anti-crushing device, however, photoelectric cells and or inductive loop detectors are recommended.  Whilst the gate opens quickly, slow closing is provided to prevent accidents.  An isolation switch is provided to shutdown the power during maintenance.  For additional safety, when the motor is disengaged, an automatic override switch prevents the motor from running.

Speed
Up to 800mm per second is achievable with soft start, slow stop feature.  Different speeds are available for both opening & closing directions.

Disengagement
In power failure situations, by removing the secure cover, a lever is available for simple disconnection of the gearbox mechanism allowing the gate to be opened manually.

Limits
Are provided to signal the function of the speed control with a special tool provided for simple, accurate adjustments.  A maximum travel of 10 meters is available.  Two extra limits are available for accessories i.e. Traffic Lights, Ventilation Systems, Interlocking, etc.
