Construction

Fully welded RHS steel section is used in the manufacture of the gate frame, support tower and back runner track. All fabricated steel is hot dip galvanised for total protection and maximum life time. The design allows for single leaf spans of up to nine (9) metres.

Technology

The standard speed drive system incorporates an STA 210 Magnetic torque drive which operates from a single phase 240 volt power supply. This is mounted onto a pivoted sub assembly with in-built shock absorber.

A 24v DC brake is incorporated with the motor and is used to positively lock and retain the fully open or closed positions in a fail safe condition. The output shaft of the motor drive attaches to a spur gear which engages with rack sections on the upper rail of the gate.

Position control is achieved with a proximity sensor identifying striker blocks attached to the gate. The high speed drive system incorporates a 3 phase induction motor/gear box. It operates from a single phase 240 volt power supply but derives 3 phase power from an inverter in the controller.

This is mounted onto a pivoted sub assembly with in-built shock absorber. A 24v DC brake is incorporated with the motor and is used to positively lock and retain the fully open or closed positions in a fail secure condition.

Position feed back is provided by a proximity switch sensor identifying striker blocks attached to the gate. These signals are used to control ramp up, ramp down, high speed, low speed and end position conditions.
