Manual sliding gate design typically consists of a pair of upper and lower roller assemblies mounted to counter balance posts. These are of a heavier construction than normal fence posts as they support the dynamic load of the cantilevered gate assembly.

The longitudinal pipe members of the gate assembly ride in these rollers which serve both structural and guide functions. They are in constant contact with these rollers when the gate is either open or closed.

These components are subject to high dynamic forces and need regular inspections for alignment and lubrication. Failure or malfunction of these components can result in a dangerous system failure which could injure a pedestrian or vehicular user of the gate.

Some types of gate systems rely upon the compression of pinch rollers to limit gate travel or to provide positive mechanical stop functions. This type of system requires routine maintenance to ensure the compression of these pinch rollers is within acceptable limits. Over time, without proper inspection or maintenance, these positive mechanical stops can drift electronically and can allow the gate to travel past the desired stop and fall on a pedestrian or vehicle user that is unaware of the defective condition of the gate.

Other types of gate systems rely on a series of rails or tracks. These systems are often used in industrial and high usage applications where a large number of gates need to be moved. These track based systems use a fully welded Australian made RHS frame, back runner and support posts and are available in a range of powder coating colours. The runner rail is typically made from 2″ x 2″ square or 5″ x 2″ rectangle extruded aluminium tubing that serves both the structural and guide role of the gate assembly.
