Motorized Sliding Gates
Motorized Sliding Gates
Types of Motorized Sliding Gate Systems ; MAdoors Motorized Sliding Gates would normally run back and forth on grooved or circular wheels along a level horizontal beam fitted with a channel. The motor will drive the gate back and forth using a rack and pinion mechanism on the gate, powered by a cog at low level on the gate motor. This configuration however does require that the ground is relatively level and that a steel beam can be sunk into the ground the full length of the gate in both the open and closed positions. Any sliding gate in such circumstances requires to slide at least its own width either side of the opening, also taking into account the width of the motor (usually around 300 mm).
An alternative method of operation is the Cantilever System. Here there is no sunken steel beam the full length of the gate plus itself again. Instead the entire gate is suspended on a relatively short cantilever system involving wheels set in a channel (rather like the wheels of a train carriage). The "overhang" of the gate beyond the opening is usually around 30% to 40% of the nominal gate width and the entire gate pivots on the cantilever wheels. It then operates by running back and forth on these cantilever wheels. The Sliding gate motor principle is the same (i.e. toothed rack and pinion), with the motor being located in roughly the same position as with a standard sliding gate system.

Motorized Sliding Gate Weight Factor ; Unlike swing gates where other factors dictate how efficiently the gates will operate, a critical factor in sliding gates is the weight of each gate leaf. The entire gate leaf, in this situation is both powered by and resting on the drive unit. Thus individual automatic motorized sliding gate systems are calibrated in terms of gate weight in relation to motor specification.
Method of Operation Due to the design and direction of automatic motorized sliding gates the "hydraulic vs. electromechanical" argument does not enter into the equation. Sliding gates by their very nature cannot be hydraulic in operation. They require to be able to engage or disengage when under, at or over recommended thrust levels, in order that the motor does not fail. This operates rather like a clutch in car, which engages to drive and disengages to idle.
