We offer two types of sliding gates: firstly the Tracked Sliding Gate which utilises a ground track laid across the opening, for the gates wheels to run along. The second is the Cantilever Sliding Gate which does not have a ground track and travels above ground like a piston effect being pushed out from its mounting point, with a counter balance on the one side.
We also have a range of Bi-Parting Telescopic Sliding Gates, be it either Tracked Telescopic Sliding Gates or Cantilever Telescopic Sliding Gates, with various finishes, style and colour with bespoke options available. bi-parting Most styles are available in our sliding gate range
Benefits of Sliding Gates
Sliding Gate Systems are the most secure automatic gate systems around, as due to their operation and positioning, when closed they are almost impossible to open. They are held in place by the tracking system, drive motor, and other features of the installation, such that they cannot be wedged sideways except by very unusual and extreme force.
Types of Sliding Gate Systems
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 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.
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 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 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.
Size and Rating of Automatic Sliding Gate Motors
Most domestic and light commercial applications can operate on the same motor supporting gate leaf weights of around 300 Kg to 800 Kg. Heavier sliding gate leaves for commercial/industrial applications might require motors which will drive weights in the region 1000 Kg to 2000 Kg. Typically of the above motors would operate from 240V, single-phase AC supply, available in most homes and businesses.
Exceptionally heavy industrial gates, such as in dockyards and perhaps spanning in excess of 20 metres, might require motors capable of driving gates in the region of 2000Kg to 4000Kg, these heavy-duty motors would usually require 415V, three-phase AC supply, normally available in industrial premises.
This particular gate is constructed to appear like a traditional pair of swinging gates, in fact it is a one piece sliding cantilever gate, full automatic.
The Automatic Cantilever Sliding Gate is suspended over the gate opening by a set of high quality sealed bearing cantilever rollers mounted onto steel posts. A cantilever gate does not have a ground track and is ideally suited to uneven ground. The Back-frame on these gates is 60% to 70% of the opening width so they require more side room than a ground track installation.
With this particular gate, the track is concreted into the ground providing a smooth run.
This large commercial cantilever gate is 12m long x 2m high, constructed using 100mm x 100mm RHS frame with 50mm x 50mm RHS vertical bars. This construction provides a strong gate that slides with ease powered by a heavy duty sliding gate motor.
This particular gate is constructed from palisade style fencing with an overall steel frame construction, with fully automated cantilever operating system, without the need to any floor tracks or raised sliding rails. Therefore providing a clear unobtrusive opening.
To achieve the maximum clear opening where the backrun is very restricted, the telescopic gate is ideal. Telescopic tracked gates can be made with up to five sections, and can reduce the backrun required by 75 %, compared to a single leaf gate. Our special static drive system allows all the leaves to move simultaneously, alternatively we can utilize a special moving drive system that is incorporated into the leading gate leaf, and driving the rear wheel.
The span can cover an are of upto 25mtrs.
EDS can maintain any type of existing system, providing on-site and workshop repairs to any make of systems. With a large stockholding of spare parts we can turn around repairs rapidly.
Regular maintenance is fundamental to ensure your systems operate as effectively as when they were first installed, we are able to provide competitive quotation for maintenance of new and any type of existing system.
