01Overview
About Telescopic Sliding Gates
A telescopic gate solves a specific site constraint: the opening is wide, but there is nowhere near enough clear boundary alongside it for a single sliding leaf to retract into. Two or three leaves run on parallel tracks and nest inside one another, so the retracted stack is a fraction of the open width.
Operating method
03Variants
Available configurations
The same product, built for a different job. Where a specification depends on opening dimensions, selected profile, operating duty or site conditions, the final configuration is confirmed during technical assessment.
Two-leaf nesting
The usual arrangement. Halves the required side-run compared with a single leaf of the same opening width.
Three-leaf nesting
For very wide openings on very short boundaries, at the cost of a more involved drive and guidance arrangement.

Dimensions5 fields
- Maximum clear opening
- Up to 18,000 mm
- Maximum leaf width
- Up to 9,000 mm per telescopic leaf
- Maximum leaf height
- Up to 2,500 mm
- Maximum leaf weight
- Up to 1,500 kg per leaf
- Side-run or swing room required
- Approximately 50–60% of the clear opening, depending on the telescopic configuration
A design envelope rather than a combination: no single telescopic configuration reaches the maximum opening, leaf size and weight at once.
With the operator, this is what sizes the drive.
Cycle performance3 fields
- Travel speed
- Up to 10 m/min
- Opening time for full travel
- Application dependent
- Rated daily cycles
- Up to 300 cycles/day
Set by the clear opening, the number of leaves, the leaf weight, the operator configuration and its acceleration and deceleration, so no single figure covers every installation.
Construction6 fields
- Frame section
- Heavy-duty MS structural steel section
- Infill
- MS, GI, SS or aluminium, and customised infill options
- Running gear
- Heavy-duty guide rollers and telescopic carriage system
- Ground arrangement
- Tracked telescopic or trackless configuration available, depending on the design
- Posts and foundations
- Site-specific structural design
- Finish and colour
- Powder coated, PU painted or hot-dip galvanized options
Wheels, rollers, cantilever carriage or hinges.
Tracked, trackless or cantilever.
Drive5 fields
- Operator type
- Rack-and-pinion geared operator
- Rated motor power
- 0.75–1.5 kW, depending on gate size, weight and number of leaves
- Supply voltage
- 230 V AC single phase, or 415 V AC three phase
- Duty rating
- Heavy-duty, intensive use
- Manual override
- Key-operated emergency manual release
Selected per gate rather than fixed across the range.
Control4 fields
- Control system
- Microprocessor-based electronic control panel
- Activation devices
- Remote control, push button, key switch, RFID or access control, and loop detector
- Travel limit setting
- Electronic or magnetic limit system, depending on the operator
- Interfaces
- Access control, traffic lights, interlocks, and external control systems
Access control, traffic lights, alarm panel, interlocks.
Safety6 fields
- Photocells
- Dual safety photocells with presence detection
- Safety edge
- Sensitive safety edge where required
- Obstruction detection
- Electronic obstruction detection with automatic stop and reverse
- Operating force limitation
- Designed and tested according to applicable powered-gate safety requirements

FAQ
Questions we are actually asked
- How much space is needed beside a sliding gate?
- A single leaf needs roughly its own width of clear boundary to retract into, plus the operator. Where that does not exist, a telescopic arrangement halves it and a swing or retractable gate may suit better.
- Tracked or cantilever?
- Cantilever where the driveway must stay clear for drainage, silt or heavy loading. Tracked where the approach is level and well drained and the leaf is long and heavy.
- What happens if the power fails?
- A key-operated manual release disengages the drive so the leaf can be moved by hand. Battery backup can be specified where the entrance must keep operating.
- How is the gate stopped from closing on a vehicle?
- Photocells across the opening, a safety edge on the leading edge, obstruction detection in the operator, and ground loops that confirm the vehicle has cleared before closing.
