Telescopic sliding gate hardware

• Cable and Pulley System: This is a common method. When the primary gate leaf (the one directly driven by a motor or moved manually) begins to open, a series of cables and pulleys pull the secondary and tertiary leaves along parallel tracks. The cables are strategically routed so that each subsequent leaf moves at a faster rate, allowing them to stack neatly behind the primary leaf when fully open.
• Geared Track System: Some advanced systems use a geared track where a pinion on one gate leaf engages with a rack on the next, driving it along.

1. Gate Leaves: These are the individual sections of the gate. They are designed to slide smoothly past each other.
2. Tracks:
   • Ground Tracks: Parallel tracks are installed on the ground for each gate leaf to slide on.
   • Upper Guide Profile/Track: A top guide system is crucial for stability and smooth movement, preventing the gate leaves from wobbling or derailing.
3. Wheels: Each gate leaf has wheels (often V-groove or round groove) that run along the ground tracks. These are typically heavy-duty to support the weight of the gate.
4. Pulley System/Transmission Unit: This is the heart of the telescopic mechanism. It includes:
   • Pulleys: Used to route and guide the steel cables.
   • Steel Cables: Connect the gate leaves, ensuring synchronized movement.
   • Cable Covers/Casings: Protect the cables and provide a neat appearance.
   • Adjustable Pulley Systems/Tensioners: Allow for precise adjustment of cable tension to ensure smooth operation and prevent stretching over time.
   • Connection Brackets/Couplers: Connect the cables to the gate leaves.
5. Guide Brackets/Rollers: These are installed at the top of the gate or on a support post to keep the gate leaves aligned and stable as they move. They often feature nylon rollers to reduce friction and noise.
6. Gate Stops and Receivers: To define the fully open and closed positions and secure the gate when closed.
7. Gear Rack (for automated gates): If the gate is automated, a gear rack will be installed on the primary gate leaf, which engages with a pinion on the gate motor.
8. Gate Motor (for automated systems): A powerful sliding gate motor is required, often a low-voltage DC motor with advanced electronics to handle the varying speeds and loads of the multiple leaves. A speed reduction gearbox may also be incorporated for safety.

• Space-Saving: The primary advantage, as they require significantly less run-off space than single-leaf sliding gates.
• Wider Opening: Allows for a wider clear opening in situations where space limitations would otherwise restrict it.
• Faster Operation: Can often open and close more quickly than a single, very large sliding gate.
• Aesthetics: Can be a more visually appealing solution for properties with limited space.

• Complexity: More complex to design and install than a standard sliding gate due to the synchronized movement.
• Maintenance: Requires regular lubrication and checking of the cable and pulley system to ensure smooth and reliable operation.
• Weight Distribution: Proper engineering is crucial to distribute the weight of multiple gate leaves evenly and ensure stability.
