Calculating the Rollback Zone for Cantilever Hanging Gates: Engineering Analysis and Space Standards

When designing entrance groups, the engineers and customers of the KSV Systems online store primarily rely on the "actual construction footprint" parameter. The choice of gate type directly depends on the available space along the fence. If the rollback zone is limited, it imposes strict constraints on the design, but KSV always has ready-made engineering solutions for tasks of any complexity in its arsenal.

Technical Regulations of the Standard Scheme

From a mechanical perspective, hanging gates are the most stable construction, as the main load is distributed across the upper guide rail. However, to ensure the tightness of the opening and eliminate "light gaps," the frame must be wider than the driveway itself.

A1 — entrance width (clear opening) | A2 — total frame length | A3 — required rollback zone

Basic Calculation Formula

For a standard single-leaf system, the calculation is performed using the following algorithm:

Space Optimization: Telescopic Systems

If an engineering audit of the site shows that the A3 zone is critically small, we recommend using telescopic hanging gates. In such a system, the leaf consists of several sections that overlap each other when opening.
