YS Series Height Limiter
A system that limits vehicle entry height to protect overhead structures, installations and door systems from vehicle impact.
Clear height warning
High-visibility striping and signage give the driver early warning.
Flexible/sprung structure option
Can return to its original shape after light contact without permanent damage.
High visibility
Standard safety orange/yellow for visibility even in low light.
Easy adjustability
Clearance height can be adjusted to match site requirements.
Applications
Where it's used
Indoor parking entrances
Passages above loading docks
Warehouse door entrances
Tunnel and underpass entrances
Height restrictions over service roads
Building entrance/exit doors
Engineering Approach
Why it's designed this way
01 — Risk
Most damage lands on the structure, not the vehicle
Most damage at indoor parking entrances, loading dock passages and tunnel entrances happens because a driver forgets to check their vehicle's height against the clearance — and the overhead structure, installation or door system takes the hit directly.
02 — Measurement precision
The right height is a value measured on site
The limiter's height is calculated from the safe tolerance for the tallest vehicle expected to pass through. That calculation is only accurate once it's confirmed by an on-site measurement — installing to an estimated value may not fully cover the risk.
03 — Design logic
A flexible/sprung structure limits damage from accidental contact
The chance of a driver still making contact is never zero. A flexible or sprung structure lets both the vehicle and the system come away from that contact without permanent damage.
04 — Our approach
A passage-specific decision, not a standard part
Clearance height and opening width are finalized through our same 5-step engineering process (design, calculation, procurement, installation, commissioning) following an on-site measurement.
