Air-Assisted Lift Gate

An all-welded steel gate that pivots across the dock opening when no trailer is docked, standing 42″ high so it reads as a barrier rather than a trip rail. It mounts over a 6″ × 42″ bollard, which means the bollard takes any impact instead of the gate hinge. Supplied in 5 ft to 14 ft widths in 1 ft increments, single or paired for wide openings.

• Height: 42″ (OSHA guardrail height)
• Widths: 5 ft to 14 ft in 1 ft increments
• Construction: All-welded steel
• Mounting: Over a 6″ × 42″ bollard

The heaviest barrier in the dock range, rated by the manufacturer at 30,000 lbs at 4 mph — an order of magnitude above interior guardrail, because a loaded truck reversing at a dock edge carries far more energy than an aisle strike. Built on 5″ steel posts with 12″ × 12″ × 5/8″ offset base plates and 1″ pins, with a sliding locking plate and no pinch points. Clearances of 8, 10 and 12 ft.

• Impact rating: 30,000 lbs at 4 mph (manufacturer-stated)
• Height: 42″
• Posts: 5″ steel on 12″ × 12″ × 5/8″ offset base plates
• Clearances: 8 ft · 10 ft · 12 ft

A retractable industrial fabric barrier that pulls across a dock or door opening at about 3 lbs of effort, so it actually gets used on every cycle rather than being left open. At 42″ high it provides a visible stop for pedestrians and pallet trucks while still letting air move through, which keeps a ventilated dock ventilated and blocks birds, insects and blown debris. Widths from 8 ft to 20 ft.

• Height: 42″
• Pull force: ~3 lbs
• Widths: 8 ft · 9–10 ft · 11–12 ft · 13–16 ft · 17–20 ft
• Airflow: Permeable — blocks debris, insects and birds
