Low dock levelers are installed on top of existing low-height loading docks, typically raising the dock height by as much as 11 inches. Unlike standard loading dock levelers that are recessed into pits in the dock floor, low dock levelers mount directly onto the existing concrete surface, creating an elevated platform that brings the dock closer to standard trailer bed heights. These units function as both a height adjustment mechanism and a bridge between the dock and vehicle, accommodating the remaining height differences through their adjustable deck and lip extension.
Installation and Applications
Low dock levelers offer a cost-effective alternative to major dock reconstruction. They mount directly to the existing dock surface without requiring pit excavation, making installation faster and less disruptive to operations. These units are particularly valuable for:
- Older facility retrofits with non-standard dock heights
- Warehouses converting from rail to truck service.
- Distribution centers adapting to modern trailer heights.
- Can work in conjunction with wheel risers
- Facilities requiring temporary or seasonal dock height adjustments
Frequently Asked Questions
A low dock leveler mounts on top of an existing low dock to raise its height, while standard dock levelers are installed in recessed pits flush with the dock floor. Low dock levelers create a raised platform plus leveling capability, whereas standard pit levelers only provide height adjustment from the existing dock level.
According to OSHA regulations, all dock levelers must comply with safety standards, including:
• Run-off guards to prevent forklifts from driving off edges
• Smooth transition requirements to minimize “dock shock” and reduce workplace injuries
• Proper securing mechanisms to prevent movement during loading/unloading
• Compliance with ANSI MH30.1 and MH30.2 standards for dockboards and levelers
• Fall protection is required when the dock creates a drop of 4 feet or more
• Loading dock stairs – Not required, but allows workers to access docks safely.
Low dock levelers typically provide:
• Platform height increase: Up to 11 inches above existing dock
• Service range above platform: 5-12 inches upward adjustment
• Service range below platform: 5-12 inches downward adjustment
ª Total effective range: Can accommodate trailer beds from significantly below to above the original dock height
Yes, low dock levelers are designed for surface mounting without pit excavation. Installation involves anchoring the unit to the existing concrete dock surface, requiring minimal construction compared to pit-style levelers . This makes them ideal for retrofitting older facilities or temporary installations.
