Dock Bridge Specification

The Dock Bridge is designed to accommodate a maximum of five inches above and below the dock, providing 18.5% grade down and 20% grade up. This is acceptable for most gas forklifts but is not suitable for pallet trucks or electric forklifts.

Pallet trucks and electric forklifts can be used with trailers 3 inches above and three inches below dock level. Dock boards or other equipment may be needed to accommodate a greater service range for pallet jacks and electric forklifts (This is due to limited clearance and grade this type of equipment operates at)

Torsion Spring Assisted Action

Raise and lower the ramp with less than 50 lbs. of force! The dock bridges torsion spring assembly takes the work out of raising and lowering the lip making it easy for most your personnel.

Operating Range

The standard Dock Bridge is designed for operation ±5" above and below dock level for gas forklifts or ±3” for all other equipment types.

Our Low Dock Solution

For loading docks too low for the standard working range we also offer ramps designed to be mounted to the floor of your loading dock opening. In function they'll effectively raise the level of your dock to where a dock bridge may be mounted at a height suitable to your freight needs.


Width Selection

Measure your door opening width. Most 8-foot doors use the 72" deck (102" overall). Here's the full lineup:

  • 66" deck / 96" overall - Standard 8' doors
  • 72" deck / 102" overall - Most common size
  • 78" deck / 108" overall - Wider openings
  • 84" deck / 114" overall - Extra-wide doors

Sizing: What Capacity Do You Need?

Add up your forklift weight + your heaviest load, then add 25% as a buffer. Round up to the next capacity.

Example: 6,000 lb lift + 4,000 lb load = 10,000 lbs × 1.25 = 12,500 lbs → get the 20K model

Capacity Typical Use
20,000 lb Light duty (smaller forklifts, lighter loads)
25,000 lb Standard ops—most common choice
30,000 lb Heavy-duty applications
35,000 lb Very heavy equipment/loads
40,000 lb Maximum capacity available

Maintenance

Keep it simple: clean and lube every 90 days. Hit the grease fittings on the hinge, check the springs and bumpers for wear.

Spring adjustment: Units ship without spring tension. After install, raise the plate fully, loosen the two set screws, rotate the square tubing about 1/4 turn toward you, retighten. Test and repeat if needed.

FAQ

What is the service range of a Dock Leveler?
All edge of dock Bridges offer a service range of 5" above and below for gas forklifts or 3" above and below for all other types of equipment. For greater heights above dock level we offer an alternate edge of dock leveler model with a ramp called the low dock leveler, to learn more about this option give us a call at 1800-741-1258.


Are bumpers included?
Yes Bumpers are included with the assembly.


Does installation require welding?
Yes, Loading dock bridge installation requires welding to either an embedded C channel or an approach plate mounted to the dock floor. The exception to this rule are low dock levelers which come fully welded, ready to be placed on the dock.


How do I get it into the truck?
Position the bridge onto the trailer by pulling the handle back towards the floor with approximately 45 lbs. of force. Once the handle is near the floor the handle will be lifted back towards the truck, where the lip will now glide forward on the the cantilevered lip catch that was set in place when the lip was raised. To cycle the leveler closed simply pull the handle back part way and release towards the truck.
