Dayton 3KR11 Beam Clamp

The Dayton 3KR11 is a steel beam clamp rated for a 2000 lb working load limit. It fits flat beam flanges from 3 in to 8 5/8 in wide and up to 3/4 in thick. The jaw opening adjusts between 2 1/2 in and 10 1/4 in. A shaft attachment point allows vertical lifting with compatible rigging hardware.

Thermals Noise Power

This mechanical clamp has no moving parts, motor or electronics, so it produces no heat, noise or electrical draw during normal use. All load is transferred through the steel body and screw mechanism. Operation stays silent and thermally neutral regardless of duty cycle.

Upgrade Path

The clamp replaces chain slings or loose hooks when a secure, repeatable grip on a beam flange is required. The jump is worth it for rigging crews who need faster setup, consistent jaw alignment and a rated attachment point that meets ANSI/ASME B 30.20 without improvised rigging.

Questions about this item

How is the Dayton 3KR11 beam clamp installed on a flat beam, and what step is often missed?

Position the clamp over the beam flange with the shaft attachment on top, then tighten until the jaw opening grips between 2 1/2 in and 10 1/4 in; the step often missed is confirming the beam thickness does not exceed 3/4 in and the width stays within 3 in to 8 5/8 in before lifting.

What maintenance or replacement will the Dayton 3KR11 beam clamp need over time?

Inspect the steel body, jaw surfaces and shaft attachment regularly for wear, deformation or corrosion; replace the clamp if the jaw opening no longer holds within the 2 1/2 in to 10 1/4 in range or if any component shows cracks or excessive wear.

What limit appears first when the Dayton 3KR11 beam clamp is used continuously at its 2000 lb working load limit?

The working load limit of 2000 lb is the primary limit; sustained use at this rating requires strict adherence to ANSI/ASME B 30.20 inspection intervals to prevent fatigue or deformation of the steel clamp components.
