Tandemloc's AQ25A Beam Clamps have two principal uses. The first is an ASME B30.20 below the hook lifting device. These clamps can also be used as a structural fixed point to hang manual and powered hoists as described in ASME B30.16.
These Tandemloc I-Beam clamps are designed to the most severe design requirements: ASME B30.20 and its design document BTH-1. By doing this we provide superior steel beam lifting equipment in both function and safety.
As an ASME B30.20 Lifting Device, the Tandemloc Beam Clamp is suitable for lifting and moving I-shaped structural members and fabrications. These include W-Shapes, M-Shapes, HP-Shapes, and S-Shapes. All beams must be within the flange range and WLL of the selected size of the selected Tandemloc I-Beam clamp.
Using a Tandemloc I-Beam clamp as a temporary attachment point for manual or powered hook-suspended hoists is limited to vertical (90°) lifting. Each Tandemloc Beam Clamp includes a mechanical position lock for added safety when in the closed position.
Each clamp is proof-tested up to 125% of the WLL per ASME B30.20 specifications, so you know that you'll have no issues lifting under that WLL. They also range in minimum and maximum flange width from 3.75 to 9 inches to 4.5 to 12.5 inches.
We have four sizes that are in stock and two heavier capacity sizes available for order and delivery within a reasonable time frame.
