Overview
The KUPO RBC-3BK is a RIGPRO adjustable beam clamp rated for 3,000 kg working load limit, designed to create a temporary or permanent rigging point on beams, pipes, and structural bars. It installs by hand, needs no specialty tooling, and uses an integrated suspension bar to keep the hoist hook close to the structure for better headroom.
Why It Matters
RBC-3BK is the largest clamp in this group, built for heavier hoist points and wider structural members. The 80 - 320 mm adjustment range gives it more reach than the smaller 1-ton and 2-ton versions.
Key Features
- 3,000 kg Working Load Limit (WLL) supports the selected rigging point capacity.
- 80 - 320 mm beam width range covers a practical range of beam and flange sizes.
- 4:1 design factor for vertical lifting gives the clamp a defined rigging margin.
- Each clamp is proof tested at 150 % of rated load and supplied serialized with test certificate and manual.
Applications
Use for chain hoist suspension, pulley blocks, static loads, temporary rigging points, venue beams, touring installs, theatre grids, and stage structures where the structural engineer and rigging plan approve the pickup.
Compatibility
Use on appropriate beams, pipes, and structural bars within the listed beam width range. Suitability must be confirmed against the structure, load path, and rigging plan.
Frequently Asked Questions
Do I need tools to install this beam clamp
The source describes installation as hand-tightened with no tools required.
Why does the suspension bar matter
The built-in suspension bar keeps the hoist hook close to the structure, which helps preserve headroom under low ceilings.
Can I use it on any beam
No. The beam or structural bar must fit the listed beam width range and be approved for the intended load by the rigging plan and responsible engineer.
