Caldwell Model BC Beam Clamp 1-Ton Capacity
Caldwell Model BC Beam Clamp — Reliable 1-Ton Vertical Lifting for Structural Steel
The Caldwell Model BC Beam Clamp (part number 55-1) is a purpose-built construction lifting device designed for attaching to structural steel beams and flanges ranging from 1 to 4 inches wide. Rated at a 1-ton (2,000 lb) load capacity, it is engineered for vertical lifting only and complies fully with ASME standards, making it a code-compliant solution for contractors and rigging professionals. The clamp accommodates a 13/16-inch diameter hole sized for shackles rated up to 3-1/4 tons, providing a secure connection point to hoists and rigging hardware. It is suited for steel erection, structural positioning, and overhead rigging applications across commercial and industrial construction sites.
Unlike complex multi-function lifting attachments, the Model BC is built around simplicity, reliability, and low cost of ownership. Its lightweight yet high-strength steel construction reduces operator fatigue during repeated use while delivering consistent, dependable performance without the maintenance demands of more complex rigging systems. For contractors who need a straightforward, ASME-compliant beam clamp that ships ready to work, the Model BC delivers without compromise.
Key Features & Benefits
1-Ton Rated Load Capacity
The Model BC is rated for 1 ton (2,000 lbs) of vertical load, providing a clearly defined working load limit that helps crews maintain compliance with lift plans and safety protocols. Having a defined capacity reduces guesswork and supports proper rigging documentation on regulated job sites.
ASME Standards Compliance
Full compliance with ASME standards means this clamp meets the engineering and safety requirements expected on commercial and industrial construction projects. For contractors working under third-party inspection or general contractor oversight, ASME-rated hardware reduces liability and simplifies equipment approval processes.
Lightweight and Portable Design
Weighing only 10 lbs, the Model BC is easy to transport, position, and attach by a single worker without additional handling equipment. Portability matters on active steel erection sites where rigging hardware needs to be repositioned frequently throughout the work day.
High-Strength Steel Construction
Despite its compact size and low weight, the clamp is manufactured from high-strength steel to handle repetitive load cycles without deformation or fatigue failure. This durability translates directly into a longer service life and reduced replacement cost over the life of a project or fleet.
Economical and Convenient
The Model BC is designed to deliver essential beam-clamping function at a competitive price point, making it practical to stock multiple units for simultaneous use with spreader beams or across multiple lift points. Its no-frills design also means fewer components to inspect, adjust, or replace between lifts.
13/16" Shackle-Compatible Hole
The integrated 13/16-inch diameter lifting hole accepts standard shackles rated up to 3-1/4 tons, giving crews flexibility to connect to a wide range of rigging hardware already on site. This eliminates the need for custom adapters or special fittings, saving time during rigging setup.
Common Applications
Lifting and Positioning Structural Beams
The primary application for the Model BC is attaching to I-beams and wide-flange sections during steel erection, allowing cranes or hoists to lift and place structural members with precision.
Paired Use with Spreader Beams
Two Model BC clamps used in tandem with a spreader beam allow balanced, two-point lifts of long structural members, reducing bending stress on the load and improving lift stability.
Hanging Hoists from Overhead Structures
The clamp can be attached to an existing overhead load-bearing beam to create a temporary hoist attachment point, enabling chain hoists or come-alongs to be suspended without permanent anchorage hardware.
Temporary Rigging Anchor Points
On sites where permanent rigging attachments are not yet installed, the Model BC provides a quick-connect rigging anchor on any accessible beam flange within the rated flange width range.
Steel Fabrication and Erection Support
Fabricators and ironworkers use beam clamps like the Model BC to maneuver and align steel members during fit-up and welding operations where controlled vertical movement is required.
Material Handling in Industrial Facilities
In warehouses, manufacturing plants, and maintenance facilities, the Model BC can be clamped to overhead structural steel to temporarily hang a hoist for equipment installation, removal, or repositioning tasks.

- Wide-flange (W-shape) steel sections

Frequently Asked Questions
Q: Is a shackle included with the Model BC Beam Clamp?
A: No. The Model BC does not include a shackle. The 13/16-inch diameter lifting hole is designed to accept a separately sourced shackle rated for up to 3-1/4 tons.
Q: Can the Model BC be used for horizontal or angular lifting?
A: No. The Model BC is rated for vertical lifting only. Using it at an angle would exceed its design parameters and create unsafe loading conditions not covered by its ASME rating.
Q: What flange width range does this clamp accommodate?
A: The Model BC fits beam flanges from a minimum of 1 inch to a maximum of 4 inches in width, covering a broad range of standard structural steel sections.
Q: Can two Model BC clamps be used together with a spreader beam?
A: Yes. The Model BC is specifically listed as suitable for use in pairs with a spreader beam, enabling balanced two-point lifts of long structural members. Each clamp still carries its individual 1-ton rated capacity.
Q: Is the Model BC compliant for use on regulated commercial construction sites?
A: Yes. The Model BC complies with ASME standards, which are the industry benchmark for lifting device compliance on commercial and industrial construction projects in North America.
Q: What is the weight of the Model BC and why does it matter for field use?
A: The Model BC weighs 10 lbs, making it light enough for a single worker to carry, position, and attach to a beam without assistance. This reduces setup time and operator fatigue during high-frequency use.
