Caldwell Dura-Mod 50 Metric Ton Modular Spreader Beam System

Caldwell Dura-Mod® DM50 Modular Spreader Beam System

The Caldwell Dura-Mod® Model DM50 is a 50 metric ton modular spreader beam system designed to provide maximum flexibility for lifting heavy and oversized loads. Its innovative bolt-together design allows users to configure beam spans from 3 feet to 41 feet using interchangeable spreader sections, end fittings, and drop links. Instead of purchasing multiple fixed-length spreader beams, contractors and industrial lifting professionals can build the exact beam configuration required for each lift using a common set of components.

Designed for demanding industrial environments, the DM50 is manufactured to meet ASME B30.20 and ASME BTH-1 Design Category B, Service Class 0 requirements. The modular system minimizes storage space, reduces transportation costs, and provides outstanding versatility for steel fabrication, precast concrete, energy, shipbuilding, heavy construction, manufacturing, and industrial maintenance applications.

Advantages Over Fixed-Length Spreader Beams

Frequently Asked Questions

What is the Caldwell DM50 used for?

The DM50 is a modular spreader beam system used to safely lift heavy loads while maintaining proper sling angles and reducing compressive forces on the load.

What is the lifting capacity of the DM50?

The system is rated for up to 50 metric tons, with allowable capacity depending on beam span and sling angle. Always reference the official Capacity vs. Span chart before lifting.

How many beam lengths can be built?

The modular system can be configured in spans from 3 feet to 41 feet using interchangeable spreader sections.

Can the bolt kits be reused?

Yes. Caldwell specifies that the bolts, nuts, and washers may be reused when anti-seize thread coating is applied during assembly.

Are shackles included?

No. Shackles and slings are not included and must be selected separately as part of the lifting plan.

Which slings can be used?

The DM50 can be used with properly selected synthetic web slings, wire rope slings, or chain slings as specified in the lift plan.

Why choose a modular spreader beam?

A modular system reduces equipment costs, minimizes storage space, simplifies transportation, and provides the flexibility to configure numerous beam lengths from one reusable set of components.
