Caldwell Launches Dura-Mod Modular Spreader Beams

Feb. 3, 2020 —The Caldwell Group Inc., Rockford, Illinois, has launched the Dura-Mod modular spreader beam, a versatile, lightweight alternative to fixed- and multiple-point below-the-hook solutions of up to 170-ton capacity.

Well-suited to many markets, including oil and gas, heavy engineering, and crane and equipment rental, the Dura-Mod spreader is a new rigging concept for Caldwell. It complements the company’s existing family of fixed beams, adjustable beams, beam end fittings, and ‘build your own’ spreaders.

Dura-Mod was unveiled at the Associated Wire Rope Fabricators’ Product Information Exhibition (PIE) in Cleveland, last spring. Based on response from dealers and users, Caldwell has now added capacities to the range, and it is developing models with even higher capacities of 250 U.S. tons or more.

“Each system will consist of a pair of end fittings and drop links, plus two upper and lower shackles to make the shortest possible configuration,” said Malcolm Peacock, business development specialist at Caldwell. “From there, it is a simple case of combining intermediate spreader sections to achieve the required span. The longest component is only 20’.”

Peacock said that a square or rectangular spreader frame can be made easily by removing the end fittings and adding corner sections to the same struts. “We provide a full assembly procedure on our data sheets, along with details of fasteners and torque values,” said Peacock. “We can also manufacture any custom or special parts to order. That enables us and our distributors to provide flexible service.”

Caldwell is keeping a large inventory so it can respond quickly to customers’ needs. Also, the company communicates with potential stock-holding distributors so they can supply clients on a quick-ship basis. Peacock said the long-term goal is to have complete U.S. coverage of Dura-Mod stock.

Darrin Noe, director of sales at Caldwell, said: “Upon the concept’s launch, we received an overwhelming response. Everyone we met was excited about having access to the product. We have since been working hard to get it finalized and ready for the U.S. market in particular, and we were ready to stage the full launch at the end of January 2020.”

Noe noted that the Dura-Mod’s versatile design lets Caldwell and its distributors hold ample inventory and provide a certified spreader from stock.

All Dura-Mod spreaders use standard shackles available from all major manufacturers. Caldwell specifies top sling lengths, and the load determines the lower rigging.

Box beams and spreader frames can be used for four-point lifts where there may be headroom restrictions. Similar to regular modular spreaders, the frames are easy to store and transport, and they can be broken down and reassembled for multiple lifting applications.

Noe said: “Malcolm’s addition is huge for Caldwell as the [Dura-Mod] program advances. Modular beams are his strong suit, and we plan to follow his lead on how we go to market.”

All Dura-Mod spreaders conform to ASME B30.20 and BTH-1 Design Category B, Class 0. Each modular system is manufactured in house and is provided with a “Made in the USA” badge.

Notably, Caldwell said Dura-Mod can be used in conjunction with other manufacturers’ products if all components are certified and conform to relevant standards.
