Caldwell launches two new products

11 February 2020


Rockford, Illinois-based The Caldwell Group has launched the Dura-Mod modular spreader beam and a vertical clamp.

Dura-Mod is a versatile, lightweight alternative to fixed and multiple point below-the-hook solutions up to 170t capacity. It was first unveiled at the Associated Wire Rope Fabricators Product Information Exhibition in Cleveland, Ohio last spring, but based on the response from dealers and end users alike, additional capacities have been added to the range and plans are already afoot to raise the capacity to 250t—and beyond.

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

“If a square or rectangular spreader frame is required you simply need to remove the end fittings and add corner sections—the struts are the same. We provide a full assembly procedure on our data sheets along with details of fasteners and torque values. We can also manufacture any custom or special parts to order.”

The other new product is the vertical and turning clamp designed for lifting and turning single curved plate or pipe from horizontal to vertical and vice versa.

The model TLC (turning, locking, curved surface), which lifts and turns from zero to 90°, incorporates a vertical lifting clamp featuring a ‘lock open’ and ‘lock closed’ feature, facilitating attachment and removal from the load. A specially designed cam jaw is made to safely lift curved surfaces and flat plate.

Dale Kelly, engineering manager at Caldwell’s J. C. Renfroe & Sons brand, said:

“The TLC’s main purpose is to lift pipes, but it can also lift any curved surface that meets the clamp’s minimum radius specifications. The minimum radius is different for each tonnage of clamp, but it can lift any size from the minimum radius up to a flat plate. As the clamp gets bigger the minimum radius of plate needs to get bigger. For instance a 1USt clamp can lift a smaller pipe than the 10USt version.”
