The Caldwell Group - A manufacturer of below-the-hook lifting solutions
The Caldwell Group is a manufacturer of below-the-hook lifting solutions for crane, material handling and other applications. The company’s engineers are specialists in designing bespoke solutions for the world’s most challenging, heavy duty projects. The product range is varied and includes lifting and spreader beams, vacuum attachments, remote releasing hooks, and gantry cranes.
Caldwell Spreader Beam for Vita Load Navigator
Rockford, Illinois-based The Caldwell Group Inc. manufactures the spreader beam component of Vita Inclinata Technologies Inc.’s load navigator system.
The propulsion (fan) driven product is a remotely operated, suspended load system that allows crane operation crews to precisely (to one degree) control and orient loads without guylines or being in the critical path of the load. The system dynamically adjusts to load sizes, crane movement, and wind conditions, allowing high-precision lifts even in the most challenging environments.
The load navigator is available in five versions in 20t (7 ft. and 11 ft.) and 40t (7 ft, 11 ft., and 15 ft.) capacities. The complete system weighs 1,650 lbs., 1,900 lbs., 1,800 lbs., 2,100 lbs., and 2,400 lbs. respectively. In each instance, the centerpiece is Caldwell’s Dura-Mod modular spreader beam, a versatile, lightweight alternative to fixed and multiple point below-the-hook solutions.
Dan Mongan, senior sales engineer / project leader at Caldwell, said: “The beams are perfect for integration into such an innovative solution. Each spreader system consists of a pair of end units 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 load navigator system offers direct user-controlled positioning using a wireless control pendant, and features a position hold function, that keeps the load stable in a pre-set orientation, despite wind or slewing impacts on the load. Broomfield, Colorado-based Vita Inclinata reports a 20-50% increase to productivity, depending upon load parameters.
Derek Sikora, chief technology officer at Vita Inclinata, said: “We’re combining with specialists in their respective manufacturing fields—like Caldwell—to create a safety ecosystem that ultimately results in safer, more productive operation. Companies like DPR construction have identified our solution as a game-changing technology where analog systems have been the solutions of choice for generations.”
He added: “We can point to 300% reduction to crane fatalities and 63.1% reduction to crane-related injuries when utilizing the load navigator.”
Josiah Rausch, crane tech manager at Creative Lifting Services, said: “Using the Vita load navigator meant we did not have to have riggers run through an obstacle course, making it much more efficient and safer for the crew.”
- Vita will use this week’s CONEXPO-CON/AGG show in Las Vegas (Festival Grounds, F8552) to explain to construction stakeholders how the company’s load stabilization and Internet of Things (IoT) technology combine to add productivity and safety below-the-hook.
