With a rated capacity of 30 metric tons, this modular system provides a versatile alternative to traditional fixed spreader beams, allowing users to configure the frame to suit different load dimensions and lifting requirements.\u003c\/p\u003e\n\u003cp\u003eFeaturing a modular bolt-together design, the DM30-4 can be assembled in various square and rectangular configurations with spans ranging from 3 to 20 feet. This flexibility enables contractors, rigging professionals, and industrial operators to use a single spreader beam system across multiple projects, reducing equipment costs while increasing operational efficiency.\u003c\/p\u003e\n\u003cp\u003eThe 4-point lifting configuration helps maintain balanced load distribution, minimizes stress on lifting lugs and attachment points, and improves control during critical lifts. By maintaining proper sling geometry and reducing load distortion, the DM30-4 enhances safety and lifting performance when handling large, heavy, or irregularly shaped loads.\u003c\/p\u003e\n\u003cp\u003eDesigned for demanding industrial environments, the DURA-MOD DM30-4 is manufactured from high-strength steel and built to withstand repeated use in construction, manufacturing, energy, offshore, shipbuilding, infrastructure, and maintenance applications. Its knock-down construction allows for convenient transportation, storage, and assembly, making it an ideal choice for job sites where mobility and adaptability are essential.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLarge equipment skids\u003c\/li\u003e\n\u003cli\u003eStructural steel assemblies\u003c\/li\u003e\n\u003cli\u003eProcess modules\u003c\/li\u003e\n\u003cli\u003eTanks and vessels\u003c\/li\u003e\n\u003cli\u003eOffshore and marine components\u003c\/li\u003e\n\u003cli\u003eAerospace and military structures\u003c\/li\u003e\n\u003cli\u003ePrecast concrete elements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe box-frame arrangement distributes forces evenly across the load and helps maintain proper sling angles. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eModular Design\u003c\/h3\u003e\n\u003cp\u003eA major advantage of the DM30-4 is that it is built from interchangeable components:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCorner fittings\u003c\/li\u003e\n\u003cli\u003eSpreader sections (1 ft., 2 ft., 4 ft., and 6 ft. modules)\u003c\/li\u003e\n\u003cli\u003eBolt kits\u003c\/li\u003e\n\u003cli\u003eShackles and slings (supplied separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese sections can be combined to create square or rectangular lifting frames ranging from \u003cstrong\u003e3 Ft. to 20 Ft.\u003c\/strong\u003e in span.
