This is a technical specification and user instruction document for the Modulift MOD 50 Spreader Beam, a modular lifting apparatus rated at 50 tonnes Safe Working Load (SWL) at a 21-foot span with a 60-degree Base to Sling angle (BSA). The MOD 50 consists of one pair of End Units and Drop Links, with intermediate struts available in various lengths to achieve spans ranging from 3 feet to 42 feet in 1-foot increments. Component specifications include End Units and Drop Links each rated at 25 tonnes Working Load Limit (WLL), with individual strut weights ranging from 70 pounds (1-foot strut) to 285 pounds (12-foot strut). The system requires M20 x 65 Grade 8.8 high-tensile bolts with a tightening torque specification of 110 pound-feet and a 30-millimeter spanner size.

Assembly and operational procedures require that trained personnel follow safe slinging practices in accordance with ASME B30.20-2013 standards. Critical safety requirements include ensuring the Base to Sling angle is 45 degrees or greater, never exceeding stated SWL limits as specified in the included Load v Span table, maintaining proper top sling length, ensuring Drop Links hang vertically, and never suspending loads from the tube or flanges. The document provides detailed load capacity tables for spans of 3 to 42 feet across three sling angle configurations (45°, 60°, and 70° BSA), with corresponding minimum sling lengths and recommended end unit configurations. Personnel must verify component ID plates, check all flange pairs for debris before connection, and conduct a thorough safety inspection by a competent person before lifting operations.
