The Multi 50 moves the range into serious capacity, carrying 50 tonnes at up to 9.5m lifting centres. It is the first system in the range to offer a 6m strut, so long spans can be made up with very few connections. Typical work includes modular building installation, bridge sections, vessel handling and heavy plant relocation.
How the system works
Each Multi-Sec spreader beam assembly is built from two end units and two drop links, with interchangeable struts bolted in between to set the span. Changing the lifting centres is a matter of adding or removing struts rather than hiring a different beam, so a single system covers every span in its range. Flanged connections are aligned with a podger or drift and fastened with the supplied bolts to a specified torque, and the whole assembly is built at ground level before the lift.
The same struts are compatible with Multi-Sec corner units, so this system can later be converted into a four point lifting frame by adding the corresponding corner units. Nothing already owned becomes redundant.

Working load limits are quoted at 30° sling to vertical. Load charts for 45° STV are available on request. Longer spans at reduced capacity are available; contact us with your span and load and we will confirm the configuration.
What is included
Each kit is supplied as a complete assembly: two end units, two drop links, the strut set for the selected lifting centres, connection bolts, and two top and two bottom shackles at the rated SWL for the system. Instructions for use, proof test certification and a full component schedule are supplied with every order.

Modular systems are rated by assembled span, so check the marked capacity for the configuration built. The same struts extend into modular lifting frames for four-point lifts, and slings complete the assembly.
Approvals and certification
Multi-Sec modular systems are DNV Type Approved to DNV-ST-0378 and designed, manufactured and tested in the United Kingdom in accordance with DNV-ST-0378 (Offshore and Platform Lifting Appliances), BS EN 13155:2003+A2:2009, BS EN 1993-1-1:2005 (Eurocode 3), EC Machinery Directive 2006/42/EC, LOLER 1998 and PUWER 1998. Manufacture is carried out under ISO 9001:2015 with accreditation to BS EN 1090-2 Execution Class 3. Every system is 100% proof tested before despatch and supplied with full certification and traceability.
Typical applications
Structural steel and bridge sections, precast and modular building units, plant and machinery installation, petrochemical and process plant maintenance, marine and quayside handling, offshore modules, and onshore and offshore wind components.
