50 Tonne Modular
Spreader Frame

The MULTI-F50 is a 50 tonne modular spreader frame engineered for four-point lifting applications requiring greater lifting capacity whilst maintaining exceptional load stability. Manufactured using modular corner points and interchangeable spreader beam struts, the frame can be configured up to 9m x 9m.
MULTI-F50 Capacity Checker
Enter the required frame length, width and top sling angle to check the available Working Load Limit for that configuration.
MULTI-F50 Capacity Table
Working Load Limit varies with frame length, width and sling arrangement. Select the appropriate sling angle and use the table to check the capacity for your frame configuration.
Capacities shown are based on a maximum 30° STV (Sling to Vertical) and the selected frame dimensions.

MULTI-F50 Technical FAQs
What is the maximum working load of the MULTI-F50?
The maximum Working Load Limit is 50 tonnes. Allowable capacity depends on the selected frame length, width and sling arrangement.
What is the maximum frame size?
The MULTI-F50 can be configured up to 9m x 9m using compatible modular struts and corner units.
How is the frame assembled?
The frame uses four MULTI-F50 corner units with compatible Multi-50 modular struts to form the required rectangular configuration.
Does capacity remain the same at every frame size?
No. Working Load Limit can reduce for some frame geometries, so the applicable capacity data must be checked for the selected length and width.
What shackles are required?
The specified upper shackle is 35Te Standard Bow Shackle. The specified lower shackle is 25Te Standard Bow Shackle.
Can Multisec check a project-specific lift?
Yes. Send the load, lifting centres, required frame dimensions and sling arrangement to the Multisec team for configuration support.
