Heavy Duty Beam Clamp with Shackle (WJC Type) | 1T – 10T Adjustable Girder Clamp
The WJC Type Heavy Duty Adjustable Beam Clamp is specifically engineered to solve these operational bottlenecks. Equipped with an oversized integrated shackle and a robust, reinforced chassis, it converts any standard I-beam or H-beam into a versatile, high-capacity anchor point capable of handling multi-directional and angled rigging applications.

Safe Use Guidelines: Angled Lifting WLL Reduction
When executing oblique or angled lifting using the shackle beam clamp, the original vertical Working Load Limit (WLL) must be derated dynamically to ensure structural safety.
0° (Vertical Lift) —-> 100% WLL (Full Capacity)
0° to 15° (Slight Angle) —-> 83% WLL (17% Reduction)
15° to 30° (Medium Angle) —-> 66% WLL (34% Reduction)
30° to 45° (Max Angle) —-> 50% WLL (50% Reduction)
FAQ
What is the difference between WJC beam clamp and plain beam clamp?
WJC type includes a shackle suspension point, allowing easier attachment for chain hoists, slings, and pulling systems.
Can WJC beam clamp be used for angled pulling?
Yes. It supports side loading up to 45° and cross loading up to 15°.
What beam sizes can it fit?
Standard models fit beam flange widths from 75mm to 350mm depending on capacity.
