The GT Viper Adjustable Large Beam Clamp YS WJC is a heavy-duty mechanical beam clamp from GT, designed to provide a secure beam-mounted attachment point for compatible lifting and material-handling equipment. Its adjustable jaws fit a range of beam flange widths, while the special jaw design applies load away from the flange edge to help reduce flange stress. With an easy mounting arrangement and matt black finish, it is intended for professional lifting operations on suitable structural beams as part of a properly planned lifting arrangement.
Select the GT Viper beam clamp by matching both its marked working load limit (W.L.L.) and jaw opening to the beam flange and lifting application, as capacity alone is not sufficient. The listed range has jaw openings of 125β204 mm or 125β305 mm and product weights from 12.5 kg to 24.5 kg; never exceed the marked W.L.L. The clamp meets the W.L.L. performance requirements of BS EN 13155, is marked in accordance with BS EN 13155 and has a minimum breaking load of four times the W.L.L. A 2.1 certificate and Declaration of Conformity are available; check the supplied documentation, including UKCA or CE marking where required, before use. -

Frequently Asked Questions
What is the GT Viper Adjustable Large Beam Clamp used for?
What is the GT Viper Adjustable Large Beam Clamp used for?
It is an adjustable beam clamp for attaching compatible lifting equipment to suitable structural beams. It is available with 16,000kg or 20,000kg working load limit (WLL) options and a 203β457mm jaw opening range.
How do I choose the right WLL and jaw opening for this beam clamp?
How do I choose the right WLL and jaw opening for this beam clamp?
Choose the WLL that is suitable for the load and complete lifting arrangement, then confirm the beam fits within the 203β457mm jaw opening range. The selected clamp, beam and connected equipment must all be suitable for the intended load, and the WLL must not be exceeded.
Who is the GT Viper Adjustable Large Beam Clamp suitable for?
Who is the GT Viper Adjustable Large Beam Clamp suitable for?
It is intended for professional lifting and rigging applications where an adjustable beam clamp is suitable for the structural beam and lifting arrangement. The user must confirm the beam condition, jaw fit, WLL and intended loading before use.
Where can the GT Viper Adjustable Large Beam Clamp be used?
Where can the GT Viper Adjustable Large Beam Clamp be used?
Use it only on compatible structural beams within the specified 203β457mm jaw opening range, with the clamp positioned and loaded as instructed. The supplied product information specifies special jaw loading away from the flange edge.
Why is the jaw loading position important on this adjustable beam clamp?
Why is the jaw loading position important on this adjustable beam clamp?
The product information specifies loading away from the flange edge, so the clamp must be positioned and used in the intended arrangement rather than treated as a universal beam connection. The supplied information also references BS EN 13155 performance and marking, with 2.1 and Declaration of Conformity documentation available where applicable.
When do LOLER and PUWER apply when using this beam clamp?
When do LOLER and PUWER apply when using this beam clamp?
For lifting equipment used at work in Great Britain, LOLER requirements for safe use, thorough examination and inspection should be considered. PUWER may apply to associated work equipment. Neither regulation is product certification.
