The GT Viper Adjustable Standard Beam Clamp is a heavy-duty beam clamp for securing lifting equipment to suitable beams. It provides a secure grip through simple mounting and an adjustable design that fits a wide range of flange widths and beam profiles. Its special jaw design applies the load away from the flange edge, helping to reduce flange stress during use. Capacity options are 1 t, 2 t, 3 t, 5 t and 10 t, with jaw opening ranges of 75β220 mm, 75β220 mm, 80β320 mm, 80β320 mm and 90β320 mm respectively.
Before use, select a clamp with a working load limit (W.L.L.) suitable for the complete lifting arrangement and the beam being used. Do not assume suitability from the adjustable range alone. The matt black clamp meets the W.L.L. performance requirements of BS EN 13155, has a minimum breaking load of four times the W.L.L. and is marked in accordance with BS EN 13155. Follow the relevant lifting-equipment instructions and site procedures before use.

FAQs GT Viper Adjustable Standard Beam Clamp
Who is the Viper Adjustable Standard Beam Clamp for, and where is it used?
Who is the Viper Adjustable Standard Beam Clamp for, and where is it used?
The Viper Adjustable Standard Beam Clamp is for buyers securing lifting equipment to a suitable steel beam. It is used where the selected clamp, beam profile, flange width and working load limit suit the complete lifting arrangement. Its adjustable design accommodates a range of flange widths and beam profiles.
How do I choose the correct WLL and jaw opening for this beam clamp?
How do I choose the correct WLL and jaw opening for this beam clamp?
Choose a working load limit (WLL) that suits the complete lifting arrangement and a jaw opening that matches the beam. The available options are 1 tonne with 75β220mm jaws, 2 tonnes with 75β220mm, 3 tonnes with 80β320mm, 5 tonnes with 80β320mm and 10 tonnes with 90β320mm.
Will the Viper beam clamp fit my steel beam?
Will the Viper beam clamp fit my steel beam?
Not automatically. Check the beamβs flange width and profile against the selected clampβs jaw opening, then confirm that its WLL is suitable for the beam and complete lifting arrangement. An adjustable range alone does not prove suitability.
How does the Viper Adjustable Standard Beam Clamp secure lifting equipment, and when should I check it?
How does the Viper Adjustable Standard Beam Clamp secure lifting equipment, and when should I check it?
It grips a suitable beam through its adjustable clamp design and simple mounting format. Before use, check the clamp, beam and lifting arrangement against the product instructions and site procedures. Its jaw design applies the load away from the flange edge, helping to reduce flange stress.
Why choose an adjustable beam clamp instead of a fixed-size clamp?
Why choose an adjustable beam clamp instead of a fixed-size clamp?
An adjustable beam clamp can accommodate a wider range of flange widths and beam profiles than a clamp limited to one fixed opening. The Viper still has to be selected for the correct WLL and checked against the actual beam; adjustability does not make it universally suitable.
What UK standard, legislation and safety markings should I check on this beam clamp?
What UK standard, legislation and safety markings should I check on this beam clamp?
The matt black clamp is described as meeting the WLL performance requirements of BS EN 13155 and being marked in accordance with that standard. Its minimum breaking load is four times the WLL, and the listing references UKCA or CE marking where required with a certification/specification sheet. For workplace lifting, follow the relevant equipment instructions and site procedures and check any UK legislation that applies, including LOLER or PUWER where relevant; a marking or standard must not be treated as proof that every lifting arrangement is suitable.
