How to choose new jersey barrier clamp
The weight of the barrier
Motorway New Jersey barriers weigh up to several tonnes per element: the model is chosen on the heaviest piece, with the jaw length matched to the length of the element.
Rubber or steel
Rubber jaws do not damage the surface but leave a slight black mark and wear on rough surfaces; steel jaws with pointed projections penetrate the concrete and grip better in intensive use.
Parallel faces
The clamp grips any concrete element with two parallel faces within the jaw opening: barriers, blocks, kerbs, precast walls.
The crane
It is used under mobile cranes, truck-mounted cranes and overhead travelling cranes: the clamp weight, 220 or 430 kg, is added to the load.
New Jersey barrier clamp: the most common questions
List price from 3,000 € + VAT for the 5,000 kg model; 6,000 and 8,000 kg and steel jaws are confirmed in the quotation.
The clamp is lowered onto the element, closes when lifted and releases when set down: the operator does not touch the barrier and nobody works under the load.
Yes, they are subject to wear, especially on rough and uneven surfaces: they are replaceable; for intensive use, steel jaws are the better choice.
Compliant with UNI EN 13155 and Machinery Directive 2006/42/EC, with CE marking, capacity plate and declaration of conformity.
