• BRIDGNOR'rH, Shropshire-based British Springs is now distributing Weweler parabolic leaf springs.
The company already supplies more than 5,000 different types of laminated leaf springs for current and out of production trucks, vans and other vehicles. The addition of these parabolic springs from Holland now enables the company, it says, to offer ex-stock supply of suspension springs for virtually any make and model of commercial vehicle.
The main difference between laminated multi-leaf springs and parabolics is that a parabolic spring has a tapered profile — the thickness varies along the spring's length. This configuration results in a more progressive springing action and a reduction in spring weight for a given load capacity. Vehicles fitted with parabolic springs therefore, have a reduced unladen weight, affording higher payload capacity to the commercial operator.
These advantages may not apply where vehicles operate in harsh onioff-road environments, such as construction sites or quarries. Arduous duty cycles in these conditions dictate that suspension springs are subject to more regular refurbishment or replacement. In these circumstances the operator would me more likely to choose laminated multi-leafs.
Comments British Springs managing director, John Callard: "In the replacement sector, ex-stock availability of such an extensive range of both types of spring, through our UK distributor network, will provide commercial vehicle operators with the flexibility to meet the changing demands of long-term vehicle maintenance and repair."
