RotaBolt goes into battle

RotaBolts are being used on one of the most advanced tactical military bridging systems in the world. The latest version of the Dry Support Bridge (DSB) from WFEL uses over 1,000 RotaBolt tension control fasteners to help assure its structural integrity.

The DSB has a special lightweight construction featuring a series of aluminium modules which are pinned together using steel jaws. The design of the jaw system relies on a guaranteed clamping force across the bolted joints.

"We use RotaBolt tension control fasteners on each of these critical friction joints because we can rely on them to achieve and maintain the necessary clamping force and assure structural integrity" commented Jim Field from WFEL. "We have used these tension control fasteners on our bridges for many years and we know we can rely on them."

The new DSB can be deployed in under 90 minutes by just eight soldiers using a single launch vehicle. It can span a gap of 46 metres and carry up to 120 tonnes of load. An added benefit is that during the assembly process in the field, the RotaCap on top of each RotaBolt can be very quickly and easily 'finger checked' to see that the correct tension or load has been achieved.

The DSB's primary use is to support the momentum of attack and then ensure supply routes to the battlefield. The American Army has been using the original DSB system since 2003 and the latest version from WFEL has seen an increase in its load capacity and span.
