By Kevin Swallow CARTWRIGHT GROUP says its longer semitrailers (LSTs) will use the “command rearsteer” technology because it is more versatile than current self-tracking rear-steer solutions.

The Altrincham-based body and trailer manufacturer is in the process of building its irst LST, says director Steven Cartwright, which is expected to be unveiled in January 2012. “We are inalising the design but we will initially use command [positive] rear-steer technology, which in this case is Tridec, as it is more versatile and reduces the tyre wear.

“With self-tracking rear-steer trailers, which are cheaper and lighter, you have to straightenup to slot the pin into place before reversing with three ixed axles – and there will be a lot of yards where this might not be possible,” he says.

Manufacturers developing maximum length longer trailers with a single rear-steer axle are yet to achieve a true 44-tonne GVW because they are unable to put the axle in the right position to achieve the required turning circle without compromising weight distribution.

Cartwright admits its company’s design is currently at 42-tonnes GVW. However, a reduced GVW could beneit operators that regularly cube-out and those involved with the pallet networks, as there is no height restriction with longer trailers.
