THE NEW Seddon Atkinson 401 is based on one of the most successful British trucks ever produced.
But in developing our new vehicle we've done a lot more than just 'update' the 400.1n fact we analysed every component and factor that affects a vehicle's overall operating efficiency and wherever we felt it was possible to improve the specification, that improvement has been made.
The result is the outstanding Seddon Atkinson 401, a vehicle designed to meet the operating demands of the next decade.
A 24-volt insulated return electrical system has been retained for the 401, but it has been completely redesigned to reduce main tenance and improve reliability.
On specific circuits manually resettable circuit breakers have been added to the electrical design to solve the problems experienced with standard fuse protection.
All the electrical components are centralised into a console which is situated in a forward position on the engine tunnel and no cab trim or panel sections need be removed to gain access to the electrical components.
The suspension on the 401 is based on advanced parabolic road springs. The minimum leaf suspension has the same capacity as multi-leaf arrangements whilst offering greater reliability and a saving in weight. High corrosion risk areas are formed out of high grade SMC (sheet moulding compound) materials of exceptional strength and durability.
The areas covered are the removable quarter panels, the grille panel, the bumper bar, the under bumper air spoiler and the wings.
Further safeguards are provided by Zintec coated door and underfloor panels.
In designing the 401 great consideration has been paid to the comfort and well-being of the driver.
From the laminated windscreen and the extended instrumentation to excellent ride characteristics and minimum noise levels, no detail has been overlooked.
The working environment created provides genuine cab luxury and a greater degree of driver safety
