20 SERIES MECHANICAL SUSPENSION

The TMC 20 Series Suspension is a rugged suspension designed proven under harsh operating conditions. It is simple and lightweight in design to suit all types and makes of trailers.

Twin tapered bushes for both the equaliser and torque arm assemblies will enhance extended life with minimal maintenance.

Common length torque arms are used for both front and equaliser hangers for standard spread. Standard parts are used throughout allowing interchangeability between models.

Brackets and equalisers are designed to eliminate localised stress. Brackets are short to minimise torsional stress using investment casting for more homogeneous products with quality finishes.

Spring seats are designed to suit 127mm diameter round or the 152mm square axle beams.
