Deck Widening - Without Steer

  • Widens from 2.5m to 3.5m

Deck widening low loaders are used mainly where wide machines need to be transported into areas where access is difficult and roads are narrow. The wheels stay at 2.5m wide but decks can widen up to 3.5m to suit the width of the load.

Extendable Low Loader

  • Low height at 700mm allows high loads to travel legally
  • Extending to 15.2
  • Ramps fitted for track machines.

Loads that would normally be over height can be transported legally with the super low deck height. Extending to 15.2m with several other locking lengths to suit. Fitted with ramps this trailer becomes a versatile trailer able to carry track plant and machinery, substations, buildings etc.

This trailer is ideal for Long loads, and where height is an issue.
