4.4.7.1 Manoeuvring aid, drawbar load reduction
Manoeuvring aid OptiTurn™
The OptiTurn™ manoeuvring aid improves the capability of the truck-semi-trailer
combination to travel around curves and traffic circles and to manoeuvre around
loading ramps.
Travelling on narrow streets, curves and traffic circles causes excessive tyre wear
and damage to tyre edges on curbstones. The limited area around loading ramps
also hinders the manoeuvrability of the tractor-trailer combination.
