Instruksjonsbok Volvo A25D - A30D

Introduction

Productivity The A25D and A30D have a well-matched drivetrain with a direct-injected, turbocharged, Volvo low-emission die- sel engine with intercooler. The fully automatic transmis- sion permits maximum utilization of engine power. Differential locks with 100% locking capability on all drive axles, as well as on the longitudinal differential, give very good traction and excellent off-road mobility even in extremely tough conditions.

Maneuverability

Articulated steering The powerful self-compensating, hydro-mechanical steer- ing is the secret behind the machine’s directional stability and ground-hugging agility.

Front axle The A25D and A30D have rubber springs and shock absorbers on the front axle. This permits high-speed hauls with maximum comfort. The three-point suspension enables the wheels to “walk over” obstacles, without the entire tractor oscillating. The suspension is maintenance- free, there are no grease fittings.

Hitch The 360° rotating hitch enables the tractor unit to oscil- late independently of the load unit, eliminating frame twist. This lets the wheels “walk over” all obstacles in the terrain, while maintaining ground contact at all times.

Bogie The Volvo bogie with high ground clearance and inde- pendent axle suspension provides up to ± 250 mm (10 in) of independent wheel movement. This gives the machine a smooth, “floating” ride. The body is kept hori- zontal regardless of ground conditions, resulting in less spillage. The bogie is maintenance-free.
