Features and benefits

Enhanced safety for employees and goods

The Komatsu Operator Presence System (KOPS) Plus, standard with AX50 series, locks out lift, lower, tilt and travel functions when the operator leaves the seat for more than three seconds. The forks cannot lower while the key is in the off position.

High-efficiency drivetrain

Our expertise in construction is behind the AX50’s full floating drivetrain. High torque delivered by a powerful engine is channeled through a heat dissipating aluminum transmission case and a rugged dust- and leak-resistant, double-seal U-joint design.

Multiple solutions to reduce operator fatigue

The fully hydrostatic power steering (FHPS) system offers you easy steering even at slow speeds and is engineered to eliminate kickback. Further improving operator feel are a small-diameter steering wheel and optional spinner knob for one-handed control.

Advanced ergonomic design

Designed to improve operator comfort and reduce fatigue, the Komatsu Komfort Zone is a dual floating structure: dampening mounts protect the frame from engine vibration; additional mounts isolate your operators from the frame. Sealed floorboard reduces engine noise and heat.

Angled ports to manage exhaust and dust

Hot engine air, dust and exhaust can affect operators over time. The AX50 series’ angled exhaust ports in the counterweight aim exhaust away while traveling in reverse. Exhaust vents low on the counterweight point away from the ground and don’t stir up dust.

Excellent sightlines front and rear

An unrestricted view of the fork tips and surroundings. The thoughtfully designed mast, console and low-profile dash provide you outstanding forward visibility. Upper corners of the counterweight are angled for clear sightlines in reverse.
