Komatsu CX50 Series IC Pneumatic

Double tap to zoom

Overview

The fusion of advanced engine technologies and Komatsu’s unique hydraulic system enables the CX50 Series to achieve significant reduction in total operation costs and facilitates superior working performance. A fully electronically controlled engine with a 3-way catalytic system conforms to the latest emission regulations for a cleaner work environment. The CX50 challenges the conventional concept of the forklift.

Features

Durable Wet Disc Brakes

The wet disc brake system is sealed with oil to block dust penetration, providing durable, water resistant and fade resistant characteristics. Smooth, stable braking provides productivity and reliability in demanding operations.

The oil in a wet disc brake system is circulated through the brake oil cooler. This mechanism ensures stable braking under a heavy work load and prevents deterioration of the braking force that could be caused by raised oil temperatures. Komatsu’s unique cushioning valve enables controlled braking force that precisely reflects the pressure on the brake pedal.

Fully Hydrostatic Power Steering

The Fully Hydrostatic Power Steering (FHPS) system facilitates fully stationary steering as well as switchback operations using the small diameter steering wheel. The system has a superior response capability so that the operator can maneuver easily with a load even in a tight area

Dual Floating Structure Reduces Vibrations

A unique dual vibration cushioning system reduced vibrations in the compartment, steering wheel, control levers and the mast. Any vibrations transmitted from the engine or road surface are quickly absorbed. The system is friendly to both the operator and the load.

KOPS Plus Komatsu Operator Presence System

KOPS Plus – standard on the CX50 – locks out lift, lower, tilt and traveling functions when the operator leaves the seat for more than three seconds. They do not resume until the operator returns to the seat and resets the controls. A flashing yellow warning light alerts the operator when the KOPS lock is activated. In addition, the forks cannot be lowered while the key is in the off position.

Reduced Hot Air and Exhaust Gas

Two counterweight air outlets are provided on the left and right sides and an exhaust pipe outlet is provided at a lower position. This prevents the operator from being exposed to hot air from the radiator and exhaust gases while driving in reverse. The 3-way catalytic system also purifies the nitrogen oxide, hydrocarbons and carbon monoxide emissions.

Full Suspension Seat

The full suspension seat provides improved operator comfort. The deluxe seat features improved vibration resistance and reduced stress on the body. This seat features six-step reclining backrest, 6.7” slide distance backward and forward, seat cushion adjustable dial and a retractable seat belt.

Secure Operator Controls

The secure lever controls with minimum movement using fingertip operator for the F/R lever. The control levers feature contoured knobs for ease of control. A smaller steering wheel permits widened forward visibility along with the redesigned dashboard for complete fork tip visibility. Komatsu’s unique cushioning valve enables control of the braking force in proportion to the pressure on the brake pedal and improves the braking feel.
