Safety & Comfort

Wet disc brake that safely stop the vehicle in any working conditions (Option)

The EX50 features Komatsu's original wet disc braking system that eliminates weakness of traditional drum brakes. With its built-in waterproof and dustproof mechanism, the braking system also delivers high durability with less brake shoe wearing. Because the braking system is enclosed, it does not require part replacement or overhauls for maintenance.* Regardless of your working conditions, it offers added reliability and safety of the EX50.

*Oil replacement and regular inspections are required.

Operator Presence Sensing (OPS) system automatically stops traveling and lifting when the operator leaves the seat (Option)

To avoid malfunctions and operations in the operator's unstable positions, the OPS system automatically prevents driving and loading when the operator is unseated. Indicators on the display panel inform the vehicle condition when it stops by the interlock.
This mechanism conform with ISO3691-1, one of the worldwide safty standards.

*This system is to safely stop the driving and loading function, and not intended to forcedly brake the vehicle.

What about ISO3691-1
ISO3691 refers to a series of safety standards for industrial trucks to facilitate safe working.

Greatly enhanced front/rear visibility achieved by improved top of the counter weight shape and expanded inner width of the mast

Cut-out for enhanced rear visiblity Inner width of the mast (FD100 2-stage free view mast)642mm[25.3in]

Improvement in the shape of the back portion of the rear weight enhances rearward visibility, which has been a blind spot for the operator. Moreover, arrangement of the chains outside of the mast allows the inner width of the mast to be expanded to 642 mm [25.3 inches] (FD100), ensure the good frontward visibility essential for safe operation.

The new-design seat features a high-support structure that always balances and securely holds the operator’s body, thus reducing fatigue during extended operation. It also provides retractable seat belt.


Komatsu’s original Hydraulic Suspension Cab (HSC) mount provides the ultimate in operator comfort even during extended operation

Komatsu’s original HSC mount system raises the operator’s cab from the vehicle body with a hydraulic suspension that absorbs most travel vibration, thereby helping to reduce operator fatigue.
