Agile and powerful — indoors and out

Electric forklifts can be hindered by wet and corrosive environments, but the nimble yet powerful 3-wheeled AM50 takes rain, snow, and salt water in stride. Its battery-powered sustainability, low maintenance design and unsurpassed turning ability mean it’s perfect for outdoor jobs that previously only engine-powered models could handle.

  • Excels in wet and corrosive applications
  • Nimble 3-wheel design
  • Engine power strength with zero emissions

Features and benefits

Exceptional durability

Limit your downtime even in harsh conditions. The AM50 series forklifts meet IP-X4 water-resistant standards and offer airtight, wet disc brakes, AC motors that eliminate motor brush/contact checks or replacements, weather-resistant controls and more.

A braking system for all seasons

An airtight, wet disc brake system assures dependable braking in most working environments. Unlike conventional drum-and-shoe braking systems, Komatsu’s wet disc brake system can go up to 10,000 hours with little more than oil changes.

High performance from Total AC

Achieve high performance with minimal costs with an AC system that utilizes advanced AC drive motors and an AC hydraulic motor. The Total AC system’s AC motors provide high operating efficiency, long operating life and longer run times than conventional DC-type motors.

More power for higher productivity

When you need great performance in bad surface conditions. All-around Dual Drive means the two front wheels are driven by independent AC drive motors for power and speed comparable to that of an engine-powered truck.

Nimble controls for more precision

Efficiency and precision from controllers designed to be light, compact, and simple to use. The controller itself is reliability tested and housed in a compartment that resists dust, water and other contaminants.

Designed to IPX4 Standards

A forklift for coolers, freezers, the outdoors, and that can be safely washed down when needed. AM50 models are designed to meet IP-X4 water-resistant standards, down to the control micro-switches, potentiometers and control signal circuits.
