Hyster H3.5FT Fortens Specifications

Basic Information

The Hyster H3.5FT Fortens is an LPG-powered, counterbalanced forklift truck manufactured from approximately 2018 to 2025. This rider-seated model is engineered for demanding indoor and outdoor material handling tasks requiring a rated load capacity of 3500 kg. The machine is available with a choice of PSI 2.4L LPG engine, Kubota 2.5L LPG engine, or Yanmar diesel options.

The Fortens series represents one of the toughest and most fuel-efficient internal combustion forklifts on the market, designed for medium-duty applications with very low operating costs and continuous power in the toughest indoor and outdoor applications. The durable powertrain is computer controlled, protected and managed by the Pacesetter VSM electronic management system featuring a CANbus communications network. The electronically controlled DuraMatch transmissions provide smoother directional changes to eliminate shock loading and extend the life of the clutch packs.

These transmissions offer unique and patented features managed by the VSM, such as the Auto Deceleration System, which contributes to extending brake and tyre life and reduces the frequency of required changes. If the Autospeed Hydraulics option is selected, when lifting a load the engine speed is automatically increased to provide full hydraulic power, with the Pacesetter VSM maintaining current travel speed or preventing travel until the operator steps on the accelerator, simplifying operator actions and increasing productivity.

The Hyster H3.5FT Fortens is a four-wheeled forklift with a load capacity of 3500 kg or 7716 lb at a 500 mm or 19.7 in load centre. The nominal load at the centre of gravity is 3.5 t. Its design prioritises stability and manoeuvrability in demanding environments. The machine is fitted with superelastic tyres as standard , with pneumatic options available. The tyre configuration is 2x2, indicating two wheels on the front drive axle and two wheels on the rear steer axle. The transmission type is Automatic Powershift with DuraMatch 1-speed or optional 2-speed configurations.

The service weight of the machine is 4799 kg or 10580 lb. Weight distribution with full load places 7319 kg or 16136 lb on the front axle and 980 kg or 2161 lb on the rear axle. Without load, weight distribution shifts to 1797 kg or 3962 lb on the front axle and 3002 kg or 6618 lb on the rear axle.
