Hyster S100FT Specifications
The Hyster S100FT is a high-capacity, cushion-tire,
internal-combustion forklift engineered for rigorous indoor industrial
applications requiring dependable lifting performance, strong structural
durability, and excellent operator control. As part of the Hyster Fortis series,
the S100FT incorporates advanced design concepts such as enhanced cooling,
electronic engine management, improved drivetrain durability, and optimized
ergonomics.
With a rated lifting capacity of 10,000 lb
(4,536 kg), the S100FT is commonly deployed in manufacturing facilities,
heavy warehouses, industrial production lines, paper mills, fabrication
plants, and freight terminals.
The S100FT blends rugged construction with modern reliability features,
while still maintaining accessibility for maintenance personnel. Its
industrial LPG or gasoline engines deliver strong torque at low RPM, a
key requirement for heavy palletized or irregular loads. The
Fortis-series operator compartment is designed for comfort and
visibility, featuring intuitive controls, reduced vibration, and
improved mast sightlines.
This model excels in smooth-floor indoor
operations where precise handling and powerful load management are
necessary. Its combination of durability, power, and low maintenance
requirements makes the S100FT one of the most valued heavy cushion-tire
forklifts in the Hyster lineup.
