GNT GSF40-189Li Lithium Stand-up Rider Forklift

The GNT GSF40-189Li is a lithium-powered stand-up rider forklift rated to lift 4,000 lb to a raised height of 189 inches (15.75 ft). The stand-up platform keeps entry and exit quick across a shift of repeated stops, and the compact chassis and tight turning radius are built to work narrow aisles where a sit-down counterbalance truck runs out of room.

Power comes from a 48V / 350Ah lithium battery that reaches a full charge in about 1.5 hours and needs no watering or equalizing — the upkeep that lead-acid forklifts demand. An AC drive system delivers torque for acceleration and grade without the brushes and contactors of older DC drives, and a Curtis instrument controller manages drive and hydraulics. The drive motor is a German-built AC unit.

Loads are handled on 42-inch side-shifting forks that adjust from 9.4 to 35.6 inches of spread, so the operator can square up to a pallet and shift it laterally without repositioning the whole truck. Hydraulic steering and an integrated multi-function handle put lift, side-shift, and mast tilt under one set of controls. The frame is steel, robotically welded for repeatable joint quality.

• 4,000 lb capacity for repetitive warehouse loading and unloading
• 48V / 350Ah lithium battery — roughly 1.5-hour fast charge, no watering or equalizing
• Stand-up rider platform for quick on and off at frequent stops
• Compact chassis and tight turning radius for narrow-aisle work
• Side-shifting forks for lateral pallet alignment without repositioning the truck
• Integrated multi-function handle controlling lift, side-shift, and mast tilt
• AC drive system for torque and smooth acceleration with reduced wear
• Curtis instrument controller and German-built AC drive motor
• Solid cushion load tires and polyurethane drive tires for smooth indoor floors
• Steel structure, robotically welded

The GSF40-189Li is built for indoor, smooth-floor work — loading and unloading trucks, loading docks, stock rooms, manufacturing floors, and general warehousing. Solid cushion load tires and polyurethane drive tires suit finished concrete; they are not intended for broken ground or outdoor terrain.

The narrow chassis and tight turning radius let the truck operate in aisles a sit-down counterbalance forklift cannot, recovering rack space without giving up lift height. The 48V battery pairs with a 48V / 65A charger rated at 480V — confirm a 480V power supply is available at the charging location before installation.

The GSF40-189Li carries a 3-year limited warranty. Specific coverage terms are confirmed at the time of sale.
