Clark GEX16 GEX18 GEX20S GTX16 GTX18 GTX20S Forklift Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The Clark GEX and GTX series electric forklifts are 3 wheel and 4 wheel AC-powered counterbalance trucks built for demanding material handling applications. Clark Material Handling Company traces its origins to 1917 when it produced the first forklift truck in the United States. The GEX series (4 wheel) and GTX series (3 wheel) cover capacity ratings from 1600 kg to 2000 kg and are equipped with advanced AC drive and pump motors for smooth efficient operation. These electric forklifts feature programmable motor controllers for customized performance characteristics including travel speed acceleration profiles, and lift parameters. The GTX 3-wheel model offers a particularly tight turning radius, making it ideal for narrow aisles and congested warehouse environments. The GEX 4-wheel variant provides enhanced stability for heavier loads. Both series share common design philosophy with modular electrical systems and easily accessible service points. The battery electric power system eliminates exhaust emissions and reduces operating noise, making these trucks suitable for indoor operation in food processing pharmaceutical storage, and retail distribution centers. Regenerative braking extends battery runtime while providing smooth deceleration.
