Clark has launched electric variants of the GEX and GTX series of counterbalanced trucks. The three- and four-wheel electric forklifts have load capacities of 1.6 to 2 tons and lifting heights of up to 7075 mm. The series is available with two wheelbases. The GTX16/GEX16 has a wheelbase of 1312 mm. The GTX18/GEX18 as well as the GTX20s and GEX20s each have a wheelbase of 1420 mm.
Two parallel front-wheel drive motors, each with an output of 4.4 kW and 48 volt three-phase technology, ensure rapid acceleration of the vehicles and driving speeds of up to 16 km/h.
The Zapi Dual AC control is equipped with CAN bus technology. Three driving modes are available for energy-efficient use of the vehicle. Wear-free, regenerative braking with the engine brake and automatic speed reduction when cornering are also individually programmable. Safe use on ramps is ensured by the standard ramp function, which prevents the truck from accidentally accelerating or rolling backwards and ensures that the operator always has the truck under control.
The Clark Li-Ion solution consists of the Li-Ion battery including the battery management system (BMS) and a high-frequency charger. The battery power is 460 Ah for all models of the GTX/GEX series. This means that vehicles with a smaller wheelbase as well as those with a larger wheelbase have the same battery performance. The 48 volt (160 A) charger requires a high-voltage connection (CEE 16 A plug) and fully charges the battery in a good 2.5 hours. The charging status of the Li-Ion battery is shown on the vehicle display. During the charging process, the charger display shows the charging status. The BMS has a safety shutdown and thus ensures safe use of the battery.
Clark Li-Ion batteries are based on lithium iron phosphate technology (LiFePO4). With LiFePO4 batteries, no oxygen is released during the chemical reaction within the cells, which eliminates the risk of self-ignition or battery explosion. With 2500 guaranteed charging cycles, the service life of the Li-Ion battery is at least twice as long, and depending on the application even many times longer than the service life of a lead-acid battery. And even after that, the battery can still be used for 10 years or more for further uses. In addition, the LiFePO4 batteries are more environmentally friendly than, for example, lithium nickel manganese cobalt oxides (NMC batteries).
The Clark three- and four-wheel electric forklifts are available with extensive additional equipment so that they can be individually adapted to a wide range of operating conditions. The optional equipment includes different cabs, such as rain protection (steel roof), weather protection (steel roof and windscreen), partial (steel roof, front and rear window as well as PVC side panels) and full cab, mini lever or mechanical lever, blue LED warning lights , orange seat belt, attachments and additional safety options.
