The Yale ERP040VTL/VFL is a series of 4,000-pound capacity integrated lithium-ion powered three- and four-wheel lift trucks. Both the ERP040VTL, the three-wheel model, and the ERP040VFL, the four-wheel model, buck the traditional approach in which a battery box replacement converts counterbalanced lift trucks from lead-acid to lithium-ion battery power. Instead, the trucks are designed from the ground up around a fully integrated, space-saving lithium-ion battery pack. The trucks pack the advantages of lithium-ion power, including fast charging, zero tailpipe emissions and no gassing in battery charging or maintenance processes, and lower energy costs compared to fossil fuels and lead-acid batteries.
Designing the truck around a fully integrated lithium-ion battery pack optimizes both form and function, realizing not only the advantages of the advanced electric power source, but also delivering key productivity benefits, including operator ergonomics and stability. An open-space design increases operator freedom to position feet and makes for easy entry and exit, maximizing comfort and convenience to help propel productivity, while a repositioned center of gravity enhances drive quality and improves truck handling in corners for greater operator confidence and performance.
