Yale Materials Handling Corporation has introduced a line of industrial engines from Power Solutions International Inc. (PSI) for its 3,000-7,000-pound Class IV and V lift trucks. Yale Flex Performance Technology is an advanced feature that comes standard with the new PSI industrial engines. This technology provides selectable performance modes that allow the truck’s performance to be tailored to operational demands, empowering operators to maximize fuel economy or enhance performance based on fluctuating demand.
The new PSI engines also offer extended service intervals and reduced periodic maintenance requirements, helping decrease maintenance and downtime. They feature hydraulic valve lifters instead of mechanical lifters, eliminating the need for valve adjustments, while a coil-over plug ignition design eliminates spark plug wires and associated replacement requirements.
