LPG engine upgrades on Yale forklifts

The changes offer customers a more powerful and efficient engine with improved productivity while lowering the total cost of ownership. 

For its feature-rich GLP20-35VX series, its standard-duty GLP20-25LX and its compact GLC20-35VX trucks, Yale has chosen to replace the previous Mazda 2.2 litre engine with a 2.4 litre PSI (Power Solutions International) alternative. 

Matthew Allen, Yale solutions manager counterbalance product, explains: “Compared to their automotive-derived equivalents, industrial engines in lift trucks are more powerful, fuel efficient, quiet, reliable and long-lasting. Much of this is down to the fact that they operate at lower RPM and this gives significantly more low-end torque – which is ideal in materials handling.

“Yale has worked with PSI for more than two and a half years to develop engines that are tailored to meet the demands of each application, incorporate the latest technologies for peak performance and surpass the performance of previous engines.   

“Over 30,000 hours of testing, incorporating a series of simulations, reliability measurements and engine dyno testing, have been completed on the new engine and after each highly accelerated life test (HALT) the engines were disassembled and inspected to verify that they continued to meet durability expectations.”
