Forklift trucks vary considerably in their technical makeup, especially engine powered trucks, with the transmission being a defining factor. Forklift manufacturer Hyster has proved its patented DuraMatch transmission can benefit operational efficiency and help companies reduce costs.
In its simplest form, a "powershift" transmission transfers power from the engine to the tyres through a torque er, relying on the brakes to then slow the forklift. However, with developments in technology, transmissions can be the source of many operational benefits, and can be protected from driver damage. Peter Madoc-Jones, Product Marketing Manager for Hyster Europe, explains "Loading and unloading operations involve frequent forward and backward shuttling duties, which can put a strain on standard forklift transmissions".
Hyster’s DuraMatch transmission is available across the Fortens range of 1.6 to 9.0 Tonne capacity engine-powered trucks and features one, two or three forward speeds, depending on truck capacity and model. The transmission has been specifically designed to offer the best powershift transmission controllability on the market combined with reduced operating costs and improved driver performance.
The transmission is electronically controlled using an on-board electronic control unit, known as the "Pacesetter™ Vehicle System Manager" (VSM). In addition to the transmission, the VSM also controls all truck hydraulic and electronic functions and simplifies some operator functions.
"The system automatically slows the truck’s travel speed when the accelerator pedal is released without using the footbrake, helping to increase driver productivity, minimise brake pedal use and significantly reduce brake and tyre wear. We call this the Auto Deceleration System or ADS" comments Peter Madoc-Jones.
The VSM regulates oil flow through the forward & reverse clutch packs to reduce speed, and the deceleration rate can be tailored via the dash display, to suit the needs of the driver or application.
Even the most aggressive direction changes can be made smoothly, without using the brake pedal or even stopping the truck. The DuraMatch’s "Controlled Power Reversal" (CPR) feature simultaneously manages the engine RPM and activates control valves on the clutch packs, delivering a smooth direction change, without wheel spin. This contributes to improved productivity and reduced costs, prolonging the lifetime of the clutch, brakes and tyres, and optimises truck control.
