Following the introduction of the new, more stringent emission standards for Tier IV diesel engines, Rayco, a designer of environmental equipment for the landscaping and arboricultural sector, took the opportunity to develop a more efficient, powerful and compact decepper: the RG165T-R. Compared to previous designs, in which diesel engines were used, Rayco’s new decepper is designed around a powerful 165-hp gasoline engine.
As a result, the size of the equipment housing is reduced and some components such as after-treatment systems, diesel emission additives, and electronic components are eliminated. In addition to a robust gasoline engine, the RG165T-R also boasts a closed-loop hydraulic cut-off wheel drive system that transmits all of the engine’s horsepower to the cut-off wheel, allowing any task to be completed smoothly.
Decoupling is characterized by unique operational scenarios each cycle. The pump and motor must be able to cope with various obstacles at each work site. From technical support to fast, on-time deliveries and high-quality hydraulic components, Parker has enabled Rayco to develop a new decepper that has become an industry leader.
The first prototype of RG165T-R was built using the tilt-axis motor Parker series F12 182 cc together with a competing 90 cc closed-loop pump. However, during the early stages of testing, the 90 cc competing closed-loop pump showed performance and reliability problems, as well as potentially high lead times.
When Rayco decided to approach Parker’s applications teams, they suggested an alternative: the compact, high-performance 81cc C-series hydrostatic piston pump. And they immediately provided a specimen for testing. In subsequent testing of the Parker pump and motor combination, the team focused on performance by working together with Rayco engineers.
By integrating these two Parker components, Rayco engineers were able to exceed numerous performance goals. These include a 20 percent reduction in heat generation and a 10 percent increase in system efficiency compared with alternative test units. The C-series pump developed excellent power density, matching perfectly with the 182 cc F12 engine. The combination also made it possible to optimize the speed of the cut-off wheel, with a consequent 10 percent increase in output torque on the cutting teeth. Another unexpected benefit of the system was the reduction in the radius of wood chips in the machine, which reduced operational risks during the decapping process.
Parker’s Hydraulic Pump and Power Systems Division has been designing pumps and transmissions for more than 50 years. The division was formed following the acquisition of Denison Hydraulics by Parker’s piston pump business and merger with Parker Oildyne Division. Together, these two companies have expanded Parker’s offerings to include the high-quality compact hydraulic products and systems the division has pioneered since 1955.
