Enerpac tools, such as the ZU4 pump provide safe and reliable performance to Cat Thailand’s Rayong facility.

SOME of the safest, most precise and energy-efficient tools in the Enerpac high-pressure hydraulic range are proving their reliability in service at Cat Thailand’s new Rayong facility for medium track type tractors. The 40,000 square metre facility, which commenced production in late 2012, produces medium-sized ‘dozers (27-40 tons) used in a range of mining, construction, resource development and infrastructure activities.

Enerpac tools are used in a wide range of tasks in the assembly of D6 and D8 dozers (with D5 and D7 to be added to production in the near future), including fabrication, maintenance, bearings, lifting, frame assembly and pressing.

The tools – including 10,000 psi hydraulic cylinders that can be half the size and weight of traditional mechanical tools – were supplied by authorized Enerpac distributor CAPE Industrial, which is also responsible for their servicing and maintenance in peak operating condition.

“What sets Enerpac and CAPE apart is the design and after-sales service. We have very specific requirements and the strictest safety standards at this plant and they were able to meet all of our needs in an efficient manner,” says Cat’s manufacturing engineering manager Mr Luanmuang.

“The safety of our people is most important to us at Cat so we need reliable tooling. Enerpac are a proven global leader and CAPE has given us very good delivery times and service,” he said. “Although this plant has only been operating in recent years, Cat has used Enerpac tools in its other plants in Thailand as well as Japan, the US and China. The quality of the products, plus the wide range of tools available, made this an easy choice for us,” Mr Luanmuang said.

Cat Rayong has introduced Enerpac technologies including:
RCH 606 60-ton hollow plunger cylinders used to precisely and without manual labour provide push-pull versatility in maintenance, testing and tensioning applications. The RCH cylinders are complemented by RRH307 and RRH 30-ton and 60-ton double-acting hollow plunger cylinders with powered extension/retraction.

Enerpac’s ZU4 series portable hydraulic pumps, which feature a powerful 1.25kW universal motor coupled with a totally new pump element design that reduces oil flow turbulence, producing an industrial workhorse with fewer moving parts and less friction. The high-efficiency design of the ZU and ZE series electric pump has higher oil flow and by-pass pressure, runs cooler and requires 18% less current draw than comparable pumps. Special models can be configured for particular applications.
