R57 mini excavator

The RIPPA R57 PRO is a 5.7-ton class excavator engineered for contractors and operators who demand strength, efficiency, and long-lasting durability on the job site. Powered by the proven Yanmar 4TNV98C/4TNV94L diesel engine, this machine delivers a rated output of 38.1 kW (51 HP) at 2200 rpm with strong, stable torque for heavy-duty excavation.

Equipped with a fully electronic hydraulic control system, the R57 PRO optimizes fuel efficiency by up to 10% less consumption compared to previous models. The combination of high digging force, reinforced arms and boom, and a mine-spec undercarriage make this machine perfectly suited for utility work, construction, and tough conditions where reliability is essential.

With operator comfort in mind, the R57 PRO features an ergonomic cab with shock-absorbing seat, advanced noise/vibration reduction, integrated air conditioning, and multifunctional digital instrumentation — making long hours on the job more productive and less fatiguing.
