SK55SRX-6 mini-excavator benefits from advanced technology
Kobelco Construction Machinery Europe B.V. has launched in to Europe, the company’s first ever mini-excavator equipped with the Japanese proven iNDr (integrated Noise & Dust reduction) technology. This technology was first seen on the recently introduced SR class of Kobelco construction machines, and delivers improved dust filtration combined with better engine cooling. It also reduces engine noise to a new level, making the SK55SRX perfect for urban work.
The SK55SRX-6, with an operating weight of 5,020 kg (with cab) is the largest model in the family of 8 models. The smallest in the range has an operating weight of 1,650 kg (no cab). The demand within Europe for an excavator in this class is significant as it will appeal to all sectors - construction, builders, landscapers, plant hire and utility companies.
The SK55SRX is driven by the latest specification Yanmar 2.189 cc diesel engine and is exceptionally fuel efficient, even when delivering maximum levels of power and torque (28.3 kW/131 Nm). Kobelco say that a 23% fuel saving (over previous model in class) can be obtained with the machine in energy saving ‘S-mode’.
Kobelco has equipped the 5 t excavator with a dynamic triple-oil pump system (IFPS – Integrated Flow Pump System), which facilitates simultaneous fast and smooth work operation. This also contributes to improved fuel consumption from reduced engine workload.
With an overhang of just 190 mm, the SK55SRX complements the compact design of the latest range of Kobelco SR mini-excavators. Combined with exceptional lifting and working capacities, it is ideal machine for restricted working space.
The SK55SRX has a new dozer blade design to minimise over-spill during levelling operations. This reduces the work time by requiring fewer passes, which means less fuel.
Although defined as a mini-excavator, the SK55SRX has a new and slightly larger upper structure for improved stability versus lifting performance.
This also means the cabin area is over 820 mm wide giving improved visibility and operator comfort. The front window features gas damper cylinders for smooth and easy opening and closing. A skylight provides additional natural light and easier operation when working at height. The wide door opening makes it easier to get in and out of the cab.
The two speed travel - 3.7 km/h and 2.3 km/h - gives the operator the option of selecting the most appropriate speed for the work being done.
Work lights have been added to both sides for easier, safer operation in poorly lit situations.
Although this is the first excavator into Europe from Kobelco in this class, it is only a matter of time before others in the same family arrive.
Maximum digging depth is 3.900 mm, forward reach is 6,240 mm and digging height 5,930 mm. In standard specification, maximum operating width is 1,960 mm. For easier digging close to obstacles, the boom can be offset 70º to the left and 59º to the right. Bucket capacity is 0.16 m³. Bucket digging force is 35.2 kN and arm crowding force a maximum of 24.6 kN.
