Following increasing demand for mid-sized excavators in the UK, Kobelco Construction Machinery Europe B.V. (KCME) have announced the launch of the all-new SK75SR-7 and SK85MSR-7 excavators that will be available from the Molson Group throughout England, Scotland and Wales.
With the first stock machines just arriving, in this article we take a closer look at the latest developments that really sets this machine apart.
These next-generation midi machines offer superior performance, greater efficiency and productivity with increased power and speed over the previous models, as well as one of the most sophisticated operator cabins in their class.
Several years of research and development, including valuable feedback from the European market on the previous -3 models, has led to a number of significant improvements in the new -7 models.
For example, the distance between the upper structure and undercarriage has increased by 20 mm in order to reduce damage by rocks, and the machines’ blade geometry has been improved, making it easier for operation in mountainous areas.
Other key improvements to the machines’ all-round performance include a 15% reduction in digging cycle time and 37% increase in arm digging speed for improved productivity, and a 23% increase in engine output. In addition, the machine’s bucket digging force has been increased by over 14% from 52.7 to 60.3 kN for superior power when working in areas of hard ground.
With their short radius designs, the SK75SR-7 is also ideal for working on jobsites where space is limited, such as in residential areas. The inclusion of Kobelco's innovative iNDr (Integrated Noise and Dust Reduction Cooling System), a superior method of noise suppression that promotes low noise, exceptional engine cooling, enhanced reliability and minimal machine downtime, reinforces the machines’ urban working credentials.
When it comes to fuel efficiency, the -7's feature three working modes that can be used to balance work volume with optimum fuel consumption. H-mode is used for heavy working, S-mode normal working and Eco-mode for prioritizing fuel efficiency over work volume.
Fuel consumption can be monitored and work modes can be changed via the 10-inch, color multi-display in the cabin, which is also the largest in class. Reinforcing Kobelco's commitment to reducing its carbon footprint, the SK75SR-7 & 85MSR-7 also complies with Stage V of the EU emissions standards, which are set to come into force in 2019.
Particular care and attention has been given to the new larger size cabin in order to promote increased operator comfort and safety. A Kobelco-branded Grammer heated air suspension seat is installed as standard for excellent shock absorption and superior operator comfort, and the armrests and joystick moves with the seat for optimum working position. The levers can also be moved horizontally in order to reduce operator fatigue.
The ROPS and FOPS II-compliant cabin provides increased operator safety while the LED-spec work lights and rear/side cameras offer excellent visibility on site. In addition, all maintenance related items are concentrated at the right hand side of the machine for easy access and the FOPS II guard can be opened for window maintenance.
Commenting on the introduction of the new models, KCME Product Manager, Peter Stuijt, says, “There is an increasing market for midi machines (less than 10 tonnes). With this in mind, we have spent a number of years developing our -7 machines in order to meet market demand as well as exceed the expectations of our European customers."
“As well as offering superior performance, greater efficiency and productivity with increased power and speed over the previous models, we expect the SK75SR-7 to be particularly appealing to the operators, who will appreciate the higher level of cabin comfort and improved safety features.”
