KOBELCO has unveiled two new machines for the European demolition market featuring the manufacturer’s NEXT system.
The SK400DLC-10 and SK550DLC-10 have been developed following feedback from dealers, customers and operators.
Kobelco said the SK400DLC-10 is based on the “highly acclaimed” SK350LC-10, sharing the same turbo-charged Stage IV-compliant engine and hydraulic system, while the SK550DLC-10 is based on the larger SK500LC-10.
The manufacturer said the use of Kobelco’s NEXT system means the machines can be adapted for multiple applications including high elevation demolition projects and breaking up foundations.
Both machines boast four “ultra-long” attachment configurations and can work to a maximum height of about 24.7m and 27.5m respectively. Kobelco said the separate boom configuration is “ideal” for work on lower floors of tall buildings where concrete is at its thickest.
The maximum working depth of the SK400DLC-10 is 6,210mm, while for the the SK550DLC-10 the figure is 6,260mm below ground level. Each boom attachment is reinforced for increased durability and reduced structural fatigue, and has a block structure to simplify the assembly/disassembly process and reduce downtime.
Kobelco explained that another benefit of the NEXT system is the low storage height of the ultra-high attachment when collapsed. This attachment is designed with the jib and arm cylinders crossed over the shorter inter arm, while the back of the arm remains flat. “As a result, the height of the attachment in its stored position is approximately 2m, which means that it can be transported between projects on a standard trailer, saving significant logistical costs,” the manufacturer stated.
For increased comfort and safety, the demolition-specification cabin can tilt up to 30-degrees so the operator can “maintain a comfortable posture” during high elevation work. Kobelco said the pillar-less design gives the operator an unobstructed upward view, while parallel windscreen wipers and washers on the front and top windows also boost visibility.
Other safety features include a cab interference prevention system, which sounds an alarm and stops the machine from allowing the working tool to come into contact with the cab during operation. The working radius and stability of the machines are calculated from the position of the attachment and the operator is warned with an alarm when stability is compromised via the stability warning system.
Both new machines also feature rear view and right side cameras, a loudspeaker system, falling object deflector and long-life LED lights.
Peter Stuijt, Kobelco product marketing manager said, “We are very pleased to finally launch the SK400DLC-10 and SK550DLC-10 in Europe after many years of important research and development. Kobelco already has an excellent reputation in Japan’s demolition sector, and we are proud to now be able to offer our proven demolition machines and technology to our European customers.
“The NEXT system is designed to save significant costs and time on the job site, as only one machine is needed for both high reach and low level demolition work. Attachments can be changed in around 30 minutes, and the machine can be transported easily on a regular trailer. As the machines are designed to operate in tough environments, much consideration has also been given to the lifespan of the equipment.
“Many of the components have been reinforced for extra durability and additional features, including the double element air cleaner, full track guides and water spray, further increase longevity. These are just some of the many reasons why we have already sold a number of these machines to dealers across Europe.”
