Demolish tall buildings with Kobelco’s new SK400DLC, SK550DLC excavators

Kobelco SK550DLC-10

Kobelco’s new SK400DLC-10 and SK550DLC-10 excavators are designed for tearing down buildings eight to 9 tales excessive.

The crawler excavators may be configured 4 alternative ways via a joint system beginning on the widespread base increase for 3 attain lengths and for digging.

For demolition of decrease ranges, the connected separate increase has a working top as much as 48 toes for the SK550D and 45 toes for the SK400D.

When needing further top, the ultra-long attachment may be added to attain 81 toes of attain for the SK400D and 90 toes for the SK550D. The peak may be shortened on the attachment by about 10 toes by eradicating the increase insert, whenever you don’t want most top however want greater than the separate-boom top.

For digging, the excavators can attain a depth of about 20.5 toes with the separate increase. The excavators may be geared up with crushing instruments as much as 5.3 tons on the separate increase and as much as 3 tons on the ultra-long attachment.

Kobelco designed the increase system for fast meeting and teardown. The increase attachment is linked by hooking the higher pin after which fixing the separate opposing pins on the decrease aspect. The increase attachment joints have hydraulic quick-coupler connections mounted on the aspect.

The ultra-long attachment has a storage and transport top of simply 7 toes 3 inches. Additionally to assist transport, crawler width may be retracted on the push of a button to 9 toes 9 inches, and the counterweight may be separated into two elements.

For decreasing silica mud, Kobelco made water suppression customary, with plumbing for the system from the bottom to the ends of the separate increase and high-reach fronts.

For gasoline economic system, the corporate added auto-idle and an ECO mode. The excavators even have an “S” mode to steadiness between work quantity and gasoline consumption, and an “H” mode for prime work quantity.

 

Aiding the operator

For operator security, a cab interference-prevention system was included as customary. The function sounds an alarm when the attachment device will get too near the cab, and it routinely prevents the attachment from hitting the cab. It detects the device’s place, so it could possibly create a protected working vary for the attachment, the corporate says. Operators can program a number of instruments into the system.

For working at heights, the cab may be tilted up as a lot as 30 levels to scale back operator fatigue. An emergency cab-lowering gadget is included, and a crosspiece on the suitable aspect window was added for added operator security.

Different customary options embody rearview and proper aspect cameras; increase, arm and jib holding valves to stop the increase or arm from falling if a hose is broken; two LED lights on the cab high; and a falling-object detector on the ultra-long attachment to deflect falling particles from the machine.

Full observe guides forestall crawler de-tracking, together with when traversing demolition rubble, the corporate says. Kobelco added thick upper-frame stomach guards, a swivel guard, journey motor guard and cylinder guards to guard parts from particles.

An auto-lubrication system routinely greases the higher physique at particular instances. The excavators additionally include the Kobelco Monitoring Excavation System (KOMEXS) telematics.
