KOBELCO SK400DLC, SK550DLC Dash 10 Demolition Excavators

March 16, 2020

KOBELCO excavator models SK400DLC-10 and SK550DLC-10 are purpose-built for building demolition. The excavators reach to 81 feet and 90 feet, respectively.

The crawler excavators come with three-piece separate boom demolition front and high-reach front. The separate boom has a wide working range and simplifies the demolition of lower and underground levels, according to the company, and the ultra-long attachment enables the machine to demolish levels up to nine stories high. Large crusher tools, up to 3-tons on the ultra-long attachment and 5.3-tons on the separate boom, can be added for increased power and efficiency during demolition.

The SK400D and SK550D excavators are equipped with the KOBELCO exclusive NEXT attachment system. Each boom attachment is designed with a block structure that simplifies assembly/disassembly for fast and easy setup and teardown. Side-mounted hydraulic piping can be attached at ground level for ease and safety.

They have an integrated two-part counterweight; the first part forms a case in which the second part is housed, providing increased transportation options and quicker assembly/disassembly. Water suppression is standard and is plumbed from the base machine to the end of both the separate boom and high reach fronts.

Full track guides prevent crawler de-tracking, and thick upper frame belly guards, a swivel guard, travel motor guard, and cylinder guards provide added reinforcement to protect machine components from debris.

A new standard cab interference prevention system will sound an alarm and prevent the machine from allowing the working tool to come into contact with the cab during operation. A demolition spec cab with a tilt of up to 30-degrees, stability warning system, rear and right-side cameras, as well as boom, arm, and jib holding valves are also standard.

An auto-lubrication system automatically greases the upper body at specific times to reduce maintenance time before operation.
