Demolition Machine

Designed and built to save time and get you up and working!! The KOBELCO demolition machine utilizes a common use type base boom and exclusive NEXT attachment joint for the Ultra long front, boom insert and the Separate boom. KOBELCO’s demolition machines with the exclusive NEXT joint systems are made so you can set up or change work fronts quick and easy to get the job done. With the ability to change tools on site and work at multiple heights with a single machine, the productivity is maximized with the needs of the job. The machine can be quickly set up and adapted to meet the job requirement and be use for the full duration of the job instead of swapping out machines. Due to the unique structure of this attachment, transport can be completed safely and with just a few steps. Add that to the excellent fuel savings and machine durability, KOBELCO helps provide the owner reduced operational costs, less downtime and greater return on investment. KOBELCO’s SK350DLC, SK400DLC, SK550DLC demolition machine is the next generation of high performance and cutting edge technology. It’s ready to go to work for you.

Focus on operation rate resulting in a machine with common use type base boom Previous demolition machines had a structure that basically did not allow attachments to be exchanged, meaning one complete machine was required for each specification. Having machines each dedicated to its specialty was useful onsite, but this meant that the operation rate was low and users were required to own multiple machines. KOBELCO's solution was to develop a machine structure that enabled one machine to be adapted to multiple specifications. Our solution took form in the shape of the machine with common use type base boom.

The NEXT system, created with focus on the site A machine with common use type base boom is transported by separating the main body and its attachments, requiring less time for set-up after arriving onsite. KOBELCO studied in detail how the assembly work could be completed safely in a short time. We threw out the previous fixed concepts about attachments and developed an innovative attachment that incorporated our various ideas, resulting in the NEXT system.

Work setups done quickly and safely! The new-generation NEXT demolition attachment

NEXT attachment The new-generation NEXT demolition attachment for the demolition machine with common use type base boom was designed by KOBELCO without being limited by existing concepts. Each boom attachment has a block structure that simplifies assembly/disassembly and transport, and the attachments employ our original NEXT joint system. The piping can be connected easily, and the steps for attachment assembly/disassembly from pressure release to pin fixing can be completed safely in a short time.

Attachments and base machine designed for easy truck transport

■ NEXT joint system KOBELCO's original joint system was developed by testing the assembly/disassembly process extensively. The boom attachment can be connected just by hooking the upper (backside) pin and fixing with the separate opposing pins on the lower side (bottom side). Upper pin

Quick hitch piping

[NEXT ultra long attachment specification] The 3-piece NEXT ultra long attachment is designed with the jib cylinder and arm cylinder crossed over the short inter arm, and the back of the arm is flat. The height while in the stored state has been lessened to approx. 2m to lower the entire height during transport.

Upper side (back side): Pins just need to be hooked. There is no need to insert/remove the pins.

Left/right split pins

Guide

Left/right separate opposing pins do not need to be removed

Lower side (bottom side): Guided left/right separate opposing pins make it easy to position the pins.

■ Main front boom [NEXT separate boom specification]

■ Side-mounted hydraulic piping

Assembly of the separate boom simply means connecting the main front boom with which the jib cylinder foot section is integrated, to the all-purpose base boom using the NEXT joint system. This saves on the work otherwise required to connect the jib cylinder.

All attachment joints have the hydraulic piping mounted on the side, adopting hydraulic multi-coupler system for connecting sections.

A hydraulic circuit for the quick-hitch arm that allows quick and easy fitting of the front attachment is supplied as standard.

Short inter arm Cross cylinder layout

Flat arm back

Hydraulic crawler extension / retraction mechanism [SK400DLC / SK550DLC] Crawlers can be retracted to reduce crawler width to below 3m for ease of transport. The hydraulic system makes light work of extending or retracting with crawler shoes remaining on ground.

Two-part counterweight

[SK400DLC / SK550DLC]

The counterweight can be separated into two for transport. One part forms a case into which the other part is housed. It looks neat and uncluttered, and assembly/disassembly is faster than with an integrated counterweight.

Boom attachments can be changed easily, enabling a high machine operation rate

New environmental engine A new electronically controlled engine with high power and low fuel consumption is installed. Par ticulate matter and NOx emissions are suppressed through the engine’s high combustion efficiency, exhaust gas after-treatment equipment, and urea SCR system. The engine also conforms to EPA Tier IV Final regulations.

Separate boom specification KOBELCO has pioneered the development of the separate boom in Japan, and the NEXT separate boom is the product of a wealth of technologies built up through long experience in this field. By attaching a large nibbler, demolition is completed swiftly and efficiently, whether it’s the lower floors of tall buildings where the concrete is thickest, or basement floors and foundations. Working ranges at machine foot are extensive, and the maximum working depth is top level in all classes.

Safety

Enhanced safety functions to assist the operator in production and performance New cab interference prevention system The cab interference prevention system is standard on the SK350DLC, SK400DLC, SK550DLC. This feature sounds an alarm and prevents the machine from allowing the working tool to come into contact with the cab during operation. Current tool position can be detected with high accuracy so the tool can be moved at close range near the cab , resulting in increased safe working range.

■ System operation As the working tool approaches the cab, alarm is sounded before any contact can occur, and the machine automatically prevents tool from making contact with the cab.

■ System configuration The system calculates the various boom, attachment and idler link angles to create a proximity to the cab in order to prevent cab interference.

Tilt cab Cab support to allow tilting up to 30° is supplied as standard. The operator can maintain a comfortable posture during high elevation demolition work, suffering less fatigue over long working periods.
