KOBELCO’s new high-reach excavator prioritizes flexibility and simple transportation between sites
Operators can extend or retract the hydraulic undercarriage on the SK650DLC-11 during transport or heavy lifting tasks
KOBELCO Construction Machinery U.S.A. launched its new SK650DLC-11 High Reach Excavator, a purpose-built building demolition machine engineered to deliver the reach, power, versatility, and transportability required for demanding demolition applications.
The SK650DLC-11 joins KOBELCO’s growing lineup of demolition machines, including the SK300 and SK350 Straight Boom models and the SK350D and SK1300D High Reach demolition excavators.
Powered by a 463-hp Isuzu Tier 4 Final engine, the SK650DLC-11 combines multiple boom and arm configurations with a hydraulic variable undercarriage, a demolition-specific tilting cab, and an attachment connection system designed to simplify setup and transport.
In its maximum high-reach configuration, the SK650DLC-11 provides up to 92 feet 7 inches of pin height with an 8,160-pound tool. For applications requiring increased tool capacity, Separate Boom configurations can accommodate tools weighing up to 13,450 pounds
The SK650DLC-11 has an operating weight of approximately 178,100 pounds and is engineered for efficient disassembly and transportation between job sites. With the counterweight removed, the base machine weighs approximately 109,000 pounds, helping simplify transportation and machine setup.
“The SK650DLC-11 was purpose-built to give demolition contractors more capability from a single machine,” said Dan Collins, director of product development for KOBELCO Construction Machinery U.S.A. “By combining multiple front configurations with a shared main boom, a variable undercarriage, and features designed to simplify assembly and transportation, contractors can configure the machine around the demands of the job rather than compromise between reach, tool capacity, and mobility.”
Operators can select from four front configurations
At the heart of the SK650DLC-11 is a multi-configuration attachment system that allows both a Separate Digging Boom and 3-Piece High-Reach Attachments to be used on a single base machine through a shared main boom.
An Insert Boom is compatible with both configurations, giving contractors four front arrangements:
- Separate Digging Boom: 50 feet 2 inches pin height with a maximum 13,450-pound tool
- Separate Digging Boom + Insert Boom: 59 feet 9 inches pin height with a maximum 13,450-pound tool
- 3-Piece High-Reach Attachment: 83 feet pin height with a maximum 8,160-pound tool
- 3-Piece High-Reach Attachment + Insert Boom: up to 92 feet 7 inches pin height with a maximum 8,160-pound tool
The KOBELCO Separate Boom design incorporates a two-piece structure with an additional articulation point, providing increased flexibility in positioning the attachment and supporting overhead, close-range, and below-ground-level demolition work.
Enhance stability even further with the variable undercarriage
The SK650DLC-11 features a newly developed hydraulic variable undercarriage engineered specifically for demolition applications.
For transportation, the undercarriage retracts to approximately 10 feet 6 inches wide. At the job site, it hydraulically extends to approximately 13 feet 9 inches, providing a wider working footprint to enhance stability during high-reach demolition and when operating heavier attachments.
The undercarriage can be extended or retracted while the machine remains on the ground. The operator controls the process from inside the cab, with no hydraulic hose reconnection or bolting required.
Demolition-specific cab improves visibility, comfort, and protection during high-reach work
A spacious interior and high-performance operator seat help reduce operator fatigue during extended demolition operations. Additional demolition-focused features include top and front P5A glass and Level II protection, as well as a falling-object deflector, cab interference prevention system, and stability warning system.
Operator amenities include an air-suspension heated seat, air conditioning, Bluetooth hands-free radio, charging port, public address system, telematics, and a large 10-inch monitor.
Designed for simple breakdown and faster transportation
Because large demolition machines frequently move between job sites, the SK650DLC-11 was designed to simplify assembly, disassembly, and transport.
The KOBELCO attachment joint system simplifies connection of the main boom and front attachment by allowing the upper pin to be hooked into position before the lower connection is secured hydraulically.
Hydraulic connections between the main boom and front attachments use a one-touch bayonet-style mechanism, allowing connections to be made without tools. The system is also designed to reduce the possibility of oil leakage caused by seal damage, helping improve reliability and reduce potential downtime during attachment changes.
The 3-Piece High-Reach Attachment also incorporates a patented cross-cylinder structure, which reduces overall height in the transport configuration and improves access during tie-down procedures.
New attachment stands serve as both storage stands and work platforms during attachment and removal. An optional hydraulic removable counterweight can also be removed and installed by one person, helping reduce labor requirements and the potential need for additional crane support.
