Kobelco announced the addition of the new SK300LC-11 and SK350LC-11 Straight Boom excavators to its growing lineup of building demolition equipment.
Designed to provide greater working height than conventional mono boom excavators, the new Straight Boom models combine increased reach and tool capacity with the stability, controllability and operator comfort expected from KOBELCO excavators. Both machines are purpose-built for demolition applications and equipped to handle a wide range of demolition attachments.
“As the demolition industry continues to evolve, Kobelco is committed to purpose-built machines that address the changing needs of demolition contractors,” said Dan Collins, director of product development for KOBELCO Construction Machinery U.S.A. “The expansion of our demolition lineup reflects that commitment, offering increased reach and tool capacity along with best-in-class quality, comfort and controllability.”
Built for Demolition
The SK300LC-11 and SK350LC-11 Straight Boom are powered by a 265-hp Isuzu Tier 4 Final engine utilizing SCR/DEF emissions technology without a diesel particulate filter (DPF). The engine provides the power and torque needed to operate heavy demolition attachments in demanding applications.
A case drain circuit comes standard, expanding compatibility with attachments requiring increased hydraulic drainage. Kobelco's in-cab hydraulic pressure release function further simplifies attachment changes by allowing the operator to release hydraulic pressure from inside the cab before disconnecting work tools or hydraulic hoses.
The Straight Boom configuration provides increased working height compared with conventional boom configurations while supporting substantial demolition tool capacities. The choice of standard or long arm configurations allows contractors to balance increased reach with greater tool capacity based on the requirements of the application.
Operator Comfort, Control
The operator-focused cab combines comfort, visibility and intuitive controls for demanding demolition applications. A seven-way adjustable heated air-suspension seat moves together with the armrests and hydraulic controls to help reduce operator fatigue and absorb shock. Redesigned pilot levers feature shorter strokes and horizontal movement for precise, responsive machine control.
A large 10-in color monitor and jog dial provide convenient access to machine settings, attachment flow adjustments, maintenance information and fuel consumption data. The monitor also displays a 270-degree view from the standard three-camera system, helping improve visibility around the machine. Hydraulic flow settings for breakers, nibblers and rotating grapples can be adjusted through the monitor, while settings for additional attachments can be added or changed to match operator and application requirements.
Additional cab amenities include automatic climate control, Bluetooth hands-free audio, USB charging and LED-backlit controls.
Demolition-Focused Safety
Both machines incorporate a range of features designed to enhance operator protection and machine visibility on busy demolition jobsites. The cab incorporates a Roll-Over Protective Structure (ROPS) along with heavy-duty Level II top and front guarding designed for demanding demolition environments.
Rear swing flashers and rear-facing work lights are integrated into the counterweight to help increase machine visibility around the jobsite. A total of seven LED work lights come standard, including two boom-mounted lights, two mounted at the front of the cab, one on the right side of the machine and two rear-facing lights integrated into the counterweight.
Remote Machine Monitoring Telematics
The Kobelco Monitoring Excavator System provides owners and fleet managers with remote access to key machine information, including operating hours, fuel consumption, maintenance status and machine location. Additional functions include an engine start alarm, geofencing and current and historical machine location information, providing added visibility for contractors managing equipment across multiple job sites.
