KOBELCO has introduced the SK300LC-11 and SK350LC-11 straight boom excavators designed specifically for demolition tasks. These high-reach machines leverage specialized boom configurations to improve efficiency and working height for heavy-duty site projects.
Why it matters
The straight boom design offers superior working height and tool capacity compared to standard mono-boom excavators, helping operators handle complex demolition workflows more effectively. These models aim to streamline performance by integrating advanced monitoring and safety features directly into the equipment.
The SK300LC-11 weighs between 69,200 and 72,300 lbs, while the SK350LC-11 ranges from 81,800 to 85,300 lbs. Both models are powered by a 265-horsepower Isuzu 6HK1 diesel engine that achieves Tier 4 Final standards without needing a diesel particulate filter.
The players
KOBELCO
A global manufacturer of heavy machinery known for excavators and construction equipment.
Isuzu
An automotive and engine manufacturer recognized for producing the diesel power plants found in heavy-duty construction vehicles.
The details
The excavators use a straight boom configuration to maximize vertical reach and tool-carrying capacity. Operators can manage hydraulic attachments safely via a standard in-cab pressure release function that depressurizes the system prior to tool changes. To endure the hazards of demolition sites, the machines include track guides, under covers, and a cab built with Level II top and front guarding.
Timeline
August 1, 2025 to July 31, 2026: 15,000 new financed excavators were sold across the U.S.
October 30, 2026: The new KOBELCO models were formally recognized.
The Home Front
This release follows the ongoing industry transition toward Tier 4 Final emissions compliance for heavy construction equipment. It reflects a broader shift in the sector toward minimizing maintenance requirements while adhering to stricter environmental regulations.
Operators can use the integrated KOMEXS telematics system to track machine location and monitor maintenance status in real-time. For daily operations, always utilize the in-cab pressure release function to depressurize hydraulic lines before changing out work attachments.
The takeaway
These new excavators combine specialized demolition boom geometry with simplified emissions technology. Project managers should leverage the 270-degree camera system and 10-inch cab monitor to maintain site visibility and ensure operator safety during high-reach tasks.
