KEMROC KDS 50 HD Diamond Saw in Underground Pipe Demolition Project.
Liebherr Excavator with KEMROC KDS 50 HD I Cutting Pipes in Germany.
The Challenge: Cutting Pipes Where Other Solutions Can’t Reach
Urban infrastructure renewal often presents unique challenges, especially when access is restricted and precision is essential. In Munich city centre, Germany, a contractor faced exactly this situation while removing large grey cast-iron pipelines installed within a narrow trench. Conventional methods used for building demolition, concrete demolition, and concrete removal were impractical due to the confined working area and the need for controlled, accurate cutting.
The Solution: KEMROC KDS 50 HD on a Liebherr Excavator
To overcome these challenges, the contractor selected the KEMROC KDS 50 HD Diamond Saw mounted on a Liebherr excavator. This excavator saw attachment enabled safe, efficient and highly precise cutting directly inside the trench without unnecessary excavation or disruption.
Project Performance That Speaks for Itself
The project involved cutting approximately 10 linear metres of grey cast-iron pipe with a 25 mm wall thickness. Equipped with a 1,000 mm diamond saw blade for steel, the KEMROC KDS 50 HD diamond saw achieved a cutting depth of 600 mm while maintaining an average productivity of 2 metres per hour. Water was available throughout the operation to ensure optimum blade cooling and dust suppression.
Why Contractors Chose KEMROC?
The greatest challenge was accessibility. The pipelines were positioned inside a narrow excavation where traditional wire saw concrete systems or handheld equipment would have been difficult to operate safely and efficiently. By using the KEMROC diamond saw, the operator maintained full control from the excavator cab while producing accurate vertical cuts.
The contractor selected the KEMROC KDS 50 HD because of its higher productivity and its ability to work efficiently in confined spaces. During the entire one-week project, only one diamond saw blade was consumed, demonstrating excellent durability and low operating costs.
The KEMROC Advantage for Modern Demolition Projects
Whether for concrete cutting, concrete sawing, selective demolition, building demolition, or demanding infrastructure projects, the KEMROC KDS series delivers a powerful alternative to conventional cutting technologies. Compatible with diamond saw blades for natural stone, granite, concrete and reinforced concrete, the attachment provides controlled cutting with minimal vibration and maximum operator safety.
For contractors looking for a concrete cutting saw, concrete wall saw, demolition saw, rock saw excavator, or a versatile excavator saw attachment, the KEMROC KDS 50 HD diamond saw offers greater productivity, lower operating costs, and precision where conventional methods reach their limits.
