Excavator cold planer EX 70 HD

for asphaltfor concrete

Overview
The KEMROC EX Patch Planers are precision attachments designed for milling asphalt, concrete, bricks, natural stone and similar surfaces. They provide accurate depth control (mechanical or hydraulic), high-torque modifiable hydraulic motors, low vibration operation and integrated water jets with optional vacuum dust extraction ports. EX planers can operate on horizontal, vertical, inclined and overhead surfaces, achieving milling depths up to 190 millimetres and delivering smooth cut edges with fine-grained cut material output.

Benefits

• A rigid support frame with wear resistant slides
• High torque, modifiable hydraulic motor
• Robust housing with low vibration
• Accurate depth control (mechanical or hydraulic)
• Smooth cut edges and fine-grained cut material
• Integrated water jets for dust control; connections for vacuum dust extraction optional

Technical description
The EX range is engineered for versatility and durability to handle the hardest asphalt and concrete as well as masonry and natural stone. Depth control options allow precise milling up to 190 mm. The high-torque, low-vibration design improves surface finish and reduces tool and carrier wear. Water jets support dust suppression and an optional dust suction port can be used for vacuum extraction. The planers are intended for applications such as road repair, house connections, removal of contaminated concrete, tunnel renovation, plaster removal and other renovation/demolition tasks.
