Excavator hydraulic milling cutter EKT 100

rotary

Overview
The patented EK range of chain cutters are one of KEMROC's core products. The concept is expanded with the EKT range of traditional rotary drum cutters supplied as rotary drum cutters without a central cutting chain; conversion kits are available so cutter chains can be fitted later.

Features

• Can be converted to an EK model
• Fast and strong
• Two motors for extra hydraulic power
• Tough, rigid gearbox housing
• Drums supported on robust bearings
• Protection for hydraulic hoses
• Works underwater without need for modifications

Application areas

• Trenching and pipeline work
• Mining of soft to medium hard minerals
• Concrete renovation, profiling, underwater excavations and tunnelling
