- Product Information-

Features of MT Twin Header
	Low noise Since the cutting style enables the noise level to lower, it is usable in residential area.
	Low shock Due to low shock, and small reaction against the hydraulic excavator side, the excavator body is not spoiled.
	Compact Adoption of the planetary gears for the reducer structure enables the design compact and the handling easy.
	Clean cutting face Due to cutting the rock by picks, the cutting face is finished clean.
	Drum style High cutting capacity is available because of continuous cutting by the drum rotation.
	Multi-purpose It is usable as the cutter with multi-purpose.
	Usable under water The machine with specification usable under water can be made. The rotation drum enable the cutting work easy even in invisible places.
