It is an attachment that installs on the tip of a hydraulic excavator.It is able to cut and crush the the concrete structures including steel bars and rebar with two large blades (jaws). It is better to be light for safe work, and more efficient to crush the reinforced concrete structures with a large opening width. The Guzzila DS cutter series realizes the industry's top class cutting power and weight saving. ① The original shape of the jaws with blade can be sharply cut into the object and can be improved the work efficiency. ② To realize weight reduction of jaws and to improve durability at the same time, we manufacture the jaws by cutting out the abrasion resistant steel plate.③To realize the maximum opening width , we adopt the homemade thick and short hydraulic cylinders.
