OSAs multifunction dual-cylinder shear is functional and versatile, able to perform a wide range of demolition tasks. Its 360° rotation allows for fast, accurate and efficient positioning of the jaw. Ideal for excavators with long arms and those not equipped with rotation device. Key features include:

1. Two hydraulic cylinders and 360° rotation
2. Hardox and Weldox structure
3. Regenerative installation available.

The MC series is by far the most universal attachment on the market today. The MC series can satisfy every type of demolition application due to the fact the heads are interchangeable so the unit can serve as a, Steel Sheer, Concrete Cutter or Concrete Pulveriser. This unit is the most sort after product globally.

The MC Series of Multifunction Rotating Shear have been manufactured with HARDOX 400 to resist wear and tear and they have a regenerative circuit for a fast opening and closing of the jaws. Hydraulic or Mechanical rotation (360°) gives precise positioning of the Cutting/crushing head in all working conditions. Concrete & Steel structure are demolished, pulverized and steel reinforcements are separated and compressed in minimal time. This efficient procedure results in a considerable reduction of dumping and transportation costs.

The wide jaws, large opening and quick closing time of the MC Series is another advantage giving you a high yield rate in the shortest time possible making the MC the most efficient and cost effective Multifunction attachment on the market.

The fully shielded cylinders of the MC are designed and built by OSA, this innovative new design cylinder along with the geometric design of the MC produces up to 430 ton of closing pressure, making the MC the most powerful Multifunction Rotating Shear/Pulveriser/Crusher on the market.
