NPK steel shears

Powerful and efficient, NPK steel shears are an excellent choice for increasing productivity and reducing costs in metalworking and demolition.

NPK steel shears are designed for the efficient demolition of steel structures. The design and shape of all models help to improve visibility during use. The high cutting force and the integrated standard power-boosting system make each model one of the most efficient and powerful shears in its class. The shears can be used to cut all types of steel, such as reinforcing bars or steel beams (e.g. H-beams).

The special design of the main bolt prevents the frame from opening or becoming undesirably deformed. This ensures that the distance between the jaws and the blades remains constant, preventing material from becoming trapped between the blades. Thanks to this unique design, even thin steel sheets can be cut without any problems.

The NPK steel shears have been developed to meet the market’s need for steel shears for mini-excavators. As part of the development of the grapples, a new power-boosting system has also been created. The power-boosting unit is integrated into the cylinder, and the number of moving parts has been reduced.
