KINSHOFER Hydraulic Mobile Shears Feature Industry-Leading
Power-to-Weight Ratio and Cycle Times

KINSHOFER, one of the world’s leading sources of high-quality excavator and loader crane attachments, introduces the DXS Series of hydraulic mobile excavator shears. The line features industry-leading in its size class power-to-weight ratios, jaw opening sizes, cycle times and hydraulic efficiency. The attachment series, which debuts with the DXS-50 model, is ideal for scrap processing, tire recycling and demolition.

“We designed the DXS Series to enhance contractors’ productivity and ROI,” said Francois Martin, KINSHOFER North America general manager. “Traditionally, more power means a larger cylinder, which results in a bigger, heavier shear and, often, a larger machine. The DXS-50 has the same-sized cylinder as shears in the same weight class, but with 20% more power, allowing our customers to achieve higher performance without investing in larger carriers. This saves them money up front while improving their ROI with the attachment’s production-boosting qualities.”

KINSHOFER’s DemaPower™ cylinder technology gives the DXS-50 the same power as shears 2 sizes larger. The cylinder uses 4 chambers instead of the 2 found in other shears, resulting in 20% more surface area within the cylinder. That allows the DXS Series to exert up to 25% more power from a smaller attachment, resulting in the best power-to-weight ratio in its size class. The 4,500 kg DXS-50 features a closing force of 10,700 kN, compared to 8,210 kN from its 4,100 kg predecessor, the DRS-45.

Like the DRS-45, the DXS-50 is suited for 23 t to 32 t carriers when boom mounted, and 29 t to 45 t carriers when stick mounted. This means contractors can achieve a closing force equivalent to shears 2 sizes up. In addition, the cylinder technology allowed KINSHOFER to design the DXS-50 with a jaw opening 74 cm wide and 78 cm deep – larger than any other shear in its weight class, as well as some larger models.

The DXS-50 reduces carrier fuel consumption by up to 20% compared to competitive shear models. The attachment’s efficient design allows it to function normally when the carrier is set in economy mode, achieving the same performance as a competitive shear on an excavator running at full throttle.

The DXS-50’s high power-to-weight ratio makes the attachment ideal for top-down demolition, both because contractors can use smaller carriers and because the attachment’s light weight and superior cylinder technology improve fuel efficiency while the excavator arm is fully extended. In addition, KINSHOFER designed the attachment with a narrow frame to allow operators to better see their work.

KINSHOFER’s double-acting speed valves and innovative cylinder technology also give the DXS-50 superior jaw closing and opening speeds. The cycle time is as fast as 5.5 seconds, 50% faster than any model in the attachment’s weight class. Competitive models use a single-acting speed valve that allows only for a fast opening speed or closing speed, not both. The DXS-50’s fast cycle times, coupled with its high power and low fuel consumption, allow contractors to complete jobs faster at a lower cost, improving ROI.

Rotation-equipped models feature 360° continuous rotation on an oversized slewing ring to bear high forces, shock loads and bending. The rotation model also includes heavy-duty motors for maximum rotation torque.

KINSHOFER designs the attachment to minimize downtime, with no protruding components that could become damaged. Convenient service openings give contractors fast access to shear hoses and hydraulics. The DXS-50 also features a piercing tip that can be welded again and replaced.
