Kinshofer’s MQP boasts jaw dropping change-out times

MQP jaw

Kinshofer’s Multi-Quick Processors (MQP) allows demolition and recycling industry contractors to use one attachment with several jaw sets instead of several tools for different applications.

Contractors are able to choose from six to eight jaw sets, depending on which of the four MQP models they choose, including dedicated concrete, steel or tank jaws, as well as combination and specialty jaws.

“We know that by enabling contractors to complete more jobs with fewer pieces of equipment, we boost their profitability and expand their businesses,” said Francois Martin, general manager of Kinshofer North America. “The Kinshofer Multi-Quick Processor is the ultimate tool to do just that. Like all of our products, the processor helps customers do more with less.”

Kinshofer’s MQP features the company’s DemaPower cylinder technology. The cylinder uses four chambers instead of two, resulting in 20 per cent more surface area within the cylinder. That allows the MQP to exert up to 25 per cent more power from a smaller attachment.

This means that a section of concrete that may take an attachment five or six bites to break through only takes the MQP one or two. Higher power in a smaller tool also improves efficiency and performance for high-reach demolition.

For high-reach demolition, contractors can use a smaller carrier with a higher-powered attachment. Due to the attachment’s light weight and cylinder technology, fuel efficiency is improved while the excavator arm is fully extended.

Kinshofer’s double-acting speed valves and cylinder technology also boost the MQP’s jaw closing and opening speed, generating cycle times as fast as 5 seconds. With attachment’s fast cycle times and high power, contractors can complete jobs as much as 20 per cent faster, improving return on investment.

Thanks to the DemaLink system, contractors are also able to change the MQP faster. Operators only need to manually remove one pin from the attachment during change-out. The other two pins are removed hydraulically from the safety of the cab. This not only removes the hassle of pounding out three pins, but also virtually eliminates the danger of the jaw falling and injuring a worker after the last pin is removed. In addition, DemaLink allows two people, or a single skilled operator, to switch out jaws in minutes and get back to work quickly.


Kinshofer’s jaw offering includes the combi jaw for primary demolition and a mixture of concrete and steel; the demolition jaw for primary demolition of heavy concrete structures; the pulverizer jaw for primary or secondary demolition, pulverizing concrete during or after the job, as well as some steel cutting; the steel jaw for primary and secondary demolition of steel structures and scrap; the tank shear jaw for primary and secondary demolition, including demolition of tanks and cutting steel plates; and the universal jaw for primary and secondary demolition of concrete decks.

The MQP steel and combi jaws feature the company’s DemaGuide system, which uses a guide plate to provide additional stability at the pivot point. The extra stability means greater cutting efficiency and precision.

The cylinder also features a trunnion design, ensuring compactness, a better centre of gravity and an optimal closing force curve. Once the shims show signs of wear, maintenance crews can adjust the jaw tolerance by tightening the main pin. The shims are replaceable in a few steps, including loosening the main pin nut, taking the main pin out and removing the jaw. This design also reduces the need for contractors to buy additional bushings and pins as the components may be re-used when replacing the shims.

Twin rotation motors

Kinshofer reinforces the MQP with twin rotation motors. This boosts rotation power and reduces the risk of the attachment shifting or rotating on its own, causing potentially dangerous situations. The MQP also includes a safety system that reduces the risk of dangerously high pressures within the rod cylinder.

To reduce replacement costs and service downtime, Kinshofer manufactures all wear parts for easy onsite replacements and exchanges across jaw types. In addition to offering exchangeable cutting edges, Kinshofer features crusher attachment teeth that can be quickly replaced on site. The ease of replacement combined with Kinshofer’s performance-enhancing features delivers a low cost of ownership and fast return on investment.

Additionally, the company designs the tool’s oil distributor to include an extra channel to allow for water spray or grease systems.

The MQP also includes features to prevent carrier damage in the event of a rotation motor breaking. Engineers designed the tool with rotation circuit filters to catch small pieces of metal that can break off rotation motors and travel through the lines into the valve and then the tank.

In addition to jaws focused on demolition and recycling applications, Kinshofer has developed a MQP-Wood jaw for forestry applications. The manufacturer is also developing an MQP-Extreme jaw for heavily reinforced or thick concrete.

The jaw features additional ripper tools for better concrete penetration. The MQP-E boasts higher closing force than any other multi-quick processor jaw in the world.  The Kinshofer MQP is suitable for 18 to 65-ton carriers.
