KINSHOFER has widened its range with the launch of the D-Series grapples
KINSHOFER is now offering its D-Series grapples with a new light, compact and flexible shell, ideal for sorting and demolition. The attachments feature 360° rotation for precise positioning to give construction, demolition and recycling contractors optimal control when grabbing materials. The D-series grapples are available for mini excavators weighing from 2tonnes to heavy-duty excavators weighing up to 80tonnes.

The firm says that the D-Series offers jobsite versatility to customers. The units allow excavator operators to grab, sort and move a variety of materials. The design incorporates multiple features said to reduce maintenance and extend service life.

Conventional heavy-duty hydraulic cylinders with hydraulic damping protection power the D-Series, while KINSHOFER’s patented HPXdrive powers the D04HPX, D06HPX, D09HPX and D35HPX. The cylinderless HPXdrive system provides constant closing force compared to competitive grapples and reducing overall cost of ownership by a claimed 50% compared to conventional models.

The design of the D-Series offers a compact footprint, ideal for working in tight areas, such as urban demolition sites. Meanwhile, the grapple’s robust Delta-box frame provides durability and reliability for demanding applications such as quarries and large-scale demolition. In addition, the units have dust-proof axle bearing points to prevent damage from dust and debris.     

To prevent overloading, the D-series is equipped with pressure relief valves as well as a perforated shell design that filters fine dust and gravel while keeping larger pieces in the shells. If an operator overworks the grapple, the innovative shells flex to avoid structural damage. The grapples also feature a non-return valve to keep the load secured even if a pressure drop occurs, ensuring safe operation.

For handling small-grained bulk material, such as sand and gravel, KINSHOFER offers side plates. Customers can also equip the grapples with a compression rail adapter, which allows the attachment to handle and position delicate materials, such as kerbstones, without damaging them.

The D-Series includes a fully enclosed, heavy-duty slewing ring with full rotation for precise positioning. The grapples feature exchangeable cutting edges, manufactured with 500 HB steel for exceptional longevity. The cutting edge is also reversible to further extend its service life.
