New NPK DG-40/40A Demolition Grab for Sale

NPK’s demolition grabs, or sorting grabs / grapples, are designed to meet the high standards of today’s market.  High durability and low maintenance cost make them highly efficient for sorting and recycling construction and demolition waste.

The DG-40/40A demolition & sorting grab is compatible with excavators in the 25-40 metric tons.

Robust and resilient for extended life: Both the frames and the arms of NPK demolition grabs are built with high tension, special wear steel ensuring rigidity and impressive wear resistance.  The large jaw opening and high closing force makes completing any job a breeze.  Grapples can be customized with different styles or widths of arms for specialized applications.  When combined with other heavy duty components, NPK demo grabs deliver superb quality, enhance durability and productivity, and longer life.

360° hydraulic rotation:

Built with powerful hydraulic-rotation motors, NPK sorting grabs provide an operative angle to tackle any application.  A double motor suited for heavy loading applications requiring high torque is standard for all grapple models DG-20 and above.  A single motor option is available upon special request.  The hydraulic motors are protected by a double shock valve and a brake valve protects the internal motor seals and no drain line is needed.  Rotation speed and speed of opening & closing of the arms can easily be adjusted - accessible by an access panel in the swivel top.

Designed for straightforward maintenance: Engineered with fewer hydraulic component connections that are fully encased, the possibility of NPK grapples being damaged and/or leaking is significantly reduced. Hydraulic connections on both sides of the swivel top allow for easy access.  The oversize pins, replaceable bushings with dust seals and heavy duty slewing ring help to increase durability and productivity while reducing down-time.  Easy access to grease ports means that greasing is easy from any angle.
