Multiprocessor M-20 K/S/G

More power – more production

The NPK® Multi Processor is an efficient solution for concrete, steel and rebar processing, building and bridge demolition and recycling. The jaws can be exchanged on-site which saves costs. The processor is manufactured from high strength, abrasion-resistant steel and the cylinder rods are fully protected.

The Multi Processor is designed in such a way that whenever the jaws meet resistance, the hydraulic booster is automatically activated. The pressure intensifier system has a relatively low oil flow; which produces faster cycle times and more crushing strength when compared to competitive attachments without a booster system. Additionally, other excavators functions remain uninfluenced by this system. The integral booster reduces the total weight of the attachment, which allows a compact body design and affords ease of maintenance.

Features

• On-site versatility is optimized by the availability of interchangeable jaw­s.
• Only NPK® offers an exclusive integrated booster system that automatically activates when the jaws meet resistance.
• Efficient solution for concrete, steel and rebar processing, building and bridge demolition, and recycling.
• Manufactured from high-strength, abrasion-resistant steel.
• Reinforced shield protects cylinder rods.
• Cost effective: far more economical than buying three different attachments for three different applications.
• Full 360° power rotation provides an effective angle of attack for any job wherever the location.
• No additional pressure reduction is required in the hydraulic system.
• Fast opening/closing times.
• Reliable construction.
