G Series Secondary Crushers Features that are specially designed for maximum productivity
NPK's secondary Concrete Crushers are designed to effectively handle any secondary demolition and recycling of concrete. NPK crushers easily crush through reinforced concrete

which allows material to be separated and recycled, and simultaneously, permits easier handling of material.

Faster, more efficient separation of concrete and steel rebar
Powerful crushing force increases as jaws meet resistance, and the exclusive NPK cylinder intensifier converts flow to pressure.

Designed for performance
Abrasion resistant, high strength, alloy steel teeth allow decreased wear and increased durability. Tooth configuration facilitates separation of steel from concrete for maximum productivity. These teeth are now bolt-on replaceable on all J models for maximum efficiency. In addition, the Model G-30JR now comes with full 360 degree power rotation for maximum versatility.

Maximum crushing force with more efficiency
Competitive cylinder systems need larger cylinders to equal the force developed by the more compact NPK intensifier system.

Shortest cycle time on the job
NPK intensifier system provides faster cycle times compared to competitive units that use large cylinders that require large amounts of flow to produce and equal amount of productivity.

Replaceable rebar cutter blades
Cutting-torch operations are eliminated by high-strength steel jaw blades that slice through rebar.

The NPK advantage in parts and service
Over 280 NPK distributor outlets are professionally staffed and conveniently located to serve your needs. Just one of the many reasons that have made NPK the leader in boom-mounted attachments.
