It produces up to 160 US tons per hour from medium-to-hard rock, reinforced concrete, asphalt, and demolition material, making it the right choice for rock quarries, civil and road contractors, high-volume recycling facilities, and rental fleets. At 49,600 lbs, it delivers quarry-scale output while remaining transportable on a standard heavy-haul flatbed.

Frequently Asked Questions
What is the Komplet K-JC 805 mobile jaw crusher used for?
The Komplet K-JC 805 is Komplet America’s largest compact mobile jaw crusher, used to crush medium-to-hard rock, reinforced concrete, asphalt, and demolition material at quarry-scale volumes. It is built for rock quarries, site contractors, civil and road/bridge contractors, municipalities, and recycling facilities that need higher production than the K-JC 704 PLUS but still want the mobility and quick set-up of a compact, tracked machine. It is also commonly used as a primary crusher feeding a secondary K-IC 70 impact crusher or Kompatto screener for spec-grade aggregate production.
How does the K-JC 805 compare to the K-JC 704 PLUS?
The K-JC 805 is a significantly larger machine. The 805 has a 31 by 21 inch jaw, produces up to 160 tph, runs a 130 hp engine, and weighs 49,600 lbs. The K-JC 704 PLUS has a 27 by 16 inch jaw, produces up to 90 tph, runs a 74 hp engine, and weighs 26,455 lbs. The 704 PLUS is Komplet America’s best-selling crusher and the right choice for most contractor and C&D recycling operations. The K-JC 805 is the right choice when production volume, larger feed material, or quarry-scale operation justifies the bigger machine. Both are tracked, mobile, and serviced through Komplet America’s New Jersey warehouse.
What is the production capacity of the K-JC 805?
The K-JC 805 produces up to 160 US tons per hour, depending on material type, input size, and output setting. It is the highest-capacity unit in Komplet America’s compact crusher lineup. The 31 by 21 inch single-toggle jaw inlet and 130 hp Tier 4 Final diesel engine deliver throughput suitable for rock quarry operations and high-volume C&D recycling. Output is hydraulically adjustable from approximately 1.2 inches to 4.7 inches.
What materials can the K-JC 805 crush?
The K-JC 805 handles a wide range of hard, abrasive materials including granite, basalt, limestone, sandstone, virgin quarry rock, reinforced concrete, asphalt, and dense demolition rubble. The reverse jaw function clears sticky material and uncrushable contaminants, making the machine more tolerant of mixed C&D feed than crushers without that feature. The 31 by 21 inch inlet allows larger feed material than any other jaw crusher in the Komplet lineup, reducing the amount of pre-processing required from a hydraulic breaker or excavator.
How is the K-JC 805 transported between job sites?
The K-JC 805 weighs 49,600 lbs and is transported by heavy-haul flatbed for domestic and long-distance moves. It self-propels on steel tracks with bolted-on rubber pads — designed to handle hard quarry surfaces while also protecting yard surfaces and trailer decks during transport — for repositioning around the job site or yard. On-site, the K-JC 805 sets up quickly and is operated entirely by wireless remote control. For specific transport requirements — permitting, axle loads, route restrictions — Komplet America’s team can advise on regional logistics.
What standard features does the K-JC 805 include?
The K-JC 805 includes a side conveyor for finished product discharge, magnetic separation for rebar and ferrous metal removal, hydraulically adjustable jaw setting, a reverse jaw function for sticky or uncrushable applications, wireless remote control of all functions, and Komplet Connect remote monitoring. The base price of $454,366.25 includes the base unit, magnetic attachment, and side conveyor — three components that are options or add-ons on many comparable mobile jaw crushers.
