Frequently Asked Questions
What is the Komplet K-JC 503 mini jaw crusher used for?
The Komplet K-JC 503 is a compact, tracked mini jaw crusher used to process concrete, softer stone, brick, cold asphalt, and natural rock directly on small or tight-access job sites. It is designed for contractors, landscapers, hardscapers, pool and basement waterproofing crews, and small recyclers who need on-site crushing without the size, weight, or capital cost of a larger machine. By turning demolition and excavation waste into reusable aggregate at the job site, the K-JC 503 helps eliminate haul-away costs and reduce landfill fees.
How small is the K-JC 503 and where can it fit?
The K-JC 503 is Komplet America’s most compact tracked jaw crusher. It weighs 7,496 lbs and measures only 5 feet wide and 9 feet 8 inches long in transport configuration — small enough to be towed behind a standard pickup truck and to fit through residential gates, basement access points, and other tight openings that larger crushers cannot reach. Its rubber tracks let it self-propel into position without a crane or wheel loader.
What is the production capacity of the K-JC 503?
The K-JC 503 produces up to 34 US tons per hour, depending on material type, input size, and output setting. It uses a 19 by 12 inch single-toggle jaw inlet powered by a 25 hp Tier 4 Final diesel engine. For best results, material should be pre-processed to roughly 10 inches minus before entering the jaw. Output size is hydraulically adjustable from 3/4 inch to 3-1/4 inch, allowing operators to dial in the exact end product needed for each job.
What materials can the K-JC 503 crush?
The K-JC 503 handles hard, brittle materials including concrete, brick, softer stone, cold asphalt, and other natural rock. It is not recommended for soft, gummy, or fibrous materials like clay or wood. For mixed C&D waste containing wood, drywall, or softer materials, the Komplet Krokodile PLUS slow-speed shredder is the better starting point. The 19 by 12 inch jaw inlet means feed material should be sized to approximately 10 inches minus before crushing.
How does the K-JC 503 compare to the K-JC 704 PLUS?
The K-JC 503 is significantly smaller and lighter than the K-JC 704 PLUS. The 503 has a 19 × 12 inch jaw, produces up to 34 tph, and weighs 7,496 lbs — small enough to tow behind a pickup truck. The 704 PLUS has a 27 × 16 inch jaw, produces up to 90 tph, and weighs 26,455 lbs. The 503 is the right choice for landscapers, hardscapers, pool and basement crews, and any contractor working in tight residential or urban environments. The 704 PLUS suits higher-volume operations, yard-based recycling, and rental fleets. Both are tracked, portable, and serviced through Komplet America’s New Jersey warehouse.
