Pegson AX815 Premiertrak 26×44 Jaw Crusher: The Enduring Workhorse of Primary Crushing
In the demanding world of aggregate production, mining, and recycling, primary jaw crushers form the critical first line of attack against raw feed material. Amongst the stalwarts that have earned a reputation for robust performance and unwavering reliability stands the Pegson AX815 Premiertrak 26×44 Jaw Crusher. This machine represents a significant chapter in Terex Pegson’s history (now integrated into Terex Materials Processing), embodying engineering principles focused on productivity, durability, and operational efficiency that continue to make it a sought-after asset on job sites worldwide.
Engineered for Toughness and Output
At its core lies a formidable single-toggle jaw crusher design featuring a massive 1100mm x 700mm (44″ x 28″) feed opening – a specification directly referenced in its “26×44” designation (where dimensions are often approximated in inches). This substantial gape allows it to readily accept large feed material directly from excavators or wheel loaders, minimizing pre-screening requirements and maximizing primary processing efficiency.
Robust Construction: The crusher frame is built from heavy-duty welded steel plate construction, designed to withstand the immense stresses generated during crushing hard rock like granite or basalt. Critical components utilize high-grade materials ensuring longevity under continuous operation.
High-Performance Chamber: The fixed jaw configuration provides excellent nip angles for efficient grip on feed material as it enters the chamber. The aggressive swing jaw profile maximizes throughput potential while promoting optimal particle shape reduction.
Powerful Drive System: Driven typically by a Caterpillar C9 ACERT Tier III compliant diesel engine generating approximately 261 kW (350 hp), the AX815 delivers ample power to tackle demanding applications efficiently. This engine provides reliable starting in harsh conditions and sufficient torque for peak crushing loads.
Hydraulic Adjustment & Overload Protection: A key feature enhancing operational flexibility is the hydraulic adjustment system for setting the closed side setting (CSS). Operators can quickly and safely adjust output product size without manual intervention using remote controls – crucial for adapting to changing feed materials or product specifications.
Crucially integrated with this is the hydraulic release system acting as overload protection. Should an uncrushable object enter the chamber (like tramp metal), hydraulic pressure builds until it triggers an automatic release mechanism that opens the jaw wider than usual to eject the obstruction before safely resetting itself – protecting vital components from
