The new Hydra-Jaw H2238 (as well as the previously introduced H2550) jaw crusher has a hydraulic toggle system with a heavy-duty hydraulic cylinder custom-engineered for crushing applications. The unit’s hydraulic adjustment, relief and clearing systems eliminate downtime, component damage, and protects workers from risks associated with the operation and maintenance of older jaw crusher models. The H2238 is engineered with a Pitman Lockout Pin that locks the Pitman in the forward position, allowing the toggle to be retracted and lowered away for maintenance in one safe, simple operation. The FEA-designed H2238 (with a 22-in x 38-in jaw opening) is easy to install on wheeled or track-mobile units. The hydraulic system in the H2238 helps reduce adjustment downtime. Versus the shim adjustments typical to traditional crushers, the crusher has finger-tip controls which allow easy, frequent and fast adjustments as needed. The Hydraulic Overload Relief system prevents crusher damage, downtime and difficult maintenance procedures by opening the crusher when internal forces become too high, allowing tramp metal or other non-crushable material to pass, and protecting the unit against costly component failure. After relief, the system automatically returns the crusher to the previous setting for continued crushing. The Hydraulic Chamber Clearing allows the operator to safely and easily clear the crusher, and resume operation in minutes. The hydraulics will crush any materials that remain in the chamber and prevent any oversized material from impacting the product belt. The H2238 also has inexpensive replaceable toggle ends; a toggle tensioning system that eliminates the need to adjust springs when changing the settings; jaw dies that are interchangeable between the swing and stationary jaws and are reversible from top to bottom; an impact plate that protects the pitman from wear; and grease lines plumbed to a central distribution point for quick maintenance access. www.telsmith.com
