Telsmith, Mequon, Wis., has introduced the new Telsmith H2238, the latest addition to its Hydra-Jaw Series. The company says the new model is is the result of advanced jaw crusher technology that offers lower operating costs, increased uptime and production capacity, streamlined operation and maintenance and greater safety.
The Hydra-Jaw H2238 addresses reduced operating costs through a hydraulic toggle system which features a heavy-duty hydraulic cylinder that is custom-engineered for crushing applications. The unit’s hydraulic adjustment, relief and clearing systems are designed to eliminate downtime and prevent component damage while also protecting workers from risks typically associated with the operation and maintenance of older jaw crusher models, according to a company press release. 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 company says it is ideally suited to the needs of the portable crushing contractor, the FEA-designed H2238 with a 22-inch-by-38-inch jaw opening is easy to install on wheeled or track-mobile units.
A closer examination of the advanced hydraulic systems in the H2238 starts with the Hydraulic Adjustment, which practically eliminates adjustment downtime, according to Telsmith. Versus the lengthy and often unsafe shim adjustments typical to traditional crushers, the H2238 offers finger-tip controls which are designed to provide easy, frequent and fast adjustments as needed, according to the company. The Hydraulic Overload Relief system prevents crusher damage, downtime and difficult maintenance procedures, the company says, adding that it opens the crusher when internal forces become too high, allowing tramp metal or other non-crushable material to pass and protecting the unit against 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, according to the company. The hydraulics will crush any materials that remain in the chamber and prevent any oversized material from impacting the product belt, the press release states.
