JAW CRUSHER: Longer wear life, easy maintenance for McLanahan’s Universal model

HOLLIDAYSBURG, Pennsylvania – McLanahan’s line of Universal jaw crushers has undergone a series of design updates. Based on customer feedback and years of applications expertise, these improvements have been engineered to make everything from installation to maintenance a safer, simpler and smarter process.

This new Universal jaw crusher design features replaceable upper and lower stationary jaw die clamp plates, which are lighter, making it easier to install, replace and secure the die. Operators no longer have to rely on heavy key wedge or heel plate style sideliners to lock the dies in place. Additionally, all clamp plates are interchangeable if one side or top/bottom experiences more wear.

Sideliners have been redesigned as three cheek plates per side (top, middle and bottom). This allows liners in high wear areas to be replaced independently of other liners.

Maintenance is simplified by the inclusion of several replaceable parts, including the barrel liner, the smash plate, and a bolt-in pitman toe for easy replacement. Maintenance is even easier with the new self-aligning locking wedges that are adjusted from the rear of the crusher. The redesigned jaw crushers also feature a safety pin that will lock the pitman in a closed position when maintenance is being performed.

Finally, Universal jaw crushers are now have frames that are engineered to allow for infinite possibilities when it comes to mounting feet design and customization. With custom feet, the crusher can be tipped forward, as well as located higher and lower or forward and backward from obstructions in an existing or new structure that would have normally made installation impossible.
