LIPPMANN INTRODUCES
MASSIVE 5062 JAW CRUSHER
CUDAHY, WI – Lippmann-Milwaukee has introduced a new, massive model 5062 jaw crusher specifically designed for heavy duty, high volume aggregate crushing applications. The crusher is already operating successfully in several leading quarry installations in North America.

To design a machine that delivers this level of capacity and productivity, Lippmann engineers have employed an oversized, heat-treated eccentric shaft forged of special alloy to handle overloads and hard material, extra large radial thrust tapered roller bearings, a huge one-piece cast pitman, and a much heavier, stronger, one-piece stress-relieved frame, says the company.

Robert Turner, Lippmann’s President, stated, “The hydraulic adjustment system we’ve provided on this machine, as standard, will save operators countless hours and allow the setting to be adjusted while crushing. Our customers can expect to increase production rates since they can adjust the jaw as frequently as jaw wear dictates. Consistent setting ensures properly sized material is produced, and a pressure relief system safe guards from uncrushable materials.”

Lippmann’s 5062 employs air springs that maintain pre-set loading on tension rods regardless of setting. Air springs ensure sufficient tension force is maintained to securely hold hydraulic cylinders in position, therefore the Lippmann jaw setting can be adjusted under load unlike other jaw makes, say company officials.

The company’s engineers also state the 5062 offers a true feed opening, better motion, a greater reduction ratio and increased throughput because of a non-choking, forced feeding action that results from a larger eccentric inward and downward movement of the swing jaw. The longer jaw dies create a reduction in nip angle and more positive bite.

Other innovative features of interest include toggle bearing wedges for easy in/out bearing replacement, hardened barrel wear liners to protect the pitman, and replaceable toe wear liners on the swing and stationary jaw.
