| Automatic Blockage Clearance |
|
|
 |
-
This industry unique feature is an exclusively designed control system by Screen Machine Industries.
-
Jaw can be opened with the remote control to clear a blockage. Upon clearing the jaw will return automatically to the previously set limit.
|
| Automatic Tramp Iron Relief |
|
|
 |
- State of the Art Tramp Iron Relief System protects the jaw when an uncrushable enters the jaw chamber. Jaw automatically returns to previously set limit after the tramp iron has cleared.

The Value of a Universal Engineering Jaw Crusher
With its overhead eccentric principal, Universal Engineer Corp. brought double crushing action to the rock producers of America several decades ago and made crushing a profitable business. Universal’s patent in 1906 was the first overhead eccentric, single toggle jaw crusher. Universal’s overhead eccentric jaw crushers last longer and crush longer because they are constructed from top quality materials to a field proven design. These crushers are built with brute strength for rugged service in a tough industry. There are many attempted copies of the Universal overhead eccentric jaw crushers, but few have challenged Universal’s superiority. Daily reports from owners of Universal jaw crushers, some of them in service for 70 years and still going strong, lend proof to Universal’s superiority and durability in the industry.

The Value of a Caterpillar® Undercarriage
Simply stated...many manufacturers of moving undercarriage components, including link assemblies, rollers, idlers & sprockets, (which represents up to 75% of the cost of the completed lower arrangement) do not have the stringent processes in place that yield quality components. Varying hardness levels, material specifications & manufacturing processes will often produce an inferior component leading to unpredictable wear rates, service points, & untimely destruction. The result is increased & unscheduled downtime causing increased operating costs and lower profits. Caterpillar® moving undercarriage components all go through special heat treating processes which provide consistent surface hardness, superior hardened depth & core hardness levels.
The resultant component, be it a link, roller, sprocket or idler, have a distinct metallurigical advantage which yields superior wear resistance, strength & durability for long term service life. Screen Machine Industries, Inc. is committed to utilizing name brands that deliver maximum performance at the lowest operating costs per hour.
