New “J” Series Crusher added to McCloskey Line

Machine diagnostics can drastically reduce maintenance downtime

McCloskey International has introduced a new addition to its "J" series of crushers, with some unique features that make the J44 Jaw Crusher a standout in its category.

The J44 main conveyor has a large stockpile capacity (12’ – 11") as a result of the standard extended 42" conveyor, and the large gap between crusher discharge and the main conveyor feedboot. The folding Hardox hopper is mounted over the vibrating feeder with integral pre-screen. Further, the feeder rate can be regulated manually or automatically by the load sensing jaw.

The J44 has an I-beam plate fabricated chassis construction, and features a true 44" x 26" (1118 mm x 650 mm) single toggle jaw with reversible hydrostatic drive and jaw plates as well as fully hydraulic closed size setting adjust capability.

Ease of maintenance is a strong advantage for the J44. The Control Panel is user-friendly and has machine diagnostics that can drastically reduce downtime for maintenance. Adding to the ease of maintaining a J44, the conveyor is easily removable as it raises and lowers hydraulically and the CAT C9 ACERT engine has all round access.

With the advantage of the efficiency of McCloskey’s integrated hydraulics, better fuel economy is realized and the J44 can be on-site and operational in a matter of minutes with its folding hoppers and conveyers. Easy to move from site to site, the J44 has transport dimensions of 11’-1.8" (3.4 m) high and 47’ - 5.5" (14.465 m) long, and weighs in at 88,184 lbs. (40,000 kgs).

With additional options like a water pump and dust suppression system, hopper extensions, an overband magnet or Crusher Deflector Plate, as well as robust standard safety features, the J44 is high performance and productive.
