McCloskey J50 Overview
The McCloskey J50 is a tracked primary jaw crusher designed for quarry, aggregate, recycled concrete and demanding material-processing applications. Its 50-inch by 29-inch single-toggle jaw, wide material path and mobile configuration make it a strong option for operations requiring dependable primary reduction and jobsite mobility. The J50 is designed for larger feed material, steady material flow and consistent production. Equipment configuration and published specifications can vary by model year, engine package, market and installed options, so confirm serial-specific details before purchase or transport.
Understanding J50 and J50V2 Listings
McCloskey J50 and J50V2 machines on this page because they belong to the same J50 model family. The J50V2 designation appears on certain model years and configurations, while current McCloskey materials generally use the J50 name.
Both designations commonly feature a 50-inch by 29-inch jaw opening, but engine power, transport dimensions, operating weight, feeder configuration and installed options may differ between individual machines. Review each inventory listing for its model year and unit-specific details, and contact US Equipment to confirm the serial-specific configuration.
McCloskey J50 Applications
- An optional prescreen can remove fines before they enter the crushing chamber.
- An overband magnet may be useful when processing reinforced concrete or material containing ferrous metal.
- Dust suppression can help control airborne material where site conditions require it.
- Hopper extensions can support different feeding arrangements.
- Variable-speed conveyor control can help coordinate material flow.
- Quarry, corrugated and multi-tooth jaw profiles allow the wear package to be matched more closely to the application.
Confirm installed equipment on each new or used machine instead of assuming every J50 includes these options.
Transporting a McCloskey J50
Published transport dimensions and weight describe a specific OEM configuration. Actual transport requirements can change by model year and with the magnet, side conveyor, prescreen, bogie and other installed equipment.
Before scheduling transportation:
- Confirm the machine's serial-specific weight and dimensions.
- Identify the installed magnet, side conveyor, prescreen and bogie configuration.
- Confirm loading and unloading requirements.
- Have the carrier evaluate trailer selection, total loaded dimensions and route requirements.
- Verify permits and restrictions for every state on the route.
US Equipment can help coordinate serial-specific transport information and heavy-haul planning.
J50 Maintenance and Used-Machine Inspection
Maintenance intervals must follow the operator manual for the specific machine. A practical inspection program should include the following areas.
Pre-shift checks
- Engine, hydraulic and coolant fluid levels
- Visible leaks and damaged hoses
- Guards, emergency stops and safety devices
- Jaw dies, cheek plates and visible wear
- Feeder condition and material buildup
- Conveyor belts, skirting, rollers and tracking
- Tracks and undercarriage condition
- Magnet and dust-suppression equipment, when installed
Wear management
Jaw-die profile and manganese selection should match the feed material and abrasiveness. Inspect wear patterns regularly rather than waiting for poor reduction or reduced production to identify a problem.
Scheduled service
Follow the serial-specific manual for lubrication, filters, fluids, belt adjustments and component inspection. Record completed maintenance and recurring faults so wear and downtime trends can be identified.
Evaluating a used J50
Ask for:
- Verified meter hours
- Engine and emissions-system information
- Service and repair history
- Jaw-die and cheek-plate condition
- Toggle, wedge and jaw-adjustment condition
- Feeder and pan-feeder condition
- McCloskey J50 model description
- Conveyor and skirting condition
- Hydraulic leaks and operating pressures
- Track and undercarriage condition
- Installed options
- A cold start, operational demonstration and current inspection
McCloskey J45 vs. J50 vs. J6
The three jaw crushers serve different application and transport needs. Published figures should be confirmed for the specific model year and configuration.
McCloskey J45
Jaw opening: 45 x 27 in
Published engine: Up to 350 hp
Main conveyor: 42 in
Best-fit consideration: A smaller, lighter universal jaw for operations that do not require the J50 opening.
McCloskey J50
Jaw opening: 50 x 29 in
Published engine: Up to 375 hp
Main conveyor: 48 in
Best-fit consideration: A wider jaw opening for larger feed and production-focused primary crushing.
McCloskey J6
Jaw opening: 48 x 34 in
Published engine: 510-536 hp
Main conveyor: 55 in
Best-fit consideration: A deeper crushing chamber and heavier configuration for demanding hard-rock applications.
The best choice cannot be determined from jaw dimensions alone. Feed material, desired product, loader size, mobility requirements and downstream capacity should all be reviewed.

Frequently Asked Questions
What size is the McCloskey J50 jaw opening?
The published J50 feed opening is 50 inches by 29 inches.
How much does a McCloskey J50 weigh?
McCloskey's current feature sheet lists a published transport weight of 130,702 lb with a magnet and side conveyor. Actual weight varies by year and configuration, so obtain serial-specific transport information.
What are the J50 transport dimensions?
The current feature sheet lists approximately 47 ft 5.9 in long, 8 ft 2.5 in wide and 11 ft 1.8 in high. Other published J50 configurations differ, so verify the individual machine.
What materials can a J50 process?
Common applications include quarry rock, aggregate, sand and gravel, recycled concrete, asphalt and construction or demolition material. Machine setup and wear components should be matched to the material.
How many tons per hour can a McCloskey J50 produce?
There is no single guaranteed production rate for every application. Output depends on feed gradation, hardness, moisture, closed-side setting, jaw condition, loading consistency and downstream equipment. US Equipment should evaluate the proposed application before providing an estimate.
What is the difference between the J45 and J50?
The J50 has a larger published jaw opening and wider main conveyor. It is generally considered when larger feed or greater primary-crushing capacity is required. The J45 may suit operations needing a smaller and lighter machine.
What should I inspect before buying a used J50?
Verify the hours, serial number, service history, engine configuration, jaw wear, feeder, conveyors, hydraulics, tracks and installed options. Request a cold start, operating demonstration and current inspection.
Are parts and service available for the McCloskey J50?
US Equipment supports McCloskey crushers with equipment service, wear parts, replacement components and field support across its service territory. Contact the parts or service team with the model and serial number.
