Skid Steer Asphalt Crusher: WIG 72 Output Size, Flow and Jams

The WIG 72 is a skid steer asphalt crusher that turns broken asphalt into a rough base material you can reuse on site.

How fine does the WIG 72 asphalt crusher crush?

The WIG 72 crushes material to about two inches or smaller. What comes out is a rough base material, not a finished small gravel you could grade smooth on a driveway.

Neither the WIG 72 nor the Raytree RMVC72 block crusher has an output adjustment to make the material finer. Each crusher crushes to one size, though the size of the output varies somewhat.

Does the WIG 72 scoop, or do you feed it by hand?

The WIG 72 scoops its own material like a bucket, using a fixed, tapered cutting edge. Drive the crusher straight into the pile to load it; there is no hand-feeding.

Does the WIG 72 asphalt crusher need high flow?

No, the WIG 72 does not need high flow. The WIG 72 is set up to run at the high end of standard flow or the low end of high flow. High flow spins the drum a bit faster and could chew through material a bit faster over time, but the difference is not significant.

What happens if the WIG 72 jams?

If the WIG 72 jams, run the crusher in reverse to clear it.

The WIG 72 runs three hydraulic lines, and the third, smallest line is the case drain, a low-pressure line back to the skid steer's tank. If the crusher's motor jams or stalls, the relief pressure goes back to your skid steer's reservoir through the case drain, so it does not damage the seals on the hydraulic motor.

Is there a concrete crusher for skid steers?

Yes. The Raytree RMVC72 72-inch block crusher is a concrete crusher for skid steers that crushes concrete, brick and some asphalt. Broken concrete and brick from a washout pit can go through the Raytree RMVC72 and be reused as rock.

The Raytree RMVC72 and the WIG 72 are nearly identical crushers apart from the name and some slightly different bracing. The Raytree RMVC72 is listed at 10 to 17 gallons per minute (GPM), and customers have run both the RMVC72 and the WIG 72 on standard flow without complaints.
