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. Chupp Industrial sells it, and this post covers how fine the asphalt crusher crushes, how it loads, what hydraulic flow it wants and what to do if it jams.

How fine does the WIG 72 asphalt crusher crush?

The WIG 72 skid steer asphalt crusher crushes material to about two inches or smaller, with no adjustment to make it finer. What comes out is a rough base material, not a finished small gravel you could grade smooth on a driveway.

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

The WIG 72 asphalt crusher scoops its own material like a bucket, using a fixed, tapered cutting edge. Drive it 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 asphalt crusher does not need high flow; it runs at the high end of standard flow or the low end of high flow. High flow spins the drum a bit faster, but it makes little real difference in how much material it gets through.

Chupp Industrial also sells a Raytree version, the RMVC72. The two are nearly identical apart from the name and some slightly different bracing, and the RMVC72 is rated for 10 to 17 gallons per minute (GPM). Customers have run both on standard flow without complaints.

What happens if the WIG 72 jams?

If the WIG 72 asphalt crusher jams, run it in reverse to clear it; its case drain protects the hydraulic motor seals while it is jammed.

The crusher runs three hydraulic lines, and the third is the case drain, a low-pressure line back to the machine's tank. If the 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 skid steer crusher for concrete and brick?

Yes, the Raytree 72-inch block crusher that Chupp Industrial sells will crush concrete, brick and some asphalt, so broken material from a washout pit can go back to work as rock.
