Mastic Melters & Applicators

Patcher 4

Get more done with the Patcher 4 Mastic Melter: Increased capacity and performance to handle any workload you put in front of it.

Crafco Patchers have been a leader in the industry for more than 20 years. Our latest innovation, the Patcher 4, is engineered to meet today’s toughest demands. With a 395-gallon tank and an enormous daily melting capacity of 24,000 pounds, waiting for material to melt is a thing of the past. The Patcher 4 offers maximum productivity, simple operation and reliability without compromise.

Our 411,000 BTU burner and double-boiler system melt material fast, while intuitive digital controls keep the temperature just right to meet ASTM specifications. Crafco’s engineers maximized the tank size while keeping the loading height low for safety. And the Patcher 4 sits on a heavy-duty trailer built to last.

Other Patcher 4 features:

  • High-torque gearbox handles thick material and aggregate without stalling.
  • Angled and staggered agitation blades prevent dead spots, keep temperature even and prevent settling.
  • Two anti-splash loading doors for faster material loading, with automatic safety shutoffs to protect your crew from hot material splashes.
  • Bucket storage and heated toolbox for more efficient workflow.

Get even more out of your Patcher 4 with our optional power auger chute, which routes material outside the wheel path for safer and more efficient distribution. We thought of everything so you can focus on the job.
