Overview

4-ton dump-style pothole patcher with oil-jacketed heating. Keeps asphalt at working temperature for up to 48 hours and dumps material directly into the pothole.

Auto temperature controls

Holds working temp for 48 hours

Truck-mounted or tow-behind configurations

Who This Is For

Municipal road departments and county highway crews that patch potholes daily and need to dump hot mix directly into the hole without shoveling. If your current workflow involves shoveling asphalt out of a dump truck, wasting material, burning time, and wearing out your crew, the SPHD-4.0 eliminates that entire step.

Ideal Applications

Daily pothole repair on municipal road systems

Utility cut restoration and trench patching

Winter emergency pothole response

County highway maintenance on rural road networks

Large-volume patching programs with dedicated crews

What Sets It Apart

The oil-jacketed heating system keeps 4 tons of asphalt at working temperature for up to 48 hours with no burning and no cold spots, problems that direct-flame hot boxes create constantly. Dump-style discharge means your operator positions the truck and dumps material directly into the pothole. No shoveling, no wasted material, no back injuries. Auto temperature controls maintain the right temperature without operator babysitting.

Common Upgrade Path

Departments currently shoveling cold or degraded asphalt out of open dump trucks, crews using direct-flame hot boxes that burn the material on the bottom, or operations buying bagged cold patch as a temporary fix.

When to Consider a Different Model

If your patching volume is light, a few holes per week, the SPHD-3.0 delivers the same heating and dump capability at a lower cost. If you don't need dump capability and already have a way to place material, the SPH-4 Hot Box keeps material hot for less.
