Material Temperature Support
The HB4T keeps plant material hot and can warm cold mix to a better working temperature for repair crews.

The LeeBoy HB4T Hot Box keeps plant mix hot, warms cold mix, and gives contractors or municipalities a compact 4 ton material support trailer.
Where it fits
The HB4T is not a full patching machine like a Thermo-Lay or RA-400. It is a hot box trailer that keeps asphalt material hot and workable for potholes, utility cuts, and small repair work.
LeeBoy literature lists a 4 ton hopper, thermostatically controlled heat, one 105,000 BTU diesel burner, dump hopper, and trailer-mounted configuration.
This is a smart fit when the crew already has hand tools, compactors, and labor in place but needs reliable hot material support instead of letting mix cool in an open truck bed.

Feature details

The HB4T keeps plant material hot and can warm cold mix to a better working temperature for repair crews.

The large single-scissor dump hoist helps unload material cleanly while keeping the hot box compact and towable.

Storage, wet box, pump spray holder, compactor basket, hoist, washdown, and plate compactor options let crews tailor the trailer.
