HT-CM300: Fast, Frequent Batches on Tight Job Sites
The HONGTAI HT-CM300 self-loading tracked concrete mixer is sized for crews that pour little and often: fence posts, footings, steps and repair work where a 300 L batch is placed and finished before the next one is mixed. The front loader-style bucket fills the drum through a wide 750 mm mouth, the drum mixes on the move, and a 100° hydraulic dumping angle empties it cleanly at the pour point.
A Rato R420 15 HP gasoline engine drives the hydraulics and the 700 mm (27.6 in) wide rubber-track chassis, so the HT-CM300 keeps working on soft ground, slopes and narrow access routes where wheelbarrows and towed mixers slow the job down.

Why a 300 L Drum?
- Manageable batches: each load can be placed and finished before the concrete starts to set.
- Less waste on small pours such as post holes, pads and repairs.
- Same 15 HP power unit and chassis as the HT-CM500, so parts and servicing are shared across your fleet.
Typical Applications
- Foundations, footings and slabs in backyards and extensions
- Fence post, pole and sign base concreting
- Paths, patios, steps and small retaining walls
- Renovation work where a full-size mixer truck cannot reach
- Farm, stable and rural building projects
- Rental fleets serving builders and homeowners
