HT12 Mini Excavator

The HT12 is a compact crawler mini excavator built around one idea: doing accurate work in places where a conventional machine simply cannot fit. Its total width measures only 930 mm, and the tail turning radius is just 945 mm, so the machine can drive through a standard doorway, turn inside a corridor and dig in a backyard corner without needing room to swing the counterweight.

Power comes from a Kubota Z482 / D722 diesel engine, paired with a Tengfei main control valve. With a working mass of 1200 kg, the HT12 keeps the weight low enough for easy trailer transport while still delivering a maximum digging depth of 1680 mm and a maximum digging distance of 2905 mm.

Full hydraulic pilot operation

The HT12 uses a full hydraulic pilot control system with joystick levers instead of mechanical linkage rods. The practical difference for the operator is shorter lever travel, faster response and far less physical effort per cycle. Fine grading, edge trimming and trench bottom cleaning become smooth, repeatable movements rather than corrections applied after the fact. Fatigue over a long shift is noticeably lower, which matters for owner-operators and rental fleets running one machine all day.

±60° side swing boom

The boom swings ±60° left and right. Instead of repositioning the entire machine to reach a corner, the operator swings the arm and continues digging along a wall foundation, fence line or trench edge. On narrow urban lots this removes most of the repositioning work that otherwise eats the day.

Dimensions that actually get it inside

At 930 mm wide, 2335 mm high with the canopy and 2440 mm transport length, the HT12 fits through garden gates and interior doorways, and it can be moved on a light trailer without a heavy haul permit in most markets. A front dozer blade with 190 mm digging depth handles backfilling and site levelling after the digging is done.

Customization

Body colour can be specified to match a brand or fleet identity. Attachment options cover narrow bucket, plain bucket, tilting bucket, sand bucket, auger, breaker hammer, rake, thumb clip, grabber and pallet fork, all mounted on the same quick coupling.
