Products Description
A PV Support Pile Machine built specifically for solar farms. Not a modified excavator that "kind of works" for piling – this one starts with an 8‑ton excavator chassis, then adds the hydraulic flow, rotation torque, and boom articulation you actually need for driving PV support piles.
We've seen crews struggle with undersized rigs that overheat by noon. The TZ‑300A doesn't do that.
Why the TZ‑300A Works
The undercarriage
A full 8‑ton excavator track frame. Track length 3000 mm, width 2200 mm. That's not a toy. It gives you low ground pressure on soft or reclaimed land – you won't sink into wet soil after a rain.
Swing without moving the tracks
360° continuous swing. The internal tooth ring is 1 meter in diameter. Why does that matter? Because in a dense pile field, you can drill one hole, swing to the next, and keep going. Less track movement means more holes per day.
Where It Gets Used
- Solar ground mounts – the obvious one. Holes for steel piles, H‑beams, or concrete anchors.
- Fencing on farms – post holes in rocky ground where a skid steer auger won't cut it.
- Small foundation drilling – for lighting poles, sign structures, or communication towers.
- Soil investigation – light geotechnical drilling if you swap to a coring bit.
But honestly, 90% of these machines go to solar projects. That's what it's designed for.

FAQ
Q: Can it drill deeper than 3 meters?
A: Yes. Standard is 3 m, but the factory will customize. Ask about longer leader or additional rod options.
Q: What's the difference between the two hydraulic motor options?
A: Dual motor setup is balanced and reliable. The five‑star motor gives higher starting torque – useful if you're drilling through clay with rocks. For most solar sites, dual motors are fine.
Q: Does it overheat in summer?
A: The dual electronic oil cooler helps a lot. That said, no machine is magic – check your hydraulic oil level and keep the cooler fins clean. Do that, and you can run full shifts in 40°C weather.
Q: How many holes per day?
A: Depends on soil, depth, and operator. In sandy loam at 2 m depth, experienced crews get 150–200 holes per day. In hard clay with rocks, more like 70–100. The 360° swing and fast feed help.
Q: Is it hard to transport?
A: About 5 tons. Fits on a standard flatbed trailer. No oversize permits in most places. Width is 2.2 meters – well under the 2.5 m legal limit in many countries.
