Scaffold 350 Type Spiral Drilling Machine

Q1: What is the biggest highlight of this Scaffold 350 Type Drilling Machine? What projects is it mainly suitable for?

A: The biggest highlight is the combination of large diameter and ultra-deep drilling. It offers a bore diameter of 40-600mm and a bore depth of up to 0-12 meters. It is perfect for: 1. PV Power Stations: deep foundation drilling for PV supports; 2. Agricultural Irrigation: small deep water wells and deep-hole orchard fertilization; 3. Infrastructure: power pole planting, highway guardrail post drilling, and building foundation exploration. It is a highly cost-effective, all-around model bridging the gap between large crawler rigs and handheld augers.

Q2: The parameter table lists engines as "Runtong/Lonxin/Zongshen/Yamaha". What is the advantage of this?

A: This is the core quality guarantee of the machine. We only use top-tier domestic and international brand engines (like Yamaha) with air-cooled four-stroke technology. This means: 1. Strong power to avoid jamming in hard or frozen soil; 2. Low fuel consumption and no need for oil mixing, making operation extremely convenient; 3. Parts for these top brands are globally available, keeping after-sales maintenance costs extremely low for overseas clients.

Q3: The total weight is approx. 100KG, with dimensions of 75*75*200/250/300cm. How is it transported in complex terrains (like mountains or orchards)?

A: Despite being a scaffold type, it is designed for high portability. It supports quick-release modularization. After removing the long drill rods and lifting scaffold, the main unit is manageable for 1-2 workers to load onto a pickup or agricultural vehicle. The customizable special sizes (200/250/300cm) mean you can choose a shorter bracket version to maneuver under low orchard canopies or inside greenhouses with extreme flexibility.

Q4: The rod connection is "spline pin fixation". Does it loosen easily when drilling in hard rock?

A: Absolutely not. Spline pin fixation is a very mature and reliable connection method in construction machinery. The spline can withstand immense torque, and together with the locking pin, it ensures that the drill rods do not slip or disconnect during high-speed rotation or when hitting hard formations. The power transmission efficiency is extremely high, making it much more durable than standard threaded connections.
