In historic Ecuadorian cities, open-cut utility work is close to impossible. Permits for road excavation take months. Traffic diversion on narrow colonial streets draws public complaints. And restoring stone or paved surfaces costs more than the pipe installation itself. A municipal contractor in Cuenca faced exactly this situation on a new water main. The line had to cross a busy street and a protected heritage pavement. The contractor needed a compact, reliable Horizontal Directional Drilling Rig that could mobilize through tight access and hold a clean bore in volcanic soil.
Why This Ecuador Project Needed a Horizontal Directional Drilling Rig
The contractor had used a smaller horizontal directional drilling machine on previous fiber jobs. It worked in soft ground but struggled when the geology changed. This project was different in five specific ways:
- Heritage pavement protection. The crossing passed under a protected stone surface. Any surface settlement or mud fracture would have stopped the job.
- Volcanic ash with scattered cobbles. The soil report showed loose volcanic ash over scattered cobbles. The cobble content was scattered, not a continuous cobble layer. This ground can collapse if mud volume and pressure are not stable.
- Narrow launch site. The entry pit sat in a side street barely wide enough for a small truck. A large rig could not enter without a crane and a road closure.
- Fixed utility tie-in date. The water utility had scheduled valve and meter work around the bore. Late completion meant idle municipal crews.
- Local parts and service gap. The contractor wanted a machine with simple maintenance and accessible spare parts, not a complex import with long lead times.
The contractor did not need maximum pullback force. It needed a Horizontal Directional Drilling Rig sized for medium utility bores, with enough mud flow for unstable ground and a footprint that fits an urban street.

The HDD Drill Rig Selected for the Mountain Crossing
YG recommended the YG-180 HDD drill rig. It is the mid-entry model in the YG line: 97 kW engine power, motor-driven push and pull,Φ600 mm maximum reaming diameter, and 250 L/min mud flow. For a 120-meter crossing with a 200 mm HDPE water pipe, these specs leave working margin without excess weight. At 8,500 kg and 6.4 m long, it moves on a standard flatbed and fits through the side-street access.
| Parameter | YG-180 |
| Engine rated power | 97 kW |
| Push and pull system | Motor |
| Max reaming hole diameter | Φ600 mm |
| Drill rod length (single) | 3 m |
| Drill pipe diameter | Φ60 mm |
| Drill angle | 10–22° |
| Max mud flow | 250 L/min |
| Max mud pressure | 80 bar |
| Overall weight | 8,500 kg |
| Dimensions (L×W×H) | 6.4 × 2.27 × 2.34 m |
Results Delivered by the HDD Drilling Machine
The contractor completed the pilot bore, one reaming pass, and pullback inside the planned window. Measured against the open-cut estimate the municipality had prepared, the HDD drilling machine produced these results:
- 30% faster completion from mobilization to pullback, because no excavation, shoring, or pavement restoration was needed.
- Zero surface disruption on the heritage street. The pavement remained intact and open to pedestrians throughout.
- One reaming pass to final diameter, supported by stable 250 L/min mud flow in the volcanic ash section.
- No major tooling replacement in the volcanic ash section; the scattered cobble interval was crossed with adjusted mud parameters.
- Lower fuel use per meter than the contractor’s previous smaller unit, due to fewer stoppages and a single-pass bore.
For a contractor comparing an HDD machine for sale, the advantage was predictability. The YG-180 matched the bore profile without oversizing, so mobilization and site setup stayed simple.


FAQ about Horizontal Directional Drilling Rig
Q: How much does a YG-180 HDD Machine cost in Ecuador?
Pricing depends on drill rod package, mud pump configuration, and shipping terms to Ecuador. YG quotes directly because freight and customs change the total. Send your bore diameter and crossing length for a current quote.
Q: What spare parts support is available after purchase?
YG provides a recommended spare parts list with each order, covering common wear items and hydraulic components. Parts can be shipped directly to Ecuador, and the company offers remote guidance for replacement and maintenance.
Q: What is the typical delivery lead time to Ecuador?
Lead time depends on the configuration and the shipping route. Standard YG-180 configurations are usually prepared for shipment within a few weeks, and ocean freight to Ecuador adds transit time. YG confirms the schedule with the quote.
Q: Is training available for local crews?
YG provides operation and maintenance guidance, spare parts access, and remote technical support. Commissioning support can be arranged for first-time HDD operators in Ecuador.
