Products Description
But on construction sites across Central Asia, it is the most hassle-free, rugged, and undemanding unit you can find.
High-pressure systems have their advantages, but medium-pressure systems offer stability. For a working machine, stability is far more important than sheer brute force.
Compared to high pressure, medium pressure

Many seasoned veterans in the construction industry understand a fundamental truth: high pressure isn't a cure-all; in fact, medium pressure often proves to be more durable.
Many sites have purchased high-pressure drilling rigs, only to face constant issues: hydraulic hoses bursting every few days, hydraulic fluid overheating and turning black, and repairs causing week-long delays.
Our Medium Pressure Crawler Drilling Rig adheres to one simple principle: 20 MPa medium pressure-it's sufficient, rugged, easy to repair, and not finicky.

Its biggest difference compared to high-pressure rigs is this: it doesn't compete on pressure; it competes on stability.
20 MPa Hydraulic Pressure: Neither too high nor too low-it's just right. Hoses won't bulge, fittings won't leak, and the hydraulic pump won't suffer from premature wear.
80–158 L/min Flow Rate: A medium-pressure, high-flow design ensures rapid operation; it won't feel sluggish just because the pressure is lower.
Dual Hydraulic Motors + Five-Star Motor: While the pressure isn't high, the torque certainly is-capable of handling everything from soft soil to crushed rock.
Dual Electronic Hydraulic Oil Coolers: Medium-pressure systems naturally generate less heat than high-pressure ones; with the addition of dual cooling units, you can work continuously even in the heat of summer.

The Practical Benefits of a Medium Pressure Drilling Rig in the Field
Unafraid of Poor-Quality Local Oil: High-pressure rigs using standard hydraulic oil will foam up and degrade within three days. Our medium-pressure machine runs perfectly fine on standard No. 46 hydraulic oil.
Easy to Repair-Any Mechanic Can Do It: High-pressure systems require specialized tools and diagnostic software to adjust parameters. Our medium-pressure system is just like an excavator-any local heavy-equipment mechanic could fix it with their eyes closed.

Affordable and Accessible Spare Parts: Hoses, fittings, and seals all use universal specifications, so you won't have to wait for parts to be shipped directly from the manufacturer.
Easy to Start in Winter: Medium-pressure systems can still operate even when the hydraulic fluid thickens in cold weather, whereas high-pressure rigs often stall out when starting from cold.
No Overheating Issues in Summer: The 20 MPa system generates very little heat to begin with, and with the dual electronic cooling system, it keeps running smoothly even in scorching temperatures of 40–50°C.

Applications
- Photovoltaic Piling
- Highway Guardrail Holes
- Wire Mesh Fence Post Holes
