Why are SANY used rotary drilling rigs best-suited for cold-weather construction? – hnironrubikcubemachine.com

Winter brings harsh realities to construction sites—frozen terrain, equipment malfunction, and slow productivity. Yet certain machines thrive despite the freeze. So, why are SANY used rotary drilling rigs widely regarded as the top choice for cold-weather drilling? Let’s break down the answer from technical and field-tested perspectives.

The core advantage of SANY used rotary drilling rigs is their preheating engine system. Unlike standard rigs, which struggle with ignition in temperatures below -10°C, these units include self-regulating thermal wraps and low-temp-resistant starters.

On a bridge project in Harbin, China, where temperatures reached -22°C, a reconditioned SANY used rotary drilling rig started on the first attempt every morning for six consecutive weeks.

Frozen hydraulic fluid can cripple a rotary rig. However, Reconditioned rotary drilling rigs from hnironrubikcubemachine.com include system-wide insulation, and their hydraulic tanks are equipped with heating coils.

SANY used rotary drilling rigs show no loss in pressure even when idle overnight in minus-degree settings. Second-hand rotary drilling rigs, when upgraded properly, outperform some newer models due to the reliability of tested components under stress.

Drilling through frozen clay and permafrost is an extreme task. XCMG used rotary drilling rigs, although excellent in medium-firm ground, require additional bit reinforcements in icy terrain.

By contrast, SANY used rotary drilling rigs deliver higher torque and are better suited for hard, cold soil layers. Many contractors now opt for reconditioned versions tailored to these needs.

Winter work increases safety risks. Reconditioned Second-hand rotary drilling rigs include heated operator cabins, anti-slip walkways, and frost-proof hydraulic lines—ensuring operator comfort and uninterrupted drilling.

At a shipping port under development in northern Russia, two SANY used rotary drilling rigs and one XCMG used rotary drilling rig drilled over 60 holes for concrete piers. Even in -25°C, the SANY rigs ran 9+ hours daily, with just one minor downtime over 30 days.
