ZR185R Rotary Drilling Rig

ZR185R Rotary Drilling Rig

Rotary drilling rigs are foundation drilling equipment used to create boreholes for pile foundations on building, bridge, and urban rail construction projects. During drilling, a rotating drilling tool cuts through the ground and removes material until the hole reaches the required pile diameter and pile depth. The borehole can then receive a reinforcement cage before concrete pouring forms the bored pile that supports the structure.

The drilling tool needs to match the ground condition at the jobsite, since soil, sand, and rock each require a different approach to drilling. The required pile diameter and pile depth also affect how the borehole is made. In case the ground cannot hold the sides of the hole open, casing provides support while drilling and pile construction continue.

Advantages
  • ZOOMLION ZR185R rotary drilling rigs use the fourth-generation ROADS control system and high-flow hydraulic pumps and valves to deliver strong torque during drilling. When it is time to clear the drilling tool, the rotary drive can spin faster to throw off the excavated soil.
  • Their winch crowd system has a maximum stroke of 13,000 mm, so longer casing sections can be lowered in a single operation.
  • The Kelly bar can stay on the rig during transport, and the mast raises or lowers at the touch of a button. Operators therefore have fewer parts to remove and reinstall when moving to another site.
  • The rotary head comes with a casing driver for fully cased drilling. Operators can also switch on the hydraulic oil supply to a casing oscillator with one button when the job requires it; the rigs support fully cased drilling to depths of up to 20 m.
  • Operators can check the rig’s condition through dynamic monitoring and use the 720° camera system to see more of the surrounding area.
  • Their cold-start function helps the rigs start in low temperatures.
