Product Feature
Rotary Drilling Rig ZR280C
• Can be equipped with casing drives, preserving the installation
interface for hydraulic oscillators, especially suitable for geological
conditions, such as sand & gravel, fill material, and karst, soil
with rich groundwater, etc ;
• The drilling depth can achieve 58
meter with inter-locking Kelly bars if equipped with optional mast
extensions and standard counterweight chips;
• Line pull of the main
winch gets to 290 kN. It helps to take more soil out in one go and
increases drilling efficiency. Can be equipped with Zollern gearboxes
and drums, which helps to achieve higher safety and higher reliability,
meeting more demanding drilling requirements;
• It makes mast
erection and lowering-down more safe and convenient with cylinders to
fold the mast or cathead and automatic handle operation in the cab. Can
be equipped with standard counterweight chips to increase drilling
safety.
