• 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.
