PRODUCT DESCRIPTION
The HH-300JDL water-air dual-purpose drilling rig is a mechanical top drive drilling equipment that integrates water drilling and air drilling. It solves the difficulty in drilling soil layers with air drilling and air DTH hammers, hard rock layers, gravels, and pebbles. Due to the low construction efficiency of water drilling mud drilling, the water-gas dual-purpose drilling rig is suitable for various formations, and it is efficient and energy-saving for drilling wells and geological exploration.
PRODUCT FEATURES
1. The drilling rig can choose a five-speed manual integrated gearbox, hydraulic release bearing, full synchronizer shift, high reliability and long service life;
2. The drilling rig adopts a mechanical hoist, which has a fast lifting speed and is convenient for handling bottom hole accidents.
