HT-260

HT-260 drill rig is a new type of shallow hole core drilling rig with mechanical transmission system and hydraulic pressure feeding system. It is mainly manufactured for engineering geological exploration, small-scale water well drilling and engineering construction for highway, railroad, hydropower, harbor, etc. It is also applicable to shallow hole alloy core drilling and diamond core drilling

Features

1. Diesel engine or electromotor is available to satisfy various engine demands.
2. Higher reliability and intensity as well as stronger capacity compared with similar drill rigs in China.
3. Connecting rod reinforcement spring clamp and hydraulic chuck enjoy novel structure, large clamping force, long service life and reliable performance.
4. Six rotational speeds meet demands of a wide range of applications.
5. Six reverse rotational speeds can realize automatic rod unloading, helping to tackle drilling accidents with lower labor intensity and higher safety.
6. Components of this core drilling rig are almost identical and interchangeable, facilitating replacement and maintenance.
7. Easy to fix the core drill, and stable under high-speed drilling.
8. Light weight and easy to assembly and disassembly. This drill rig can be disassembled into 4 integral parts, allowing convenient transportation and drilling working in mountainous areas and underground tunnels.
