    Product Q&A

    What working conditions are horizontal directional drilling rigs primarily used for?

    It is primarily used for trenchless installation of underground pipelines and is suitable for the construction of crossings for telecommunications, gas, and water supply and drainage pipelines.

    Can a horizontal directional drilling rig penetrate both soil and rock formations?

    Standard models are suitable for soil layers; for rock formations, a rock‑drilling attachment kit must be selected.

    What is the maximum drilling depth achievable by a water well drilling rig?

    Drilling depths vary by model; standard models cover 100–350 meters, with options available to suit specific requirements.

    Is the water well drilling rig hydraulically driven, and does it support a diesel engine as its power source?

    The entire machine is hydraulically driven and can be equipped with either a diesel engine or an electric motor as its power source.

    Is a drilling rig suitable for constructing rural drinking-water wells and engineering dewatering wells?

    Fully applicable and widely used for domestic drinking wells, agricultural irrigation wells, and construction dewatering wells.

    Is the wheeled pile driver easy to move, and does it require trailer transport?

    The wheeled chassis is self-propelled and can move under its own power over short distances; for long-distance transport, towing is recommended.
