Rotary drilling rigs offer a wide variety of drill bits and powerful functionality.#rig sales#
1. Rotary drilling rigs can operate continuously, and can be equipped with a hydraulic grab bucket or twin-wheel milling machine for continuous construction.
2. The auxiliary winch has an automatic rope release function, and impact drill bits and impact-grab drill bits can be selected for drilling large-diameter pebbles or boulders.
3. Equipped with an air chamber and swivel, it can perform gas-hydraulic drilling. If equipped with a dual-power head or a casing tumbler, it can perform casing drilling, which is an effective method for solving quicksand, broken gravel, and silt layers.
4. When the thickness of the sediment is critical or when drilling underreaming is required, a special sediment removal bucket is needed. When drilling into the casing, the gap between the drill bit and the casing is small. To prevent the drill bit from snagging on the casing and to reduce suction, the selected drill bit should have a vent hole and a guide device. The opening and closing device should be located as close as possible to the center of the drill bit, and the operator should be integrated with the rig. This special problem can also be solved by selecting a combination of drill bits.#rig sales#
