Truck Chassis Dual-Purpose Borehole Drilling Machine with High Mobility

A water & air dual-purpose water well drilling rig is a versatile drilling machine that can operate using either water-based mud circulation or compressed air (or foam) as the drilling medium. This dual capability allows the rig to efficiently drill through different geological formations, from soft soil and clay to hard rock, using the most suitable method for each layer.

The key advantages include: One machine can handle both soft and hard formations without changing equipment Mud rotary drilling is ideal for unconsolidated formations (sand, clay, gravel) Air/DTH hammer drilling is much faster in hard rock Reduced need for multiple rigs on the same project Lower overall investment and operating cost Greater flexibility for varying geological conditions

The rig supports multiple drilling methods: Mud rotary drilling (using water or bentonite mud as circulation fluid) Down-the-hole (DTH) air hammer drilling (using compressed air) Foam drilling (air with foam additive for better cuttings removal) Combination drilling (mud for upper soft layers, air for lower rock layers) The operator can switch between methods depending on the formation.

We provide a standard 12-month warranty from the date of shipment. During the warranty period, we supply free replacement parts for manufacturing defects. Wearing parts such as drill pipes, hammers, bits, seals, and filters are not covered under normal wear and tear but can be supplied at competitive prices.
