Crawler open pit down the hole drilling rig
Suitable for high-efficiency drilling operations in medium-to-deep blasting holes for open-pit projects in mining, quarrying, railways, transportation, water conservancy, building materials, and military applications. Also widely used for drilling in anchor rod support, channel excavation, and sewer engineering projects.
1. This drill rig features a dual-power design as standard, equipped with a 76mm diameter, 3-meter drill rod or optional multiple twist drill rods. It supports both diesel and electric power sources, allowing for instantaneous power switching. and electric dual-power models. Power sources can be switched at any time.
2. Features a high-torque dual-cycloid motor rotary power head, enhancing rotational torque up to 7200 N·m. This enables a wider range of rock drilling diameters and is widely applicable for foundation pit anchor rods, casing, and large-diameter twist drill rod operations.
3. Dual-speed rotation power switch valve for convenient operation, accommodating varying torque and speed requirements. 4. Standard configuration includes a plunger motor and national standard engineering machinery crawler tracks. Features strong climbing capability and reliable quality.
