Shaft Drilling Jumbo, Hydraulic Shaft Jumbo, GYSJZ (Vertical Shaft Drills)
The GYSJZ shaft drilling jumbo is a specialized, high-performance drilling machine developed to meet the demands of deep, hard-rock vertical shaft excavation. The drilling machinery is powered by a robust 132kW motor and equipped with three heavy-duty hydraulic drifters, enabling it to handle drilling diameters from 4 to 6 meters. Its lightweight frame (weighing less than 7 tons) eliminates the need for oversized hoisting equipment, offering a cost-effective solution for your drilling needs.
- High power, high speed The drilling machine is equipped with the RC1200 hydraulic drifter, achieves drilling speeds 1.2 to 1.5 times faster than other models on the market. This allows for rapid and efficient drilling in challenging rock conditions, ensuring timely project completion.
- Customizable for enhanced efficiency The adaptable hole diameters (⌀45, ⌀51, ⌀54) allow operators to optimize drill hole size and spacing based on project needs. The use of larger hole sizes and strategic spacing can reduce the number of drilling holes required, boosting both productivity and blasting effectiveness.
- Safety-integrated design The shaft drilling jumbo is equipped with emergency stop buttons on both the control panel and work surface, allowing for immediate shutdown in the event of equipment malfunctions. This protects vital components like pumps and minimizes oil leakage, helping to avoid unnecessary downtime and maintenance costs, while ensuring the continued optimal performance of the pumps.
