Shaft Drilling Rig（Hydraulic）

The full GYSJZ series high-efficiency hydraulic shaft drilling rigs are advanced, high-efficiency mechanized rock-drilling special equipment developed for deep, large-diameter and hard rock shafts.

This series includes five models: GYSJZ3.6, GYSJZ4.8, GYSJZ4.10S, GYSJZ6.12 and GYSJZ6.12S. The equipped rock drills feature high drilling efficiency and powerful driving force, while the drill jib is lightweight, eliminating the need for extra large hoisting winches.

Meanwhile, hydraulic rock drilling has the following advantages compared with pneumatic rock drilling:
Energy Saving: For drilling rigs with a given drilling capacity, the power required by the electro-hydraulic system is only one-third of the power loss of pneumatic drilling. Low power loss results in remarkable energy savings.
High Drilling Efficiency & Fast Drilling Speed: Comparative tests show that under identical rock conditions and hole diameters, the drilling speed of hydraulic rock drills for deep holes is more than three times that of pneumatic rock drills, reaching 0.8–1.5 meters per minute.
Lower Drill Rod Cost: Hydraulic drilling parameters are adjustable to achieve optimal drilling performance for various rock formations. Additionally, hydraulic drilling generates gentle impact stress waves with high transmission efficiency, cutting the consumption of drilling tools and drill rods by 15–20%.
Reduced Overall Drilling Cost: Hydraulic pressure is approximately ten times higher than pneumatic pressure. At the same impact power, hydraulic rock drills adopt pistons with smaller bearing areas close to the shank area of drill bits, minimizing stress transmission loss and ensuring uniform stress distribution. This extends service life and reduces breakdown frequency, lowering comprehensive operating costs by around 30%.
