The GYSJZ series hydraulic shaft drilling rig is an advanced, high-efficiency mechanized rock drilling equipment specially developed by our company for deep-water hard rock shafts. This series includes five models: GYSJZ3.6, GYSJZ4.8, GYSJZ6.12, GYSJZ6.12S, and GYSJZ6.14. All are equipped with the RC1200 high-power rock drill, featuring a lightweight drilling frame and eliminating the need for a large hoisting winch.
GYSJZ3.6 (132kW motor)
Drilling efficiency is 1-1.4 times that of the YSJZ3.6 drilling rig. It can meet the rock drilling and hole boring requirements for shafts with an excavation diameter of 4-6 meters.
GYSJZ4.8 (90kW×2)
Drilling efficiency is 1.5-2 times that of the YSJZ4.8 drilling rig. It can meet the rock drilling and hole boring requirements for shafts with an excavation diameter of 6-9 meters.
GYSJZ6.12 (132kW×2)
Drilling efficiency is 1-1.4 times that of the YSJZ6.12 drilling rig. It can meet the rock drilling and hole boring requirements for shafts with an excavation diameter of 6-12 meters.
GYSJZ6.12S (twin-boom drill)
Using two GYSJZ6.12 hydraulic shaft drilling rigs in an underground dual-rig drilling configuration. Powered by four 132kW motors and equipped with 12 RC1200 heavy-duty rock drills. It can meet the rock drilling and hole boring requirements for shafts with an excavation diameter of 12-16 meters.
GYSJZ6.14 (132kW×2)
The GYSJZ6.14 high-efficiency hydraulic shaft drilling rig is an advanced, high-efficiency mechanized rock drilling equipment developed for super-large hard rock shafts, capable of meeting the rock drilling and hole boring requirements for shafts of 12-14 meters.
