Mechanical Top DriveJDL350 Mechanical Top Drive Rig
JDL350 mechanical top drive rig uses automotive 525 transmission with transmission efficiency doubled compared to hydraulic drive, reducing energy consumption by 35%. 10500N·m ultra-high torque solves challenges in soil layer DTH hammer drilling and hard rock formation construction.
Product Overview
The JDL350 water well rig is a complete equipment solution designed by ShuZhiHui for large-diameter water well construction, with maximum drilling depth of 500m and maximum opening diameter of 350mm. This model uses a Cummins 118kW engine as the power source, equipped with an 8000-10000N·m high-torque hydraulic system, suitable for deep water wells and complex formation construction.
The JDL350 is equipped with a hydraulic crawler chassis for flexible movement, suitable for complex terrain. Drill pipe specifications cover 76/89/102/114mm, flexibly selectable based on well diameter requirements. 30T pull-out load ensures smooth casing running and pulling in complex formations.
