Overview
This crawler water well drilling rig weighs 4.7 tons, equipped with a 58kW Yuchai diesel engine, supporting a maximum drilling depth of 200m and hole diameter of 140-254mm. It adopts pneumatic impact rotary drilling technology with rotary torque 3400-4700N·m and penetration efficiency of 10-35m/h. The crawler chassis enables 30° gradeability, matched with high support legs of 1.4m stroke to adapt complex job sites. Featuring powerful lifting force and fast lifting & feeding speed, it is widely used for farm irrigation wells, domestic water wells, construction dewatering wells and shallow geological exploration. Only 2.6m loading width for easy transportation, simple operation and high cost performance for medium & small well drilling projects.
Description
Integrated Easy-Operation Control Panel
Integrated cabinet-type control console with centralized pressure gauges and control levers for clear operation view. All drilling actions are controlled in one area, easy to learn and greatly reduce operators’ work intensity.
Powerful Yuchai 58kW Turbocharged Engine
Equipped with Yuchai 4-cylinder turbo diesel engine of 58kW rated power, sufficient power reserve and steady continuous torque output. High power output with low fuel consumption, reliable for long-time outdoor drilling and lower operation cost.
35-35-20 Triple High-Pressure Hydraulic Pump
Standard 35-35-20 triple hydraulic pump with high oil pressure & large delivery flow, sensitive hydraulic response. Low energy loss, realize coordinated drilling, lifting and traveling movement with stable power supply under harsh rock conditions.
Efficient Dual Air Filter System
Dual air filter structure blocks construction dust and mud fully to protect engine. Adapt to dusty & muddy harsh outdoor sites, extend engine service life, reduce filter replacement times and maintenance cost.
Winch & Heavy-Duty Rotary Gearbox Assembly
Compact hydraulic winch with smooth low-vibration operation and flexible layout. Max lifting capacity 1.5 tons, safely assist drill pipe hoisting and lowering.
