SQR15 Rotary Drilling Rig

Multi-purpose rotary drilling rig is a hi-tech product integrated with machine, electricity and mechanics fluids with modern idea and methods to design and manufacture, which is one kind of intelligence, highly effective pile foundation hole-forming equipment. There are the following characteristics: 

 ◆Adopt rotary drilling rig hydraulic telescopic crawler dedicated chassis, ensure the whole machine stability, good mobility, and strong adaptability during operation.
◆Adopt the most advanced imported engine as power source, turbo supercharging upgrades the engine performance and power, direct fuel injection type electronics controller provides timely and accurate fuel charge, sufficient burning, to achieve strong power output with low fuel consumption, low emissions and low noise.
◆The lift system of main winch with the system optimization design increases the durable and safety coefficient, doubles the service life of steel wire, reduces the equipment's running cost in large scale. 
◆Adopt the double motors and double reducers with world famous Italian Brevini system, the rotary table can automatically adjust the drilling speed with the stepless speed regulation to meet high torque output and the demands for the hard ground layer at geological condition. Multi-point lubrication, three levels sealing of gearbox ensures construction requirements in severe environment. Heavy duty shock absorber reduces the impact of rotary table effectively.
◆The parallelogram system adopts the popular parallelogram structure, all pin rolls connection is with double support structure, each hinge point by optimal design could move swiftly, good stability and high efficiency operation.
◆The hydraulic system has the contemporary international advanced level negative flow control and the regeneration function, to meet the specific request and the energy saving purpose. The constant power and the electrical power override control, to bring engine into maximum function. The operation adopts the LS forerunner controlling for accuracy, sensitivity and safety. 
◆Electrical control system is the headquarter of the rotary drilling rig, using CAN-BUS technology, achieve the intelligent controls of engine monitoring, drill movements control, virtual instrument, fault detection and diagnosis, alarm and information display, etc.
◆Applied to locked and friction type drill bar, attachment could be short twist drills, universal drilling bucket, sand bucket, used for the clay bed, gravel bed, pebble bed and rock formation with a certain weathering degree.
◆The cabin with air condition and dust prevention may be used for windy and dusty with automatic defrosting, shockproof and sound-proof, tridimensional blowing-in, wide open, safety and comfortable, also available at construction the alpine and low voltage area.
