A track-retractable pile foundation pore-forming equipment with high performance which is researched and developed independently
ZTR series rotary drilling rig is a track-retractable pile foundation pore-forming equipment with high performance that is researched and developed independently by our companyI through introducing advanced technology and based on the mature parts home and abroad. The rotary drill rig , of which the key performance specifications has reached and even exceeded the same products of the world, absorbs advantages of worldwide well-known brands on design and technique, and uses international famous parts, which make sure the complete machine’s reliability. As an efficient pore-forming equipment of wide bore pile foundation engineering construction, it is applied in all kinds of city traffic construction, bridges of railway and road, and high-rise buildings. Its matching casing oscillator can produce powerful driving torque and overdraft to case in hardcore, thus it especially adapts to those constructions in coast, mudflat, waste cities, deserts and building groups.
Main features of ZTR series rotary drill rig :
1.Hydraulic retractable tracked chassis, auto lift, fold mast, and good stability.
2.Auto detection of verticality and hole depth, and the touch screen shows work state parameter directly.
3.Gross power controls the main hydraulic-circuit and the operation adopts pilot control, load sensing, which is convenient and sensitive for operation.
4.Caterpillar inter cooler, electrojet, turbo-supercharged engine, powerful horse-power.
5.It can complete a set of short spiral bit, common drilling bucket, drilling bucket etc, which can drill in clay bed, gravel, pebble bed and inter mantle rock.
6.Luffing mechanism adopts popular parallelogram structure, with flexible movement and high efficiency.
7.Electronic control system adopts CAN-BUS mass control technique, controls all the processes of engine, hydraulic pump and valve, and monitors the whole process of moving parts.
