The core advantages of the ZR180A rotary drilling rig of Zhonglian Heavy Machinery lie in three aspects: construction stability, operational efficiency, and fuel economy. It can meet the needs of most small and medium-sized infrastructure projects.
1. High stability, more reliable construction
The use of a parallelogram large triangular slewing mechanism ensures more uniform force distribution during drilling, reducing the risk of hole position deviation or collapse due to the shaking of the machine body.
The rear-mounted main hoist design optimizes the weight distribution of the entire machine, further enhancing the stability of the machine during operation, especially suitable for construction in complex geological conditions (such as soft soil, sand layers).
2. Outstanding operational efficiency, wide application scenarios
With a torque of 180kN/m and a maximum drilling diameter of 1600mm, and a maximum drilling depth of 62m (friction type), it can cover the drilling needs of most small and medium-sized infrastructure projects such as building foundations, municipal roads, and small bridges.
The main hoist lifting force is 170kN and the lifting speed is 71m/min. The speed of the drill pipe lifting and the removal of slurry is fast, which can effectively shorten the construction time for a single hole and improve the overall operational efficiency.
3. Good fuel economy, low operating cost
Equipped with a Cum-mins QSB6.7 engine and a load power matching design, it can automatically adjust the output power according to the drilling load to avoid fuel waste in idle or light-load conditions.
Compared with models of the same level that have not undergone power matching, long-term use can significantly reduce fuel consumption and lower energy costs during construction.
