ZOOMLION ZR420A rotarydiggingmachine: high-end technology remake of the classic
About ZOOMLION, I believe it has become a well-known heavy machinery enterprises, in recent years, ZOOMLION high-end technology remodeling classic series of products, the grand launch of the ZR420A rotary drilling rig.
ZR series, which is famous for its economy, high efficiency, reliability and intelligence, has gained the favor and purchase of many users. Among them, the ZR420A rotary drilling rig, which has won the TOP50 award of the 2013 annual product of China Construction machinery, is one of the representative works. The machine has the characteristics of wide range of operation, high construction efficiency, strong power, stable performance, high reliability and easy installation, thus becoming the ideal construction equipment of large pile foundation engineering.
Strong power, high energy saving
ZOOMLION ZR420A rotarydiggingmachine: high-end technology remake of the classic
ZR420A rotary drilling rig has super expansion performance, auxiliary winch adds free falling hook and other functions, can assemble hammer hammer, DTH hammer, etc., for multi-functional joint construction. The high efficiency mode and fast walking function of the power head are added, and the speed of quick pressurizing and pulling can reach 10m/min and 19.25m/min respectively.
In addition, a series of 4 outrigger hydraulic cylinders and a H support hydraulic cylinder are added to the series, so that the crawler rack and the upper and lower transport vehicles can be easily dismounted during the transition. In addition, the hydraulic oil particle detector is added to detect the cleanliness of oil, real-time alarm of oil pollution degree, to ensure the safety of oil circuit and oil quality, and to prolong the service life of hydraulic components. The automatic temperature control energy saving system is improved, which can automatically collect hydraulic oil temperature, and intelligently control the cooling fan speed according to the system settings.
In addition, ZR420A rotary drilling rig also uses the first construction of the combined construction technology with the whole casing, DTH hammer, hammer and other equipment combined construction, greatly improving the equipment development capacity, saving costs for customers. According to the drilling requirements of ultra deep and super large diameter, the mast wiring and the pressure hydraulic cylinder are reformed, so as to enhance the convenience of transportation and maintenance.
Reliable, stable, absolutely safe
According to the different application requirements of rotary drilling rig under various complicated conditions, the research and development personnel carried out the overall optimization design and improvement of the chassis, so as to make it have many characteristics such as economy, environmental protection, high efficiency and stability. The supporting parts in the chassis, such as engine, hydraulic components and electrical components, are all well-known brands in the world, and give full reliability guarantee to the performance of the host, and guarantee the stability and reliability of the product.
ZR420A rotary drilling rig adopts ZR series rotary drilling rig special chassis, which integrates ZOOMLION technology in the field of hydraulic tracked chassis for many years.
The power head automatic control system can adjust the pressure automatically with the change of drilling depth, especially in deep drilling, it can prevent the bending deformation of the drill pipe, broken rod and buried drilling and other major accidents.
It is worth mentioning that ZR420A adopted an improved double triangle variable amplitude structure, and raised the support point of the mast hydraulic cylinder to ensure the stability and reliability of the whole machine when entering the rock. The difficult drilling conditions, 3 rotary speed reducer configuration can effectively enhance the braking effect, prevent body deflection, with outrigger hydraulic cylinder can effectively inhibit the body front up, to further improve the stability of the whole machine, so as to ensure the drilling verticality, and can effectively avoid the fracture accident of drill pipe.
At the same time, the additional servo compression and pulse breaking rock can make the equipment easier and easier in the face of more severe conditions. The main hoist adopts a new encoder counting scheme, and the hole depth is more accurate. Adding independent oil feeding function can effectively prevent the occurrence of slide rod accident, so as to greatly improve the safety of equipment.
Wonderful recommendation:
