The world's largest tonnage back-type rotary drilling rig
XR468F
The first show construction strikes, soft and hard strata are common
Directly tilt the drill mast backwards during transfer
The energy-saving efficiency value is full!
Recently, the world's largest tonnage back-mounted rotary drilling rig XCMG XR468F debut construction officially started. At the construction site of Zengtian Expressway in Baiyun District, Guangzhou City, XCMG XR468F was heroic and roaring, setting rods, drilling holes, lifting rods, and throwing soil In one go, the efficiency of the first show is amazing.
Granite rocks are widely distributed in the construction area, locally metamorphic strata and Quaternary loose strata, the geological structure is complex, and the construction pile diameter is 1.8m, the pile depth is 30-36m, the hole is 10m into the rock, and the rock hardness is greater than 100Mpa, which is also normal Such difficult construction conditions led the project party to choose the newly purchased first back-mounted rotary drilling rig XR468F for training.
In its first appearance, XR468F lived up to expectations and achieved outstanding results. With an average construction efficiency of 24 hours to complete a pile, it won full marks from the construction site engineering technicians, operators and project supervisors, opening up the market with its strength.
XCMG XR468F rotary drilling rig is equipped with imported 15L Cummins latest platform high-pressure common rail engine, equipped with a hydraulic system with large displacement main pump and large flow main valve, which ensures the powerful output of the hydraulic system and can directly reach the working device of drill pipe and drilling tools without reservation. The working efficiency is beyond the table; the power head has a large torque of 490kN.m, and the practical functions such as rock entry mode, stepless speed adjustment, constant speed cruise, drill pipe visualization, etc. have been carefully created, so that the "old, big, and difficult" rock entry stuck can be completely solved. High-efficiency construction is immediate!
In addition, the main winch is equipped with a super-long-life reducer and a super-large lifting force of 48 tons. It adopts XCMG’s industry-leading single-row rope technology to effectively solve the problem of wire rope wear and increase the service life of the wire rope by 2-4 times; the special telescopic crawler chassis, Large-diameter heavy-duty slewing bearings, double-arm large parallelogram luffing mechanism, and the drill mast can be tilted back directly when transferring to another site, so that the speed is one step ahead, and construction in mountainous areas is no longer afraid of transfers!
The XR468F is equipped with a 12-inch touch screen display, one-button return to normal, one-button dumping, bottom protection, automatic pressure limit, maintenance reminders, and fault diagnosis at a glance, truly reaching the car-level comfortable and intelligent control experience.
It is reported that the Guangzhou Zengcheng-Foshan Expressway (Zengcheng-Tianhe section) project (referred to as Zengtian Expressway) has a total length of 38.4km. After completion, it will realize an important measure of Guangzhou's spatial development strategy of "extending the south to the north, connecting the east to the west"
