Sany rotary drilling rig

SR285

High-efficiency construction of rock and soil: the medium-sized rotary drilling rig with the largest sales volume, the newly upgraded sixth-generation drill pipe, the integral pressure table, upgraded materials, reinforcing ring, etc., and the construction capacity of hard soil layer and rock layer increased by 10%. Economical and energy-saving: using power optimization control technology, real-time power distribution, compound action response is smooth and fast; and high fuel utilization, low comprehensive fuel consumption, saving 6 to 100000 yuan per year.

Sany rotary drilling rig

SR155

Advantages: 1. As a rotary drilling rig, the SR155-C10 has a strong drilling capacity and efficient drilling speed, which can meet the construction needs under various geological conditions. 2. It adopts the technology independently developed by Sany Heavy Industry, which has stable and reliable performance and excellent operability, and has low requirements for operators. 3. The fuselage structure is sturdy, durable, suitable for various harsh construction environments, and has a long service life. 4. The equipment is equipped with advanced control system and automation function, which can realize high-precision positioning and operation and improve construction efficiency. 5. Equipped with a large-capacity fuel tank and fuel saving technology, it can work continuously for a long time, reducing maintenance and downtime. Disadvantages: 1. The SR155-C10 is large in size and heavy in weight, which requires larger site space and larger transportation equipment to carry out transportation, and is not suitable for construction sites with limited construction space. 2. Because it is a rotary drilling rig, the SR155-C10 is only suitable for drilling operations and cannot perform other types of work, such as excavation and lifting. 3. The price is higher, for small construction companies or individual builders, may not be able to afford such investment costs. 4. Although the positioning accuracy is high, there may be some adaptability problems for some special geological conditions or complex terrain operations. 5. The requirements for operators are high, and they need to have certain technology and operation experience, otherwise it may lead to the decline of construction quality or the occurrence of safety accidents.

XCMG rotary drilling rig

XR240E

XXCMG XR240E rotary drilling rig performance characteristics: 1.As a multi-functional machine, XR240E can realize the quick switching of functions such as crowd cylinder, crowd winch to meet more different construction needs; 2.It adopts Isuzu electronically controlled turbocharged engine with lower fuel consumption and convenient service; 3. The rotary drive and main winch performance is increased by 20%, so the work efficiency is much higher; 4. The main and auxiliary winches both adopt the single-row rope technology, the service life of wire rope is 2 ~ 4 times longer than that of multi-layer rope, which makes the cost lower; 5. The double jib parallelogram luffing mechanism has a large support angle and a 16% increase in support range,which makes the operations more stable; 6. The hydraulic system adopts negative flow control technology which has a fast response and good handling performance; 7. High-power temperature-controlled independent hydraulic oil cooler can meet the construction requirements of high- temperature areas and adjust the fan speed accorading to temperature changes to achieve energy saving; 8. The intelligent control system can achieve functions such as automatic adjustment and display of mast perpendicularity, automatic slew, automatic spin-off, automatic lifting and concrete pouring and pile type display, etc, The bus panel design is adopted to prevent misoperation; 9. The chassis can be equipped with transport legs (optional) and remote control operation to achieve easier and safe site transfer and transportation.
