SANY
As a high-torque heavy-duty rotary drilling rig, it specializes in large-diameter and ultra-deep pile foundation construction. It features strong power, stability, and reliability, and is suitable for heavy-duty engineering scenarios such as bridges, high-speed railways, large-scale buildings, and super high-rise pile foundations. It is highly adaptable to overseas large-scale infrastructure projects. Its core advantages are as follows:
Ultra-large torque + ultra-deep drilling depth, leading heavy-duty construction capability: With a rated output torque of 405kN·m, it can handle complex geological conditions such as rock formations and hard soil layers. The maximum drilling diameter reaches 2800mm, with a friction rod drilling depth of 106m and a machine-locked rod drilling depth of 87m. A single equipment can complete large-diameter and ultra-deep pile foundation construction without the need for multiple equipment cooperation, greatly improving construction efficiency.
Strong pressing force + high pulling force, smoother drilling in complex geology: Equipped with 340kN strong pressing force, 380kN high pulling force, and a power head with adjustable rotation speed of 5-25rpm, it fits the hole more closely during drilling. When encountering hard rocks or boulders, it is easier to pull out and get out of trouble, effectively reducing the problems of stuck drilling and hole deviation, and ensuring higher construction stability under complex working conditions.
Large-tonnage chassis + wide deployment, more stable overall support: The overall working weight of the machine is 131t, and the chassis can be deployed in a wide range of 3500-4900mm. The crawler has a large supporting surface, and is equipped with a mast adjustable by 4° front and rear / ±3° left and right. During ultra-deep hole construction, the machine body does not shake, the drilling verticality is higher, and the pile foundation construction accuracy is more guaranteed.
High-power original power, strong adaptability to overseas working conditions: Equipped with Isuzu 6WG1 original high-power engine, with a power of 377kW and a displacement of 15.68L, it has strong power output and more reasonable fuel consumption. The core power components are mature and durable, adapting to fuel standards and construction environments in different overseas regions, ensuring high equipment attendance and fewer later failures.
Heavy-duty hoisting system, more efficient hoisting operations: The main winch has a lifting force of 400kN and the auxiliary winch has 105kN. Equipped with large-diameter steel wire ropes, it has fast lifting speed and strong load-bearing capacity. During construction, the hoisting of drill pipes and the lowering of steel cages are smoother, which greatly shortens the auxiliary operation time and makes the overall construction rhythm more efficient.
Humanized design, more convenient operation and maintenance: Equipped with a large-view intelligent cab, the operation interface is simple and easy to understand, greatly reducing the intensity of manual operation; core pumps, valves, and filters are centrally arranged, and maintenance spaces are reserved for key parts. When there is no professional maintenance team at overseas construction sites, daily inspections and parts replacement can also be completed quickly, resulting in lower maintenance costs.
