Improve construction safety SANY SR250 Rotary Drilling Rig

Advantages of Power Drilling

250kN · m high torque power head, sufficient pressure, strong drilling ability in pebble layers, moderately weathered mudstone, and limestone, suitable for complex composite formations in China.
The main winch merging and rapid lifting technology has a maximum winch speed of 63m/min, fast lifting and lowering of drilling buckets, and a comprehensive construction efficiency about 15% higher than similar models.
The engine hydraulic system is precisely matched, and the load sensitive hydraulic circuit reduces fuel consumption by 5-10% compared to the old model, resulting in lower long-term construction and operation costs.

Structure and stability

The SY460R has a widened and wide chassis, with a total weight of 74 tons and a low center of gravity. It has good anti overturning performance for deep hole and large aperture operations, a large track contact area, and is not easy to sink on soft ground.
The mast is made of high-strength box type steel, with a strength increase of 30-40%; Reinforced slewing bearing, high durability for heavy-duty slewing; Key welding seam robot welding, non-destructive testing, low failure rate, and long average time between failures.
Standard friction type drill rod, optional extension rod, maximum drilling depth of 70m, aperture of 2.3m, covering the vast majority of municipal, building, and small and medium-sized bridge pile foundation projects.

Intelligent and secure configuration

The main winch is equipped with ground protection and automatic lowering. When the drilling bucket falls to the bottom of the hole, the oil will automatically cut off, preventing tangled ropes and damage to the steel wire rope, and extending the service life of the steel wire rope.
Cockpit mast anti-collision limit, auxiliary winch over roll protection, multiple limit switches, all-round safety protection.
Equipped with the Root Cloud remote intelligent platform, real-time monitoring of fuel consumption, working hours, and equipment failure warnings facilitates project equipment management and rental control.
A spacious and comfortable driving cabin, with a simple human-machine interaction system, low difficulty in getting started, and user-friendly for beginners.
