2019 SR285 Large-Scale Hydraulic Rotary Drilling Rig for Major Infrastructure & Bridge Projects

Application

The sany sr285  has the advantages of strong power, strong stability, efficient construction capabilities, easy operation, convenient maintenance, high-quality manufacturing technology and reliability. It is an excellent tool widely used in earthwork projects.  

Features

1. Extraordinary Core Drilling Capacity
Equipped with a 285kN·m high-torque power head and a 300kW high-performance engine, it provides stable and strong power output. The machine boasts 260kN crowd force and 335kN pull-up force, enabling efficient and smooth drilling of large-diameter and ultra-deep piles, with outstanding adaptability to hard rock and complex geological layers.

2. High-Efficiency Construction Performance
Featuring a high-speed heavy-duty main winch and an optimized fast soil-dumping system, it significantly shortens single construction cycles. The adjustable rotation speed (5-24rpm) can be precisely matched to different geological conditions, maximizing drilling efficiency and shortening overall project construction period.

3. Heavy-Duty & Ultra-Stable Structural Design
Built with a super-heavy-duty crawler chassis and high-rigidity box-type mast, it has a low center of gravity and excellent operational stability, ensuring safe and stable operation under high-intensity working conditions. Wear-resistant and high-strength key components greatly extend the service life and reduce equipment failure rates.

4. Intelligent & User-Friendly Operation System
Configured with an advanced HD intelligent touch control panel, it supports real-time monitoring of working parameters, fault self-diagnosis and one-key precise operation. The ergonomic sound-insulated cab with comfortable seating and flexible control handle reduces operator fatigue, suitable for long-hour continuous construction.

5. Flexible Mobility & Convenient Transportation
Adopting a telescopic crawler chassis design, it offers flexible movement and steering on construction sites, adapting to narrow and confined working spaces. The compact whole-machine layout allows for integrated transportation without large-scale disassembly, simplifying site transfer and reducing transportation time and costs.
