Crawler Machine Lock / Friction Rod Piling Rig
Product Description
Overview
The YR75S Rotary Drilling Rig is designed for small-scale foundation piling, power pole foundations, and general engineering works. Its compact configuration makes it a practical choice for projects requiring flexible positioning and efficient operation within limited working areas. The rig offers a maximum drilling diameter of 1,500 mm and a standard maximum drilling depth of 15 m.
It can operate with mechanical interlocking or CFA Kelly bars, depending on the project requirements.
An optional telescopic chassis expands the machine width from 2,205 mm to 3,000 mm to improve stability and enables drilling depths of up to 20 m. Engine configurations can be tailored to meet the emission standards in your country.
Ideal for medium-sized projects, the YR75S combines power, efficiency, and portability, ensuring optimal performance in challenging conditions.
