Pile Foundation Drilling Rig SR-515 SR-520 Small Piling Rig

SR-515 SR-520 Crawler Type Small pile foundation drilling rig is a kind of construction machine suitable for hole formation in building foundation engineering. Mainly suitable for sandy soil, cohesive soil, silty soil and other soil construction, widely used in cast-in-situ piles, continuous walls, foundation reinforcement and other ground foundation construction. This small rotary bore pile drilling rig drilling depth is 15-20m. Matching the different specifications of drilling tools, pile hole diameter range up to 500-1500mm.

Foundation Drilling Rig Main Features:

It has high drilling efficiency, flexible and convenient for moving and transporting to next working site, is a national high-speed rail construction-specific piling machinery equipment. This machine is applicable to soil, clay, fill soil, silt, silt layer, and some strata contain pebbles, gravel; widely used in high-speed rail trestle piles, slop shield piles, photovoltaic power station foundation pile, power grids, civil construction, new rural construction, municipal construction, landscaping and other projects.

Small Piling Rig Advantages:

Flexible: The whole tonnage is small, simple operating, moving fast, convenient transition.
High returns: Small investment, quick gains, economic advantages can not be replaced.
Technology patents: Patent uses a unique technology to achieve a small torque but big power characteristics, thus achieve a small piling machine to drill big piling hole.
