Pile Foundation Drilling Rig
The FR800 Foundation Drilling Rig is a crawler-type foundation drilling rig designed for foundation engineering, large-diameter drilling and complex stratum construction. The maximum drilling depth is 100-800m, the drilling diameter range is 200-600mm, and it is equipped with 40T lifting force and 17600N·m maximum rotary torque. According to different stratum conditions, hydraulic rotary drilling, DTH hammer drilling or mud drilling can be adopted.
This machine is suitable for loose layers and bedrock construction, and can meet the construction needs of pile foundation engineering, building foundations, bridge foundations, mining engineering and other large-diameter drilling projects. Multiple drill pipe length configurations of 3m, 6m and 9m facilitate flexible selection according to site space and construction depth.

The FR800 foundation drilling rig can be used in the following engineering scenarios:
Suitable for various conventional strata. The power head outputs torque to drive the drilling tool to rotate, and different drill bits and drill pipe combinations can be selected according to stratum conditions.
In bedrock, hard rock and other strata, a DTH hammer can be configured for percussion-rotary drilling to improve rock-breaking capacity in hard rock strata. During actual construction, matching air compressors and DTH drilling tools need to be selected according to hole diameter, depth and stratum.
In loose layers, hole-collapse-prone strata or projects requiring mud wall protection, mud drilling can be adopted. By reasonably configuring the mud pump, drilling tools and circulation system, hole wall stability and cuttings removal effect are improved.

Before choosing the FR800 foundation drilling rig, it is recommended to confirm the target hole depth, opening diameter, final hole diameter, stratum structure, drilling method and on-site construction conditions of the construction project. For hard rock projects, the DTH hammer specifications and air compressor parameters also need to be confirmed; for mud drilling projects, a suitable mud pump and circulation system need to be selected according to hole depth and hole diameter.
In order to recommend a suitable FR800 configuration and provide an accurate quotation, please provide the following information: planned drilling purpose, maximum drilling depth, opening diameter, final hole diameter, main stratum conditions, drilling angle and expected purchase time.
