Chongda solar pile driver can drive the pile into soil or rock to support the solar panel for solar power station system and guardrail installation, the common application is for Photovoltaic panels installation
 
here are several type Photovoltaic rig, from manual rig, to semi-hydraulic pile driving machine to fully hydraulic drilling rig
 
Currently the full hydraulic piling driver is most popular rig in market
It can work with rotary head for auger drilling, also can work with Hammer to do hammering pile into soil directly
 
Chongda PV piling machine includes MCDPV-2,MCD130Y,MCD385Y totally four different model. It can be selected based on the pile shape and depth


 
Photovoltaic Pile Driver Configuration
 
Solar drill rigs including following main parts:
Track – for tramming and ground support during drilling or piling
Fuel tank – storing fuel for engine
Hydraulic tank – storing hydraulic oil for hydraulic system
Engine – Commins or Yuchai eninge to supply power for rig
Cooler – including engine cooler and hydraulic oil cooler
Battery – to offer the electricity for electrical system
Cover – to protect the key component from rain, dust etc.
Boom – for hold the mast to different position
Slider – to adjust the off ground clearance for drilling
Drill mast – hold the rotary head or hammer head for drilling
Rotary head – can do auger drilling and DTH percussion drilling
Hammer head – hammer the pile into ground directly


 
Solar Pile Drilling Method– totally three different drilling procedure for PV drilling as following
 
Auger Drilling
The pile driver drive the auger into soil directly by rotating, it is only for the soft ground such as soil, sand, soft clay.
It needs to use rotary top head
DTH Drilling
When drilling for hard formation like rock, hard clay. It impossible to break the rock by auger drilling or other type drilling to make pile into ground directly.
Rig has to works with air compressor together for percussion drilling. In this way, it can make a borehole firstly, then put the pile inside or concreting a pile.
Hammering
When it needs to install the solar pole in more efficienty way and have it stably installed, hammering the pile into ground directly is the best way.
In this way, it needs to change to hammer head( pile driver), Chongda Pile driver has very powerful impact power and high impact frenquenc
Solar Pile – for soft formation piling, it mainly use below 3 type pile
 
Auger Pile
It is used with rotary head for sild drilling
Common Pile Lengh: 1.5m / 2m / 3m
Common Pile Diameter: 150mm ~350mm
Stratum: Soft formation – soil, sand, clay
C Shape Pile
It workds with hammer head to penetrate into groud directly
Stratum: Soft formation – soil, sand, clay
H Shape Pile
It workds with hammer head to penetrate into groud directly
Stratum: Soft formation – soil, sand, clay
