Why needs the professional SPT Soil Investigation Geotechnical Drilling Rig?
The definition of SPT, is called for short of “ The Standard Penetration Test (SPT)”, which is widely used in mining, building industry, Foundation Engineering Construction, etc. Before the construction sections start up, we should work the soil sample well, to make sure the strength, force and velocity of the soil was tested from the SPT Analyzer. Which could bear the force of required building constructions on the ground.
Working Principle of SPT, Normally according on the needs of construction drawings, using a different size split barrel sampler sample tools like PQ, HQ, NQ, BQ, AQ, etc, through the wire-line from the top power-head of SPT drilling rig to penetrate certain standard depth required by the drawings, a string drilling to obtain soil samples.
RBSPT-500 SPT& Wire-line Core Testing Drilling Rig is our largest and most powerful Maximum Torque 15,000 Nm, also with max rotate speed 2400R/min, through the mechanical drive to achieve strong dynamic performance. That is the reason, RBSPT-500 wire-line coring rig could drill the coring size of “NQ-HQ-PQ with 1500m-800m-500m”. because the gear mesh could result in improved stronger engine power transfer compare the hydraulic drive machine, and also improve durability, less gear noise, save fuel as well. Perfectly for SPT soil sampling and rotary wire-line core drilling in any complex underground soil layers. Our SPT & Wire-line Core Test Drill Rig is the quality assurance for deep foundations construction so far in China.
Our SPT Soil Investigation Drill Rigs are designed specifically for geotechnical engineers and soil testing contractors. These rigs are compact yet powerful and include a 10-speed gearbox of the truck gearbox, a hydraulic cylinder driven mast which provides lift force (24Ton)52,896IB, and a high sped lifting winch( 8Ton)17,632IB for extremely fast rod extraction，Thrusting capacity(18Ton)39,672IB. Also included are a mud/water pump, pipe clamp, manual SPT hammer system and top-intake wet swivel.
Other key advantages on our RUNBAY SPT rig, which has 92KW engine, with 2400r/min, 4 cylinder engine with Turbo, we also got the Commins 4 cylinder engine 75kw with Turbo for your option, make sure the power enough stronger. and you don’t have to worry about the after-sale service and spare parts for the engine.
What’s more, RBSPT-500 RIG got the national patent in China, we have improved the traditional top hydraulic top drive to our current advanced mechanical drive mode. Which makes the big step on the drilling machine. It carried out the rig its not keep the powerful maniacal driving method, but also learn the hydraulic flexible driving method, the Patent No.National invention patent:ZL201510479602.4). It adopts AMT manual automatic transmission, 10 grade forward gears, and 2 grade reverse gears. Positive and negative switching is sensitive and convenient. Compared with the hydraulic transmission, and its transmission efficiency can be doubled, and the power consumption is reduced by 35%, which makes the machine more efficient and energy-saving. We got the SPT autohammer soil sampling system, which can be mounted on a small truck, on a trailer, or on rubber tracks.
Stronger and bigger SPT rig, always come up with extra excellent bits for extra hard rock, because if the bits are not durable, that will cause the even sometimes the unnecessary waste of labor, and affect working efficiency, so our RUNBAY also is a professional supplier of engineering piping, bits and tools let customer no worries service.
Our SPT soil testing drill rigs can do more than just standard penetration test with any soil conditions, They are perfect for carrying out in soils where it isn’t possible to bring out an undisturbed sample, such as in weak rock, silt, clay, sand, and gravel. …but also in hardest rock in deepest complex underground, like granite, domolite, etc pls see the below working video:
SPT & Wireline Core Test Drill Rig with the nick name “money-maker”, is the machine with most quick return rate, almost with one boreholes you could make all your money back. Which is the biggest money- maker, We are so proudest for our RBSPT-500 , just buy our SPT Soil Investigation Drill Rigs, then you will be a clever money-maker. Just Give us a call or send us an e-mail.
We are always happy to hear from you!
