Wheeled constant energy dynamic penetrometer

The LM50 is a constant energy dynamic penetrometer on wheels. It comprises a pile driver on wheels, fitted with a motor as mechanical drive for the chain. Owing to its compact design, this machine can be used in poorly accessible places.

Its simple design makes it a very reliable machine which is easy to maintain. The adjustable dynamic probing system enables testing in DPL, DPM, DPH configuration, in accordance with the NF P 22476-2 standard.


The success of this device is also due to the design of its dynamic probing system which is equipped with a motor system that is not supported by the drive rod. Apart from this advantage, the support on the drive rod during driving is very limited (in accordance with the requirements of the standards). Moreover, movement of the hammer is free over the whole height of the mast, its travel per blow is not limited.


Applications :
– Dynamic penetrometer soil investigation in accordance with EN 22476-2
– Sampling by probing
