The dynamic probing rig LMSR-SPT-VK is a highly functional soil investigation machine, easy to transport due to the folding mast feature. It is versatilely suitable for working in confined spaces and is displaced in outdoor terrains by hand. It features a three-legged foot with crank legs for solid erection on site. The dynamic probing rig LMSR-SPT-VK can be used for soil-bearing capacity tests, compaction tests and for soil sampling. Dynamic probing standards DP-L, DP-M, DP-H, DP-SH as well as SPT can be carried out. Adaption for different drop weight masses is realized by removing or adding weight bodies at the drop weight mechanism. Drop height can be varied between 50 and 750 mm by means of an adaptor bracket. The integrated three-legged foot with crank legs allows for soil sampling at ease. The dynamic probing rig LMSR-SPT-VK is driven by a 4-stroke combustion engine and needs no additional power sources in the field. The drop weight carriage is lifted and lowered on the mast with an integrated rope winch.
