Product Description

It is used extensively in large road construction projects and has gained considerable importance in recent years. This apparatus, mounted on a rolled steel joist cantilevered from the back of a truck or fitted to the underside of a mobile frame, is used to determine the bearing capacity of soils quickly and efficiently.

This in-situ testing method, using piston penetration, is useful for determining the load carrying capacity in the field when the in-place density and water content are such that the degree of saturation is 80% or greater. It is also suitable when the material is coarse-grained and cohesionless, so that it is not significantly affected by changes in water content, and when the material has been in place for a considerable period.

Similar to the above, the unit is also supplied with a bench mounting type motorized load frame of 5000 kgf capacity, in place of a hand-operated load frame.
