ABSTRACT
The Cone Penetration Test (CPT) cabin as working environment, built on trucks, crawlers or Track-Trucks®, will more and more develop from a workshop into an office. Before, operators were mainly dealing with manual operations to keep the production going. Nowadays and in the future, it can be increasingly expected that time “on board” will be spend on design or other office-related work next to performing CPTs. This paper describes a system that has been designed to support this market development. By integrating the patented SingleTwist™ technology in a CPT cabin with the COSON continuous pushing system, an automatic and hands-free CPT machine is created. The assembly and disassembly of the CPT string takes place fully automatically. This paper describes the efficiency of the SingleTwist™ technology. The City of Rotterdam, the first owner of a Track-Truck with COSON-ST, deployed their system in different projects. One project is chosen to further elaborate on its advantages and experience in practice.
