Project tests are performed on pilot poles, equal for geometry and construction technology. The test, classified as destructive, involves an axial load that leads to rupture the complex pole-soil or it allows significant diagrams of failure of the head of the pole as a function load-time. The verification tests shall be performed mainly to control the correct execution and behaviour of the load. The axial load will therefore be equal to 1.5 times the load project.
The SPCP1 system includes a hydraulic pressurization unit, connection hoses, ram cylinder, swivel head. The system is configurable depending on customer’s needs, on the kind of test, on the load to reach and on the ease of transport. The pressurization system may be manual, with a control hydraulic triphase power unit or with an internal combustion engine.
All units can handle different pressurization cylinders through systems of fitting. The thruster cylinders are made of aluminium to allow a better handling in the worksite. The configuration of the cylinder provides the assembly of leveling heads in order to improve the adhesion of the jacks on the pole and on the contrast structure.
The component, also allows the submission of the jack on peak loads that may prove a malfunction.
The system is composed of flow control valves, flexibles with quick release couplings and a pressure reading gauge. The gauge is available in both analog and digital version.
