The range includes four models of 1000 kN and 2000 kN cap. All models are controlled by the new and sophisticated HPU 200 control unit and are complete with PC, upper and lower hydraulically operated jaws, complete set of grips for rounds and flats, transverse test attachment and high precision load cell providing high accuracy from the very beginning of the load scale.
Loading frame
The frame consists essentially of a robust four columns frame with three sturdy crossheads: upper is directly connected to the lower one by two main columns; the middle one, moving on two screw columns, can be adjusted through an electric motor by using the dedicated push button panel, in order to set the required vertical daylight both for compression and tensile tests; the lower is controlled by a simple effect piston centrally positioned. Jaws and wedge grips are included. The tensile jaws are operated by a separate Hydraulic Gripping System with dedicated a push-button panel. The compression tests are performed between the lower and the mobile middle crossheads, using the suitable accessories.
Power and control console - HPU 200
Control console HPU 200 features space-saving ergonomic design with small footprint and houses the hydraulic power unit, the electronic system and the PC to manage all the control functions.
Automatically performs steel tensile testing, compression, splitting tests, Elastic Modulus and Poisson's ratio determination on concrete specimens. See Accessories.
PC and software enable remote control of the complete system.
The system can be upgraded for a second frame connection and control by a special hydraulic valve system (70-T10/2F). Normally adopted to connect a concrete compression frame up to 5000 kN capacity, to perform not only compression, but other important tests as for example the Modulus of Elasticity, with the related software (model 82-SW/EM). Selection of the test frame via software.
