50-C1701/FR - DUPLEX - Parallel and orthogonal testing mode - High stiffness 350 kN cap. flexure frame with loadcell and connection kit for separate control console. Upper and lower rollers not included.

Дивитися повний опис

This high stiffness flexural frame has been designed to have a double testing mode: parallel and orthogonal.

Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e.g. fiber reinforced concrete (FRC) and sprayed concrete. These tests are significantly affected by the actual frame stiffness therefore the relevant international Standards state stiffness limits which are exceeded by this new model (better than 200 kN/mm). This remarkable result comes from the frame sections but it is also derived from the particular layout which keeps the specimen aligned with the frame crossbeams maximizing structural rigidity.

Orthogonal mode is meant to be used to test long specimens having more than 880mm length.

The horizontal daylight accommodates large specimens (slab, flagstones), concrete beams and kerbs long up to 880 mm.

The frame is fitted with high precision load cell (recommended for FRC testing), with piston travel limit switch and connection kit to the control console. Bearers not included. See accessories.

The frame includes two rulers, two additional rulers are available on request. Rulers with graduations in inches are available on request.
