 |
Machines with four columns prestressed frame
Standards: ASTM C39 -AASHTO T22 - UNI 6686, 1, 2 -
BS 1610 NF P18-411 |
Machines with four columns high stability and stiffness frame
Standards: ASTM C39 - AASHTO T22 - EN 12390
- BS 1881 - DIN 51220 - UNI 6686/3 |
General Description
These load frames are extremely stiff,
rugged and oversized to ensured the required high rigidity and
stability.The upper head holds the precision lapped ball-seating
and the compression platen.Compression platens are surface hardened
HRC 60 and ground. Design emphasis has been placed on simplicity
of construction and operation, so that our machines are durable,
easy to use and maintain, and designed for heavy continued use.The
M-Line compression testers are designed to conform to International
Specifications such as: ASTM, AASHTO, EN, BS, NF, DIN, UNI,
UNE, and are available in 1200 kN, 1500 kN, 2000 kN, 3000 kN,
5000 kN capacities, both hand-operated and motorized, at one
or two gauges, with electronic digital display measuring system,
and with automatic servocontrolled console with microprocessor.The
different versions provide the possibility to test cubes, cylinders,
and blocks. All the machines can be equipped with optional safety
guards. |
Hydraulic System
Piston has large diameter: this allows the hydraulic circuit
to work at low pressure with longer life of working components
and higher precision in the results.Piston is ground and lapped,
and a packing high quality set of three elements is utilized. Motorized
models foresee a dial device to visualize, pre-select and control
the flow allowing an uniform load rate as requested by Standards.A
fast approach ram action device is foreseen to avoid dead times
during stroke of the ram.The manual pump is two stage for fast
approach ram action and automatic change for test pressure.Power
pump is multipiston, assuring continuity of delivery.A movement
indicator visualizes instant by instant the piston’s excursion
during the compression test.A hopper is foreseen avoiding the
powder of the broken specimen to enter into the cylinder of
the press damaging the packing set. |
