1. INTRODUCTION
NOTE:
The present manual is updated for the product it is sold with in order to grant an adequate
reference in operating and maintaining the equipment.
The manual may not reflect changes to the product not impacting service operations.
The SPEEDLOADER tester is a machine used for road testing lab. The CBR and Marshall tests, Indirect
Tensile tests, Quick Triaxial tests, Unconfined and Uniaxial soil tests, and all tests that can be performed
under displacement control are all possible with the 50 kN capacity and the fully variable test speed of
0.2 to 51 mm/min. To meet the needs of either the field or the central laboratory, the machine can be
fitted with analogical or digital load/displacement measurement systems as well as dedicated
accessories.
The rigid two-column structure of the SPEEDLOADER tester includes an upper cross beam that can be
adjusted in height. The load jack, DC motor, and controls are integrated into a base cabinet with a
unique design. The machine's processor, with a memory up to 300 tests, gathers and processes test
data.
The user can control the test speed with the new Automatic Variable Speed 50 kN Load Frame, which is
easily adjustable and displayed on the digital display. Furthermore, the test stroke can be predefined at
the start of the test with an automatic stop, preventing overloading of the device and the test subject
and ensuring operator safety. This significant element also allows the operator to calibrate the machine's
speed using micrometric adjustments. The lower platen's motion direction is also showcased on the
display. Two operating leds—one for machine switched on and the other for travel direction—and an
emergency button also are installed on the front panel.
Main features:
The firmware provide the digital speed control and a number of important test functions as follows:
Closed loop speed control
CBR and MARSHALL test speed can be selected by default.
Other testing speeds (Custom) between 0.2 and 51 mm/min, can be easily set.
Selection of maximum platen displacement.
The automatic stop of the machine avoids machine and specimen overloading, thus assuring
operator safety.
Rapid approach function, to reduce the testing time.
Rapid platen return to speed up the platen base return at the end of the test.
Speed calibration function by firmware. The test speed is originally factory calibrated using a
polynomial interpolation. A test point is provided to verify the speed with a standard tachometer.
Emergency stop button as required by the CE prescriptions.
