MS-398 and MS-398F Pro-Loader II Load Frame

INTRODUCTION

The MS-398 Load Frame is one of our most versatile testing
units. The Pro Loader II can be utilized for the following soil tests:
California Bearing Ratio (CBR), Unconfined Compression (UC),
Triaxial Compression, and Soil Cement. In addition, the following
Asphalt tests: Marshall, Lottman, TSR, IDT, SCB and Tack Coat shear
can all be performed. This unit also features strain rates – 0.02-
2.0in/min (0.508-50.8mm/min) – controlled to ±1% of set point.
Front panel controls allow the operator to adjust the direction
and speed of the platen, as well as select the strain rate. Sliding
the cross-arm up or down the coarse-threaded 1.25in (32mm)
diameter rods and tightening the nuts makes adjustment for the
wide variety of testing components quick and easy.
