The Marshall Stability Machine is used to determine the load and flow values of bituminous mixtures.The Marshall is composed of a robust and compact two-column frame with an adjustable upper cross beam driven by an electro-mechanical ram with a maximum capacity of 50 KN and a data acquisition and processing system.The Marshall Stability Machine can be hand operated by a lateral hand wheel for calibration purposes. The mechanical jack raises the lower cross beam at a constant speed of 50.8 mm/min.The limit switches are provided for both, bottom and top limit of travel.The Automatic measuring system consists of a 50KN capacity strain gauge load cell that is fitted to the upper cross beam to read stability values and 25 mm x 0.001 mm displacement transducer fitted to Break Head.The Manual measuring system consists of a 50 KN capacity load ring and dial gauge graduated 0.01 mm with 25 mm travel.Technical Features:-The vertical rise speed of the test apparatus tray:50±5mm/minMaximum movement distance of the test apparatus pallet:70mmWorking range of force value:0 - 50.00kNWorking range of displacement: 0 - 10.00mmMeasuring accuracy of force measuring device:±0.1kNDisplacement measuring device measuring accuracy:0.01mmWorking voltage:220V 50Hz ACSpecification of motor:220V, 0.37KW, 1440rpm, three-phase operationMaximum rated load:50KNUsing conditions: Ambient temperature 0℃-60℃ Relative temperature <85%
