This is an important feature which facilitates easy insertion of tensile specimen from the front. This is extremely useful especially for heavy specimens and bigger capacity machines. In this type of machine the jaws and the inserts also can be easily removed by just pulling from the front. When the jaws and inserts are heavy, it is very difficult to remove them from the machine from upper or lower side. Hence this is an important feature from the point of view of easy operation.

Normally for standard Universal Testing Machines the jaw opening and specimen clamping is effected manually. But this becomes more and more difficult for the operator for higher capacity machines. Also the specimen clamping becomes operator specific in this case. Hence it is a better choice to go for hydraulic operation of jaws (closing and opening). In this hydraulic griping method, separate double acting hydraulic cylinders operate the jaws and the cylinder operation is just by pressing a push button. So the operator has to operate only push buttons, which are conveniently located on the machine, to operate the jaws. A power pack with oil tank, pump, motor, oil filler cum breather, oil level indicator, filter, relief valve is provided along with an electric motor to drive the hydraulic pump. In case of Conventional UTM, the specimens falls down after its failure during a test. However for the machine with Hydraulic grips, the specimen remains in clamped condition even after test is conducted. Operator can remove both the pieces from respective cross heads by pressing the push buttons.
