These are hydraulic jacks with integral pumping unit. The hydraulic pressure gauge is of 15 cm dial mounted on the side of hydraulic jack. A detachable lever is provided to operate the pump. Face of the ram is flat.
Note: Hydraulic jacks of & 5000 KN capacity can be supplied with two speed pumping units. These jacks have lift to approximately 200 mm.
This is for estimating the bearing capacity of shallow foundations in situ and for the design of flexible pavement. In the test procedure a steel plate is subjected to gradually increasing load and settlements of the plates recorded. Maximum bearing capacity is noted as that load at which the plate starts sinking rapidly.

It has become recognized that is Testing Laboratory the best performance can only be obtained if all the springs of a uniform type possess the same mechanical properties. Special Testing Machine for dealing with tension and Compression Springs of helical pattern are to be made use of the machine of very simple designs used for statical tests on springs cannot be used for Compression and Tensile tests. Spring Testing Machine is an earnest effort in this direction. Machine enable load deflection tests of tension and compression springs to be carried out accurately and quickly.
The Cabinet contains the hydraulic unit the hand wheel of the pump and the release valve handle are outside the cabinet for easy operation. This compact base carrier two fixed upright and four horizontal plates. The first and the third plates with two small uprights from an adjustable frame. The second and the fourth plates are fixed. A square threaded wheel arrangements provided for adjusting the height of the springs.
A Bourdon type Gauge is fixed for direct load measurements. One fixed upright is graduated to denote the deflections or tension of the springs for direct readings. A thimble with on arrow mark is provided to facilitate the readings. The machine is capable of accommodating 8" length 1/2" dial. rod up to 4" dia. springs for tension, 6" length 1/2" dia. rod, 4" springs for compression. Scale graduation are made up to 15 cm.
Torsion Testing Machine is designed for conducting Torsion and twist tests on various metal wires, tubes, sheet materials. Torque measurement is by Pendulam Dynameter System. Torque ranges can be adjusted. Torque can be applied to specimen by geared motor through gearbox. Autographic recorder can be provided to know relation between torque and angle of twist on specific request. The Accuracy of the torque indication 1% of the true torque.
The Techno Tensile Strength is electrically operated and is used to check the physical impurities.
It is based on constant rate of transverse principal. The test specimen is held between the two grips, the upper one of which is connected to the load indicating arrangement while the lower moves down at constant speed with the help of a motor operated screw. The elongation is measured as the displacement of the lower grip.
