DROP TEST FACILITY  (9 M DROP AND 1 M PUNCTURE TESTS)
UN-YIELDING TARGET (UYT)
The UYT consists of a concrete block of 7m x 7m x 2.5 m (depth) (weighing more than 300 t) resting on hard rock. Fig 3 shows the layout of the UYT. Top MS plate of 3 m x 2 m x 280 mm thickness is provided which is embedded in the concrete. A square bar of 150 mm and 12 MB 200 I-beams are welded to the top plate bottom and acts as load spreaders. A 12 mm thick MS plate is embedded on the concrete block all around the top MS plate to cover the remaining area of concrete surface of 7 m x 7 m. Grout material is used between plates and the concrete block for better integration.

10 T CAPACITY GOLIATH CRANE
A 10 t capacity Goliath Crane is provided for shifting, lifting and dropping of the test specimens.
