Installation: The drop hammer should to be fixed on a massive concrete block of 70 x 70 x 60 cm in such a manner that the rails are absolutely perpendicular.
Procedure: The sample to be investigated is placed in the plunger assembly, consisting of two steel rollers (height: 10 mm; diameter: 10-0.003/-0.005 mm; hardness: HRc 58-65; polished surfaces ra=0.08 μm), a hollow steel collar (Ø16 mm; height: 13 mm; polished bore of 10+0.005/+0.010) and a centring ring for fixation. The assembly is placed onto a small anvil 26 x 26 mm.
Standard Accessories: 1 set steel rollers 1 pc small anvil 1 pc centring ring 4 pcs spoons 1 set steel collars 1 ea. weight 1, 5, 10 Kg 1 pc centring plate
Optional Accessories: In order to protect the operator against any possible splintering, a protection case, made of wood, is highly recommended as well as a suction device, removing hazardous explosion gases. Protection cases (part no. 782-1015) and suction devices (part no. 782-1059) are available as an option.
