The jolting apparatus you described is a piece of equipment typically used for compacting or testing materials, such as in cement or soil testing, by subjecting a mold to controlled jolts. The apparatus has a rectangular table connected by two support arms to a spindle, located 800 mm horizontally from the table’s center. A motor-driven cam rotates at 60 rpm, causing the table to rise and fall freely, producing jolts. Each rotation of the cam corresponds to one jolt. A stroke counter with a micro switch stops the machine after 60 jolts. The table includes locating pins to secure mold compartments. The mold, surrounded by a hopper, can be rigidly clamped to the table. Operates on 220 V, 50 Hz, single-phase AC power. Supplied complete with mold and hopper.
