Description
The apparatus automatically compacts the sample and stops after the preset number of blows. The mould is held in position by a quick and practical clamping device. The trip mechanism is arranged so that the sliding hammer falls at the same distance for every blow. The compactor includes the laminate hardwood block and vibrated concrete base 450x450x200 mm.
All moving parts are protected with safety guard, which stops automatically the compactor when opened, and the control panel is fit with an emergency stop red button, all conforming to CE prescriptions.
The compactor can be factory installed inside the 76-B4000/CB Noise reduction and CE security cabinet. See accessories.
