EN Automatic Concrete Machine (2000 kN (450000 lbf))

VJ Tech compression machines are manufactured to strict quality control systems and EN12390-3 & 4 standards to ensure reliability. All frames are of heavy duty welded steel construction and supplied as standard with a rapid approach pump. The machine, together with the digital readout unit is works calibrated and supplied with certificates. The integral load pacer, together with a large LED error band display, enables the operator to maintain accurate pace control. The optional distance pieces (30, 50 & 90 mm height and 205 mm diameter) are designed to reduce the clearance of the upper platen to the top surface of the specimen. The VJ Tech range of concrete compression machines may also be used for strength testing rock samples in Hoek Cells. Note: The VJT51-xxx range of Concrete Compression Machines & Accessories replaces the VJT6000 series
Part Number : VJT51-2011
