The GHT 4x4 is the total traction filter press with high productivity. The filter plates, which are hung from the upper beam, are moved automatically by a rapid shifting device equipped with a carousel system which reduces the filter press opening and closing sequence to the minimum. Four hydraulic cylinders placed on the plate pack corners ensure perfect operation and limited structural stress, even in the most unfavourable working conditions. Different from the traditional push-type systems, the “total traction” system does not transmit any stress to the upper beam, which is only subjected to weight of plates supported from it. In fact, the forces applied by the closing device are subjecting the tie beams to tension, which avoids stress on the frame and consequently, the risk of structural deformation. Effectively guarded moving parts and the use of state-of-the-art electronic interlock systems mean that the GHT 4x4 conforms to the highest operator health and safety regulations. Routine maintenance operations are simple, thanks to easy access to the filter plates, both for inspection and for filter cloth replacement.
