Half a century of research and practical experience in the concrete block / paver industry led to this very mature concept. Model 875 is the answer to continuously increasing expectations in trouble free high speed production, permanent high product quality, product variety, high comfort in operation and maintenance of the plant.
The clearly structured design of the machine shows the innovation that was realized in this top model. Many features which made its predecessor to a highly ef? cient machine and the consequent improvements - based on experiences with our satis? ed customers - are incorporated in this machine.
Some mechanical highlights: maintenance-free hinge bearings on the hydraulic cylinders and driving rods, screwable straps on lever arms for easy exchange of bolts, extension of guide bearings for absolutely parallel and tilt resistant lift movement of mould and tamper head.
For increasing production capacity ZENITH Model 875 allows the use of production pallets with a maximum size of 1.400 x 1.400 mm. A new 2-part vibration system was developed which includes the frequency-controlled motor vibrators that have proven their dynamic qualities and easy maintenance worldwide. To minimize cycle times and to optimize the production process, the hydraulic system and electrical equipment were once more improved in close co-operation with the respective ? eld leaders.
The four main movements – mould lift, tamper head lift, drive of feed drawer backing concrete, drive of feed drawer facing concrete - are controlled via HNC control circuits. The specially designed open and closed-loop control algorithms guarantee quick and precise work-movements with low wear inside the machine. To further increase the capacity of this hydraulic control, an accumulator buffer can be integrated optionally. State of the art PLC controls and a process visualization system complete the pro? le of the machine and the respective plant.
