Bucket dredger for small, medium and large production, adapts to all types of clay, sand or others. This machine is basically composed of a trolley that transports the boom, mounted on a translation bridge, on which the different mechanisms are fixed and driven by several gearboxes.

The chain with its buckets is driven by a geared motor direct to the axle of the driving wheels, giving it a smooth, regular and silent movement. The bucket chain is made of hardened steel with high structural and wear resistance. The buckets are made of stamped sheet metal and the parts that are in contact with the clay are made of wear-resistant steel sheet. The internal driving wheels of the bucket-carrier chain are machined toothed with teeth, fixed by means of screws for their replacement, forming a 120° gear with three sectors.

The movement of the bar-carrier is carried out by means of two geared motors with a frequency variator, designed to work at two main speeds, one for work and one for fast. The elevation and graduation of the different positions of the boom with its chains and buckets is obtained by means of a hydraulic unit formed by two pistons, a central one and positioning encoders. These are commanded by a PLC cabinet programmed with all the relevant devices for the control and safety of all machine movements.
