Optimum bucket shape for rock and stone quadrants

Only the most powerful and efficient construction machines are used in quarries and gravel pits. They only achieve their full potential through attachments that meet the high requirements. For its work in earthworks, gravel pits and quarries, the Austrian company Flatscher relies on Rädlinger Maschinenbau excavator buckets which are specially tailored to the hard and demanding work in the extractive industry in terms of their design, materials and shape.

In comparison with conventional backhoe buckets, the Rädlinger heavy duty bucket and stone placing bucket are characterised by an exceptionally robust design. In the standard design, the buckets have protective hardfacing on the blades and side cutting edges, as well as wear strips that protect them from wear and tear. The shape of the tools is particularly decisive for the optimum detachment and movement of earth, rocks and stones. The current appearance of the heavy duty bucket, which is popular amongst professional users due to its filling behaviour, was developed over years in close collaboration with the industry. The rear-reducing bucket body and the deep side cutting edges were, therefore, taken on in the development of the stone placing bucket. So that it can take up and place very large rocks and blocks of stones, this bucket has a blade that protrudes far out in front and stone-laying protrusions on the base of the bucket.

Flatscher now uses three of these stone placing buckets, attached to CAT construction machines. Due to the large opening angle of the bucket, a large bearing surface is created, so that even large rocks can be taken up without tilting the bucket. “With this special shape, our workflows operate smoothly and damage to the buckets is less frequent,” says Bernd Flatscher, Managing Director and owner of the Austrian family company, which is in its second generation.

Taking the individual needs and requirements of Flatscher into consideration, Rädlinger Maschinenbau designed the three stone placing buckets in different sizes. Flatscher uses the smaller version primarily for stone-placing work on construction sites for earthworks and road construction. It has a cutting width of 1300 millimetres and a capacity of 1430 litres. In the two larger versions that are used in quarries, the cutting width is 1500 millimetres and the capacity 2300 litres. “The employees of Rädlinger Maschinenbau take customers’ requirements seriously. This allows optimum product solutions to emerge from the cooperation,” Bernd Flatscher explains his decision in favour of the Rädlinger attachments.
