Quick coupler systems for special requirements

Attachments can be fitted and changed quickly and simply with quick coupler systems. The really decisive benefit, however, is that the right tool for each application requirement can be attached quickly. This not only allows the range of applications of construction machinery to be extended, but also means that repair costs incurred as a result of the incorrect use of the attachments can be significantly reduced. Rädlinger Maschinen- und Anlagenbau GmbH has a wide range of quick coupler systems on offer. With three quick coupler systems, Rädlinger focuses on particular usage requirements:

The Rädlinger “SWP” quick coupler system is designed specifically for the hardest applications, e.g. in quarries. All parts subject to high stress, such as bucket bolts, hooks and unit faces are generous in their dimensions and made from hardened or wear-resistant steel. The interlocking in the bucket roof is done using fixed hooks and a mobile clamping device in the quick coupler system. The high surface pressure between the cable and the bucket roof hook and between the back unit faces of the coupler system and the stops on the bucket roof guarantee a tight fit. Laborious adjustment or readjustment is, therefore, not necessary. Additional safety devices reduce the risk of accidents and damages to the construction machine and the attachment tool.

The Rädlinger “Lehnhoff” quick coupler system is an all-rounder. In comparison to other manufacturers, the optimised Rädlinger version has hooks in HB 400 and a back wall with an adjusting plate, so that the fit can be adjusted precisely. These ideas for optimisation were incorporated into the technology from many years of experience in our own construction company. Thus, Rädlinger addresses a quick coupler system that is very common on the market and, with the improvements, raises the standard usual in practice. The quick coupler system engages in the shaft of the bucket roof with two receptacle claws. The interlocking is done by two crossbar bolts that engage in a block on the attachment.

With the Rädlinger “SWh/SWm” quick coupler system with bucket conversion, buckets can be fitted by direct attachment. The new purchase or conversion of attachments is, therefore, not necessary. The quick coupler system has a compact design. The mechanical interlocking between the bucket bolts takes place effortlessly and quickly using a reversible ratchet. For hydraulic interlocking, continuous pressure is applied to the hydraulic cylinder. An integrated stop valve on the cylinder provides additional security.
