Laempe & Mössner: Strong arms

Support arm systems are an important component in the human-machine interface. They are the link between machines or plants and the wide range of control and operating devices that are themselves accommodated in various types of operating housings. When it comes to configuring machinery, a growing number of mechanical engineers are starting to recognise the benefits of standardised, end-to-end solutions from a modular system.

“We use the new modular support arm system from Rittal because it enables us to implement all our operating concepts using just one system.”
Andre Klavehn, Laempe & Mössner

One particular application at Laempe & Mössner perfectly illustrates the kind of solutions that are in practical demand. The Barleben-based mechanical engineering firm uses support arm and operating housing systems from Rittal to ensure its core shooters – which are used to manufacture the sand cores that create cavities in cast parts – deliver an excellent overall quality standard.

Loads of 60 to 180 kg

The company uses the CP 120 support arm system from Rittal to fit Comfort Panel command panels to its machinery. This solution comes from the manufacturer’s new modular support arm system, which features a standardised design for loads of 60, 120 and 180 kg – each based on a support arm length of one metre.

Intuitive operation

The support arm system is extremely easy to install. The three different sizes are compatible and, when required, can be combined by using system adaptors. Once fitted, a support arm is also very easy to adjust when machinery is being installed or operated. All users need to do is remove a cap on the wall-mounted/top-mounted joint or on the angle piece between the support arm elements in order to access the two adjusting screws. The rotation range of the support arm can also be restricted just as easily, via an additional screw on the turntable.

Optimum position for signal lights

The design details of the support arm system also offer advantages. For example, the angle pieces that link the horizontal part of the support arm to the vertical part are available with an integrated fixture for signal lights. The advantage of this detail is that it ensures the machine operator can see the light from virtually any position. Standard signal lights can be installed in the integrated fixture in a matter of moments, without the need for any additional machining such as drilling or milling.
