Handling technology for electrical engineering and switchgear

In electrical production the weights are rarely in the critical range and the requirements high nonetheless: enclosure panels, transformers and battery modules are heavy, their attachments delicate – and between them lies production to a cycle.

Capacity at the assembly station
120 kg
Height of an enclosure housing

Torque at the bolted joint
60 Nm
01 — Applications

Heavy and delicate at once – that is the combination.

Typical handling tasks in Electrical and electronics — and what they demand technically.

01

Assembling enclosure panels

Uprighting side and rear panels, guiding them to the frame and bolting them – painted surfaces that take no scratches.

02

Fitting mounting plates

Entering populated mounting plates into the enclosure, held level, without knocking the fitted components.

03

Setting transformers

Joining compact, very dense parts into housings and frames – heavy relative to their size, with an offset centre of gravity.

04

Inserting battery modules

Entering modules into racks and housings, with fine positioning and without contact to the terminals.

05

Bolting without reaction

Absorbing tightening torques above 40 Nm through a torque arm instead of passing them into wrist and shoulder.

02 — What matters

What Electrical and electronics demands of handling technology

The load is manageable, the geometry is not

An enclosure rear panel weighs forty kilograms – carryable if it were compact. But it is two metres tall, painted and has to be guided vertically to the frame. The need lies exactly in that combination: not in the weight but in the fact that one person cannot grip the part so that it stays in position and the painted surface stays untouched.

ESD and surface determine the mount

In electronics production, conductivity requirements apply: mounts, handles and wheels are made from conductive materials so no charge builds on the part. At the same time the surfaces are delicate. Together that leads to cup and clamp pads of conductive polyurethane – a design that has to be specified from the start and is not retrofitted later.

Bolting belongs to the workstation

After joining comes bolting, and tightening torques above about forty newton metres pass as reaction into wrist and shoulder. A torque arm on the same device absorbs it: the tool hangs, the operator only guides. That keeps the station one unit instead of a lifting aid plus a separate tool balancer – two devices at one station are rarely a good idea.

05 — Frequently asked questions

Frequently asked questions from Electrical and electronics

From what weight is a device worthwhile here?

Earlier than elsewhere. Because the parts are large and delicate, the need often arises at 20 to 25 kg – not because of the load but because one person cannot hold the part in position. The key indicator method reflects that through posture and execution conditions.

What has to be considered in ESD areas?

Every contacting and load-bearing part has to be conductive and included in the earthing: pads, handles, wheels and the path from the device to the hall floor. That is a standard design but has to be explicitly required – retrofitting is laborious.

Can we use the same station for different enclosure sizes?

Yes, via adjustable cup arms or a clamping width with detents. We size the range from the smallest and largest format occurring – in between it changes over without tools.

How is it with battery modules?

There safety is added to handling: no contact with the terminals, defined insulation at the mount, no jamming while entering. We work with positive mounts on the housing and a fine positioning that handles the last millimetres without force.
