Seit über 50 Jahren ist die Firma HEDI Kabeltrommel Hersteller und steht für Qualität Made in Germany. Gehen Sie mit uns auf Zeitreise und erfahren Sie weitere Hintergründe zu den Produkten und deren Entwicklung.


1970 - Company formation

Founding of the company as a sole proprietorship by Helmut Diebolder in Osterberg. Field of activity: Contract manufacturing of machine controls.

1972 - Electrical installation company

Conversion of the company into an electrical installation company with around 20 employees.

1975 - The first cable reel

Helmut Diebolder's first in-house product is a cable reel. The construction, which is protected by international patent law, is in such great demand that the premises soon no longer suffice for production. The production and storage area is tripled.

1977 - Foundation of the HEDI GmbH

Foundation of HEDI GmbH in October. The name “HEDI” comes from the first letters of the company's founder, Helmut Diebolder.



1980 - Move to Babenhausen

After the production site in Osterberg could no longer be expanded meaningfully, a new, modern industrial plant was built in the then newly emerging industrial area in neighboring Babenhausen.

1985 - Winner

A cable reel newly developed by HEDI is the only one of 16 products evaluated to receive the test grade “GOOD” from the Stiftung Warentest.

The company HEDI now has 60 employees and a new warehouse with an area of ​​1,500 square meters is being built.

The free production areas at the location in Osterberg are used to set up the second mainstay, the cable assembly. Cable harnesses and electrical assemblies are produced there for industrial customers.



1993 / 1994 - Growth

The cable assembly area is growing rapidly and the HEDI production program is also being expanded to include socket distributors and industrial drums.

1994 - Managing director growth

Robert Diebolder is appointed managing director.

1995 - Location expansion

The company now has 80 employees and has to expand its location due to the high demand.

1998 - ISO-certified

HEDI successfully implements the quality management system according to ISO 9001.



2002 - Cable reel development

For the production of the newly developed cable reel series StarLite, Primus and Professional, a further production hall with goods issue warehouse is being built. The new cable drums are now manufactured on a highly automated production line.


The cable assembly area is being expanded and the production areas are being renovated.

In addition, a new product line with machine lights is launched and sets new standards in terms of price-performance ratio.


At the turn of the year 2006/2007, the company's founder, Helmut Diebolder, left the management team, but remained with the company as a partner and consultant. Robert Diebolder is now the sole managing director.

2008 / 2009

Introduction of the new socket distributor series HEDI e.STATION and m.STATION.

In addition, the cable assembly production halls and parts of the warehouse will be energetically renovated during these years.



2010 / 2011 - Entry into LED-technology

HEDI enters the LED technology.

The first machine light HEDI LEDpro! with the associated cooling technology for high-performance LEDs was developed and launched on the market.

2012 / 2013 - New measure

Encouraged by the outstanding success of the LEDpro! machine light was devoted even more intensively to LED technology and the next LED lighting product was developed.


The CUBE sets new standards in the field of work lights.



2013 / 2014 - Modernization

The old office building from 1980 is demolished. A new, modern and larger administration building is being built so that there is enough space for the next steps in growth and restructuring.

Our own combined heat and power plant with natural gas technology goes into operation at the same time. We generate our own electricity as required and use the resulting heat in our buildings.

2016 – Innovation

HEDI develops an absolute product innovation - two products in one:

The HEDI distributor LED.STATION!

With this, HEDI has established a completely new product category on the market with the distribution station including light function. The development team succeeded in integrating the light module perfectly into the housing design.



2017 / 2018

Introduction of the new machine and workbench light HEDI LED.ZOOM. For the first time, a lamp was developed with it that has a magnifying function and two integrated lenses.

This is another path in the lighting sector.

2018 - Generation 7

The latest and seventh generation of cable reels from HEDI was presented for the first time at the trade fairs in Cologne and Frankfurt.

The innovative and well-engineered product was developed as an all-plastic cable reel and thus corresponds to current and future safety standards and requirements of customers and users.

So that the new series can be produced, investments were made in further machines and an additional production line was built.



2020 - A new hall is being built

In order to be able to further expand and improve our two mainstays, the foundation stone will be laid at the beginning of 2020 for our own and larger production hall for the areas of cable assembly and control cabinet construction.
