As one of the leading manufacturer of motorised cable reels, spring cable reels and slip ring assemblies Hartmann & König Stromzuführungs AG supplies its customers with technologically advanced energy and data transfer systems
Spring cable reels - often called spring driven cable reel or spring operated cable reel - serve as reliable energy and data transfer systems for the orderly winding of flexible cables, hoses or ropes.
Spring driven cable reels are best suitable, in comparison to motor driven cable reels, for smaller cable cross sections, limited installation space, shorter transfer distances as well as for lower travel speed and acceleration. So, they are ideally for continuous operation (100% ED) in industrial applications for a wide range of demanding lifting and logistic tasks.
With regard to quality we make no compromises: All series and sizes of our spring cable reels are equipped with extremely rugged and durable reel bodies and slip ring housings made from galvanised steel sheet.
In addition to a broad range of our standard cable reels within the scope of our 48-hour express delivery programme we offer and design a huge variety of special spring driven cable reels according to customers‘ requirements and tasks, for example with reinforced spiral or cylindrical winding spoke reels or outside of the reel bodies arranged spring assemblies. These spring cable reels are suitable for higher tensile forces and longer distances of more than 60 metres.
The mechanical drive itself is realised via spiral leaf springs made of a high-quality texture-milled spring band steel, guaranteeing an average of 100.000 spring deflections at high levels of functionality and a long service life.
By consistently using screwed reel bodies and slip ring housings made from deep drawn, galvanised steel sheet as well as special double-layer coatings according to customers‘ wishes we ensure a maximum corrosion protection for industrial and maritime surroundings.
We’ve extended our 48-hour express delivery programme for spring cable reels. Now we provide all express cable reels also with payout "right" - in proven quality and for the same price conditions like our spring driven cable reels with payout left. In only 48 hours ready for dispatch after receipt of order!
Moreover, Hartmann & König supplies its customers the pre-assembled main accessories such as ratchets or roller yokes for spring cable reels with payout right also within 48-hours.
Hose reels transfer different liquid and gaseous media, such as water, air, gas and oils, to mobile consumers. They ensure an orderly winding and unwinding of non-deformable, flexible rubber spiral hoses or fabric hoses. The design of our hose reels is as robust as of our spring cable reels. Application fields for hose reels range from emergency vehicles (e.g. fire brigade) and the entire sector of mining to numerous industrial applications.
Depending on the application requirements we manufacture hose reels with spring drives and motor driven hose reels. Instead of the collector, a rotary feedthrough for air, water, gas, oil, etc. is installed. Rotary valves in a standard design are suitable for air and water up to a maximum of 10 bar.
In addition to our broad range of standard cable reels we offer and design a huge variety of special spring driven cable reels according to customers‘ requirements and tasks, for example with reinforced spiral or cylindrical winding spoke reels or outside of the reel body arranged spring assemblies. These special types allow higher tensile forces as well as longer travel distances of more than 60 m.
The ratchet ensures a defined cable length, by default with one notch per rotation. Several ratchets can be installed on request. The ratchet also ensures the strain relief of the cable during the operation.
The roller yoke is rigidly installed to the fixing flange. The roller yoke ensures the even winding and unwinding of the cable and, at the same time, it prevents the cable from „jumping“ over the external shield of the reel. The roller yoke is fitted with plastic rollers which preserve the cable and also make sure that, up to certain extent, the cable can be unwound sidewards.
The rotating ceiling attachment has a swivelling range of 300° and a stop. It is used for ceiling mounting, for example in workshops or automated facilities, and covers a maximum working range of 300°.
The rotating wall attachment has a swivelling range of 150°. It is used for wall mounting, for example in workshops or automated facilities, and covers a maximum working range of 150°.
Our fixed attachments can be used for ceiling and ground mounting, for example in workshops or automated facilities in order to cover a maximum working range of 150o .
The cable pulling grip ensures the strain relief for the cable at the feed point. The surface clamping prevents any point loads on the cable. It preserves the cable sheath and extends the cable‘s service life. The 800 mm long, galvanised cable pulling grip is adjusted to the cable diameter and, for safety reasons, it is calculated with 3 times the maximum tensile force.
This switch is used for monitoring the reel positions „full“ and „empty“ as well as for other monitoring functions (it is not a safety switch.) Alternatively, other limit switches, proximity switches or transmitters can be installed.
Thermally controlled stationary heaters at various output levels. Insulated installation in the slip ring housing. We recommend that a heater is installed in locations where low temperatures can occur or where the temperature fluctuates across a very wide range (within a short period of time).
Our commitment to quality “Made in Germany” begins with a professional initial consultation, includes development and production with a high vertical range of manufacturing at our company’s headquarters in the southwest of Germany, and continues long after the final delivery.
We adhere to national and international regulations and manufacture our products in accordance with processes – keeping an eye on customer satisfaction at all times. We have been certified to DIN ISO standards since 1997, and are currently certified to 9001:2015. This guarantees the highest quality standards and enables us to fulfil the requirements of our customers – which include large corporations and SMEs – as effectively as possible.
Our outstanding technical competence in the area of energy delivery to mobile consumers is based on more than 70 years experience in the development, production and installation of cable reels and slip ring assemblies. We support our customers with a dedicated team of engineers and designers, who develop solutions for the most challenging applications.
