H i-Precision K now-howS ervice132Dirt, dust, moisture...? So what!Whoever thinks that such high precision is sensi-tive, is in for a pleasant surprise: exactly the op-posite is true for the HKS rotary actuators. With working pressures of up to 350 bar, they require a strong, well-sealed housing. This also provides excellent protection to the interior. Our rotary actuators are therefore completely immune to dust, dirt, and moisture. It is therefore no won-der that one can rely completely on them evenunder the most difficult conditions, whether deepunderground in mines or 2,300 meters under sealevel. HKS rotary actuators again proved theirreliability in the raising operations on the Rus-sian atomic submarine Kursk.Our rotary actuators have also acquired an ex-cellent reputation where the highest levels ofcleanliness and hygiene are necessary. For ex-ample, their reliability is highly valued in the phar-maceutical industry and in food production be-cause of their cleanliness in operation.Precision at the limits of the possible The linear movement of the hydraulic piston is converted into rotary movement by means of multiple helical gears. This is the same principle a drill uses.The helical gears thus convert hydraulic pressure into very high torque levels. For rotary-lift combinations a linear movement is added to the rotary one.The principle is quite simple, however a great deal of precision is necessary to give our rotary actuators their function and well-known reliability. This precision lies at the limits of what is currently possible. We are therefore rather proud that we are able to reduce the tolerance in the angle of rotation in our actuators to less than 10 angular minutes. More important for practical use, however, is the fact that all the modular units in our rotary actuators can be exchanged within minutes, if necessary.HKS rotary actuators have it allOutwardly hydraulic rotary actuators do not seem all that impressive. You just cannot see what is inside them. No onewould suspect that our strongest model could easily move 20VW Golfs from one side to another.Our hydraulic rotary actuators are compact units which can generate very high torque in very little space with hydraulic pressure. And because they are extremely precise and easy to control, in spite of their enormous strength, HKS rotary actuators have conquered nearly every field in which limited rotary movement with high torque is required.1Unobtrusive – but strong and reliable: HKS rotary actuators for mobile applications.3Raising the Russian atomic submarine Kursk from the BarentsSea. HKS rotary actuators were used.Precision without compromise: The interior of an HKS rotary-lift combination.2Leonardo da Vinci wanted to build a flying machine using helical gears.123Construction machinery is one of the traditional uses for hydraulic rotary actuators. In pile drivers and pulling machines, for example, leaders weighing tons must be brought precisely into position down to the centimeter. The vibrating impacts, which drive sheet piles up to 22 m long into the ground, do not bother the HKS rotary actuator in the least.1The excavator shovel is swiveled according to theangle of the slope usingthe rotary actuator.2HKS actuator to swivel acrane cabin.3Attachments are posi-tioned, lifted, and loweredusing rotary actuators, forexample, the soil compac-tor here.Pure power delivered to exactly the right place123Our hydraulic actuators for implements for com-munity services make workers’ lives easier.The actuators ensure that the equipment is both mobile and can be positioned exactly. This makes it possible for machines to do work that previ-ously had to be done by hand. Thanks to their robustness and compactness, HKS rotary actua-tors can be used in especially long lasting and ergonomic designs.1Filling work can be per-formed more effectively andwill last longer thanks to theuse of rotary actuators 2The ability to position thewashing brushes exactlymakes it possible to cleanguide poles easily.3The brushes of the roadsweeping machine can getinto every corner withenough force thanks to thehydraulic rotary actuator.Versatile and robust in community service543Modern ships have a carefully arranged set of ballast tank systems which allow the ships to be trimmed for stability in any wind or weather, re-gardless of the load it is carrying.The electro-hydraulic HKS “power packs” are controlled by a computer on the bridge to open or close the armatures which empty and fill the ballast tanks.3Whole groups of rotary ac-tuators are used to operatethe armatures used to trimships.4Stern gangway which is be-ing extended with HKS ro-tary actuators.5Installation of a swimmingplatform on a luxury yacht.If required, the platform isextended with HKS rotaryactuators.4321Whoever wants to cut through solid rock needs tools that can take very heavy loads. With rotary actuators drill pipes for deep hole hammers can be reliably placed in any position and held at aprecise angle while the drill bores into the solid rock. The more difficult the local conditions are,the more important the mobility of our rotary actuators is for the heavy machinery.HKS rotary actuators hard at work underground 3With the HKS rotary actua-tors the drill pipes of thedeep hole hammer can beturned to any position.4Not only the heavy drill pipes are moved by the HKS rotary actuator, the actua-tor can also easily with-stand the impacts and vibration from the drilling without any difficulties.21Modern telescopic working platforms can reach nearly 90 meters into the air. Those who work at such heights must be sure that the platform is 100 % safe. HKS rotary actuators not only en-sure this safety, but also ensure that the plat-form can reach any position desired without jerky movement thanks to their smooth actuation and perfect damping.4The fire department makes no compromises when it comes to safety. This alsoapplies to their rescueequipment.Mobile and safe high in the air3With the strength of the HKS rotary actuators this concreteconveyor belt has enough range and mobility to move theready-mixed concrete to any position at the construction site.12People correctly expect extra reliability from rotary actuators that operate 2300 meters under sea level. After all, installation underwater is not veryeasy and long maintenance intervals are the norm.This is no problem for an HKS rotary actuator. Since neither water pressure nor saltwater can impair its function, it might even outlast the offshore platform.2HKS rotary actuator in a grabber for seabed explora-tion.1An example for reliability: At a depth of 2300 meters thisrotary actuator opens and closes the armature for a pipeline.Offshore, 2300 meters under sea level43HKS rotary actuators are used in the transporta-tion sector for everything from specialized air-field vehicles to the steering of forklifts. Electro-hydraulic actuators have been widely used in theDutch railway network for years, our rotary ac-tuators also help load shipping containers in ports.They are often used to open and fasten truck platform gates because of their low weight and favorable dimensions.4Reliable: Electro-hydraulic shunt device using an HKS rotary actuator for theDutch railway company.3The tow vehicle takes the nose wheel of the Airbus with theaid of two HKS rotary actuators so that it can move the air-plane into its parking position.1Our hydraulic rotary actuators are excellently suited to machines and equipment for agricul-ture and forestry. They are insensitive to mois-ture and dirt and need virtually no maintenance.Mechanical damage, as frequently occurs with hydraulic cylinders, is not possible for HKS rotary actuators.1Thanks to the high torque,even a small rotary actuatoris enough to move evenvery large tree trunks.Also for field, forest, and meadow2334522Economy and ecology go hand in hand with our hydraulic scrap shears and concrete pulverisers:their use greatly reduces working costs while si-multaneously reducing atmospheric pollutionwhich is created through incineration or the dust from demolition. With our know-how in hydrau-lic drive engineering, we can expand the field of use of such equipment and extend its lifespan.5HKS demolition shears can be mounted in any number of ways. This means that even taller buildings are no problem.3The HKS scrap shears caneasily move and load partsweighing tons with its hy-draulic actuator.4This HKS concrete pulveriser is exactly the right tool to remove steel reinforcement from con-crete.12324Our hydraulic rotary actuators normally work withan working pressure of 210 bar. That is why wecarefully seal them both inside and outside. Noth-ing gets in, nothing gets out. And since our ac-tuators do not emit any particles, in contrast to,for example, electric motors, they are suitablefor use in the food processing and pharmaceuti-cal industries.3We supply our rotary actua-tors in a stainless steelhousing if required.1Hygienic and suitable for use with food: HKS rotaryactuator to fill a cutter.2Also clean in the pharma-ceutical industry – to openand close the housing of acentrifuge.It could hardly be more hygienic and clean251232726In the chemical and petrochemical industries our hydraulic part-turn actuators are among the most reliable actuators for armatures. They hardly needany maintenance, work practically free of wear,and can be used even in areas endangered by explosions without problems. They withstand wind and weather and even aggressive atmo-sphere in the corrosion protected version.3Autonomous electro-hydraulic unit to power a throttle valve.1Thanks to their designhydraulic rotary actuatorscan also be used in areasendangered by explosions.2Compact and reliable: ball valve with hydraulic drive.HKS actuators: safely open and close34528Machine manufacturing is the classic domain ofHKS rotary actuators. Wherever work pieces areturned, lifted, swiveled, turned over, fed or re-moved, tools are changed, cages with parts aremoved, or devices moved precisely into position,we have the rotary actuator which will enableyou to exactly and precisely perform your task. 5Hot cast parts are movedprecisely into position fromthe climatised cabin of themanipulator.3HKS rotary actuator to feed casting moulds.4HKS rotary actuator in amachine for tire manufac-ture.293130Responsible interaction characterises the way our em-ployees work together, who come from 10 different nations. Proof of the active, positive internal co-opera-tion and the excellent working atmosphere lies in ourlow personnel fluctuation. In this way we can keep ourknow how and further develop it.The HKS Group companies are known for their appren-ticeships with opportunities for the future and are able to select their apprentices from a multitude of candi-dates. In this way our tomorrow’s qualified staff can learn within the company.However, the HKS Group hasn’t just gained a good repu-tation as an employer and trainer, its investments have now become an economic factor in the region.Through its innovative product strategy and the con-tinuous expansion of its range of activities, the HKS Group has been able to enjoy healthy and stable growth.This success is one reason why the company will con-tinue with its steady investment strategy.Technical University we carried out a research project involving the perfecting of performance by hydraulic actuators.That’s why HKS Dreh-Antriebe GmbH is the right partner when you require specialist knowledge for using rotary actuators to turn, lift and move... A further important aspect for the company is maintenance work for customers all over the world.In 2001 HKS’ new Business Division Recycling was formed. On the basis of many years’ experience in producing important components for scrap shears and concrete pulverisers these attachments are now completely constructed and assembled for the building and recycling industries. Furthermore we produce spare parts for this sector and carry out maintenance work.HKS Dreh-Antriebe GmbH & Co. KG in N eukirch,Lausitz, is the youngest member of the HKS Group of companies. It started from scratch in 1996 and the operations made a profit just three years after it had been founded. The Saxony-based company mainly produces larger rotary actuators. Owing to its location HKS Dreh-Antriebe GmbH & Co KG is the ideal contact for customers in Eastern Europe.5If you want to deliver preci-sion then you need perfectlymaintained equipment.6All new developments mustprove their quality in longterm tests which have beendeveloped in conjunctionwith Dortmund TechnicalUniversity.7HKS belongs to the compa-nies which from the begin-ning have had themselvescertified by NIS-Zert.The HKS Group is committed to the principle of partnership:working with each other and for the benefit of each other,treating customers and suppliers in the same way as we would treat each other within the company and in relation to the people in the region.The Group The three companies which form the HKS Group show how they have used their know-how to evolve from a manufacturer of simple rotary parts to a provider of complete attachments.The group consists of the following companies today: WalterHöhn GmbH, HKS Dreh-Antriebe GmbH and HKS Dreh-Antriebe GmbH & Co KG.Walter Höhn GmbH is the oldest of the three companies.Since it was founded in 1970 Walter Höhn GmbH producedrotary, milling and toothing parts in the best Germanmechanical engineering traditions. Even though the parts aremanufactured in the most modern CNC processing centres,the spirit of the founder’s work remains alive, which meantuncompromising dedication to precision in mechanicalproduction. Walter Höhn GmbH is responsible for the qualityof the components in the Group.HKS Dreh-Antriebe GmbH is responsible for engineeringwork, assembly and sales. The company has been connectedto Walter Höhn GmbH since 1985 through its ManagingDirector. HKS Dreh-Antriebe GmbH’s extensive know-how hasensured that our rotary actuators belong to the leadingproducts in their sector in Europe. In this area as well weconceive solutions for special tasks together with ourcustomers.
