HKS Dreh-Antriebe GmbH

With the new hydraulic XtraTilt rotary actuator HKS offers cylinder-free tilt technology for construction technology. This rugged technology outperforms cylinder-based systems because it is far more compact, more reliable and offers a greater tilt angle.

Being the only modular system in its class, it grows with the task in hand: starting from a pure rotary actuator for shovel tilt movements (XtraTilt) and a rotation unit (RotoBox) through to the combined tilt and rotation solution with quick release and permanent shaft connection (TiltRotator), the construction technology equipment level can be tailored to meet individual needs. This power drive technology is therefore also ideally suited for upgrading. This innovative system is compatible with all conventional quick-release systems for construction machinery of up to 100 tonnes.

Tried-and-tested technology for new applications
The fully developed coarse thread technology has been tried and tested for the past ten years in excavator bucket positioning applications. The latest generation of this power actuator is now called XtraTilt. Building construction, civil engineering and road building companies as well as gardening and landscaping businesses are among the users of this new technology.
The HKS XtraTilt increases the efficiency and productivity of the machinery it is fitted to. For instance, fitting the power actuator to the excavator bucket makes it far more manoeuvrable and increases its tilt angle about by forty percent versus conventional solutions.

In addition, the cylinder-free design is about 50% thinner than cylinder-based technologies. This means that the XtraTilt can also swivel narrow backhoe buckets so that you can work more conveniently and precisely.

Powerful and reliable
The unique modular system provides a perfect solution for every task: the HKS XtraTilt module is an ideal solution for purely tilt movements of up to 180°. It is composed of merely four components and can therefore easily be maintained - even in your own facilities. The holding torques extend up to 165,000 Nm.

Besides this, the KS RotoBox permits continuous left/right rotation. It can turn at a speed of up to eight rotations per minute. With an oil throughput of up to 390 l/min, it has the largest oil rotary oil joint currently on offer. This ensures consistent and reliable high performance. A tough worm gear unit functions precisely and is self-locking. The RotoBox is suitable for all excavator classes up to 45 tonnes.

Simultaneous swivelling with 2 x 55° and continuous left/right rotation allow the HKS TiltRotator to be a complete solution. This innovative technology attains holding torques of up to 100,000 Nm. The excavator itself can therefore remain longer in the same position, which also has a positive impact on fuel consumption. The HKS TiltRotator functions around forty percent faster and more efficiently than cylinder-based tilting buckets. It is suitable for applications in excavator classes of up to 47 tonnes.

Better without cylinders
This innovative system is compatible with all conventional quick-release systems and due to the wide variety of models it is also compatible with all construction machinery up to 100 tonnes. In addition, being a sealed system, the cylinder-free technology has a high degree of wear resistance and functions very precisely. The units are controlled by the excavator operator using intuitive movement buttons. Further information and images can be found at www.better-without cylinders.com.

Under the familiar slogan, "better without cylinders" HKS offers cylinder-free tilt technology for construction technology in the shape of its XtraTilt hydraulic rotary actuator.

Offering short delivery times, XtraTilt is also a durable, robust, high-quality sealed system that does not require any lubrication points due to its self-lubrication system. Thanks to the special deflectors on both sides, the HKS XtraTilt series prevent dirt from entering the housing as soon as they leave the factory, which means that they are easy to maintain, thus considerably reducing maintenance costs. No readjustment necessary even after many hours of operation. This means that the XtraTilt makes daily lubrication and maintenance routines entirely redundant. In addition, the actuator centring mechanisms on both sides guarantee more efficient load bearing and torque transmission characteristics.

The HKS XtraTilt increases the efficiency and productivity of the machinery it is fitted to.
The tilt angle is far greater than that offered by conventional ditch digging buckets with cylinders and therefore means that the attachments fitted are considerably more agile. In addition, the HKS design permits any attachment to be tilted, thus allowing you to work more conveniently and precisely. The HKS XtraTilt series gives users a choice of three standard tilt angles. In order to reduce costs, weight and installation height, HKS also offers 2 x 50° and 2 x 70° versions alongside the 2 x 90° model. The XtraTilt is composed of four wear-resistant components. There are 44 versions with 17 installation sizes, which are available with carrier device weights of up to 100 tonnes and holding torques of up to 165,000 Nm.

Using the HKS-XtraTilt you can tackle the most diverse tasks, for instance: Embankment, trench digging, metering, drainage or roadbuilding works. At the same time, the stable platform it provides allows you to work on inclined planes (hillsides) while holding and positioning the attached implements precisely. In general, it is compatible with quick release systems, carrier implements and tools from any manufacturer, which means that upgrading with HKS construction technology is as straightforward as possible.
