1 Dotec Rotary-Action Rol-Handlers: (RH90) Features: Processes: Air Balancer 1. Dotec ErgoHandle operates Up & Down (proportional) speed- and tilting (90º) control. UP & DOWN The Slitting-Process concept (A) is one of the Dotec total Roll-Handling solutions. The (RDT) Trolley removes the complete batch of rolls from the shaft, the RH90 handler tilt the rolls for palletizing. This speeds-up the packaging process considerably and full use of the slitter/converter Speed is CG- unit 2 Tilting 90º 2. Center of Gravity achieved.

It pushes the Airchuck out of the Core Kg Lift & Tilt capacity (See graphics page) B pallet to the discharge positions. Lifting & Tilting can be done, centralized in the warehouse area. Smart roll-carts bring them to the packaging dept. High efficiency and little physical effort is the result.

3 A Dotec LiftAssist have very specific characteristics that has been based on ease of operation, speed of work and ergonomics in posture. The learning curve is very short. Work becomes a pleasure. Dotec The Friendly LiftAssist. Dotec ErgoHandle The central feature of the Dotec lift assist is the ergonomic handle, which is used to operate the lift assist. The handle can move freely up and down sliding through the hands, allowing the user to keep his eye on the load, while a mere finger touch determines both direction and speed. There is no need for bending and stretching (gymnastics) when lifting and storing in high places (or vice versa). Extra functions are activated by finger-tip touch of the levers at the sides. Without distraction or requiring special attention, likewise the steering wheel of a car. Not round but right-angled, since we move Up&Down. Smart logic Controls! (Fully pneumatic) The Dotec LiftAssist guides the process through the following stages: from empty to full moving putting down from full, back to empty (Release) (Automated sequence). Extra functions can be added and operated without using any buttons or switches. This makes operation foolproof. The logic controls responds automatically (proportional) to the user s movements and follows his own work speed. Compact valve-modules have been developed to achieve high speed reaction and avoid (speed) losses through long pneumatic tubing. They are in the centre of each logic control. The : (IR-Zimmerman) The air-balancer is the muscle of the system and makes the elastic vertical movement possible. The compressed air pressure is on both sides of the piston, which makes that the load is in balance. By letting in additional compressed air on one side of the piston and escaping air on the other side, the piston moves. The piston rod is connected to a ball-screw, which is connected to the reel. In this way the linear movement of the piston is turned into a turning movement of the reel, which means that the wire rope winds up and unwinds. Ball-scew In fact, the load is permanently supported (in balance) by an air cushion. The elastic effect is the result of the compressibility of air. This principle explains the difference between the operation of an Air-balancer and a Hoist. The logic control unit permanently measures the pressure in the piston chamber and uses this information to react. Once the lifting weight is In Balance only little extra effort (pressure) is needed to move the load UP & Down. This all creates the typical Dotec Dynamics! Cable Reel Piston & Cylinder Dotec ABC-System: The ABC-System is based on an Air- Balancer Cylinder instead of the Cable. It has the same Balance elastic movement. It s ment for higher loads up to 250KG. ZA- Logic Control: Activated by the Ergo-Handle, the basic ZA-logic control allow the compressed air to enter into the Balancer for the up/down-movement. The valves react proportional, which means that pressing the operating lever harder results in a quicker up & down movement. This makes operating the lift assist quick and dynamic, or quiet and accurate, whatever way of operating the process requires. This gives the operator the feeling that he (or she) decides what happens or should happen, which creates positive motivation and an acceleration of the overall process. Centre of gravity: An important feature in every Dotec system is the automated Centre Of Gravity adjustment. This unit secures the horizontal and vertical alignment under any condition. This means that an empty or loaded handler will always adjust itself into the correct position. Once adjusted for the application, it will align automatically.

4 A Jib cranes are perfect for short transfer applications. Aluminium rail for the boom is applied, resulting in an ergonomic, lightweight, easy to move boom. Jib cranes can be floor mounted on a column or ceiling mounted. Jib cranes provide up to 60 degrees of rotation and boom lengths to 5 m. An accurate and heavy-duty pivot bearing allow smooth and free 60º rotation. End-stops, with hydraulic damping, limit the radius, when necessary. A pneumatic parking brake secures a safe way of parking the machine, when not in use. Model C Low Headroom (max. 125 kg) can be applied in locations with low ceilings. Dotec Articulating Arms have very special hinge points. This design makes that the well-known disadvantages of the Banjo arm belong to history. In all directions the Dotec folding arm follows the movements of the operator in a direct line and will not straighten. To reach under e.g. a platform we developed the FlexArm (type D). With this arm the rolls until 80 kg can be taken from the pallet in upright position and placed on the machine shaft in horizontal position. Type E is also available in Super light but Super strong carbon-fiber. Weight reduction over the steel version > 68%. Dotec infrastructure: B E Hangerkit Low Headroom Suspension Trolley There are four solutions for the infrastructure: A: Aluminium rail system; B/C: 60 Rotating arm; D: FlexArm ; E: 700C folding (Banjo) arm, also available in super-light carbonfiber. The smooth operation of a lift assist highly depends on the correct infrastructure, needed for the horizontal movements. The infrastructure to be selected strongly depends on the area lay-out of the factory and the way of buffering the material that must be lifted. Our aluminium rail profiles are extruded from 606-T6 and anodized for a smooth, clean, corrosive-free surface. The enclosed rail design reduces the accumulation of dirt and grime on the internal running surfaces, thus reducing rolling effort. The special rail profile, the unique way of suspending and the advanced trolley design guarantee a rolling resistance of 1% of the load to be moved. C D
