1 Kalmar Log Stackers Boosting the productivity

2 Wood handling performance brought to a higher level Kalmar Log Stackers have been developed with the highest possible performance in mind. We have carefully analyzed the different loading situations, work cycles and applications. The machine performance is a combination of power and speed in both hydraulic functions and transportation. Due to the large grapples available and the excellent stability of the Kalmar reach machine concept, the Log Stackers are very efficient for transporting logs at wood yards or even on longer hauls. As a result of their high stacking capability, Log Stackers can utilize your storage space very efficiently and build stacks of up to 9 meters high. The grapple is the tool The most important tool for high performance is the grapple. Kalmar has developed a unique range of grapples for every possible application. The new parabolic grapple form fills up efficiently thus speeding up the gripping procedure, but also maximizing the load in the grapple. In most cases it is possible to pick up the whole bundle from the truck or rail car at one time; this is the key to efficiency. The power Another key element for efficiency is the power. The low emission diesel engines in the range of 250 to 300kW supply energy for the ZF Ergopower transmission; the tractive effort is not interrupted during shifting. Gear shifting is automatic with 4 speeds forward and 3 speeds in reverse. RTD1623 2

3 The Economy The load sensing hydraulic pumps take only the power needed for the actual hydraulic movements, making it possible to drive the machine and operate the hydraulics simultaneously without loss of energy. There are multiple pumps and circuits in the system to facilitate simultaneous independent hydraulic movements. The result is speedy and efficient operation, excellent fuel economy and low operation temperature in the hydraulics, because all energy losses have been minimized. The extra wide low profile front tyres on the RTD1623 last more than twice as long as the tyres on its preceding model. There are real saving on running costs! Control Important element for efficient operation is how the various functions of the machine can be controlled. The cabin offers a spacious and ergonomic environment for the operator with the comfort that is essential for maintaining the operator s mental agility during the long and busy working shift. All the controls are within easy reach and intuitive and all the functions are computer controlled. Through a graphical user interface with colour display it is possible to monitor all machine functions and even set certain control parameters and features to fit individual needs. The colour display replaces all gauges and pointers and automatically gives an alarm with a message if the operator s attention is needed. The climate inside the cabin is controlled by the automatic electronic climate control ECC. The operator just sets the desired temperature and the system takes care of the rest. 3 Magnisim enibh exero core faciduisl eugue molutpating RTD3026 exerit utpat, quisism odolut vulla feumsan vulluptatue et nullum dit praestion ulla.

4 The cabin is equipped with optional equipment. The Platforms Kalmar Log Stackers are built on two product platforms: The RTD1623 chassis and the RTD3026 chassis. By combining these platforms with the available grapples, it is possible to cover a load range from 14 to 30 tonnes and handling of cut to length logs from 2 meters up to 6 meters or even longer. The two chassis alternatives actually have very much in common: The process machines Most mills operate 24/7, meaning that wood yards function every weekday for 24 hours. In practise this means that the Log Stackers must be operational at all times and constantly feed the mill with logs or unload incoming wood. This requirement makes the Log Stackers the hardest working Kalmar products and 6000 hours of operation annually have often been exceeded! Identical cabins and controls Common electrics Common control system and hydraulics In short, only load and capacity related components differ. This principle of engineering offers several advantages for the owner/user: Many spare parts are common Easier for service and diagnostics Easier for the operator to switch from one model to the other at the same wood yard. 4

5 Uptime and service Grapple options The 24/7 requirement sets very high expectations for Log Stacker uptime and availability. In the worst case, the whole mill will close if the Log Stackers are down and standing. Parts availability, service and product support for this kind of operation is crucial. Kalmar can offer its customers full service contracts to keep the machines serviced and operational. We have suitable grapples for every operation. And if not, we will produce one for you! The range of grapples for the RTD1623 varies from 4.0m² to 6.5m² and the grapples for the RTD3026 from 7.0m² to 8.5m². The most recent development is the parabolic form, but the traditional V- and U-shapes are also available. The appropriate grapple size depends on the log length and bundle size. Manoueuvrability Service access There is often a lack of space at the wood yard and narrow aisles. The turning radius of Kalmar Log Stackers is extremely small; these big machines can turn even where there is little space. Component layout and access are well designed. The hydraulic functions are on the left hand side and the electrics on the right. The cabin tilts to the left (by means of an electrically operated pump) allowing good access to the power line components and hydraulic pumps from the top. All daily checks are concentrated in one place next to the entrance to cabin. 5
