Moving timber bunks hydraulically 22.08.2018 Product news Alucar has designed solutions for moving timber bunks hydraulically for two different purposes: simply moving the empty bunks when the length of timber changes and moving a loaded, bundled load on the bunks. “When all the bunk stakes provide maximum support for the bundle, the bunks’ working life is considerably longer ” Julius Närvä “We have long been making mechanisms for moving bunks for individual customers, but due to increased demand, we now offer ready-made products for both bunk moving purposes,” says Julius Närvä from Alucar. The moving mechanism will lengthen the bunks’ working life Moving empty bunks hydraulically makes the driver’s work easier when the length of timber varies. This means that nudging the bunk frame with the crane is history and the timber bunks are always easily moved to the right place. “The moving mechanism will lengthen the bunks’ operating life and keep them undamaged and smart. When the bunks don’t need to be moved manually, their surface finish lasts longer and you no longer have to worry about the deep dents made by the grab, which is usually where damage to timber bunks originates. When all the bunk stakes provide maximum support for the bundle, the bunks’ working life is considerably longer,” Närvä explains. Alucar also offers a solution for moving entire bundled loads The moving of timber bunks can be controlled either with a separate hydraulic drive or one of the crane’s drives. In addition to moving timber bunks, Alucar also offers a solution for moving entire bundled loads, which is necessary especially with certain types of chassis due to the need to optimise the centre of gravity. For example, when the crane is left on the levike after loading, the bundle’s centre of gravity has to be moved back so that the weight of the front axle isn’t exceeded. The centre of gravity can also be changed to increase the grip of the drive wheels or weight can be moved forward to increase grip when turning. “Moving the bundles can also be utilised when unloading. When loading, the bundles can be loaded so that they are right next to each other and partly even interlocked. At the unloading site, the bunks supporting the rear bundle are moved towards the back of the truck, which will give you the unloading space you need. This means that a full-size truck can transport two five-metre-long bundles at the same time and the load can be removed with any unloader type used by factories,” Närvä explains.
