The project

综合调配

在瑞典的Sundsvall镇,SCA Paper经营着一家拥有四台机器的工厂,生产报纸和杂志印刷用纸。向两个熔炉供应燃料,以产生生产过程中所需的蒸汽。这项任务由一台自动化的Demag过程起重机执行。必威体育

The double-girder overhead travelling crane has a load capacity of 12 t and travels on a runway at a height of approximately 30 m. It clears shredded wood chips from two tipping positions and first heaps them in the storage area. Using a motor-powered multi-jaw grab, which has a capacity of up to 8 m3thanks to its enclosed design, the crane also picks up deliveries of slurry and distributes it over the entire storage area. The calorific value is homogenised by blending these two materials.

全天候运行

起重机昼夜不停地工作,在零下30度的温度下也能平稳运行。因此,整个螃蟹都配有加热、绝缘和隔音的外壳,保护所有部件免受天气影响。电气设备额外加热。起重机装置的电气部件安装在起重机桥架上的绝缘和加热容器中。八个用于长行程运动的电机和四个用于横向行驶的电机确保起重机准确定位,即使在强风条件下也是如此。只有在风力为10时,起重机才会关闭并机械锁定。

声音保护让邻居高兴

由于对岸有居民区,也必须采取降噪措施。整套措施使噪音水平大大降低到80分贝以下。除了隔音蟹壳,这还包括对开放绞车单位和低噪音抓斗减速。
