利勃海尔LTR 1060履带起重机在高山地区的应用

在欧洲第二高山铁路瑞士戈纳格拉特铁路(Swiss Gornergrat railway)的隧道工程中,LTR1060伸缩式履带起重机的技术进行了考验。在利勃海尔专家的技术支持下,它在一条布满砾石、弯道和巨大斜坡的路线上运行。在此过程中,伸缩式履带起重机再次展示了其在极端条件下的越野能力。

由于窄桥承载能力小,履带式起重机不得不将低装载机卸下。然后独自行进。

位于沃利斯的起重机运营商克劳森公司的利伯海尔LTR 1060伸缩起重机已经在过去的几次高山地形中证明了自己的能力。但在瑞士瓦莱州的采尔马特使用时,克兰和他的团队发现他们面临着一系列的挑战。

起重机操作员Geri Clausen的任务是:扩建瑞士Gornergrat铁路的一条隧道,包括一条滑雪道。这个项目的困难主要在于接近海拔2020米的场地。这条路穿过一条920米长的碎石路,弯道最紧,坡度高达40%。

行动中的挑战和解决方案

LTR 1060面对着一条长达920米的蜿蜒小路,到工作现场的高度差为180米。

利勃海尔设计部总经理汉斯·迪特尔·威利姆和他的团队提前计算了机器的整体重心,以确保在转弯和爬坡时的翻车安全性和操纵性。结果:LTR1060可以在没有压舱物的情况下行驶,总重量为38吨,动臂角度为20°。

由于路径狭窄,LTR1060只有一条狭窄的轨道可以在蛇形轨道上导航。随之而来的挑战:履带长度和履带宽度之间的不利比率严重限制了转向能力。

在紧弯管上,LTR 1060必须在精确定义的位置转弯。利勃海尔建议把方木下的内曲线履带链作为支点。此外,选择履带式底盘的行驶方向,使链传动位于后部。这样可以确保履带链绷紧。

尽管负载很重,齿轮箱和滚柱的温度仍远低于最大允许值。

这条又长又陡的路使变速箱承受了很大的压力。挑战是保持齿轮箱和滚筒的温度低于最大允许值。

利勃海尔设计部总经理汉斯·迪特尔·威利姆(Hans Dieter Willim)用热成像相机现场检查了关键部件的温度曲线。在与德国比贝拉赫变速箱制造商利勃海尔协商后,变速箱油位也提前小幅降低。这样可以防止因机油旋转而造成的飞溅损失。

结论

目标:在马特宏峰的背景下,LTR1060工作在一个山区铁路隧道的屋顶上。

在成功完成高空作业后,起重机操作员Geri Clausen总结道:“我们有很多场地,这种高度可操作的起重机非常理想。”。
