任务

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%。

在瑞士泽马特的高山地区，LTR1060是碎石路的主人，弯道很紧，坡度高达40%。就这样，利勃海尔的伸缩式履带起重机再次考验了它的越野能力。

即使弯道过弯也能防止翻倒

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°。

窄履带的操纵性

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。

在巨大负担下检查变速箱温度

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

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。”。
