卡特彼勒已正式推出其352 UHD超高拆除挖掘机，据称该挖掘机可使用一系列Cat拆除附件来处理高层建筑的拆除，包括多处理器、抓斗、剪切机和带有液压臂的液压锤。

该挖掘机于2020年开发，是“世界拆除奖（World Demolition Awards)”的“制造商创新工厂和设备”类别的获奖产品。

机器的前面板可切换为直臂或弯曲臂（改装）位置，以用于较低的拆除和土方工程。根称，这项工作通常需要两个人大约15分钟，而无需任何特殊工具。 352 UHD具有可变规格的底盘系统（液压启动），以及Cat主动稳定性监测系统，该系统可在安全工作范围内通知操作员作业工具位置，并在接近稳定极限时发出警告。

当使用3.7 t（8,500 lb）工具工作时，作业机具固定销具有28 m（91 ft）的垂直高度，并具有15.8 m（51 ft）的水平范围。

卡特彼勒还推出了340 UHD机型，它具有延长的液压油间隔，更少的燃油消耗，并符合欧洲Stage V以及美国和日本的排放标准。

Formal launch for Cat 352 UHD

By Steve Ducker

Caterpillar has officially launched its 352 UHD Ultra High Demolition excavator, which it says is designed to handle difficult demolition of tall structures using a range of Cat demolition attachments, including multi-processors, grapples, shears and hydraulic hammers with the retrofit boom.

Developed in 2020, the excavator was the winning entry in the Manufacturers’ Innovation Plant and Equipment category of the World Demolition Awards.

The 352 UHD provides 28 m (91 ft) of vertical height to the work tool attachment pin

The UHD front can be switched for a straight or bent (retrofit) boom position for lower-level demolition and earthmoving applications. According to Cat, this typically takes about 15 minutes with two people with no special tool required. The 352 UHD features a variable-gauge undercarriage (hydraulically activated), as well as the Cat Active Stability Monitoring system, which continuously informs the operator of work tool position within a safe working range and warns when approaching stability limits.

In the UHD configuration, the 352 UHD provides 28 m (91 ft) of vertical height to the work tool attachment pin, and 15.8 m (51 ft) of horizontal reach, when working with a 3.7 t (8,500 lb) tool.

Also on show was the 340 UHD, which features extended hydraulic oil intervals, reduced fuel consumption, and meets European Stage V, US and Japanese standards.
