Formal launch for Cat 352 UHD
21 January 2021
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 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.
