For Release in Japan: February 2020

The Cat® 352 UHD Ultra High Demolition excavator 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. The UHD front can be switched for a straight or bent (retrofit) boom position for lower-level demolition and earthmoving applications. This switch typically is done in about 15 minutes with 2 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 91.8 feet (28 m) of vertical height to the work tool attachment pin, and 51 feet (15.8 m) of horizontal reach, when working with an 8,150-pound (3.7 t) tool. These ample specifications allow the 352 UHD to demolish structures eight or nine stories high fast, with precision and control thanks to the electro-hydraulic control system. Undercarriage gauge is 13 feet (4 000 mm) for optimum stability when working, and 10 feet (3 000 mm) for transport with 24 inch (600 mm) track shoes.

In retrofit straight boom configuration, the 352 UHD uses a 29.75-foot (9.1-m) retrofit boom with a choice of 9.4-foot (2.9-m) or 11-foot 3.35-retrofit stick. Equipped with the longer stick and a 4.0-cubic yard (3.08 m3) bucket, the 352 UHD has a digging depth of 21.8 feet (6 670 mm) and a maximum reach at ground level of 38.92 feet (11 880 mm).

The 352 models use the Cat C13 engine, rated at 408 horsepower (304 kW), and meeting EU Stage V/U.S. EPA Tier 4 Final emissions standards. Three power modes in the machines allow the operator to match machine performance to the task at hand, and a new high efficiency, hydraulic, reversing fan cools the engine on demand to help reduce fuel consumption.
