Cat introduces Ultra High Demolition machine

Caterpillar’s new 352 UHD Ultra High Demolition excavator is designed to handle difficult demolition of tall structures.

It uses 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 two people with no special tool required, Cat says.

The 352 UHD features a variable-gauge undercarriage (hydraulically activated), as well as the Cat Active Stability Monitoring system, which warns when approaching stability limits.

In the UHD configuration, the 352 UHD provides 28 metres of vertical height to the work tool attachment pin, and 15.8 metres of horizontal reach, when working with a 3,700 kg tool. These specifications allow the 352 UHD to demolish structures eight or nine stories high. Undercarriage gauge is 4.0 metres when working, 3.0 metres for transport.

In retrofit straight boom configuration, the 352 UHD uses a 9.1-metre retrofit boom with a choice of 2.9-metre or 3.35-metre retrofit stick. Equipped with the longer stick and a 3m3 bucket, the 352 UHD has a digging depth of 6. 670 metres and a maximum reach at ground level of 11.88 metres.

The 352 models use the Cat C13 engine, rated at 304 kW, meeting the EU Stage V emissions standard. The C13 also is capable of operating on biodiesel up to B20. Three power modes in the machines allow the operator to match machine performance to the task at hand, and a hydraulic reversing fan cools the engine on demand to help reduce fuel consumption.

When using the retrofit boom, the machine can use the Cat GRADE with 2D grade control system, swing e-fencing and the Cat Payload on-board weighing system. The Payload system can be used with VisionLink (online telematics interface) to remotely manage production targets via the machine’s Product Link telematics system.

Inside the cab, each joystick button can be programmed, including power mode, response, and pattern, and these settings can be recalled using appropriate operator identification. An automatic hydraulic oil warmup feature quickly brings the system to operating temperature and helps prolong component life. The 10-inch (254mm) touchscreen monitor includes operating and maintenance tutorials.
