THE new Cat 352 Straight Boom excavator has been designed specifically for low-level demolition work, bridges and industrial infrastructures.
The machine’s stick/boom configuration is described by the manufacturer as delivering a higher vertical reach up to 12.85m, 36% more stick pin height compared to the standard 352 Reach configuration.
The new optional 11.35-tonne removable counterweight design is said to increase transportation efficiency, while the mechanical variable gauge undercarriage has a 2.990mm transportation width when needed and extends 500mm in working mode. A new hydraulic fan features standard automatic reverse to keep the cores free from debris.
The 352 Straight Boom features reinforced booms, sticks and frame. Standard Falling Object Guards (FOGS) protect the roof and front reinforced P5A laminated windows from falling debris during demolition, while helping to maintain visibility.
Sloped to prevent mud and debris accumulation, Cat added that the track frame design helps reduce track damage, while sealed track pins and bushings reduce travel noise and help to increase undercarriage life.
An Operator ID function offers push-button engine starting and programmable joystick functions that are remembered when the operator enters their unique ID.
Standard auto dig boost is designed to deliver better bucket penetration, shorter cycle times and greater payloads. Auto heavy lift offers more lifting power when needed. Cat Lift Assist makes the operator aware the load is within the excavator’s safe working range to avoid tipping.
To help detect objects and personnel around the operator in a single view, the 352 Straight Boom comes with standard rear view and right-hand-sideview cameras, which can be upgraded to provide 360-degree visibility. Smaller cab pillars, larger windows, standard radial roof wiper and washer seek to improve visibility.
The model features an electrohydraulic system and is powered by a 330kW Cat C13B engine. Standard quick coupler, medium and high-pressure circuits increase versatility for using a variety of Cat demolition attachments. Three engine power modes – Smart, Power and Eco – help to match engine and hydraulic power to the task at hand.
All fuel filters feature an extended 1,000-hour change interval.
