Working with up to a 6,000kg attachment weight, the new 352 straight boom features standard Cat technologies for increased versatility, precision and efficiency in both demolition and excavating applications. The excavator’s new optional 11.35t removable counterweight design is said to increase transportation efficiency and lowers transportation costs. The mechanical variable gauge undercarriage has a 2,990mm transportation width when needed and extends 500mm in working mode. Its new hydraulic fan features standard automatic reverse to keep the cores free from debris and reduce maintenance time.

Simple, safe and reliable operation

Designed for demolition, the 352 straight boom features reinforced booms, sticks and frame, to increase machine durability. Standard Falling Object Guards (FOGS) protect the roof and front reinforced P5A laminated windows from falling debris during demolition while helping to maintain visibility on the jobsite. Sloped to prevent mud and debris accumulation, the track frame design helps to reduce track damage, while sealed track pins and bushings reduce travel noise and help to increase undercarriage life. Full track guiding guard is also a standard feature.

The ’Operator ID’ function offers push button engine starting and programmable joystick functions that are remembered when the operator enters the unique ID. Standard ‘Cat Stick Steer’ simplifies excavator movements with single hand and push button operation of travel and turning. Offering automatic power increase when needed, standard ‘Auto Dig Boost’ aims to deliver better bucket penetration, shorter cycle times and greater payloads. ‘Auto Heavy Lift’ offers more lifting power when needed for as long as needed. ‘Cat Lift Assist’ makes the operator aware that the load is within the excavator’s safe working range to avoid tipping.

Standard Cat technologies to elevate operating efficiency include ‘Cat Grade’ with a 2D touchscreen monitor. When excavating, ‘Cat Payload’ offers real time, onboard weight estimates to help achieve precise load targets and can be combined with ‘VisionLink’ for remote management of production targets. ‘Cat Product Link’ provides critical machine operating data. To easily detect objects and personnel around the operator in a single view, the 352 straight boom comes standard with rear view and right hand sideview cameras, which can be upgraded to provide 360o visibility.

The 352 straight boom features an electrohydraulic system and is powered by the 330kW Cat C13B engine. Standard quick coupler, medium and high pressure circuits are designed to increase operating versatility for 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.

Easy maintenance

The new Cat 352 straight boom excavator provides remote diagnostics and updating capabilities. ‘Remote Troubleshoot’ allows the dealer to diagnose fault codes and machine issues remotely without interrupting the production cycle. ‘Remote Flash’ allows software updates to be installed at a time convenient for the customer. Grouped together for simplified maintenance, all fuel filters now feature an extended, synchronised 1,000h change interval. Combined, these features aim to help to lower long term owning and operating costs.

Long life fuel, oil and air filters reduce maintenance, and hydraulic oil checks and fuel system purging of water are done from ground level. The operator can easily track filter life and maintenance intervals from inside the cab. The updated hydraulic system improves filtration performance, while anti-drain valves help keep the hydraulic oil clean when replacing the filter.
