New Cat 335 excavator

With its compact radius design, the Cat 335 Next Gen Hydraulic Excavator brings premium performance and the highest level of standard factory technology to the 35-ton excavator class. Caterpillar reckons its new 335 boasts the tightest tail swing radius in the industry, making it ideal for working on space-restricted jobsites, such as road projects with lane closures, and excavating next to buildings.

The 273hp Cat C7.1 engine powering the 335 meets the most stringent emissions standards with a no-maintenance aftertreatment system. Three selectable operating modes – Power, Smart and Eco – with one-touch low idle help to reduce fuel consumption by up to 10%. The standard engine configuration offers high ambient temperature operating capacity of 52C (126F), cold start capability of -18C (0F) and 15,090ft (4600m) altitude capability.

The new 335 features increased stick and bucket cylinder sizes to provide 15% greater digging forces to power through hard ground and asphalt. Hydraulic power is increased by 20% to boost productivity. Yet fuel consumption remains similar to the previous model. Selecting the engine Smart mode saves even more fuel by automatically matching the engine speed and hydraulic power demand, based on how hard the operator is digging. The use of Smart mode typically reduces fuel consumption by 10% with no impact on productivity.

The 335 also features optimised weight and dimensions to meet the most common transportation limits. For example, the track gauge is wider to improve side stability, yet total machine weight is under 36,200kg, with or without a blade. Auxiliary hydraulic options for a wide range of Cat attachments increase versatility. Material penetration and improved cycle times are achieved through Advansys bucket tips, which are quickly changed without a hammer or special tool to improve safety and uptime. A new, wider blade is available to cover the width of wide track shoes. Key stats for the new Cat 335 include a maximum digging depth of 6.99m, a maximum reach at ground level of 10.6m, and a maximum loading height of 7.96m (all with a 6.15m boom and 3.2m stick).

The usual suite of productivity-enhancing Cat technologies applies here, which the manufacturer says boosts machine efficiency by up to 45% compared to manual operation. The Cat 335 Next Gen excavator gives customers a choice between reengineered Deluxe and Premium cab designs featuring vibration-reducing viscous mounts, adjustable operator seats and automatic climate control to increase operator comfort. Ergonomically positioned to reduce fatigue, customisable joysticks allow pattern and response settings to be saved to operator preference. Meanwhile, the tilt-up console eases operator entry and exit.

Operators have excellent visibility into the trench to either side and to the rear of the excavator thanks to a flat engine hood design, smaller cab pillars and large panoramic windows. Standard rear-view and right-view cameras further enhance visibility and safety and can be upgraded to offer 360-degree visibility. All daily service points are accessed from ground level to increase efficiency and improve safety. The new service platform toward the front of the machine features anti-skid punch plate to prevent slipping and provides easy and safe access to the upper service platform.
