New Cat® 333 excavator offers more digging force, durability and low cost-per-hour operation

For Release in Africa, China, Middle East, Indonesia, Southeast Asia, Turkey: February 2022
Release Number: 21PR22

Built for tough applications, the new Cat^® 333 Hydraulic Excavator offers an increased bucket size, up to 10% more bucket force and up to 15% more stick force than the Cat 330 to maximize performance. In addition to its 15% more digging force, the 333 excavator boasts wide track gauge and reinforced structures for increased stability and durability. Extended maintenance intervals combine with a fuel-efficient hydraulic system and two engine power mode options to lower cost-per-hour operation.

The new 333 excavator delivers reliable operation and increased productivity when working in challenging applications. Reinforced linkage, sticks and booms help to deliver higher digging forces when excavating tough materials. Further increasing durability, the frame of the machine is reinforced to ensure a long service life while performing at a higher capacity.

Reliable, high performance

Powered by the 194-kW (260-hp) Cat 7.1 engine, the new 333 excavator features two engine operating modes – Power and Smart – to match the machine to jobsite conditions. Power mode delivers maximum power to meet the most demanding tasks. Smart mode automatically matches engine and hydraulic power to digging conditions, offering up to 10% fuel savings.

Combined with higher digging forces, the excavator’s large bucket capacity efficiently moves more material in fewer passes to improve productivity. The versatile 333 excavator offers auxiliary hydraulic options to power a wide range of Cat attachments, including buckets, grapples, hydraulic hammers, pulverizers, sheers, vibratory plate compactors and multi-processors. Its high-ambient capability of 50˚ C (122 F), cold-starting at temperatures as low as -18˚ C (0˚ F) and ability to work at high-altitudes reaching to 4500 m (14,760 ft) above sea level allows the flexible machine to work in a wide range of climates.

Prolonging the life of machine components, auto hydraulic warmup gets the new 333 excavator to work faster when working in cold temperatures. Two levels of fuel filtration offer enhanced engine protection from diesel contaminants. A double element air intake filter with integrated precleaner features high dust capacity. Lowering fuel consumption, a high-efficiency hydraulic fan cools the engine on demand and offers an optional reverse function to keep the cores clean.

Featuring a sloped design, the track frame prevents mud and debris accumulation to reduce the risk of track damage. Grease sealed between track pins and bushings reduces travel noise and prevents debris infiltration to increase undercarriage life.

Simple to operate, easy to maintain

The new cab design protects the operator from the fatigue, stresses, sounds and temperatures of the rugged applications where the 333 Excavator typically works. A push-to-start button or Operator ID function offers simple, keyless engine ignition. Using the unique Operator ID passcode, operators can program preferred power mode and joystick settings, and the excavator automatically recalls individual preferences based on the passcode.

With all controls ergonomically positioned in front of the operator, the layout helps to reduce fatigue and straining movements. Large cab windows, along with a lower front, right, and rear machine profile, offer outstanding visibility of the work area without straining. The excavator’s 203-mm (8-in) high-resolution touchscreen monitor offers quick navigation through machine controls and provides easy access to the digital operator’s manual. At the touch of a button, operators can switch to the optional Cat Stick Steer for simple one-hand operation of travel and turning.

Offering a 50% longer life than previous filter designs, the hydraulic oil filter features improved filtration performance, anti-drain valves and a 3,000-hour replacement interval. Long-life fuel, oil, and air filters combine with synchronized 1,000-hour oil and fuel filter service intervals to substantially reduce downtime. The extended intervals eliminate the labor cost for nine oil and fuel filter changes and parts cost for 27 oil and fuel filters over 10,000 machine operating hours compared to many competitive models in its class. Operators can easily track filter life and maintenance intervals through the touchscreen monitor.

Daily maintenance checks are completed from ground level to minimize the need for accessing the upper platform. Consolidated filter locations help to expedite machine servicing. Product Link^TM automatically collects vital machine operating information like location, hours, fuel usage, idle time, maintenance alerts, diagnostic codes, and machine health, which can be viewed online through web and mobile applications.
