The Cat 333 hydraulic excavator improves on the features of the Cat 330 model with a larger bucket and 15% more digging force. The machine stability and durability have been increased due to its wide track gauge and reinforced structures.
Powered by a 194-kW (260-hp) Cat 7.1 engine, the Cat 333 excavator features two engine operating modes – Power and Smart – to match the machine to jobsite conditions. The Power mode delivers maximum power to meet the most demanding tasks. The 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 excavator offers auxiliary hydraulic options to power a wide range of Cat attachments including buckets, grapples, hydraulic hammers, pulverisers, sheers, vibratory plate compactors and multi-processors. Its high-ambient capability of 50˚C, cold-starting at temperatures as low as –18˚C and ability to work at high-altitudes up to 4500m above sea level allows the machine to work in a wide range of climates.
Prolonging the life of machine components, auto hydraulic warmup gets the Cat 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.
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.
The new cab design of the Cat 333 provides increased protection against operator fatigue and external stresses. A push-to-start button or Operator ID function offers 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.
Large cab windows, along with a lower front, right, and rear machine profile, offer high visibility of the work area without straining. The excavator’s 203-mm, 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 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 labour 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 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. The Cat Product Link remote monitoring system 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.
