Cat 333 hydraulic excavator ... increased productivity.
New Cat offers more digging force, durability
01 March 2022
Built for tough applications, Caterpillar says its new Cat 333 hydraulic excavator offers an increased bucket size, up to 10 per cent more bucket force and up to 15 per cent more stick force than the Cat 330 to maximise performance.
In addition to its 15 per cent 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, according to a spokesman for the leading construction equipment manufacturer.
“The new 333 excavator delivers reliable operation and increased productivity when working in challenging applications,” he says. “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.”
Powered by the 194-kW (260-hp) Cat 7.1 engine, the 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, he says, while smart mode automatically matches engine and hydraulic power to digging conditions, offering up to 10 per cent 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, pulverisers, sheers, vibratory plate compactors and multi-processors. Its high-ambient capability of 50 deg C, cold-starting at temperatures as low as -18 deg C and ability to work at high-altitudes reaching to 4,500 m above sea level allows the flexible machine to work in a wide range of climates,” the spokesman points out.
Prolonging the life of machine components, auto hydraulic warm-up gets the 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 pre-cleaner 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, he adds.
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 protects the operator from the fatigue, stresses, sounds and temperatures of the rugged applications where the 333 excavator typically works, according to the spokesman. A push-to-start button or Operator ID function offers simple, keyless engine ignition. Using the unique Operator ID passcode, operators can programme 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 spokesman says. The excavator’s 8-inch high-resolution touchscreen monitor offers quick navigation through machine controls and provides easy access to the digital operator’s manual.
