The Caterpillar 385D and Caterpillar 390F excavators are heavy - duty machines, weighing between 80 and 95 tons. These excavators are built for tough jobs. During the design, we simulate extreme working conditions thoroughly to guarantee structural integrity. Premium materials like T1 and heat - treated steel are used at high - wear points and stress areas. The bucket capacity is 2.09, making it efficient for various excavation tasks.
To use these Caterpillar excavators, first, make sure the machine is on a stable surface. Start the engine following the normal procedure in the operator's cab. You can control the boom, arm, and bucket using the joysticks to perform digging, loading, and other tasks. When operating, always keep an eye on the surroundings to avoid hitting obstacles. As for maintenance, check the oil, coolant, and hydraulic fluid levels regularly. Inspect the tracks for wear and tear and tighten any loose bolts. Also, clean the air filters to ensure the engine runs smoothly. After long - term use, have a professional technician perform a comprehensive inspection and service.
