Key Features:

Proven Power Unit The excavator is equipped with the Cat C3.6 four-cylinder turbo diesel engine, delivering 71.2 kW (95.5 HP) net power at 2200 rpm. This reliable factory engine provides strong low-speed torque, stable output under continuous medium loads and good fuel economy for long-hour site operations. Optimized power matching design reduces fuel consumption, and it comes with multiple working modes to adapt to different job requirements.

Stable Heavy-Duty Build With an operating weight of approximately 11,600 kg, the 312GC adopts an LC long undercarriage design. The extended track frame provides larger ground contact area and superior stability on uneven and soft ground. Reinforced boom, stick and X-frame structure resist heavy digging impact and extend service life.

Versatile Digging & Loading Performance Bucket capacity ranges from 0.53 to 0.80 m³ and maximum digging depth reaches 5,080 mm. The machine efficiently completes foundation excavation, mass earthmoving, backfilling and stockpile loading. Auxiliary hydraulic lines support quick installation of hydraulic breakers for multi-purpose construction tasks.

Efficient Hydraulic System Caterpillar’s advanced load-sensing hydraulic system delivers smooth and precise joystick control. Pressure compensation technology enables coordinated multi-function movements and fast cycle times, improving productivity during repeated digging, slewing and dumping operations. Auxiliary hydraulic flow is available for different attachments.

Serviceable & Operator-Centric Design Ground-level service access points simplify daily inspection and routine maintenance to minimize downtime. The spacious operator cab provides good all-around visibility and ergonomic controls, lowering operator fatigue during long working shifts in various construction environments.
