Caterpillar 365C
Specifications:
Engine Model: Cat® C15 ACERT™
Net Flywheel Power: 302 kW
Operating Weight: 65960 kg
Track
Number of Shoes - Each Side - Long Undercarriage: 47
Number of Carrier Rollers - Each Side: 3
Number of Track Rollers - Each Side - Long Undercarriage: 8
Powerful Performance & High Fuel Efficiency
Equipped with the C15 ACERT electronic control engine can reach 306 kW of power, equipped with an advanced hydraulic system, it achieves strong breakout force while significantly reducing fuel consumption per unit of work.
Strong Structure & Long Service Life
The cat boom cylinder and arm are constructed with high-strength steel plates and box-section design, with key pivot points reinforced to withstand heavy-duty digging stresses and extend service life.
Precise Control & High Efficiency
The hydraulic system features fast response and smooth combined movements, with a swing speed of approximately 6.5 rpm. Matched with a large-capacity bucket, it achieves short truck-loading time and high productivity.
Easy Maintenance & Controllable Costs
Centralized lubrication points and the open engine hood design allow easy access for daily inspections. The electronic monitoring system provides real-time maintenance reminders, reducing the risk of improper operation.
Work efficiency
Core Loading Equipment in Mining Scenarios
In open-pit coal mines and quarry operations, the 365C is typically matched with 40–50 ton mining trucks (e.g., Cat 773). With an arm digging force of 256 kN, the excavator can efficiently break compacted materials and realize rapid truck loading, serving as a key hub in the continuous mining operation chain.


Lifting Auxiliary for Foundation Construction
Relying on its 70-ton-class stable undercarriage and precise hydraulic flow control system, the 365C Cat boom cylinder can undertake auxiliary construction tasks such as pipe gallery laying and large precast component lifting. This multi-functional application capability effectively reduces the equipment scheduling costs of construction projects.
Stable Platform for Breaking
When equipped with a heavy-duty hydraulic breaker, the excavator's reinforced undercarriage and hydraulic accumulator system can withstand high-intensity impact loads. It is suitable for secondary rock breaking operations in mining and demolition operations of old buildings and structures.
