BOOM CYLINDER 204-2823 For Cat365C Excavator

BOOM CYLINDER 204-2823 For Cat365C Excavator

The 365C Cat boom cylinder adopts a dual-cylinder symmetrical layout, with a single cylinder bore of 190 mm and a stroke of approximately 1790 mm. Driven by 32 MPa high-pressure oil, it supplies stable lifting force and precise control for this 66-ton "giant". It is the core actuator to ensure high-efficiency heavy-duty operation in mines.

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.

Q&A

 
 

 

 Cat boom cylinder

What is the standard fuel consumption of the 365C?

Under standard heavy-duty digging conditions, for Cat boom cylinder average fuel consumption is approximately 28–32 L/h, depending on load rate and operating habits.

 

What should be inspected primarily on used equipment?

Focus on checking engine leaks (oil, water, gas), abnormal noise from the hydraulic pump, swing bearing clearance, and repaired welds at the boom root.

What are the advantages over the 336D?

The 365C is a 60-ton-plus class excavator, with significantly higher power, digging force and stability than the 336D (approx. 40-ton class), making it ideal for larger-scale mines or deep foundation pit projects.
