CAT Next-generation CAT®345 GC Hydraulic excavator

1、Bucket

Standard 2.Four square rock buckets，Max. Optional 2.6 square rock buckets；Hyperbolic bucket profile improves digging performance and reduces bottom wear，With clearance adjuster。The side protector can ensure the durability under high friction and high impact conditions.，Reinforced penetrating teeth use more wear-resistant material for sharper profile。

2、Stick boom

Large and small arm sizes available，Provide scope of excavation work similar to 349。

Heavy Duty Stick Pin Base than 349D2. Adopt new appearance and increase internal welding.，New design of boom front end support， Optimized internal stiffener angles and shapes，Pipe base；LEDWork lights

Anneal process treatment is adopt，The structural parts after the robot welding are placed in an annealing furnace to be slowly heated to about 650 deg C，After holding for a period of time, it is slowly cooled to room temperature to eliminate most of the internal stress generated in the manufacturing process.，Reduced risk of deformation and cracking，And that durability is improve。

3、Upper frame

The upper platform is designed with punching and countersunk bolts.，Anti-slip、Flat；Left, right, upper and lower handrails of the complete machine、Pedal、Guardrails are complete and meetISOSafety requirements of 2867 standard for access to construction machinery。

4、New electro-hydraulic system

Inherited from 374/390FThe successful experience of the series of super-large excavators and the widely proven electro-hydraulic main control valves of the new generation of 20 to 36 ton models，High efficiency and low consumption。The pilot pump and the pilot lines are eliminated，The valve body is internally integrated、Realize multiple functions and reduce the risk of external connection pipelines and leakage,

Standard sampling and test port；Valves are marked for use；Single pump flow can fully meet 195mmTool Hammer Requirements，Two-pump confluence configuration available，Hydraulic demand settings and switching for different tooling tools can be easily set via the touch screen display。

5、C9.3B Engine

Since the mass production of the engine core in 2011, the cumulative working time in various working conditions and applications around the world has exceeded 200 million hours.，High pressure common rail fuel injection system with 10 micron and 4 micron dual stage diesel filter elements，At the same time, the Euro IV version came out at the end of 2017.。Diesel、The engine oil filter element is arranged on the right side at the same time for the convenience of one-time inspection or replacement，Save time and improve efficiency。

6、Counterweight

The standard rear-view camera is embedded in the counterweight for full protection.；SunkenLogoProtection design。

7、Cooling cabin

The single-row cooling unit is arranged and ventilated smoothly，On-demand hydraulic cooling fan with high efficiency and low consumption，Fan reverse function available；Standard Coolant Sampling Port；Coolant level check。

8、Electrical compartment

Air cleaner with integrated swirl pre-filter；Under the action of centrifugal force when the intake air passes through the impeller in the swirl pipe,,Filter out the large particles of dust in the intake air。Capacity to hold twice as much dust as the previous generation，Greatly extend the service life of the filter element；2 maintenance-free batteries provided-18°Cold start capability provided-32°Start-up capability

9、Cab

ISOCertifiedROPS；New shock absorbers bring 50%Improvement；All-round vision is improved；Quiet pressurized sealed cab；LEDWork lights；Wider and thicker seats，Handheld code，Custom function handle，Eight-inch touch-screen display provides rear-view image，Knob combined with key operation，No potential leakage inside。

10、Maintenance
