20ton Hydraulic Crawler Excavator 320GC New Excavators with 1.2m3 Bucket
320 GC excavator not only has excellent productivity, but also provides the following characteristics: easy-to-use technical functions, new comfortable cab, reducing fuel consumption by up to 20% and longer maintenance interval (reducing maintenance cost by up to 20%), so as to provide a durable excavator with low operating cost per hour, which is suitable for light to medium load applications.
1. High performance, low fuel consumption In similar applications, the oil consumption of the excavator is reduced by up to 20% compared with 320d2 GC. Use the power mode to match the excavator with the operation; And automatically match the engine and hydraulic power with your excavation conditions through intelligent mode. The advanced hydraulic system not only achieves the best balance between power and efficiency, but also provides you with the control devices you need to meet your precise excavation requirements. Valve priority allows hydraulic pressure and flow to reach the level you set for rapid light to medium duty cycling. It meets the equivalent emission standard of EPA Tier 3 / EU stage IIIA / China non road country III / Brazil Mar-1. Add an auxiliary hydraulic system to do more with a variety of different ca-t tooling. Product Link. It is a standard accessory, so you can use visionlink as needed. The online interface remotely monitors the operation status, position, working hours and fuel consumption of the machine.
2. Lower maintenance costs Maintenance costs are expected to be reduced by up to 15% compared to 320e (savings based on 12000 machine hours). All routine maintenance work can be performed on the ground. Check the engine oil level quickly and safely with a new engine oil dipstick close to the ground; With a second dipstick within reach, engine oil can be filled and checked at the top of the machine. The filter service life and maintenance cycle of the excavator can be tracked through the monitor in the cab. Maintenance of the ca-t clean emissions module is not required. After 500 hours of synchronization, replace all fuel filters. The new intake air filter with pre filter is expected to last 1000 hours - 100% longer than the previous filter. The new hydraulic oil filter can provide better filtration performance, and the reverse exhaust valve can keep the oil clean when changing the filter, with a replacement interval of up to 3000 man hours and a longer service life - 50% longer than the previous filter design. The new high-efficiency electric cooling fan operates only when needed and can be reversed to eliminate debris on the core. The s · o · s sampling port simplifies maintenance work and can quickly and easily take oil samples for analysis.
3. Stable, reliable and trustworthy The operating altitude is up to 3000 m (9840 ') without reducing the rated power. It can work in high temperature environment up to 52 ° C (125 º f) and cold start capacity as low as - 32 ° C (- 25 º f). The automatic preheating function can increase the heating rate of hydraulic oil in cold weather conditions and help to prolong the service life of components. Triple fuel filtration protects the engine from dirty diesel fuel. The grease seal between the track pin and the bushing can reduce the driving noise and prevent the entry of debris, so as to prolong the service life of the chassis system. The center track guide shield helps keep the excavator tracks aligned when the excavator is traveling and working on a slope. Tilting track frames help reduce the risk of track damage by preventing the accumulation of soil and debris.
