YD22 Crawler Excavator
Our YD22 crawler excavator has an operating weight of 2.2t, a maximum digging radius of 4,220mm, a maximum digging depth of 2,500m, a maximum digging height of 3,650m and a maximum dumping height of 2,265mm. Because of its small size, this engineering machinery fits in narrow spaces. Its semi-enclosed cab increases the driver's comfort. This economical and practical hydraulic crawler excavator has the following features:
Features
1. This cost-effective excavator is equipped with a powerful engine that is made by well-known Chinese manufacturers and meets requirements for efficient working capacity.
2. A special funnel cover increases the air flow rate of the engine and the cooling capacity of the system, ensuring that the crawler excavator continues to work effectively.
3. A precise matching design and advanced energy saving controls gives the excavator a high response speed while using less fuel.
4. Its emissions comply with Euro II standards.
5. A new model of cooling fans and a silencer lessens the noise the excavating machine makes.
6. Advanced turbocharging technology allows our crawler excavator to be used for plateau operating.
7. This crawler excavating machine is configured with high quality main pumps, main valves, motors, oil cylinders and other key components purchased from well-known manufacturers.
8. Higher torque reserve gives our excavating equipment a more powerful swing capacity. Its ability to absorb vibration ensures the swing motion stops precisely and stably.
9. The hydraulic oil cylinders used for our crawler excavator are designed with a buffering function, which not only lowers the noises and reduces the vibration of the machine, but also helps extend the service life of the cylinders.
10. Double pump interflow technology is used to increase the flow from the main valve to the cylinders, so the crawler digger can work at a faster speed.
