22 Ton Crawler Excavator
This 22-ton crawler excavator is an efficient, energy-saving, and stable and reliable piece of engineering machinery. It adopts a reinforced structure and an intelligent hydraulic system, significantly increasing digging force by 11% and reducing fuel consumption by 5%-8%. Combined with its convenient maintenance design, it fully meets the demands of high-intensity operations.
Product description:
The SH220-8 hydraulic excavator is designed to provide operators with a safer and more comfortable working experience. It features a newly designed cab with excellent visibility and significantly reduced interior noise, creating a quieter and more comfortable operating environment. An optimized silicone oil damper effectively minimizes vibration, further enhancing operational comfort. The cab is also equipped with an imported high-performance air conditioning system and an integrated control panel, ensuring user-friendly operation and efficient temperature control.
The multi-directional adjustable seat can accommodate different body types and operating habits, effectively reducing fatigue during long hours of work. In terms of safety, the SH220-8 comes standard with a ROPS-compliant anti-rollover cab, greatly improving operator protection. Optional cab protective nets and anti-collision side beams are available to enhance operational safety in demanding working conditions such as mining.
Additionally, the internal and external air filter elements of this model are easy to remove and clean, helping to maintain high air quality inside the cab. The machine is also equipped with a negative battery switch, allowing for quick power disconnection to facilitate maintenance and long-term parking.
