Used Hitachi Zaxis 200 Excavator Cheap Price Medium Used Digger 20 Ton Second Hand Excavator

Hitachi ZX200 series excavators are medium-sized hydraulic excavators suitable for a variety of operating scenarios such as construction, mining, and forestry. The following is a comprehensive description:

1. Basic parameters and model differences

Machine weight: The basic model ZX200 has an operating weight of approximately 19,400–20,500 kg, which varies depending on the configuration.

Engine:

ZX200: Equipped with ISUZU AA-6BGIT engine, rated power 109.6–112 kW.

Emission standards: Some models meet Tier 3/Stage IIIA standards and use turbocharging and intercooling technology.

2. Performance characteristics

Operation capacity:

Maximum digging depth: 6,550–6,670 mm, maximum digging height approximately 9,600–9,610 mm18.

Travel speed: 3.0–5.5 km/h, climbing ability up to 70% (35°).

Swing speed: 13.3–13.5 rpm, providing flexible operational response.

Hydraulic system:

Equipped with Hitachi's patented HIOSⅢ hydraulic system, supporting "excavation speed increase" and "boom regeneration" functions, increasing operating speed and reducing fuel consumption.

Optimize hydraulic pump control to achieve precise power distribution and reduce energy loss.

3. Design and durability optimization

Structural reinforcement:

The front working device uses tungsten carbide injection technology to reduce wear, and the bucket and boom connection uses HN bushings to improve durability.

The lower walking body adopts an integrated welded X-beam structure to enhance the overall strength, and the track tensioning mechanism absorbs impact.

Cab design:

Wide-view cab, increased front and side window glass area, reasonable layout of the control panel, standard suspension seat and pressurized dustproof design.

Equipped with a 7-inch multi-function monitoring system, supporting rear camera and night mode switching.

4. Maintenance and applicable scenarios

Maintenance convenience:

Maintenance parts are centrally distributed, and the fuel tank, filter and other vulnerable parts are designed to be easy to replace. The dust screen and radiator can be quickly cleaned.

Hydraulic oil coolers are set in parallel to simplify engine peripheral maintenance.

Applicable scenarios:

The basic model is suitable for conventional earthworks; ZX200-3G is designed for in-ship loading and unloading and is equipped with a wide bucket; ZX200-5G is optimized for high-intensity operations and is suitable for mines and complex terrain
