High Quality Used Excavator HITACHI Zx250 ZX250H-3 Used Excavator 25Ton ZX250-3 Hydraulic Digger Crawler Excavators for Sale

Comprehensive description of Hitachi ZX250 series excavators:

I. Basic parameters

Working weight: 24,500-25,400 kg.

Power system

Engine: Equipped with Isuzu inline four-cylinder or six-cylinder turbocharged engine (such as GH-4HK1X), rated power 127-148 kW (170-200 PS), supports low-temperature start and low fuel consumption design.

Fuel economy: With electronic direct injection technology, cold EGR system and variable turbocharger, the fuel consumption of some models is 9%-10% lower than that of the previous generation.

Hydraulic system

Main pump: Dual variable axial piston pump, maximum flow 2×204-224 L/min, working pressure 34.3-34.8 MPa, combined with HIOS III or TRIAS III hydraulic technology to improve work efficiency.

Excavation performance

Bucket capacity: Standard configuration 0.6-1.4 m³.

Digging depth: The maximum digging depth of conventional models is 6,170-6,960 mm, and the extra-long front-end model can reach 14,465 mm.

Digging force: bucket digging force 188 kN, digging force of digging arm 125 kN, traction force 203 kN.

2. Performance characteristics

Structural reinforcement design

Lower walking body: The X-beam structure is strengthened by 35%, and the track chain is thickened by 10%, which is suitable for harsh working conditions such as mines.

Front-end device: The boom and digging arm adopt a reinforced design, and the key parts (such as the end of the digging arm) are applied with WC melting technology to significantly improve wear resistance.

Intelligence and operation experience

Cab: Equipped with CRES cab, integrated air conditioning, air suspension seat and low noise design (vibration reduced by 20%), and humanized operation interface.

Hydraulic control: Supports automatic power boost, digging arm regeneration system and automatic idling function to optimize operating efficiency and fuel consumption.

Environmental protection and safety

Emission standards: The National IV model (ZX250-6A) adopts a DOC+SCR post-treatment system and meets the National IV emission standards; other models (such as LC-5A) meet the National III standards.

Safety configuration: Equipped with overload warning, rollover protection and status monitoring systems to ensure safe operation.

III. Applicable scenarios

Mining operations: The reinforced structure and high excavation force are suitable for ore excavation and heavy load handling.

Municipal engineering: The compact body (tail turning radius 2,750-3,140 mm) is suitable for narrow spaces such as urban pipeline laying and greening construction.

Deep pit and river operations: The ultra-long front-end model is specially designed for deep trenches and river dredging, with a maximum excavation depth of 14.5 meters.

IV. Market comparison and precautions

Competitive product comparison: Compared with models of the same tonnage (such as Caterpillar 320), the ZX250 series has more advantages in structural strength, hydraulic system stability and fuel economy, but the intelligent configuration is relatively simple.

Configuration differences: Different sub-models have differences in parameters such as engine power, hydraulic flow, working weight, etc. It is recommended to refer to the official manual or dealer information.
