Used Hitachi ZAXIS 350H Heavy-Duty Excavator for Sale

The used Hitachi ZAXIS 350H excavator is built for buyers who need a strong 35-ton-class machine for demanding earthmoving work. The unit shown in the photos carries the ZAXIS 350H model marking and features a heavy crawler undercarriage, reinforced working structure, enclosed operator cab and large hydraulic excavating system.

The H-series was developed for tougher digging applications such as quarrying and heavy excavation. Hitachi describes its H-series machines as heavy-duty excavators equipped for demanding digging environments.

For construction contractors, quarry operators, equipment dealers and rental fleets, a well-inspected used ZAXIS 350H offers a practical way to add heavy excavation capacity without the investment required for a new machine.

Hitachi ZAXIS 350H Reference Specifications

The photos identify the machine as a ZAXIS 350H. However, production year, serial number, arm configuration and attachments should be checked before the final quotation. Standard ZAXIS350H technical data lists an operating weight of about 32,900 kg with a 3.2 m H arm and a 1.38 m³ PCSA heaped bucket.

Reference values can vary with production year and configuration, so buyers should confirm the individual machine data before purchase.

Heavy-Duty Design for Tough Job Sites

The key advantage of the Hitachi 350H excavator is its heavy-duty configuration.

Compared with machines intended mainly for standard earthmoving, the ZAXIS H-series is designed for jobs involving harder material and longer duty cycles. Its crawler base gives the machine a wide and stable working platform, while the reinforced front structure supports demanding digging operations.

Therefore, this used excavator is well suited to quarry work, large foundations, road construction, bulk excavation and infrastructure projects.

The 600 mm grouser shoes also provide a good balance between ground contact and transport width in the standard configuration.

Isuzu Diesel Power for Heavy Excavation

Reference specifications for this generation of ZAXIS 350H list the Isuzu AA-6HK1X diesel engine.

The engine delivers around 177 kW at 1,900 rpm, with higher output available in H/P operation.

For a used machine, however, engine condition is more important than the original rating alone. Therefore, buyers should check:

• Cold-start performance
• Exhaust smoke
• Engine sound
• Oil leakage
• Cooling system
• Turbocharger condition
• Operating temperature
• Engine response under load

Longmai can provide current machine photos and operating information according to available stock, helping overseas customers evaluate a unit before shipment.

Stable Crawler Undercarriage

A heavy excavator often spends long hours digging while carrying high loads through the boom and arm. For this reason, undercarriage condition directly affects stability, service life and future maintenance costs.

The ZAXIS 350H uses a wide crawler system with a reference undercarriage width of approximately 3,190 mm and standard 600 mm grouser shoes.

Before buying a used unit, important wear points include track shoes, track links, rollers, carrier rollers, sprockets and idlers.

The photos of the available machine can also be used to evaluate visible track condition, while a closer mechanical inspection provides a clearer picture of remaining service life.

Hydraulic System for Productive Digging

Large excavation work requires smooth hydraulic response as well as engine power.

The ZAXIS 350H hydraulic system supports boom, arm, bucket, swing and travel operations under heavy working conditions. This allows the machine to perform repeated digging and loading cycles efficiently.

Depending on the individual unit's auxiliary hydraulic configuration, the excavator can also be prepared for different attachments, such as:

• Heavy-duty digging buckets
• Rock buckets
• Hydraulic breakers
• Rippers
• Grapples
• Pulverizers
• Other project-specific attachments

Attachment size and hydraulic compatibility should be confirmed before installation.

Enclosed Cab for Long Working Shifts

The machine shown has a full enclosed operator cab with broad glass areas and protective guarding.

Inside, the excavator uses hydraulic joystick controls and an adjustable operator seat. The enclosed structure also provides better protection from dust, wind and jobsite conditions than an open operator station.

For contractors operating multiple shifts, cab condition is an important part of machine selection. Buyers can request checks of the controls, instrument panel, air-conditioning system, seat, windows and electrical functions.

Applications for the Used Hitachi 350H

With its approximately 33-ton operating weight and heavy-duty design, the ZAXIS 350H can serve a wide range of professional projects.

Typical applications include quarry excavation, road and bridge construction, industrial foundations, pipeline projects, land development, bulk earthmoving, demolition preparation, stone handling and large commercial construction.

It is particularly suitable for buyers who need more digging capacity than a 20-ton excavator but still want a machine that remains practical for regional transport and general infrastructure work.
