For a long time, Hitachi Construction Machinery's medium-sized excavators have been popular in the market for their wide industry applicability and outstanding product performance, and they have continuously promoted new optimizations to enhance their application value. A few days ago, the star model ZX360H-5A ushered in a major upgrade. The new ZX360H-5A Pro will bring customers a more efficient and durable dual quality experience in terms of loading speed, workload, fuel efficiency, and durability.

Hitachi Construction Machinery’s ZX360H-5A series products are known for their efficient operation and economical durability. Their design concepts and various performance indicators are widely recognized by Chinese customers. In order to further strengthen product competitiveness and meet the extreme pursuit of high-efficiency loading by customers of this ton level, the new ZX360H-5A Pro optimizes work efficiency and strengthens the fuselage to speed up the overall loading speed of the equipment by 21% [data from and ZX360H- The theoretical comparison of 5A standard configuration may be different due to different working conditions. ], the fuel efficiency has been increased by 16%1, and the thickness of the track shoes has been increased by 45%1, making it easy to "siege the city".

Hitachi Construction Machinery ZX360H-5A Pro adopts the Hitachi HIOSⅢ hydraulic system with excellent performance, high-efficiency and precise hydraulic control, excellent composite coordination, man-machine integrated controllability, and specially integrated patented technology "Excavation Speed Increase System" and " Boom regeneration system" has greatly increased the operating speed of the front-end device, which is particularly prominent in truck loading operations. The maximum digging force of the bucket is 246kN, and the maximum digging force of the stick is 222kN, which is 20% higher than the standard configuration, plus 2.0m³ large bucket for loading, 10.7 min-1 (rpm) rapid rotation, new large-scale power Multiple optimizations of the model can achieve a 26% increase in workload1 and a 16% increase in fuel efficiency1, helping customers to speed up, increase efficiency, and reduce costs.

In addition to the breakthrough in operational efficiency, ZX360H-5A Pro has also been substantially enhanced in terms of durability. Compared with ordinary reinforced crawlers, Pro is equipped with a super-reinforced lower walking body, and the thickness of the track shoe is increased by 45%; at the same time, it is optional The full track chain guide mechanism can reduce the wear and deformation of the track chain and the supporting wheels, and make the durability of the lower walking body more excellent. In addition, the core components such as the engine, hydraulic pump, multi-way valve, slewing ring and so on are imported from original packaging with high quality and durability. In particular, the third-generation Isuzu 6HK engine is adopted, and the fuel injector and high-pressure pump are comprehensively enhanced and upgraded to improve the durability of the engine. All-round strengthening design ensures that the machine can display its outstanding nature for a long time.

In terms of driving experience, humanized configurations such as a large pressurized cab with open space, suspension seats with excellent shock absorption, and a multi-functional monitoring system that can check machine status from time to time can effectively improve driving comfort and ease long-term work belts. Coming fatigue. The design of the central pillar reinforced structure cab and neutral engine starting system provide safety guarantee for comfortable operation. In addition, ZX360H-5A Pro continues the high-quality maintenance module design of Hitachi excavators: the main fuel filter, pre-filter, pilot filter, oil filter and electric fuel pump are concentrated in the pump room, saving time and effort for maintenance operations; using expansion tanks and cooling circuits Completely airtight, no need for frequent filling of coolant; multi-stage fuel filter system prolongs the service life of the filter and reduces later use costs; the fuel tank drain valve, oil drain port, and the large-size clean port at the bottom of the fuel tank are used for inspection and maintenance It's convenient.
