Green Power Strong Output

Since 2015, with the successive launch of Hitachi Construction Machinery 5A new products, more customers have been strongly supported by high-performance power. As an upgrade of large excavator products, Hitachi Construction Machinery ZX890LCH-5A uses Isuzu's original imported engine, which ensures high power output and reduces fuel consumption and overall operating costs to a new low. The engine incorporates a high-pressure common-rail electronically controlled fuel injection system and a cold EGR system. Through precise control of injection time and injection quantity, fuel efficiency is significantly improved, and pollutant emissions are reduced with the help of a cold EGR system. In the face of increasingly stringent industry environmental protection indicators, ZX890LCH-5A meets the country's 3rd emission standards and can easily achieve low-carbon operations.

Hitachi Construction Machinery ZX890LCH-5A is matched with Hitachi HIOS III B hydraulic system to demonstrate excellent work performance. The engine's rated power is up to 377KW, and it offers customers three-speed power mode selection: powerful H/P mode, standard PWR mode and economical ECO mode to meet different working conditions. Compared with the previous generation, its fuel efficiency in the latter two modes is increased by 11% and 9% respectively, which can effectively save operating costs.

Multi-dimensional reinforcement High-durability protection

Hitachi Construction Machinery's design team fully considered the particularity of mine operations and targeted upgrades to key components including engines to achieve greater maneuverability and durability. The ZX890LCH-5A front-end working device adopts R-type reinforced design to increase the strength by thickening the plate and fully welded structure. The upper slewing platform of the D-section frame can resist external impact, and the bearing capacity of the slewing bearing is also enhanced. Smooth rotation is achieved smoothly during operation. For the lower traveling body, the high-strength LC bolt structure enhances the rigidity and stability, and details such as the off-board seal plate and the three-piece rail chain guide structure can effectively cope with various harsh environments.

Safe and reliable Comfort and control

The H/R cab that complies with the OPG top guard II class standard provides reliable protection for operators, protects the safety of personnel when there is a risk of falling rocks, and comes standard with a protective net at the lower part of the front window to raise the safety level in all directions. In the face of a complex surrounding environment, the panoramic view can present a wide field of view, and the addition of the rear camera can present more external information on the monitor, further reducing the probability of occurrence of danger.

The cab is well-spaced and the legs move freely. Ergonomically suspended seats help reduce sedentary fatigue and provide a comfortable environment for long periods of high-load operation. In addition, the layout of the ZX890LCH-5A's control platform is reasonable, and the common control buttons such as monitor switches and air-conditioning switches are all concentrated on the right side, making the operation easy. Among them, the monitor can display the device status, provide the rear image and support the attachment replacement prompt, at a glance.
