The Hitachi ZX120 excavator is a powerful mechanical equipment with the following main technical parameters:
The working weight of the entire machine has reached an astonishing 12200 kilograms, with a bucket capacity of 0.52 cubic meters, a boom length of 4600 millimeters, and a boom length of 2520 millimeters. This excavator comes from Hefei, Anhui, China and exhibits extremely high quality of origin.
In terms of performance, its turning speed reaches 13.7 revolutions per minute, and its walking speed is divided into two modes, namely 3.4 kilometers per hour and 5.5 kilometers per hour. In terms of climbing ability, it can operate stably on a 70% slope and easily handle a 35 ° slope. The grounding pressure of the excavator is maintained at 37 kPa, ensuring excellent stability and excavation efficiency.
The CC-4BG1TC engine provides power for excavators, with a rated power of 66 kW, a speed of 2150 rpm, a displacement of 4.329 liters, equipped with 4 cylinders, and cooled by water cooling. In addition, it also adopts direct injection technology to improve fuel efficiency and performance.
The hydraulic system is equipped with variable piston pump x 2 and gear pump x 1, with a main relief set pressure of 34.3 megapascals. The walking hydraulic motor is a variable displacement piston pump x 2, and the rotary hydraulic motor is a fixed displacement piston pump x 1, ensuring precise and efficient hydraulic operation. Unfortunately, hydraulic fracturing pipelines are not included as standard equipment.
Other key parameters include a fuel tank capacity of 250 liters, a full hydraulic tank capacity of 130 liters, and an engine oil change volume of 15.8 liters. The main dimensions of the excavator during transportation are a total length of 7610 millimeters, a width of 2490 millimeters, and a height of 2740 millimeters. The full height of the cab is also 2740 millimeters, with a ground clearance of 890 millimeters for the counterweight, a track gauge of 1990 millimeters, a minimum ground clearance of 440 millimeters, and a rear turning radius of 2130 millimeters.
In terms of the scope of work, the maximum excavation radius is 8270 millimeters, the maximum excavation depth is 5570 millimeters, the maximum excavation height is 8570 millimeters, the maximum unloading height is 6160 millimeters, and the maximum vertical excavation depth is 5020 millimeters. Unfortunately, the bulldozer lifting or deepening function is not available
