Hitachi EX1900 Bucket For Hitachi Excavator

In a large commercial complex construction project in a southern city, the construction team faced extremely complex and high-intensity excavation challenges. The project site was originally an old urban area with complex underground pipelines and surrounding buildings that were still in use, which placed extremely high demands on the accuracy and safety of the excavation work.

At the beginning of construction, digging ordinary soil and demolishing the ruins of old buildings were the top priorities. At this stage, the visual design of the Hitachi EX1900 bucket played a key role. Its unique shape and structure reduce visual blind spots. With the high-definition camera and large-size display on the excavator, the operator can clearly see the surrounding environment of the bucket, including the direction of underground pipelines and the distance from surrounding buildings. When excavating an area close to an old residential building, the operator used the visual system to accurately control the bucket movement, successfully avoiding the impact on the foundation of the residential building, and efficiently completing the excavation task, which made the on-site supervisor and residents feel very relieved.

As the project progressed, the construction team encountered a hard rock layer. This problem put forward higher requirements on the durability and stability of the bucket. Fortunately, the Hitachi EX1900 bucket is made of high-strength steel, and the overall structure is sturdy and durable, which can easily cope with this challenge. Its solid frame effectively resists the strong impact force generated when excavating rocks, and prevents parts from loosening or falling off due to deformation under force. During the continuous weeks of rock excavation operations, the bucket has always operated stably, which not only reduces the risk of accidents on the construction site, but also creates a reliable working environment for operators, effectively ensuring the progress of the project.

However, in a narrow construction site, multiple machines and equipment are operating at the same time, and the space is very cramped. At this time, the precise control advantage brought by the high adaptability of the bucket and the hydraulic system of the whole machine is highlighted. The operator can accurately control the digging depth, angle and rotation of the bucket through the joystick, so that the bucket can accurately reach the target position and avoid collisions with surrounding obstacles and other mechanical equipment. In the process of lifting large construction materials, cranes, concrete mixers and other equipment frequently come and go on the site. The EX1900 bucket relies on precise control and flexibly shuttles among them, efficiently completing the excavation and loading operations without any collision accidents, greatly improving the safety and operation efficiency of the construction site.

At the end of the project, the construction team needed to excavate a large amount of earth for the basement construction, and the construction time was tight. At this stage, the optimized bucket design of Hitachi EX1900 bucket showed its strength. Its unique curve and tilt angle allow materials to enter the bucket more smoothly during shoveling, reducing accumulation and residue, and the shoveling capacity per time is 15% - 20% higher than that of ordinary buckets. When unloading materials, the materials can be unloaded quickly and thoroughly to avoid sticking to the bucket wall. Taking advantage of this advantage, the construction team worked day and night and successfully completed a large amount of earth excavation tasks within the specified time, winning valuable time for the subsequent construction of the project.

In addition, the convenient maintenance design of the Hitachi  bucket also brought great convenience to the construction team throughout the project cycle. Each connecting component adopts a standardized and modular design, and wearing parts such as pins and bushings have quick-change interfaces, so maintenance personnel can quickly complete the replacement. Moreover, the internal structure of the bucket is reasonably laid out, which is easy to clean and inspect, and potential problems can be discovered and handled in time. Therefore, during the entire project, the downtime caused by bucket maintenance was greatly shortened, and the equipment always maintained a good operating condition, which effectively guaranteed the smooth progress of the project.

In this large-scale commercial complex construction project, Hitachi EX1900 bucket has successfully completed various complex and arduous excavation tasks with a series of advantages such as visual design, stable structure, precise control, efficient bucket type and convenient maintenance, and has become a strong guarantee for ontime delivery of the project.
