1. ICT Hydraulic Excavator
Hitachi Construction Machinery Co., Ltd. released the ZX200X-5B hydraulic excavator, which is equipped for construction assisted by information and communication technology (ICT), as a forerunner in the upcoming era of the Internet of Things (IoT).
In ICT-assisted construction with the use of a hydraulic excavator, operators are provided with guidance on the positional relationship between the machine and the construction target plane, and control is implemented to prevent the machine from intruding into the target plane. This excavator is equipped with a machine control function and a guidance function so that the machine, or its front part, will be semi-automatically controlled on a real-time basis based on the position and attitude information of the machine from the satellite positioning and attitude sensors and the three-dimensional (3D) design data on the construction target.
The main features are as follows.
- Equipped with a function that prevents excessive excavation beyond the target plane and with a machine control function that maintains the bucket angle for facilitating operations.
- Equipped with an original two-dimensional (2D) machine guidance system that is easy to introduce, even in small-scale construction work.
- Provides four different functions, namely 2D and 3D machine guidance and 2D and 3D machine control, in collaboration with an external 3D machine guidance system.
In the future, the company will expand its model lineup and promote it on the global market.
