Future initiatives

In FY2017, we delivered new products and new ICT/IoT-based solutions in order to address various challenges at work sites including improved safety, improved productivity, and reduced life cycle costs. Going forward, we will continue to address the various challenges faced by work sites, particularly real-life testing for the commercialization of an autonomous haulage system for dump trucks at mining sites as well as advancing solutions for site management optimization.

Towards the Commercialization of an Autonomous Haulage System for Mining Trucks

Ensuring worker safety at mining sites where huge mining trucks operate is a major challenge. At the same time of ensuring safety, it is also necessary to streamline mine operations through total optimization leading to improved productivity and reduce life cycle costs. As one solution to this challenge, HCM offers an Autonomous Haulage System (AHS) for mining trucks.

AHS enables unmanned operation of mining trucks, which normally require the most manpower, at open-cut mining pits and provides integrated management using its control system. AHS is expected to minimize human error and improve safety, while yielding economic benefits, including reduce human exposure to Safety hazards, lowered personnel costs, increased hours of operation, and reduced fuel costs. HCM’s AHS applies know-how and Hitachi’s technologies in railway operation management, including block train control technology. Blockage management system divides the route mining trucks travel autonomously into multiple zones and permits only one truck per zone. Trucks haul autonomously within their permission zones without communicating with the control system, and only make contact with the system as they approach the next zone. The communication traffic volume is controlled to enable hauling permits to be given for each new zone. This fixes the issue of limits on the number of controllable mining trucks due to communication traffic volume and allows more mining trucks to be controlled.

In FY2017, we performed various verification testing performed at a location in Australia aimed at commercialization. We plan to conduct user tests at customer sites in FY2018 and tests for commercialization in FY2019.

* Open-cut mining pit: A method of mining where minerals are mined directly from the surface without digging a mine shaft.

Practical various verification testing aimed at commercialization will get underway in FY2019

Release of the ZX200X-6 Hydraulic Excavator, a Core Contributor to ICT Construction

In January 2018, HCM released the ZX200X-6 ICT hydraulic excavator, an all new addition to the ZAXIS-6 series and core ICT Construction solution. The ZX200X-6 features a proprietary system for ICT Construction that includes a machine guidance function indicating the location and position information of the machine and work target as well as Solution Linkage Assist, a machine control function that semi-autonomously operates the machine based on work target data.

The ZX200X-6 carries out work in a highly accurate and efficient manner thanks to its over-dig prevention function that controls the bucket so that it does not dig deeper than the work target and bucket angle hold mode that keeps the bucket at a pre-set angle. Compared to the previous ZX200X-5B, the ZX200X-6 offers better finishing capacity and improved workload by around 35% thanks to quicker work.

The ZX200X-6 also greatly increases productivity even on small sites and sites with no GPS signal because of its 2D capabilities. Furthermore, the machine can be upgraded easily from 2D to 3D simply by adding a dedicated 3D device. This enables the ZX200X-6 to be used in a wide variety of regions and fields.

Solution Linkage Mobile - work site visualization tool

HCM developed Solution Linkage Mobile, offering work site visualization, progress management, and proximity notification functions, as one of the ICT Construction solutions of Solution Linkage for improving safety and productivity on construction sites. We began providing Solution Linkage Mobile services in Japan from April 2018.

Solution Linkage Mobile was developed based on the concept of making it easier to use IoT at work sites. This solution connects machinery and people at work sites using mobile terminals such as a smartphone. For example, a mobile terminal is installed on a construction machine or dump truck operating at the work site. Location information uploaded to the cloud through an application is used to plot the position of each machine on a map. Conventionally, site managers examined work arrangements after checking the situation by telephone or other means. Now with this solution, they can use work site visualization to see in real time the location of machines and people, making it possible to increase the efficiency of work.

In real-life testing with the cooperation of customers, this solution improved work site productivity by around 10%. Productivity can be increased even further by linking this solution with ConSite, a service that conveys a machine’s operating condition and breakdown information in a timely manner.

Utilizing ICT Demonstration Site to experience ICT Construction and various solutions first hand

The HCM Group operates the Hitachi Construction Machinery ICT Demonstration Site in order for customers to realize the benefits of ICT Construction processes based on a clear understanding of i-Construction being advocated by Japan’s Ministry of Land, Infrastructure, Transport and Tourism.

Opened in October 2016 at HCM’s Hitachinaka Works, this area deepens customer understanding of i-Construction through demonstrations and training, ranging from surveying using unmanned aerial vehicles (UAV) and laser scanners to explanations of ICT construction machinery functions and technologies, and use of software for creating 3D data. Here, customers get to experience various solutions using the latest technologies of our business partners. In FY2017, around 1,400 customers visited this demo site.

Furthermore, in April 2018, HCM newly opened the Hitachi Construction Machinery Kagawa ICT Demo Site at the Shikoku Branch in Zentsuji City, Kagawa Prefecture, as the second demo site. The HCM Group will use these two sites to foster understanding among customers about the benefits of ICT Construction for greatly reducing conventional processes and increasing both safety and productivity. This will position us to deliver the optimal solutions to customers.

ConSite OIL - 24-hour health monitoring of construction machinery

In October 2017, HCM began offering ConSite OIL in Europe ahead of its worldwide launch. This new solution utilizing ConSite’s automated reporting system monitors the engine oil and hydraulic oil conditions of machinery in operation 24 hours a day and issues automated notifications to customers and service staff at dealers.

This solution analyzes engine oil and hydraulic fluid conditions of machinery, making it possible to understand the overall “health condition” of machinery, including not only oil conditions, but also the condition or breakdown of parts and components. Generally, oil is removed directly from the machine and sent off for analysis to monitor conditions, but ConSite OIL is able to monitors oil performance all time by using sensors. The Global e-Service is used to assess data on oil degradation or contamination based on indicators such as temperature, viscosity, density, and dielectric. When a reading out of the ordinary is detected, dealer staff promptly propose to customers the suitable maintenance, repair or parts replacement.

By innovating ConSite OIL, customers have increased their advanced detection rate of breakdowns occurring in their machinery from 20% to 37%. HCM is now working on developing the next ConSite service following the success of ConSite OIL. Our ultimate goal is to increase the advanced detection rate to 90%.
