[China Road Machinery Network original report] In the construction of the project, the driver's remote control operation of the concrete pump truck is still relatively common on the construction site, but in the special working conditions, the driver's safety is threatened. , remote control engineering machinery and equipment has become a protector!

How to ensure the safety of the driver in dangerous working conditions

In the construction of various special working conditions such as earthquake relief, toxic environment, dangerous tunnels, fire fighting and rescue, cliff opening, and explosion site cleaning, the engineers face great dangers, life is priceless, how can drivers After completing construction and rescue operations, can they protect their bodies from threats?

The combination of remote control technology and engineering machinery can solve this problem well.

The combination of remote-controlled driving technology and engineering machinery enables engineering machinery to penetrate deeper into more complex and dangerous construction environments, freeing people and improving job safety.

Intelligentization in construction machinery at home and abroad has become an important indicator for improving product performance and reflecting the technological content of products. The application of remote control driving technology is also one of the important manifestations of the development of intelligent engineering machinery.

As the remote-controlled driving technology becomes more and more mature, in the construction machinery industry, the most powerful foreign top manufacturers Caterpillar, Komatsu and domestic Sany, Xugong, Shanhe Intelligent, Shantui, SINOMACH and other first-line brands They have developed their own remote-controlled driving engineering machinery products.

Caterpillar: Free operation thousands of miles away

In the era of smart machines, Caterpillar's research on remote operations has never stopped. Through repeated technical research and customer feedback, Caterpillar's remote operating system effectively reduces the exposure of operators to hazardous environments, making construction easier and more enjoyable, helping companies maintain productivity while achieving safety. The goal of production.
2,200 kilometers (1,400 miles), equivalent to the distance from Beijing to Guangzhou, it takes 24 hours to drive and 3 hours for the plane. Remote operation of a Cat® D8T track-type tractor at such distances can be done in real time. This is not a science fiction film, but an application scenario for the latest Cat® remote operating technology.

Start, accelerate, turn, brake... The "unmanned" big machine can do almost everything with remote operation technology! Whether it's an integrated operator console or a portable operating handle, the operator can more fully evaluate the operating terrain and remotely and continuously control the device through a remote operating system. More importantly, such a sci-fi technology is not used to “frighten people”, but to allow construction workers to stay away from dangerous job sites, making construction safer and more comfortable!

A Cat® data link technology that is deeply integrated with the machine monitoring system, even if you don't go out, engineering managers can track machine position, hours of operation, fuel usage, productivity, etc. in real time using Cat® smart technology. Information, supported by data, maximizes job efficiency, increases productivity and reduces costs.

Ryan Newman is a racer in NASCAR, the most popular motor sport in the United States. During the NASCAR 2015 Phoenix City Tournament, Newman experienced the fun of remotely driving a Caterpillar bulldozer 200 km away via a telecommunications network. The system is installed in a trailer with the same hardware and bulldozer simulator, except for the seat and operating handle, including two large screens and a small screen, one of which shows the scene of the bulldozer. The other screen displays the front, back, left front and right front of the bulldozer in separate screens, and the smaller screen simulates the dashboard of the bulldozer. Unlike the bulldozer simulator, the displayed picture and the transmitted commands are all true, driving a real machine.

Newman was outside the Phoenix stadium, while the Carter D11T bulldozer was driving at the Caterpillar Test Site south of Tucson. Newman experienced walking and dozing work under the guidance of Caterpillar experts, claiming to feel great. Of course, this is Caterpillar's activity to showcase its mine intelligence technology COMMAND, so the experience people have come to addiction.

Komatsu: drone + unmanned bulldozer, excavator

Komatsu has been actively utilizing global positioning systems (GPS) and sensors to develop machinery that enables unmanned and automated operation. In 2008, Komatsu developed an unmanned operation system for a very large dump truck that was efficiently driven on a fixed route in the mine.

In response to the aging population and the shortage of labor, at the ConExpo show in 2014, Komatsu Group displayed its new member of the intelligent machine control technology, PC210LCi-10, which was officially launched into the market in November of that year. Komatsu called it the world's first intelligent machine control technology (IMC) machine.

KOMATSU's Smart Construction uses a drone-guided autopilot bulldozer to automatically excavate dirt and stones without the need for manual driving. According to Verge, the principle of the system works is that the drone draws a 3D topographic map and provides real-time updated data for the bulldozer to track the amount of sand and cement excavated. Then calculate the most efficient construction plan for engineering equipment such as excavators.

  

Komatsu's bulldozer products with intelligent machine control technology (IMC)

Komatsu invested $2.5 million in Skycatch, a UAV manufacturer in Silicon Valley, USA, in the hope that it will be able to use the drone with its own machine bulldozers and remote operations teams to complete the construction work in the future. Komatsu’s previous unmanned bulldozers, excavators and dump trucks also included drones, which enabled cutting-edge technology and saved a lot of time.

Volvo Construction Equipment: Conceptual Equipment Leads the Era

At the 2017 Las Vegas International Construction Machinery Show, Volvo Construction Equipment demonstrated the battery-powered HX2 automated loader. This second-generation concept device is part of an electrification field-based project that aims to achieve a revolution in quarrying by reducing carbon emissions by 95% and total cost by 25%.

Volvo's HX2 automated loader

The HX2 is very different from the HX1. The HX1 is just a proof of concept machine. After we determined that the project was feasible, the HX2's design requirements were updated and the Volvo Group's shared technologies and components, such as electric motors, batteries and power electronics, were used. To fully utilize the pioneering R&D results of the Volvo Group in the field of electric technology, it is essential to design a new powertrain system. Another new feature is the addition of a vision system that allows the machine to detect people and obstacles around it.

As early as September 2016, at the Discovery Forum in Eskilstuna, Sweden, Volvo Construction Equipment introduced the HX1 automated electric loading concept car with a new concept. The loader prototype is part of a field-based electric system research project. The project aims to achieve transport electrification in the quarry, including the entire process from excavation to primary crushing to secondary crushing. The project includes the development of new machines, working methods and on-site management systems.

Volvo HX1 automated electric loading concept car

The project was launched in October 2015 and is expected to be completed by the end of 2018. Volvo Construction Equipment is currently developing and testing related technologies, concepts and prototypes. At the end of 2018, Skanska Sweden will integrate the demonstration machine into its actual operation and conduct a 10-week test of the field-operated electric system at a quarry in western Sweden. Volvo Construction Equipment will then review the project results to determine if the relevant concepts are suitable for use in the industry. Currently, this work is only a research project and there is no industrialization plan.

JCB: Customized version of the remote control excavator for removal

In 2015, JCB developed a unique remote-controlled excavator, a specially tailored device for the professional demolition industry of Birmingham Coleman.
