The challenge of mobile machines

Mobile machines differ from stationary machines in many ways:

  • They are used outdoors, in almost any weather and in sometimes very harsh conditions such as forests, quarries, tunnels, mountains.
  • The load ranges of the assemblies of off-road machines are very different and very dynamic.
  • The dimensioning of mobile machines is subject to many constraints (weight, energy consumption, size, road traffic regulations, etc.).
  • The manufacturers (OEM) are often SMEs to medium-sized companies and produce small to medium quantities.
  • Functionality, automation and software content are constantly increasing. Operation is becoming more complex, and at the same time there is a lack of skilled workers who can master this complexity.
  • Many machines are used by service providers.
    Order-related billing is becoming more and more important.
  • Local support is often covered by partners whose competences as service providers for different manufacturers are very limited.
  • "Fire brigade missions" by the OEM can be very expensive due to a remote location.

The solution: Connected Mobile Machine

To deliver on the performance promises of mobile machines, powerful designs and intelligent system solutions are first required. But to ensure availability and performance in operation, remote access and remote mo-nitoring are essential. We offer a complete solution from a single source in cooperation with Ardexa. 

Essential core functions of this IoT solution are:

  • Remote access via mobile radio and telematics module, incl. remote shell.
  • Remote HMI – Visualisation of the HMI in the browser to solve prob-lems together with the driver.
  • Remote software update – Update of system and firmware at the push of a button.
  • Remote monitoring – Continuous recording of relevant machine and process data. If required, also high-resolution data in the millisecond range.
  • Remote analysis – Analysis of recorded data during operation and without intervention in the machine control system. Faults can be detected at an early stage.
  • Remote control – Presetting of settings via web interface, without logging into the control system, protected by a secure user system.
  • Remote audit – All remote accesses and their actions are logged indelibly.

Testing & simulation

Switch cabinets with which your products/machines can be simulated or tested.

 

We manufacture customised switch cabinets for you.

 

Reproduce, test, improve

By setting up a test cabinet, hardware such as joysticks, displays, sensors, motors or complete machines can be simulated. Thus “components” can be used without having them on site. Using plug connections, power supply, inputs and outputs, and CAN communication between different hardware can be connected and checked quickly.

With this environment, it is possible to test products and code before they are delivered to the customer. This ensures consistent and high quality.

eBSS – Electro-hydraulic demand flow control

Energy-efficient, responsive, forward-looking

Development goals

The development of eBSS was carried out in cooperation with the Chair of Mobile Machinery.


The general idea behind the project was to optimise the working hydraulics of mobile machines, especially to increase of efficiency of a forestry crane hydraulic system. By minimising principle-related losses of a load-sensing control, the goal was to save energy by more than 10% by using an electro-hydraulic demand flow control (eBSS).

The following objectives were defined:

  • Reduction in fuel consumption
  • Minimisation of cooling power requirement
  • Reduced oil temperature » lifetime of organic oilsImproved cold start behaviour
  • Active influence on vibration susceptibility
  • Increased ease of use and productivity

Our contribution to the environment: energy savings > 10-20 % compared to load sensing systems

 

Functionality

The electro-hydraulic demand flow control (eBSS) is an innovative system to control pumps and valves in an open circuit. The system is suitableThe electro-hydraulic demand flow control (eBSS) is an innovative system to control pumps and valves in an open circuit. The system is suitablefor stationary and mobile applications.
The pump is controlled electronically and adjusted to the volumetric flow rate requirements of the valves. This results in very direct control of theconsumers and the energy consumption of the load sensing systems can be reduced noticeably.By controlling the pump without feedback, vibrations can be avoided and the reaction time is noticeably shorter compared to LS systems. For the driver, this increases operating comfort and the machine can be controlled more precisely and better.
