  2. 1. Automation of Wheel-Loaders

    Author : Siddharth Dadhich; Ulf Bodin; Fredrik Sandin; Ulf Andersson; Jerker Delsing; Juha Röning; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Automation and tele-remote operation of mobile earth moving machines is desired for safety and productivity reasons. With tele-operation and automation, operators can avoid harsh ergonomic conditions and hazardous environments with poor air quality, and the productivity can in principle be improved by saving the time required to commute to and from work areas.

  4. 2. Vehicle dynamic analysis of wheel loaders with suspended axles

    Author : Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Abstract : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. READ MORE

  5. 3. Assisted Tele-Remote Control of Wheel Loaders in Underground Mining

    Author : Siddharth Dadhich; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Tele-remote operation of mobile earth-moving machines in underground mines supported byoperator assistance functions is attractive for safety and productivity reasons. This way, operatorscan avoid hazardous underground environments with poor air quality and the productivitycan, in principle, be improved by saving the time required to commute drivers to and fromthe operational areas.

  6. 4. Quantifying Operability of Working Machines

    Author : Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
    Keywords : Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. READ MORE

  7. 5. Optimal Predictive Control of Wheel Loader Transmissions

    Author : Tomas Nilsson; Jan Åslund; Lars Nielsen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The transmissions of present heavy wheel loaders are in general based on torque converters. The characteristics of this component suits these machines, especially in that it enables thrust from zero vehicle speed without risk of stalling the engine, without active control. READ MORE
