Plant, Equipment & Site Operations process in which feedback from the field can directly influence the finished machine.
“ Feedback becomes valuable when it changes a design decision,” Durand shares.“ The operator may never see the engineering discussion behind that change, but they will feel the difference every time they use the machine.”
From capability to usability The same principle takes on a different form at the smallest end of the excavator market, where the machines often work where access is part of the challenge. Renovation projects may require equipment to pass through an existing building, while urban infrastructure work can leave little room to maneuver.
At 740 mm wide, the SV10 can pass through a standard doorway, before expanding its undercarriage to 990 mm once in position. It is a design shaped around the sequence of the task: negotiate restricted access first, then establish a firmer stance for digging. Its layout also reflects the realities of rental fleets, where machines move between users and need to be put to work quickly.
Repositioned side levers create more operating space, while the controls are arranged to make familiarization straightforward. A tilting engine hood provides direct access for daily checks.“ For contractors and fleet owners, usability affects how quickly a machine can begin work and how consistently it earns its place on site,” confirms Durand.
When the machine begins to assist As machines take a more active role in the work, the relationship between assistance and understanding becomes increasingly important. Often, the most successful intervention is one that asks almost nothing extra of the operator. Yanmar’ s Safety Joystick, for example, activates the controls only when the operator intends to use the machine. Accidental contact does not activate the equipment, while the controls lock when the operator leaves the seat.
Built into a familiar movement, the protection adds no display or sequence for the operator to manage.“ New technologies create opportunities, but they also introduce complexity,” Durand says.“ The priority is to ensure that complexity does not sit with the operator.”
Active Tip-over Mitigation gives the machine a more direct role in managing risk. By assessing how the payload interacts with the machine’ s posture on sloping ground, the system can limit certain commands as tipping risk increases.
Technology with a lighter touch Some practical engineering questions begin far from an ordinary jobsite. Yanmar’ s Force Control research grew partly from the challenge of future construction on the Moon, where communication delays mean machinery must respond to changing terrain without constant direction from Earth.
Working with JAXA’ s Space Exploration Innovation Hub Center, Yanmar tested a force-controlled robotic arm on a lunar-rover research model, including travel over soft ground and excavation. The principle was then applied to an electric prototype based on the ViO25 mini excavator, using a Series Elastic Actuator to sense and regulate applied force.
Development is continuing, with Yanmar now supporting field testing with customers on real jobsites to understand where the technology can bring the greatest practical advantage. With that work still in progress, further details remain under wraps for now.
“ Force Control will help make heavy lifting and handling safer and easier by precisely sensing and controlling applied force,” says Durand.“ The aim is to reduce physical strain and improve productivity, allowing work that once required several people to be completed more efficiently by a smaller team.”
Progress that can be felt Yanmar frames this approach through two design ideas:“ Intrinsic Design” begins with the purpose the machine must serve.“ Gentleness & Toughness” brings the resilience required on site together with greater consideration for the person relying on it. Progress is judged by whether the engineering solves a real problem, in real conditions.
“ Technologies will continue to evolve, but our measure of progress should remain practical,” concludes Durand.“ A development has value when people can use it with confidence, in the environments for which it was designed.”
Perhaps the most successful engineering eventually recedes into the task itself. Its assistance arrives without interrupting concentration, while the sophistication within the machine is felt through work that becomes steadier in the operator’ s hands.
