The observant amongst you will have noted “V = I * R” on all our Department of CoRrections materials, but what does it mean? Well…
Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the three mathematical equations used to describe this relationship:
where I is the current through the conductor, V is the voltage measured across the conductor and R is the resistance of the conductor. More specifically, Ohm’s law states that the R in this relation is constant, independent of the current.
When designing electric sideloaders, Baumann always tried to give the priority to the performance of the truck. Whilst attempting to achieve the important requirement of additional battery longevity, we nevertheless considered the higher performance in terms of traveling speed, lifting speed, mast outreach speed, and other parameters that would make the machine comparable to a diesel truck of the same capacity.
It is a delicate balancing act between providing the right amount of performance but also having the capability of working a lot of hours and the result should be to reach the same level as the diesel truck.
To reach the target, we implemented 120-volt technology, using it for the first time on the sideloader. Ohm’s law was crucial to these developments. The 120-volt technology, combined with the optimization of many other parts of the truck, like the outreach system, hydraulic pump, electric drive motors and so on, enables the performance that we are looking for. That balance of productivity and longevity.
