How about Cape excavator

  • drives failing to achieve maximum force · Issue #452

    It turns out that the reported velocity is close enough to the target that there is insufficient force to lift the machine. However the reported velocity is not accurate when compared to the actual change in position. i.e. if I use getVelocityAtPos to get the velocity at the two end points of the distance drive and compare to the actual rate of

  • Definition of Tractor Loader Breakout force - Kubota

    Liming 118274. Breakout force is the force available to lift the FEL at the bottom of the pile for example with the cylinders fully retracted. For example an articulated wheeled loader may have a breakout force that exceeds the rear weight of the loader. When you apply the lift or curl the back end can lift before the material falls off or

  • How Caterpillar Backhoe Loaders Work - HowStuffWorks

    The boom arm is connected to the tractor with a swing casting so that these pistons can swing the backhoe arm from side to side. They are synchronized so that when you push with one, the other pulls. In many European backhoes, the boom is attached to a side-shift mechanism, a bracket that can move the entire backhoe arm horizontally on the tractor.
