We’ve got an epic power struggle between 20 Toyota CJ40s all hooked together with towing ropes and a single Caterpillar D8 Bulldozer. The D8 Cat is an absolute workhorse. The two teams are connected via an I-Beam so that the Toyota’s can all pull together. An interesting concept that we will talk about later. As this unwinds, it shows the cat and Toyota’s getting into position. The D8 Dozer has no problem stopping all 20 of the Toyotas with just a gentle tap on the gas. However when push comes to shove, the team of 20 Toyota Landcruisers surprise the mighty D8 Cat Bulldozer. Keep reading to see how it all unfolds..
What We Are Actually Seeing
What we are seeing is the distribution of power in two directions. One direction fans out through the 4×4 Toyota’s in equal and straight lines. The other direction is from the D8 Dozer, and it is linked V-shaped cone from where its chains connect it to the I-Beam. Those power networks are not equal, and that has to do with how the base of power flows through each network. For the team of Toyota’s Landcruisers they pull in a pretty much even stream all along the I-Beam. Their base of power is the entire length of the I-Beam.
The Cat, on the other hand, has a much shorter base of power, and it can only counter the power from the Toyota’s from the center of the I-Beam. That base of power is weaker, even though the Cat is likely more powerful.
Problems Two and Three for the Cat D8
The second problem for the cat is that each of the Toyota’s has four tires on the ground. That is eighty points of contact and traction against two tracks. The Toyota’s have the advantage.
The third problem for the Cat is the way that they have it chained to the I-Beam. It is chained to the front dozer blade, and as the tug of war begins, the power from the Toyota’s overcomes not the cat, but the hydraulic system of the blade. You can see the blade begin to rise and that moves the center of gravity from a horizontal surface towards the rear portion of the tracks. When that happens, the Cat loses traction and is pulled backwards.
The Simple Fix:
Readjust the connection of the Cat to the I-Beam and try it again. It would be interesting to see if the Toyota’s could move the cat if all of the Cat’s traction were in place. Another potential fix would be to line all twenty Toyota’s up in two lines so that the pulling ration between both forces along the I-Beam would be in an equal ratio. In so doing, the results of this massive tug of war might be quite a bit different.
Caterpillar D8 Bulldozer Stats:
- Horsepower Ranges from 235 in 1958 to 335 in 1982 and back down to 310 in 2004.
- Total Weight is +/- 80,000 pounds
- Width 101 inches
- Length 186 inches
What do you guys think? If they changed the way the Cat was connected to the I-Beam, would the outcome would have been different? What do you think the outcome would be if the area were hosed down? Do you think that the Cat could win this tug of war?
