I'm jest a natcherly LAYZEE 'B'.
Hi, Steve.
I was visualising the finger lever steering that Cat's D10 and D11 'R' series machines now have around 25 years ago and thinking to myself how easy and simple it would be. I have to admit though that they bettered my thoughts with their trans control arrangement.
I learned to run excavators (See how lazy I am? 'Run' 'cos I'm 2 tired to type 'operate'.) on the old 'four-stick' (Ackshully 2 stick n 2 pedal.) Hitachis and Katos. Then I came across a JCB 6D and a Hymac 580C, both 'joystick' machines (of sorts) but with incredibly different layouts. The JCB was closer to what we know today but the DIPSTICK who designed it couldn't even get the single functions on each stick right. To use a single function on either lever, you had to move the stick diagonally, not sideways or up or down.
Now the Hymac 580c was a different beast altogether. The swing function was controlled by 2 pedals on the floor. They were on a rocker arrangement so that when one went down the other came up. Press the left one to slew left, press the right one to slew right. Great stuff. I had used almost that exact set-up in a Marion 191M diesel-electric face shovel around 10 years before.
Next, you had 2 great long joysticks coming up from the floor. Pull the right back or push it forward and the boom went up or down. Pull the left to you or push it away and the dipper went in or out. Great. Works just like you'd expect it to. So far, so good. Then if you pushed or pulled the right lever sideways, the bucket opened or closed. Again, about what you'd expect.
Then they had throw in this gem. Moving the LEFT lever sideways operated the second stage hoist function, raising or lowering the boom quicker. I always thought it would have made more sense to have first and second stage boom hoist on the SAME lever.
And both the JCB and the Hymac had one of the dumbest arrangements for travel controls that I have ever seen. The levers were down beside the seat and moved backwards and forwards. So far, so good. BUT, they clicked into position. Nice when you were walking from one spot to another but abominably STUPID when you wanted to do something fiddly, like load it onto a float. More often than not, when trying for neutral, you pulled them straight through into the other direction. And they were almost impossible to 'feather' as you need to be able to do when performing fiddly operations.
Then there was the International 3980 by Yumbo of France. It had an 'almost joystick' set-up. Hoist fore and aft on the right stick, dipper fore and aft on the left stick. Pretty normal so far. BUT, to slew right, you pulled the LEFT stick toward you and to slew left, you pulled the RIGHT stick toward you. And what of opening and closing the bucket, you ask? Well, that was two pedals on the floor under your right foot - and you had to change pedals to change from opening to closing or vice versa.
Let's leave Stupidity Corner there. I'm too tired to type any more. LOL.
