ECN Forum Forums Photo Discussion Forums Photos for General Discussion Loader Bucket Doesn't Reach

Notice the additional ears on the front bucket and the feet.. they look like they are designed to stradle the edge of the hopper to prevent sideways movement.

Wait for a hose, or some other component of the hydraulic system, to give out.

I don't believe it was designed to do this by the manufacturer (CAT).


Yes I see them and they look like items cobbled together by someone who thinks they are clever.

I doubt highly they where engineered or 'blessed' by Caterpillar.


Very true.

While hydraulics are often used in 'critical' applications any time a hose failure could be life threatening devices are welded to the hydraulic cylinder ports that will stop the flow if the hose breaks.

These devices can work by flow (two much flow will close a valve) or they can be 'cross' piped to the other port on the cylinder and require pressure from the pump to open them.

These devices can be seen on the cylinders of boom lifts, amusement rides etc.

You will not find them on the cylinders of the loader in the picture.

Finally I would really like to see him get it back down, getting up is often easer than getting down safely.

IMO this is a very stupid idea to try.

Iwire... 'Ya mean a " counterbalance" valve right?
A.D

Never herd of a counter balance valve.

Maybe we are talking about the same thing each in our local lingo?

I have worked with flow check and line lock valves.

The first would be used on a single acting cylinder and in the case of a hose break the valve would stop the 'leak' when the flow of fluid was to great.

The second was hard piped between the two ports of double acting cylinders and required the pressure from the pump to open up the valve and let the fluid out of the cylinder.

I've seen it done here. Couldn't believe it when I saw it.

The local sugarbeet factory unloads there lime cars that way.

Herzog Contracting Corp. has this "flying Bucket loader"for rent

Well looks like I eat crow here.

Follow the link above and you can see a video of this in action.

After watching the video I still feel it is a dangerous idea. Watch how when getting it down they actually pull the train out from under the loader.

A little to far and the loader will fall.

IMO this is simply putting an employee at risk for the benefit of saving money.

JMO, Bob.

Bob,

Please pass the ketchup.


I still don't like this idea, either.
I've seen some nasty things happen when equipment breaks.

cool video, one would have to be pretty sure of those joysticks to get that backhoe up there like that.
