Leaving Implements Raised - Bad For Hydraulic System?

[oosik]

The hydraulic pressure will slowly bleed off and the implements will lower to the ground because of that. That's what I thought would happen. After a month with my implements( FEL & 3-point) raised and having not dropped even an inch - I manually lowered them for safety's sake.

There is nothing in the components that will be a problem. Seals are contained so that they can easily take the pressure created by various use which is significantly more than when stationary. The only issue I have see is that when cylinders are extended the rod can corrode or collect contamination which can get in the seals and cause leaks. Not a problem short term but it depends on how long they are left in that condition.

Again, do backhoe cylinders made of special metal or last less longer than their FEL counterparts? Dipper and bucket cylinders are left exposed when 'at rest'.

Backhoe cylinders are no different than any of the cylinders used in FEL or Grapples. You simply scale the cylinder for the amount of work required. Cylinder corrosion and seal breakdown on a parked backhoe is a concern, if it's been parked for many years exposed to the weather.

 

[rademamj1]

You cannot park any backhoe without extending some of the cylinders. The right and left stabilizer arms must be extended to park the backhoe.

Hence why the fuss about the FEL cylinders being exposed if there is no other ways for backhoes and IF they last as long as FEL cylinders.

If you own a hydraulic device that corrodes the cylinder ram from sitting you may want to consider selling such device because you certainly don't need it.....

Not everyone lives in areas with the same risk factors. Near the ocean there is high salt content in the air, arid climates have high levels of fine grit in the air. Every time you retract the cylinder after being extended for periods of time in these conditions exposes the scraper rings to contaminants. Eventually they are worn and become less effective and the contaminants then attack the seals. Material that gets imbedded in the seal pack then runs up and down the rod leaving scrapes, bad enough and the seal can no longer contain the oil in the damaged section of rod.

The argument around the backhoe is ridiculous, I'm sorry. Just because we can't take all precautions with one device, we through all caution to the wind? Cylinder rod exposure is a factor, area of operation will dictate how much. In the marine industry you will be hard pressed to find vessel equipment designed for the exterior that doesn't have all cylinders retracted when in the parked position. Working in the offshore subsea construction industry our box section, knuckle boom cranes are why the ship is hired. It might need to be in the air for hour, days, weeks on end to suite the client's needs. If there is even an hour break in activity it gets parked.

Tools are like relationships, love them and they will love you back.

So how long does it take to ruin an exposed cylinder ram? Ballpark guess?

Looks like you missed the uppercase IF I wrote, because IF backhoe cylinders last as long as FEL, why does it matter? Of course, if they last less, then it totally make sense.
