We’re getting into the spring season, the place we obtain lots of calls from consumers inquiring about hydraulic put up pounders for his or her skid steer or mini excavator.
Lots of our consumers start by way of asking: How do hydraulic put up pounders paintings? What does “power magnificence” imply when evaluating put up pounders? And what sort of repairs is there?
On this article, I’m going to respond to your whole questions, and if you wish to know extra on the finish, simply give me a choice!
Key Takeaways
– Vibratory hydraulic put up pounders use your skid steer or excavator’s auxiliary hydraulic fluid to push a piston upwards towards a nitrogen chamber.
– When the piston is within the peak place, a mechanical valve releases the hydraulic drive, permitting the nitrogen fee to power the piston down.
– A put up pounder’s power magnificence is a measure of the power it exerts with each and every blow, expressed in foot-pounds.
– Maximum put up pounder repairs is restricted to common greasing and an annual nitrogen top-up.
What’s Taking place Inside of a Submit Pounder?
Vibratory hydraulic put up pounders use hydraulic fluid out of your skid steer or excavator’s auxiliary hydraulic line together with nitrogen again drive to create the hammering motion on an inside piston.
The inner piston moves your put up motive force software, which transfers power for your fence put up.
Hydraulic Power VS Nitrogen Power
Hydraulic fluid is non-compressible, whilst nitrogen gasoline is. Subsequently, the put up pounder makes use of hydraulic fluid to boost the piston and nitrogen gasoline to hammer it back off.
Hydraulic fluid is shipped out of your skid steer or excavator for your put up pounder via your auxiliary hydraulic pump and hydraulic strains.
When the piston is on the backside of its stroke, an inside mechanical valve directs hydraulic fluid right into a chamber that may lift the piston.
As soon as the interior piston reaches the highest of its stroke, it’s pushing towards a chamber stuffed with nitrogen gasoline. The drive towards the nitrogen chamber is what will create the super downforce as soon as the hydraulic drive is launched.
With the piston on the peak of its stroke, forcing itself towards a nitrogen chamber, the mechanical keep watch over valve releases the hydraulic drive, and the piston is slammed down.
A Be aware Referring to Nitrogen
It comes up in dialog from time to time that there are other folks available in the market who suppose nitrogen is utilized in put up pounders handiest as a result of it’s readily to be had at maximum welding retail outlets. This isn’t the case!
Nitrogen gasoline is used for again drive as a result of it’s non-flammable, inert, and strong. Striking another gasoline, together with compressed air, into the nitrogen chamber will also be very unhealthy – so don’t do it.
Different Submit Pounder Elements
Vibratory hydraulic put up pounders even have an inside accumulator. Throughout the put up pounder, hydraulic fluid is continuously biking between excessive drive and no drive and due to this fact wishes a way to hose down the interior hydraulic forces.
The hydraulic accumulator is a small bladder that applies a small quantity of drive towards the common circulation of the hydraulic machine. When there’s a unexpected building up in drive, the accumulator will fill with hydraulic fluid and soak up the surprise.
For the reason that accumulator is fairly pressurized, when there’s a unexpected lower in hydraulic drive, the accumulator will push fluid again into the hydraulic machine, dampening the lack of drive.
What Does “Power Magnificence” Imply for Submit Drivers?
Power magnificence refers to what number of foot-pounds of power your vibratory put up pounder is making use of. It’s a very simple manner of evaluating the power of 1 put up pounder towards some other.
For instance, a Montana 750R put up pounder has an power magnificence of 750. Which means this put up pounder will practice 750 foot-pounds of power on each and every blow. Whilst you imagine that it’s offering 500 to 900 blows consistent with minute, it is a ton of power.
*Foot-pounds of power are outlined as the volume of power had to transfer an object one foot. So within the above instance, the Montana 750R can transfer a 750-pound object one foot on each and every stroke.
What Repairs is Wanted for Hydraulic Submit Pounders?
With only a few exceptions, the hydraulic put up pounder is likely one of the best possible attachments to take care of.
Except for making sure that each one hoses and connections are tight, there are handiest two common repairs pieces wanted.
Greasing
Submit pounders create a large number of warmth when they’re working, and due to this fact they require common greasing to assist with cooling and lubrication.
You’ll discover a grease zerk situated at the primary frame of the attachment, which can feed grease internally. Apply the producer’s directions on the kind of grease and frequency of greasing.
The usage of unsuitable grease might purpose the grease to warmth up and run down the ground of the software. For those who realize this, forestall pounding instantly and examine the purpose.
Nitrogen Filling
Ultimately, you’ll need to fill up the nitrogen fee in your vibratory put up pounder.
Producers would possibly not supply a advisable refilling period.
For those who start to realize that your put up motive force doesn’t have the similar energy because it used to, it could be time to recharge your nitrogen.
For those who suspect your nitrogen is low, you’ll be able to purchase a recharge equipment out of your broker. It’s essential to notice that the nitrogen bottle will arrive empty as it’s unlawful to send complete bottles in the US.
You’ll fill your empty nitrogen bottle at a welding store after which simply fill your put up pounder when your again on the store.
Conclusion
Vibratory hydraulic put up pounders are easy hydraulic attachments that don’t require electric hookup or high-flow hydraulics.
The straightforward hydraulic working ideas handiest require as low as 8 gallons of hydraulic circulation consistent with minute, making this attachment usable on just about any skid steer or excavator.
With handiest easy greasing each and every few hours, you’ll have the ability to pound posts like a professional.
