Bendpak XPR10

[HAP]

Posted a few pic's of my lift install last month. Got some questions about height to overhead bar clearence. My '06 Navigator is the longest/tallest vehicle that I have had on it. The front of the cab has plenty of room under the bar. I also erroneously reported that my retrofitted wieght gauge read low. I confused the GVW to Curb Weight. It does in fact read correctly as I compared the advertized Curb Weight (5,555 lbs) of the '06 Navigator to the guage and as you can see it is pretty accurate.

how you do the gauge deal?

how you do the gauge deal?

I ordered it from Mohawk. They had a lot of questions as to why I was ordering the gauge... it's offered on thier website.

You can try to order one direct from LENZ, but they appear to have a minimum order requirement. It would not have the Mohawk logo...
I studied the pump housing and by logic figured this to be the correct port to intall the gauge.

Hey can you tell us the details (Which gauge, which port, and cost)
I reallly like that option.

I am also interested. Looks like you got the 7k model even tho your lift is good for 10?

 

[Ign]

Also everything I see on the Lenz site is a pressure gauge? Looks like Mohawk has figured pressure to weight and made their own custom face?

If you look closer you can see that it is labeled for the 7K and System 1A which is the Mohawk 10K lift. That is why the guage is marked in both red and green in the 7-10K range. Ill post the Mohawk guage link later...

I wish they would list prices - even "suggested retail" prices would be helpful. I get tired of having to fill out forms and wait to be contacted just to get a price on something. I just went through that while shopping for garage management software. It does look like something I'd like to add on to my XPR.

I had a website that listed all of Mohawk's accessories and prices, can't find it... Anyway, the gauge lists for $125.00 for all size Mohawk lifts. They are the only place to get them from. LENZ is the OEM for Mohawk.

Looks to me like this is exactly what they did, and then marked up the price a ton. You can get high pressure gauges just like that for under $10 from surplus center, which is probably what I'm gonna do. Then you just have to calibrate it to figure out what the corresponding PSI/Weight is and simply draw the markings on yourself.

Anyone know the max pressure the lift hydraulics will see? Also for the OP, do you know what type of fitting that is in the power unit? Is it an o-ring fitting? NPT? other?

 

[c39er]

I think BP ought to offer these guages. They would be a great accessory probably many folks would want custom accessories! I make my own but cannot make a nice complimenting guage. I'm sure it wouldn't be as pricey as the $$$$Mohawk stuff. It would be nice if BP could do a custom BP face to match the lifts too.
How bout it Jeff?

 

[mslisaj]

Count me in Jeff. It would look good on my XPR10-ACX.
Please let us know when we can buy this accessory.

SB it is an "O" ring connection. If you know the factory curb weight of any vehicle, you can just use that as your calibration weight.

[mslisaj]

Well yes, we could do that. But personally I'd be willing to pay a premium price to Bendpak to have them do the calculations and put their logo on it. So I'll wait for the custom gauge.

[my58]

Since the Danmar lifts use the same motor and pump the Danmar owners would purchase these also!

I find it funny how few lift accessories are available. I would think Danmar would offer custom nobs to put on the release lever. I am thinking of milling an adapter from the thread on the lever to a shift knob lever. A cool old school skull seems appropriate to me. I made fire extinqusher mounts and a bunch of other stuff for my lift, I would have gladly payed someone if they sold them. I am sure I am not the only one that wants to customize my lift.

We need to start a Lift Customization thread!

I would like to put one on my 9K Rotory Lift. Tell me if this sound right. I would way a vehicle and then install the gauge lift the arm un loaded and see the pressure on the gauge. then put the car on the lift subtract the pr. of the arms from the total pressure. lets just say the arms are showing 500psi the car weighs 2000 lbs. and the gauge when lifted is 4500psi subtract the 500psi and the we have 4000psi for a 2000lb. car then we have 1/2 psi per lb. after subtracting the psi for the lift arms. am I on the right tract.

You would "weigh" a vehicle.

I would think we should NOT subtract the weight of the runways. If a lift is rated at max 7000 pounds for example wouldn't the weight of the runways be included. I imagine we would like to know by looking at the gauge how close to maxing out the lift we are, that is more valuable then car weight. I am only guessing but I think the gauge should show total burdon on system.

At least that is what seems to make sence to me... (sure don't make it right)

Hap, Thanks for the info. It helps me understand this better.

I was not arguing the point of how the Mohawk is calibrated and their gauge clearly states vehicle weight. My comment and thoughts was that if I / we were to calibrate a gauge it would seem to be more valuable to know how close to the X pounds limit we are reaching.

Now if you are saying that you believe a lift rated at 7000 pounds is strictly talking about vehicle weight and has nothing to do with "overhead of unit" then it makes sence why Mohawk only shows vehicle weight.

Thanks again for the info.

Maybe one of the lift vendors can tell us if the ratings of a lift are calculated based on strictly vehicle weight.

The right way to calibrate it is to actually weigh a vehicle at a certified truck scale. Advertised curb weights are often quite far off and dont account for optional accessories, fuel loads, etc. Just filling the tank on my truck changes it's weight by over 250lbs.

As for the question of subtracting the weight of the arms, I believe the rated weight is how much weight the lift can actually LIFT. Seems kinda backwards for someone to have to figure out how much the moving parts of the lift weigh and subtract it from everything they put on it. If my lift says it has a 10k capacity I better damn well be able to lift a 10,000lb truck.

I looked at the pump on my lift and it has a "relief pressure" of 2600psi, so I ordered 2 different gauges from surplus center so I can figure out what the actual pressure range is. Total cost with shipping was $23.10

Having a custom face with a brand name is nice and all, but having an extra $100 in my pocket seems a lot more useful to me.

 

[my58]

StinkBug,

What gauges did you order? Please keep us posted on your outcome, many of us can learn from your experience.

Thanks!

Maybe. They probably figure the weight of the arms is insignificant when viewed in the face of 10k lbs total, and easily absorbed by whatever safety factor they believe is built in.

It might just be based on cylinder capability like trailers are based on GAWR. You can't actually put 7k lbs payload on a trailer with two 3500lb axles unless your frame and deck are built of air (common incidents of overloading aside).

 

[StinkBug]

That's an apples to oranges comparison though, as trailers are rated by their GVW (gross vehicle weight) whereas lifts are rated by their lifting capacity. One specifically includes the weight of the vehicle itself while the other implies actual carrying capacity.

I dont remember the actual model #s of the gauges I ordered, but both have a 1/4" NPT fitting on them. One is 2000psi, the other is 1000. I'm going to mount up the high pressure one first and test it to see what the actual pressure range is. If it's lower than 1000psi then I'll swap gauges, otherwise I'll use the second gauge for a different project. The gauges themselves were only $5 and change so I dont really care if one doesn't get used. Even buying 2 I paid as much to ship them as the parts cost.

 

[StinkBug]

Ok here's what I did on my bend pak MX10CX. Could have been cheaper but my local fitting place didn't have everything in stock so I had to combine some pieces to make it all work. I had to use 3 fittings to adapt the gauge to the pumps extra pressure port, but I've seen the adapter to do it with one. All you need is an adapter that goes from -6 O-Ring to 1/4"NPT Female. Here's what I used.

21-1605-DA 2000PSI Pressure gauge from Surplus Center $5.95

980006 XRP -6 Male Flare to -6 O-Ring Boss $6.70
916106ERL Earls Straight -6 Female to 1/4" NPT adapter $8.63
991602ERL Earls 1/4" NPT 90 Degree Female union $16.80

Total cost $38.08

I could have saved about $10 by using a straight union instead of a 90, but I liked that it would put the gauge straight up and right next to the pump motor. If I were to do it again now that I know the fitting sizes I'd simply order the gauge and this fitting from surplus center and be done. The total cost with shipping would be under $20

Item# 9-6900-6-4 SAE 6M x 1/4 NPTF SWIVEL $2.05


Regardless it works just fine. Looks like the weight of just the arms alone takes about 100psi to lift. I also picked up my Crew cab diesel Chevy 2500 which is the heaviest thing I own at around 9klbs and it sits at right around 1150psi. While lifting the gauge reads about 1600 so I think the 2000lb gauge will work nicely. Once I actually go weigh my truck I'll do the calculations on what weights the gauge readings correspond to.

 

[HAP]

SB, thanks for taking the time to share your MOD/adaptation with us. I really thought the pressure readings would have been a bit higher. I feel that most lift manufactures have missed the boat on offering this option; especially after you post your cetified weight-pressure comparisons. Most will simply follow your lead and make their own weight guages... of course, your calibrations will apply only for lifts with the same dia cyl's.

HAP

Are those ramps the ones that came with your lift? Mine are flat with sand finish. I like yours much better...

Well, well well, I take off a few days to Costa Rica for a 50th-bday adventure celebration with some high school buddies and find this. Uh…..pretty cool. I like.

I'm familiar with the Mohawk gauge and was somewhat skeptical about the marketability, but if you guys think a good idea, I’ll be happy to throw it on the project board. Strange how it seems to be already calibrated for our hydraulic cylinder size and pressure in its current configuration.

I’ll keep this moving and get back to all when the development materializes.

Now back to the pool…and canopy zip lines, and white water rafting, and ATV riding, and horseback riding, and… a whole lot of ”refreshments”.

Cheers.

Ok I just got a chance to actually weigh my truck, and no big surprise the actual weight was MUCH different than the claimed curb weight.

From a quick Google search it looks like the published curb weight for my truck is 5972lbs. The actual weight with 1/4 tank of fuel and no occupants was 6800. Yep, that's right, over 800lb difference. Still less than I thought, but I was just pulling numbers out of air before today.

Anyways, if we know that it takes 1150psi to hold the truck up, and subtract the 100psi it takes to hold the lift itself up (with no load) that means every PSI on the gauge equals 6.4762lbs. or each 50lb increment on the gauge is good for 323.81lbs. Of course, I'm still considering this a rough estimate until I weigh another vehicle and do the math again with both weights.

I find it very interesting this thread comes to life again 2 years after this discussion was started. I gave Jeff at Bendpak a thumbs up on a "factory accessory" back in March of 2012. Then I noticed that Jeff in April of 2012 was going to "throw it on the project table" but nothing has happened. Maybe there is liability issues for Bendpak to make a gauge like this or some other reasons. I applaud the guys that have done it on their own and the cost of the "accessory" has not stopped them from making one but I personally am still waiting for Bendpak to do a factory gauge. I still have money in hand Jeff and it would great on my XPR10-ACX.

Thanks guys for your ideas on making your own. I may eventually go that way too.

Regards to all.......
