Has anyone come across an off the shelf type hydraulic levelling 4 leg system that can be fitted to a shipping container and level it out. I am talking of something that will bolt on and be able to lift a container about 300mm and be able to adjust each leg individually so to adapt to the ground its placed on.

I have searched all over the net and not come up with anything other than trailer landing type legs(Manual) and systems for Motorhomes only. It must be able to lift and level a fully loaded 20ft container.

A self contained type system would be preferable even if the power source is either battery or external hydraulic power.

I did find a manual system in Denmark for astronomical money for four legs.

the only thing i can think of is if you use the jack legs off the back of a jcb and make brakets for it to fit on the container and power it off a hydraulic power pack or a digger ect

Taurus me ole mate one of in your threads you was saying work was quiet:( so why not make some:) four rams, bit of box section few meters of pipe and a tail lift pump/motor of a truck sorted:D

Well, there in is the idea for why i asked if anyone else has seen or heard of an off the shelf system. I am busy coming with my own design for a set. It does take a bit of brain cell bashing as i want it all to be fitted inside a
6" x 4" box section if i can.

It is for a project so can't be made with second hand bits and cobbled together.

It has to look the dogs bollocks and work spot on as it also has to be certified fit for use.

If you can work out a way to make a set that could jack a container off a lorry I'm sure alot would be most intrested.

You've just solved my problem of removing shipping containers without a expensive crane....

I think on that sort of lift would be interesting, it would have to be stable enough but the disadvantage is the weight and ram would have to have a stroke of at least 1600mm .. To be able to lift it and then lower it to the ground from deck height..

i am no spanner man but could it work with a ratchet system type thing. keeping the ram short you could have the jacks but as you push down near the end of the ram stroke a spring loaded togle type thing would drop into a hole or slot. this would hold the weight while you take another bite and so on till at desised height. just my thoughts. mr mogman or leaky are the men.

Not sure if this is the simplest route, one container and about 10 men to set it up, and take it down... hmmmm

Came up with this Tuarus
12524
If you use 3" rams at 3,500 psi it will lift 11.2 tonnes so x4 = 44 tonnes put the rams in box section which will slid into another box section weld the outside box to a piece of 6" angle that will go around the corner of the container with a strong lug welded to the inside to locate with the lower twist lock side holes:D

sorry no CAD here:eek:

Nice idea Mogman, How would you lock the leg to the corner block of the container? As the ram rod would be in the way. Unless you lock it from the alternate side if you know what i mean.
However having a locating pin/lug on the ram side to stop it dislodging when the rams are activated.
My idea is to incorporate the Hydraulic pump, motor and tank,Ram and valves and switches into the post as well so its all in one. Using a 6" x 4" box section as the body.

My minds working now (unusually) We have some nice skiplorry rams with enough stroke and power to remove a empty container, And it will only be on our site so moving them rounds not a problem (forks).

How would you lock the leg to the corner block of the container?

By having a lug (a bit like the ones on the side of a skip) on the inside of the angle iron, the angle iron will be a snug fit around the corner of the container so will not come off
as for pump controls etc on each ram would that be a bit eer big:(

as for rams how about some legs from a hiab will have check valves in the top and be certified:D

Well, therein lies a secret.. i have access to a rather nice pump and motor setup that fits in a small space switches direction of oil flow electrically, check valves can be fitted directly to ram porting by special banjo fittings.. I am going to look at building a prototype in the next few weeks..And hopefully start advertising it online in the next month or so...

I would put the ram inside a cylinder or box section withy a pin passing through the top and through the cylinder rather like a jack leg. A lug as described by Paul would then be welded to the side of the box. How will you control each leg because the one with the least resistance will travel until it hits more resistance than another of the rams. If each leg has it's own valve you will have a mile of hoses. I deal in containers and metal boxes and i must say we position them with the lorry crane or excavator. The containers don't have jack legs so they have to packed up from the start. How will you lift all this gear and how long will it take to set up ? We use a bottle jack and toe lifter.

The idea Trax is sort of along those lines. But with a small hydraulic pump unit and tank in each leg and a up/down switch unit fitted.. All you would have to do is add a power source. ie 12v . The units are more for a permenant fixture for high end specialised generator / electrical / computer type units.
You could still use a crane / helicopter to locate the unit generally then use the hydraulic legs for levelling expecially in uneven terrain and remote locations.
I have recently quoted on a large project for 96 of these type legs.

And having been quoted by a Danish military supplier for four manual legs at 18 800 and a twelve week delivery.. I did not feel so bad with my quote being just over half that.

I see, Well i have a better idea. Position the legs inside the box, in each corner. i have plenty of ideas but you say you have already priced them , so what is your design...?

Taurus66

A 6" x 6" box section ram fitted internally like you said. Pump/motor/tank slides down inside just above the ram. Ram secure by pin similar to your idea. Mounted with a 10 bolt flange with a corresponding flange plate already welded onto each corner post of the container.

My original design was to have a single 240v pumping unit under floor inside the container, 4 lever valve on the wall inside. Stainless steel tubing under floor in channels to the end floor plates, feeding the legs with flexible hoses.

But new ideas keep coming into my head.. new options for power sources, ie tractor hydraulics/ beaver pack hydraulic pack/ 12v/ 24v/ 110v/ 240v/ 415v and finally double acting hand pump..

I did think about having the legs inside the corner posts.. A great idea but it will weaken the design as the corner posts are designed to take 276 000lbs of load being stacked 8 high with out collapse.
If you then cut into that you take away the design strength. But it would be great to have it entirely hidden from view.

I also looked into having the whole system remotely operated from a hand held controller.. But that got into silly money..

You could fit a new section of box into the corners using thicker section material with an access covered by an equally thick plate bolted with enough bolts to ensure the strength.

What do you do about the lower corner blocks? As they are a pretty much an integral part of the structure. Hence why i think it better to have the legs on the outside , there by not interfering with the main load bearing corner posts.
However saying that.. there are many ways to skin
the proverbial cat..

The ram rod comes down through the twist lock hole. On first positioning of the box you place a plate with rod locator down and when the rod extends it mates with the plate a safety pin could also be used to lock the rod to the plate by passing through the locating collar.

what about this one trax. when a container goes out on trailor could they pump the air bags to max to lift trailor, put jack legs under corners and let air down. dont know if this is possible as not been near an arrtic for years.

Trouble is Dj shipping containers don't have legs so you'd have to fit adjustable legs too..... then you would have to get the unit to the ground from the trailer hieght.

The only problem that i can see with fitting the lifting legs inside the corner posts is that then you can no longer use the container locks on a trailer to hold the boxes down for road transport.
We bought a pack to build a container from scratch and had a look at various options, and it seems to be the best place is just inboard of the existing corner posts on the out side.
Just building 12v hydraulic pumps for a version which all you need to do is plug it into a battery pack, switch it on and press a button for up or down.
Monday we start building our container .. should be fun...

The ram rods would lift up enough for the twist locks to still work. Just a plain ended rod that came down through the twist lock cavity. the top of the cavity would have a hole just a fraction larger than the rod diameter.

I understand what your saying, but will be a bit difficult whan you have a foot to be attached to the rod end eye. These are to be landed on soft sand so need to have a foot of at least 6" square and then land on top of a pad 18" square to stop the 16 tonnes sinking in.
The idea is ti have each leg indendant so that whan level you can lift on leg and insert the pad and lift up, going round all four legs before final levelling.
I did consider using an electronic self system but the sheer costs went through the roof.

The box wouldn't need the twist locks prior to lifting down to the ground. You operate the jack mechanism in order that the plates fitted with a boss type locator and pin could be fitted to the rods as they protruded from the underside of the corners. Use a low flow valve bank that can be quick coupled to the jack hoses. once positioned the control valve can then be detached to be used on the next unit.
