How many lifting jacks are typically used raising a loco ?

Postby 0121modeller » Tue Oct 26, 2010 4:54 pm

As the title question states, how many loco jacks are used ?
I would imagine 4 jacks is the obvious answer, but are there exceptions where more either side of loco would be used for heavier loco's or major chassis work ?

& also where would the typical jacking points be ? ... (as on a motor vehicle there are certain "safe locations" for lifting) , I'm thinking of a class 47 in particular, as I believe the side panels play a major part as to keep the body rigid rather than the chassis doing so.

Many thanks for replies, Any photo's or links greatly appreciated :D ,
Dave.

Hi Dave,

The images below show a Irishrail 2600 series 2/car railcar set up on the jacks. A total of 4 jacks to hoist the railcar up in the air. If the bogies need to be removed, then there are 4 more jacks, 2 to each bogie that will rise along with the 4 lifting jacks so as to lower the bogies to the ground leaving the railcar body in the air. See photos below I made at Drogheda Railcar Centre.

I guess the same or similar arrangement would also be used to lift and remove a locomotive bogie etc.

Cheers for that photo Ian :) , It looks like in this instance more than 2 jacks were used either side of that class 50.

(I always knew your class 50 photo's would be of interest in one way or another !! :wink: ) Cheers Ian :D

Thanks also Wilson (K9-70) , those photo's etc are also helpfull & very much appreciated for a long awaited modelling project I have in mind.

Cheers Chaps :D

i've seen Deltics with 4 on each side (total 8 )
funny that. because logic makes you think 4 would be enough really

Cheers Bobby, I would agree & thought that may have been the case quite often.

The type of jacks I'm looking for is not so much the fixed installed type as seen in the loco sheds (although photo's already kindly posted are a good & useful referance as they give a viual insight to jacking point area's , written info/desciption given etc) .., I was thinking more of the "outside depot / yard area sort of portable jacks, as I've recently purchased some Bachmann loco jacks & have 2 more packs (4 in each pack) on thier way to me from Hattons..,

I have a photo of my own that I took about 10 years ago of a class 40 , the jacks used look rather differant to the winding screw type jacks from Bachmann,
The jacks seen here look more like large pyramid style axle stands for my car ..., I'd always wondered who I'd borrowed mine out to & never recieved back ! :lol: ;
The photo quality is too poor to give a clue whats holding the other end up , but it looks like a stack of wooden pallets is obscuring the view of other end.

Ian ., if you have more pic's with 50's / Royal Oak, or whatever else you have (jacked up), then please do post them up :D

I have decided to re-generate a major part of my current layout, the current station has no space as to "move trains" & so it'll make way for an area/yard sidings for "stored servicable" & dilapidated locos, a couple of wagons & a class 108 DMU..., plan is to have a couple of loco's on axle stands / up on loco jacks.
I've come to this decision as lack of space restricts much train/stock movement, apart from 3 engines taking it in turn pacing back & forth on thier own.

Any other photos with loco's jacked up/on axle stands, especially featuring designated jacking points greatly appreciated as for referance purposes for modelling such scenes.

Thanks for all help on this so far chaps :) ,
Dave.

During a visit to Glasgow Works many years ago, just about everything was lifted by a set of 4 jacks, typically one at each corner
This included a Class 37, a Class 47, a Class 314 EMU vehicle, and a Mark 2 coach

To me that picture looks like 2 jacks on each side and a couple of spares not in use. Can't see why you would need more than 4 for most jobs.

There are a couple of different types in use but the 'fixed' ones generally in use now aren't fixed at all, they can be repositioned to accommodate different length vehicles. The Bachmann ones are a pretty good representation of these. I'm not aware of any depots currently using this type outside but that doesn't mean there aren't any, and of course what BR did in earlier years may be different.

DMU/EMUs - typically one at each corner of each vehicle, the set at Neville Hill can lift a 4-car 333 set in one lift which saves a lot of time splitting sets just to get at one vehicle.

Hi Dave as requested here is Royal Oak June 1990 was lucky enough to get round the depot and see my second fave 017 by the jacks having last E :( and been repainted in RNSE dark blue.Maybe no interest as it not actually on the jacks but still interesting all the same as only 2 each side in this pic.

Thanks to all who have replied :D ,

Ian, photo is great, as it shows the same type of jacks made by Bachmann that I've just purchased :D .

So I'd summize from info given from replies, its usally 2 each side of loco , possibly near bulkhead area behind the cab ends i would imagine ? & more jacks used if the work involved is bogie removal or maybe needing major work to chassis.

thanks chaps,
Dave.

Not so sure about the older stuff but if you look down the sides of the more modern MUs such as the Voyagers you'll see the jacking points marked out with a little symbol, a sort of tilted line over a triangle.

Hope this image helps, maybe more on there but internet being very slow at the moment!

But four jacks are generally used.

Cheers

Daryl
