Mewp on a sloped track

[jamesinwestwales]

We have a job coming up on dead ash over fibre optics so need to use a mewp. But The mewp will need to be set up on a steep driveway. 
 

my questions are, can this be done safely and how would you set a stable platform for the outriggers?  
 

is there a model of mewp that the outriggers are able to cope with a large difference in ground level?

 

we are in wales UK. 
 

thanks for the advice

It would depend on how steep an incline. I beleive Spider lifts have a set up incline upto somewhere near 34% or 19 degrees.

Depends to some extent on how steep the gradient is. Picture would be helpful. One of the worries can be the risk of the MEWP wanting to slide down the slope, and this needs to be addressed. I have done my MEWP training, and the refresher course, and this issue was not really discussed. I think this leaves those of us at the coalface having to decide for ourselves how to proceed.

I have had a spider on slope were the auto level wouldn't level it so had to do it manually. 

Best bet is if you can dig legs in on the up hill side.

I have done the IPAF training too and this wasn't discussed at all. just about driving them on a slope.  the slope is not so steep that a car can drive up it so i would say around 20-25% which seems to be within the range of the mewp i am going to hire for this job. I will be very aware of the mewp wanting to slide so will find a way to support it.  Its a rough tarmac track so may even drill into the old tarmac and secure some planks to prevent slippage.

 

Sorry not got any pictures

Dig the feet in and/or anchor them with ropes. Test by setting the boom to maximum sideways, minimum up and bouncing. Aware you won’t get a lot of sideways low down on a compound boom arrangement but you do what you can.

As its a hard drive way you maybe bet with a truck mount one company near me run a isuzu and saw it last year on a drive set up and the front bumper was nearly head hieght.

Spider will probably give you the best max slope angle due to the cranked legs. Your best not to set it up on a sloping hard surface because the platform could slip and throw sensors out. Best to dig out and level all leg pads which would be obviously a non starter on a drive? Unless you can set legs either side of a drive onto the garden?
