Farmers yard, forklift truck - Ground reinforcement

[adam7]

Hello,

New to this site looks good, cant find anything which answers my question.

We rent a cheap site, its a farms/builders yard, and have started to use a forklift truck it weighs 3.75 ton, and has a capacity to carry2.5 ton, total 6.25 ton, but we sometimes have 18 ridge lorries on the area, the ground is old concrete which in the past had fires on, which has started to break up and the forklift sunk with the weight in places.

I would like to raise the height by 80mm, the area that needs attention is around 80msq, The other parts of the yard (not the 80sqm) has had mot type-1 put down ages ago but over time has started to move over time.

My question is can I just put down MOT type-1, and use a wacker plate from a hire shop, is there a minimum spec wacker I should hire, and what is the minimum depth I require, and should i use the wacker in stages,

Any other ideas welcome

Regards

Adam

in our yard which regularly gets 15 tons tracked machines, tractors etc and 40 ton wagons we have a mix of 250mm reinforced concrete and 300mm of mot type 1 compacted in layers. i would recommend hiring the biggest compaction equipment you can sensible fit in and trust yourself to operate.

basically a whacker plate isn;t going to cut it for a commercial yard and the time it would take, you want something like a 800mm wide, 1.5 ton twin drum vibrating roller, and make sure you begin with a sound base, excavate any soft spots and then come up in 100-150mm layers and give it a good consolidating with the vibrating roller.



we run a 3 ton capacity rigid forklift across ours and its ok on the mot but better on the concrete, you will get wheel scrape on tight cornering with weighton, you'll also need to consider drainage etc

maybe get dig dug dans crusher and crush all the existing concrete
then as giles says use that as your subbase
a twin roller is a definite for a yard like that, and at least 225mm of c30 reinforced concrete,poured in bays
this was the spec we used at the cheese factory on the airport hill where the loading bays are (lots of artics and forkstrucks)
cheers

ive had serious problems with forklifts in the past, you cant really put them in the same category as heavy machinery especially 15t tracked machines which spread weight by design.

you will find that thats a lot of weight exerted on four tiny wheels, ie .5 of a ton for example on an area the size of your heel. this is further worsened by the rear wheels that turn on a sixpence and can easily dig in to a loose surface. you may well have a large wheeled model rather than a warehouse forklift, i dont know, but there are no shortcuts here. i would say you should concrete.

the posters location almost qualifies for free delivery and collection of the crusher ???

The first photo in GB's post is a factory based fork (outside) it has great lifting capacity ,but its wheels are designed for a flat smooth concrete floor as the footprint of the tyre is very small, hence sub-base movement .
The one in the second pic has similar lifting power on a short boom, but the important thing is, its designed for soft exterior work due to the large weight spreading tyre. the first pics is a Forklift, the second is a telehandler .
