Turtle Plastics Crib and Slab Pad – Composite Load Spreading Pad, 4" to 24"

A crib pad goes under the bottom block of a stack and spreads the load out over a bigger footprint. On soft ground, gravel, hot bitumen or a trailer deck, that is the difference between a stable tower and one corner slowly sinking. Five sizes, matched to the cribs and slabs they sit under, all with a moulded rope handle and a 3,000 psi bearing rating.

Specifications

How to choose

• Match the pad to the block above it. The pad names say it: Hybrid crib pad under a Hybrid crib, Slab pad under a Slab.
• Building a full tower on dirt? T-PCP24 – a 24 inch square base under the whole stack.
• Hot bitumen counts as soft ground. So does a gravel pad, a lawn, a trailer floor and most farm sheds.
• Jack itself needs a base too – see the jack pad listing linked below.

Technicians Advice

The cylinder lifts. The cribbing holds. That is the whole discipline, and the people who get hurt are the ones who forget the second half of it – a seal can pass, a hose can get knocked, a coupler can be half engaged, and a load held on oil pressure alone comes down. Build the crib as you lift: a little bit of stroke, a little bit of crib, repeat.

A tower built in 50 mm bites is stable and you always have support within a few millimetres of the load. Keep the stack square and keep it under about three times its narrowest base dimension in height – taller than that and it will walk under vibration or a knock. The capacity figures on this page are for a block loaded flat and evenly on a firm base; point-load the corner of a crib and the number means nothing, which is exactly what the pads are for.

On soft ground, on summer bitumen, or on a trailer deck, the jack needs a pad too – a 100 tonne ram sitting on a 100 mm base is putting the weight of ten cars through something the size of a saucer.

Things worth knowing: never mix timber and composite blocks in one stack, because they compress at different rates and the tower works itself loose; and the rope handles are for carrying the block, not for dragging a loaded one out from under something.
