Turtle Plastics Step Chock – Composite Stabilisation Chock, 4,400 kg

A step chock is what a rescue crew slides under a sill or a wheel arch to take a vehicle off its suspension in seconds. Four moulded steps, so there is a shelf at whatever height you need, and a rope handle to drag it into place. Composite, non conductive, and it does not care about fuel, oil or coolant on the ground.

Ways to buy

Specifications

How to choose

• Vehicle stabilisation? This is the tool. Slide it under the sill, drop the vehicle onto the nearest step, and the suspension is out of the picture.
• Pair it with wedges. The chock takes the weight, the wedge takes up the last gap.
• Heavier than a car? Go to cribbing blocks – the step chock is rated to 4,400 kg.

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. Two more 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.
