This lifting device is designed for loading and unloading concrete hollow core slabs or tiles. The hooks have a chain to allow multiple slabs to be lifted simultaneously. The hollow core slabs are lifted from the outer end in the hollow space. It is best to checking the suitability for lifting hollow core slabs with the manufacturer. Always use a chain or cable with a length that is at least 60% of the length from the suspension points. Always check that the hollow core slabs are sufficiently strong and that there is sufficient material at the suspension points. These hooks are not as suitable for positioning hollow core slabs as the hooks are longer and more space is needed to remove the hooks.
