13.5.5 Extended Height/Packing

The extended height, and therefore the movement of the load, will be governed by the jack design. Where the load is to be raised a greater amount than the design of the jack will permit in a single lift, the use of suitable packing material will be necessary, both to rest the load on once the maximum jack movement has been achieved and to seat the jack on in order to allow a second lift to be made. Careful consideration must be given to the initial jack selection and to the selection of suitable packing material. (See section 13.10 SAFE USE OF JACKS)
