Lifting Prop
This is a simple prop designed to aid manual lifting and positioning of heavy or awkward items. Typically used in pairs, they allow each end of a item to be lifted and propped - slowly increasing the overall height without undue effort or risk.
Example dimensions are given here, but these can be changed for different applications as required.

Use
A prop of this type can be used flat against a wall, and would be ideal for the temporary support and lifting of a heavy beam, or piece of equipment such as an air conditioner. The item to be lifted is placed on a pair of props with them set to a comfortable initial height. The operators can then lift an end by a small increment and extend the prop to take the weight. Moving from end to end to raised the whole item.
Transport
Remove the front brace and fold up the front leg. Take the main prop our of the box section, rotate a quarter turn and replace it back in. The props are now basically "flat".
