The petard was the first 'shaped' explosive charge, used by a Mining Engineer (colloquially 'sapper') to precisely direct a blast onto a single point, like a lock or door hinge, when mining toward a defended structure during a siege. It was shaped like a squat cone and because of this shape, concentrated a small charge so well that the sound of the blast rarely carried through the door to the defender. This enabled the sapper to use such a small charge that he could remain quite close to the spot. So close, in fact, that it was conceivable that a sapper might be 'hoist by his own petard' if he was a bit of a show-off. First printed reference was in Shakespeare's 'Hamlet' III.iv.207 "For tis the sport to haue the enginer Hoist with his owne petar"

Hoist
A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.

There is an irony that he is killed with his own poison (hoist with his own petard, one might say). Also, since Laertes knows he's going to die, he has an incentive to spill the beans on Claudius: "The king's to blame!"
The reference can be found in Hamlet (Act 3, scene 4)There's letters seal'd, and my two schoolfellows,Whom I will trust as I will adders fang'd-They bear the mandate, they must sweep my wayAnd marshal me to knavery. Let it work;For 'tis the sport to have the enginerHoist with his own petard, an't shall go hardBut I will delve one yard below their minesAnd blow them at the moon.Shakespeare didn't invent the term though.
