Hoisting and winding engines (see [Nos. 1222], [1223]) are balanced by having an ascending and descending cage, and two ropes, one winding on as the other winds off the drums.
Double cage hoists similarly balance themselves. Heavy slide valves, and other reciprocating parts of steam engines, are balanced by small steam pistons. See [Nos. 1651]-[1654].
Foot treadles, when required to always stop at a point off the dead centre, have a balance weight fixed to fly-wheel, at right angles to the dead centre.
