Balanced hoist
Red-chalk study of a counterbalanced lifting device shown in two views
In red chalk (sanguigna) Leonardo studies a balanced hoist (montacarichi bilanciato), a lifting mechanism designed to work against a counterweight. An upper plan-like view shows a boxed frame with cross-rails and rollers, while a lower perspective view opens the frame to reveal its rollers and platform.

Two studies show a hoisting frame carried on rollers within a rigid box structure. The device is captioned as a balanced hoist, its load meant to be raised and lowered against a counterweight running in the frame.
