Pulleys, gears and big machines, sentence 3

Cranes and lifts use a heavy counterweight like a seesaw partner, so the motor only has to lift the difference between the load and the weight.

Who acts: Cranes, motor · What happens: use, have, lift · To what, where: heavy counterweight, difference, load

This is a sentence of the lesson «Pulleys, gears and big machines» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Cranes, motor), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): no change. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
