# Pulleys, gears and big machines, sentence 7

<!-- .ven lang=en -->
A crane uses pulleys, a long arm and a heavy counterweight that balances the load like a seesaw, and it has a load limit for each distance along the arm so it does not tip over.

<!-- .vintro -->
**Who acts:** crane, long arm, pulley · **What happens:** use, balance, have, not tip over · **To what, where:** pulleys, load, load limit

<!-- .vabout -->
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 (crane, long arm, pulley), 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): R5-strong ×1, R7-rel-agree ×1. **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.
