Skyscraper(1928)

Blondy and Swede are gruff best friends who build skyscrapers. Blondy gets sweet on a girl he saves from a falling beam, Sally, but when he is injured in an accident and temporarily crippled, he rejects her. Swede tries every desperate measure to get Blondy to fight back, to try to walk, even masquerading as stealing Sally away from him.
