Load i.e. pig mold, handling device for use in stage-house of theatre, has robots handling pig molds between bottom and top foot bridges of pig mold and carriage of counterweight of maneuvering module of theater set and vice versa

摘要

The device has two robots (42, 46) for handling pig molds (34) between bottom and top foot bridges (40, 44) of the pig mold and a carriage (32) of a counterweight (30) of a maneuvering module of a theater set (14), and vice versa, where the bridges store the pig molds. A lift transfer the pig molds between the bridges, accessible to the robots. A sensor (52) measures force exerted on one of two strands (26, 28) of a maneuvering wire (20) connected to the counterweight.
