Definition

A permanent raised overhead bridge-like structure used to support equipment while spanning over or around an object (for example: over a road or railroad, or around a ship hull or rocket).

Description

A gantry may be moveable (for example: a rocket gantry may be repositioned away from the launch pad when pre-launch preparations are complete). A 'scaffold' is a structure that may be similar in appearance but is assembled only for temporary use (for example: during external repair of a building).
