Greenhouse potted plant handling system - has overhead structure spanning aisles, for wheeled carriages which lift frames from trolleys in aisles

摘要

The system for conveying and handling potted plants inside a greenhouse includes an overhead framework for wheeled trolleys (20) passing from aisle to aisle and wheeled wagons which can be moved along the aisles. The overhead framework has end rails (13) supported by vertical straps (14) from the roof. Between them are supported cross members (17) acting as rails for the wheels (28) of the overhead trolleys (20). The trolleys have lifting cables (27) for an intermediate frame (25) to which can be attached the structure (45) of the wheeled wagons. This structure whic carries the plants, is lifted from the wheeled chassis of the wagon.
