Greenhouse with movable plant troughs - has troughs mounted in end brackets with pairs of offset wheels on rails

摘要

The greenhouse has gangways between plant tables, and plant troughs movable above the tables. The troughs (18) are secured at both ends in brackets (20), supported by two wheels (21,22) on rails (19) extending above the tables for their entire width. The wheels are offset from each other in the lengthwise direction of the rails near the bracket ends, one running against the top and the other against the bottom of the rail. One of the wheels (21) is coupled to a driving shaft (24) running parallel to the gangways, and coupling two or more brackets together.
