Agricultural rollers on folding support frame - with lateral displacement during folding to restrict headroom when travelling on roads

摘要

The roller system has one set of rollers (9) supported under a central frame (13) with outer rollers (7, 8) on two outer frames (6) mounted on sliding frames (5) on pivots (12) at the ends of the main frame. The outer frames are extended to provide a wide working area. When the side frames are raised the sliding supports move the rollers along the side frames for a more compact arrangement, thereby reducing the height of the system. The slides are linked to cable pulls (15) attached to a central tensioner (18). Hydraulic rams (14) operate the folding action, with the ties automatically controlling the sliding action. USE/ADVANTAGE - Agricultural rollers with compact folded rig for road travel, simple erection process.
