Abstract
Improvements in the mechanisms of tilting by counterweights, essentially characterized by consisting of a basic general framework, in the form of a bridge, integrated by a horizontal upper chamber that houses the fundamental pulleys, mounted in bushes welded to the chamber itself, and on ball bearings to improve its rolling, from whose pulleys the tractor cables derive, one on each side of the assembly, towards the counterweight and the guide roller of the panel to be tilted, housed respectively in two other adjacent columns that complete the aforementioned frame.
