<p>The loader platform has the opposite link arms (18, 19) of the lifting gear (15) for the platform connected by a torsion tube (coupling device) (23). One link arm is fixed to one end of the torsion tube and cannot rotate on it, while the other is able to turn on the other end (26) of the torsion tube, so that the lagging arm is pulled up to eliminate any gap.</p> |
