Abstract
An apparatus (38) for tilting a pivotally mounted vehicle operator cab (21) has an actuator (40) for exerting a tilting force, a link (60) for directing the tilting force in a direction substantially perpendicular to the longitudinal axis (58) of the actuator (40), and a strut (46) for absorbing a substantial portion of the tilting force to prevent damage to the vehicle elements.

An apparatus (38) for moving a first member (21) pivotally connected to a second member (12) comprising:
- power means (40) for exerting a force and pivotally moving the first member (28);
- means (60) connected to the first member (21) for directing the force generated by the power means (40);
- force absorbing means (46) interconnecting the force directing means (60) and the power means (40) for effectively isolating a portion of the force generated by the power means (40) from said first member (21), said power means (40) and said force absorbing means (46) each having a longitudinal axis (58,56), said axes (58,56) being positioned within a first predetermined angle (A) having a range of approximately 4.degree. to approximately 10.degree..
