Abstract (en)
A lift is disclosed comprising two leg members (3,4) interconnected by a common central pivot (9). Each leg member has a roller (6,8) at one end and a fixed pivot (5,7) at the other end. On one ofthe legs (3) is a pivotally mounted link (11) which on one end is a roller (12) which when the lift is in its lower travel range is in contact with the other scissor leg (4) and on the other end is mounted one end of a ram (10) by a pivot (15) and whose other end is connected to the other scissor leg (4) by a pivot (13). This arrangement improves the mechanical advantage of the ram force required to open the scissor legs in the initial lift movement. <IMAGE>
