Abstract
A mast assembly having a base, and a mast pivotally connected to the base for movement between a horizontal and an upright position. A linear actuator is connected between the base and the mast and is extensible to move mast about the pivot. A strut is selectively positioned between the mast and the base to inhibit pivotal movement toward the horizontal position during lifting of the mast. A plurality of abutments on the base permits selective connection between the actuator and the base. The strut position supports the mast while said actuator is moved between the abutments.
