Abstract
An articulated aerial platform system having a lift assembly including an upper parallelogram riser and a lower parallelogram riser. The upper and lower risers are raised and lowered by a single riser cylinder mounted between a base of the system and the upper riser. Relative pivoting motion of the upper and lower risers is controlled by a timing link interconnecting the upper and lower risers. A work platform mounted at the end of a jib pivotally connected to a telescoping boom pivotally connected to the upper riser is leveled for boom motion by operation of a master cylinder and slave cylinder arrangement. The slave cylinder is disposed in a generally vertical position. A jib cylinder actuating motion of the jib is connected across the diagonal of the jib.
