ARTICULATED AERIAL WORK PLATFORM SYSTEM |
摘要 |
An articulated aerial platform system (10) having a lift assembly including an upper parallelogram riser (22) and a lower parallelog ram riser (20). The upper and lower risers (22, 20) are raised and lowered by a single riser cylinder (38) mounted between a base of the system (10) and the upper riser (22). Relative pivoting motion of the upper and low er risers (22, 20) is controlled by a timing link (76) i nterconnecting the upper and lower risers (22, 20). A work platform (28) mounted at the end of a jib (26) pivotally connected to a telescoping boom (24) pivotally connected to the upper riser (22) is leveled for boom motion by op eration of a master cylinder (118) and slave cylinder (1 20) arrangement. The slave cylinder (120) is disposed in a generally vertical po sition. A jib cylinder (42) actuating motion of the jib (26) is connected across the diagonal of the jib (26).
