# Aerial work platform with linkage damping

## Abstract

A lift device and a method of controlling the lift device are provided. The lift device has a linkage assembly supported by a chassis, a work platform supported by the linkage assembly, and a hydraulic system. The hydraulic system has a lift cylinder to move the linkage assembly between a retracted position and an extended position, and a damping cylinder to increase stiffness of a pair of linkages positioned between the distal end of the lift cylinder and the work platform. When the linkage assembly is being extended, the lift cylinder receives pressure from the hydraulic system at a first pressure and the damping cylinder receives fluid from the hydraulic system at a second pressure, the second pressure lower than the first pressure.
