Abstract
An extension boom system for heavy equipment having, the extension boom system including a first actuator mounted on a base, and connecting a second stage, a second actuator mounted on the second stage and connecting the second stage to a third stage, a third actuator mounted on the third stage and connecting the third stage to an extendable portion, and a controller configured to control the first actuator, the second actuator, and the third actuator so as to selectively operate in a first operation mode and a second operation mode. In the first operation mode, the first actuator, the second actuator, and the third actuator are operated substantially simultaneously, and wherein in the second operation mode, two of the first actuator, the second actuator, and the third actuator are actuated substantially simultaneously, while another of the first actuator, the second actuator, and the third actuator is not actuated.
