Title: DUAL ACTUATOR ASSEMBLY
Abstract:
A boom assembly (40) includes a lower boom (50), an upper boom (70), and an actuator assembly (100). The lower boom (50) has an upper end (54) and a base end (52). The base end (52) is configured to be pivotally coupled to a lift device (10). The upper boom (70) has a lower end (72) pivotally coupled to the upper end (54) of the lower boom (50). The actuator assembly (100) has (i) a first end coupled to at least one of the upper end (54) of the lower boom (50) and the lower (72) end of the upper boom (70), and (ii) an opposing second end coupled to the upper boom (70). The actuator assembly (100) includes a first actuator and a second actuator (see: 120; 140). The second actuator is rigidly joined to the first actuator at the first end (see: 160) of the actuator assembly and flexibly joined to the first actuator at the opposing second end (see: 178) of the actuator assembly (100).
