ABSTRACT

At least one embodiment relates to a lift device including a chassis, a series
of tractive elements coupled to the chassis, an implement, and a boom coupling
the implement to the chassis. The boom includes (a) a first shell including a
first sidewall and a first transition coupling a first set of flanges to the
sidewall and (b) a second shell including a second sidewall and a second
transition coupling a second set of flanges to the sidewall. The first shell
abuts the second shell along the first set of flanges and the second set of
flanges. The first transition and the second transition extend along a length
of the boom. The first transition and the second transition at least partially
define a channel. The first shell is coupled to the second shell by a weld
positioned within the channel.
