Abstract
A lift arm assembly includes a first arm casting including a first end, a second arm casting including a first end, and a tubular cross member attached to the first arm casting and the second arm casting. The lift arm assembly also includes a first arm tubular member including a first end attached to the first end of the first arm casting. The lift arm assembly further includes a second arm tubular member including a first end attached to the first end of the second arm casting such that the second arm tubular member is generally parallel to the first arm tubular member. At least one of the tubular cross member, the first arm tubular member, or the second arm tubular member has a continuous periphery, a maximum of one seam, and a substantially constant cross-section along substantially an entire length of the respective member.
