发明名称 Lift arm structure for a work vehicle
摘要 A lift structure for a work vehicle including a pair of lift arms arranged on opposite sides of the work vehicle, each lift arm having a first end pivotally coupled to the work vehicle and a second end for coupling to a tool. Each lift arm includes a first side plate member, a second side plate member, an elongated top tubular member and a bottom member. Each side plate member has a plurality of pivot orifices including at least one pivot orifice near each end of the side plate members and at least one intermediate pivot orifice located between each end of the side plate members. The elongated top tubular member is attached between each of the parallel side plate members at the top edge so as to connect to each side plate member. A bottom member is positioned in a spaced relationship from the top member between each side member and is connected to each side member. The top tubular member provides additional strength to the side plate members to resist bending and torque loads. A traverse torque member is mounted between each lift arm and is connected to each side member of each lift arm. A material handling tool, such as a loader bucket, can be coupled to the second end of each lift arm.
