ABSTRACT:
The disclosure involves a material handling machine such as a lattice-type portal crane having an elongate lattice girder suspended from a girder beam by a first and second support links. In turn, the girder beam is supported at an elevation by a pair of legs. The improvement comprises a force transfer link coupling the support links so that forces transferred between the girder beam and either leg are isolated from the girder. The girder, which is triangular-shaped, has a top apex-like chord member and a pair of lower chord members. The support links and the force transfer link support the girder at the lower chord members and the top chord member is spaced (and therefore, isolated) from the girder beam.
