  • Patent number: 4883145
    Abstract: A simple apparatus is disclosed that reduces the risk of low-back injury to workers in elevated, partially enclosed, aerial baskets. The preferred embodiment basically comprises a circular well within the floor of the basket that is surrounded by a raised footrest platform adapted to receive on foot of the worker. Between the footrest platform and a base of the well is a cylindrical wall that prohibits forward movement under the footrest platform.In operations, when the worker has to perform manual handling tasks outboard of the basket, one foot is raised out of the well and extended forward onto the footrest platform, while the other foot remains below and behind the raised foot, on the base of the well. The worker has thereby adopted a forward leaning posture instead of a forward bending posture. Consequently, the worker retains the optimal curvature of the spine, while achieving a biomechanical advantage that reduces the work demand on the lower back.
