Abstract
A clamp device (30) includes a plurality of arms (32, 34). One of the arms supports a securing member (36). The other arm includes a curvilinear surface (40) that directly engages a curved wall of an article at a location in line with a centerline of the securing member. The curvilinear surface (40) allows for the clamp device to reliably engage an article having a curved wall for a lifting operation. One example use of a disclosed example device is for lifting tubes associated with a hydraulic elevator system.
