Abstract
A clamp device () includes a plurality of arms (). One of the arms supports a securing member (). The other arm includes a curvilinear surface () that directly engages a curved wall of an article at a location in line with a centerline of the securing member. The curvilinear surface () 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.
