Anver Corp. (Hudson, Mass.) has announced a new version of its mechanical vacuum lifter which features a large rectangular suction pad for lifting heavy blocks of aluminum, steel, and plastic. The M250M mechanical lifter requires no external power because it has a self-cycling valve and piston that creates a powerful vacuum when lowered from a crane onto a load until the chain slackens fully and is raised again. It features a new 21-by-29-inch (533-by-737-mm) sealing ring suction pad which can be replaced in the field using a common Allen wrench. The vacuum lifter has a 2,800-lb/1,270-kg capacity for feeding cutting tables and machining centers. Standard features include all-welded steel construction, a vacuum loss sensor, and an audible and visual alarm. Custom pickup head options are available to accommodate various loads. Cost of the lifter is $3,495.
