Ball Transfer Devices are special purpose devices that include a series of ball transfers closely spaced on a table. The individual ball transfers are rated for about 50 lbs. each and can be spaced on the table to provide various overall capacities as dictated by the application. No controls are associated with such transfers except for load present sensors that may cause the release of a load to the table.
These devices are often used in applications involving light loads and manual operations, such as feed tables to load formers.
