ANVER also builds vacuum frames and individual vacuum generators for special applications, such as vacuum heads for automated equipment and manipulators. Usually the reason for a remote vacuum attachment is that it needs to be mounted on a pick-and-place machine or manipulator where weight must be minimized at the attachment head or there is not enough headroom for a complete lifter. Most such applications are one of a kind and designed for a specific task. Lifting beams with remote vacuum stations should not replace traditional operator controlled vacuum lifters as they always pose an inherent potential safety problem. With a standard vacuum lifter, you normally have a vacuum reservoir and check valve on the lifter frame. If power is lost or an airline or electric cord going to the lifter gets pulled out or cut, the unit will not lose the load. If it is a porous load then you may lose vacuum through the load, but, usually, you will have enough time to safely get out of the way. With a lifting frame and remote vacuum station, you need to be extremely careful of the supply hose going to the lifting frame. If you were to lose vacuum by having the hose get pulled out or cut, you would immediately drop the load since the vacuum reservoir and check valve are located at the remote station, not on the frame or hose leading to it. This is the main reason why lifting frames without built-in vacuum stations have limited use. However, if you have a special vacuum application, ANVER’s knowledgeable applications engineers can help you put together a Vacuum Lifting Frame suited to your needs. |
