PON-GX series lifters are widely used for carrying and installing raw glass and glass curtain walls. Our system uses the American THOMAS DC vacuum pump and Panasonic DC battery. This means our system has everything you need, and you donâ??t need to connect to other air sources or power sources. Our digital display vacuum pressure switch and battery charge indicator monitor in real time to ensure the equipment is operating efficiently and safely. Our added vacuum pressure charging system ensures the whole vacuum system maintains a relatively constant safety pressure during operation. Four extension arms and four assembly methods allow you to adapt the device perfectly to different glass sheet sizes. Product: X-type four-paw vacuum lifter with manual rotation/tiltâ??
