Battery-Powered Vacuum Lifting System The GRABO® PRO is a battery-powered vacuum lifter designed to handle smooth, textured, and semi-porous materials with a secure vacuum grip. Its 20 L/min vacuum pump and digital pressure monitoring system maintain consistent suction while lifting tile, stone, glass, concrete, metal, wood, and other flat materials. Automatic Vacuum Pressure Control The integrated pressure monitoring system automatically manages vacuum performance by stopping the pump when 11.6 PSI (0.8 Bar) of vacuum pressure is reached and restarting it whenever pressure drops. This automatic operation helps maintain lifting performance throughout material handling. Designed for Professional Material Handling With a maximum lifting capacity of up to 375 lbs (170 kg), the GRABO PRO is suitable for transporting a wide range of construction materials. Four integrated anchor points allow compatible lifting straps and accessories to be attached for additional handling options.
