GRABO Vacuum Lifter Pro Version with Electronic Display for Wood Drywall Granite Glass Tile Porcelain Suction Tool GRABO Pro is equipped with a robust vacuum pump. The foam rubber vacuum seal on the GRABO Pro tool is strong and resistant to loss of vacuum pressure. Once the pressure pump is activated, it creates a strong suction and firmly attaches to any non-porous flat surface. The suction is strong enough to hold firm even loads as heavy as 375 lbs . In order to lift any slab of flat solid material, simply turn on the unit and place it straight on the surface. The GRABO Pro automatically monitors the vacuum and if vacuum pressure is lost the pump is automatically powered up until the vacuum pressure is restored. The handle is also equipped with a digital display that shows the maximum weight that the GRABO Pro can safely lift at that very moment. The weight is displayed in both pounds and kgs. The Pro-Lifter is equipped with a smart digital pressure sensor. This makes it even more effective on different surfaces. With a simple press of a button the lifting function is automatically activated and regulated. The sensor automatically provides for the optimum level of suction, keeping objects in complete control whether the object is being lifted or even during movement. The digital display on the grab handle shows the pressure applied in both bars and psi. With the pressure sensors, you don’t have to worry about turning the vacuum pump on or off. In fact, the automatic sensor is especially useful when lifting and moving coarse materials. The sensors digitally detect and maintain the required pressure while transferring the object being lifted . This provides for precision handling and installation without too much of a hassle. In any case the sensor automatically stops the pump on reaching maximum vacuum capacity of 11.6 PSI. Can easily complete the handling work Can handle manhole covers with raised patterns that are not too high Can be used for uneven surfacese Package Contents: 1 GRABO Pro tool (2021 model with digital display) 1 multi-socket charger 1 seal (preinstalled on the tool) 1 battery (preinstalled on the tool) 1 tough Oxford fabric carry bag 1 Operator’s manual in English Grabo Electric Vacuum Suction Cup Lifter Worksite Perpendicular Hold Parallel Hold Glass 170kgf / 375lbsf 120kgf / 265lbsf Metal 110kgf / 242lbsf 110kgf / 242lbsf Plastic100kgf / 220lbsf 100kgf / 220lbsf3 Wood 100kgf / 220lbsf 65kgf / 143lbsf Ceramic Tile 170kgf / 375lbsf 120kgf / 265lbsf Rough Concrete 80kgf / 176lbsf 80kgf / 176lbsf Dry Wall 75kgf / 165lbsf 65kgf / 143lbsf Rough Slate 80kgf / 176lbsf 80kgf / 176lbsf Grabo Safety Note The grabo is not designed or intended for climbing or securing people in any way.
