Sicurezza e Conformità
Importanti linee guida sulla sicurezza e avvertenze d'uso per il tuo GRABO®.
GRABO® non è progettato né destinato all'arrampicata né a sostenere il peso di una persona. L'uso di questo prodotto per l'arrampicata o qualsiasi altro scopo non previsto può causare lesioni o morte.
AVVISO: A causa dell'alta pressione creata da GRABO®, si consiglia vivamente di non fissare GRABO® a vetri di spessore inferiore a 6 mm. Il vetro di spessore inferiore a 6 mm può subire danni.
Safe Operating Guidelines
Follow these steps every time you use your GRABO® to protect yourself, your team, and your load. A vacuum lift is only as safe as the surface, the seal, and the operator.
Respect the Working Load Limit
The GRABO® Pro Brushless is rated for a Working Load Limit (WLL) of 265 lbs (120 kg) on non-porous surfaces. It was tested to 530 lbs (240 kg) under ideal conditions, but local regulations require a 2:1 safety margin. Never exceed the stated safe lifting values.
Prepare the surface and the seal
The contact area must be clean, dry, and free of dust, grit, or debris. Inspect the foam seal for wear, cuts, or contamination before every lift, and replace it if it is damaged.
Confirm full vacuum before lifting
Activate the pump and watch the pressure gauge and LED indicator. Only begin lifting once a full, stable vacuum has been established and the suction holds.
Keep clear of the load
Never position yourself or others beneath a suspended load. Keep hands, feet, and bystanders out of the load path at all times.
Match the surface to the tool
GRABO® holds best on flat, non-porous and semi-porous surfaces with a peak-to-valley height under 0.1 in (3 mm) and a surface arc under 5 degrees. Porous or heavily textured materials reduce hold.
Operate within rated conditions
Use the tool between 32°F and 140°F (0°C to 60°C). Do not use a unit with a damaged body, worn seal, or compromised battery.
Working Load and Surface Suitability
Safe lifting capacity depends on the tool, the material, and how clean and even the surface is. Select a GRABO® tool below to see its rated hold by material. Always apply the 2:1 safety margin and never exceed the Working Load Limit.

Perpendicular hold is the rated pull straight away from the surface; parallel hold is the rated pull along the surface (shear). All values assume a clean, even surface with peak-to-valley height under 3 mm and a surface arc under 5 degrees. Real-world capacity varies with surface condition, cleanliness, and porosity.
Battery and Charging Safety
GRABO® runs on a 20V (18V EU) lithium-ion battery platform. Handle and charge it with care.
- Charge only with the supplied GRABO® charger (100 to 240 VAC, 50/60 Hz) in a dry, ventilated area.
- The charger LED shows red while charging and green when the battery is fully charged.
- Do not charge or use a battery that is damaged, swollen, overheated, or wet.
- GRABO® lithium-ion batteries are UN38.3 tested for safe transport. Follow IATA (air) and IMDG (sea) rules when shipping.
Maintenance and Inspection
A reliable vacuum seal is essential to safe lifting. Keep your GRABO® in good condition with regular checks.
- Inspect the foam seal before each use and replace it when it is worn, cut, or contaminated. With heavy use this is roughly every 3,000 lifts.
- Always disconnect the unit from power before replacing a seal or filter.
- Keep the pump intake and filter clean, especially in dusty working environments.
