The HS N 6450 hand lifting unit has a maximum load capacity of 79 kg. Its deep, concave suction disc (Ø 250 mm) ensures simple suction grip of curved or irregular, nonporous surfaces. The radius of the curved load must be at least 330 mm. It is not suitable for use with thin, fragile materials. The Red Line indicator warns the user of impending loss of vacuum, and the unidirectional valve allows re-pumping without losing the remaining vacuum pressure. Loads can be released completely and quickly with the valve release lever. The protective carrying case is included.
