Hand Vacuum Cups and Suction Cups
Push or Slap-On Type Suction Hand Cups Used primarily for light sheet, lift and place applications
These simple, hand-operated vacuum cups and suction cups are well suited for handling non-porous sheet and plate materials in the horizontal position. This is an old proven design used primarily for light sheet products. A typical application would be lifting light sheet from a skid to a table for example. Creates less vacuum than other hand cups such as the lever or pump action styles. Not suitable for vertical handling. Features:

Caution: These suction hand cups are only designed for momentary hand use on small or awkward loads without other natural handles. Their indicated carrying capacities are for handling clean, dry, smooth, non-porous surfaces at sea level with clean, dry, undamaged seals, properly used. We state their carrying capacity conservatively with a 4 to 1 vacuum safety factor when correctly attached. We recommend not exceeding this as our carrying capacities are realistic in real world conditions.
We recently revised our capacities down but we feel you will find our more conservative ratings are accurate for what is safe in most applications. Along with actual load testing, vacuum hand cup capacities are calculated by a formula based on determining the surface area (cup diameter) under a fixed vacuum level and then dividing by a factor for safety. If you see a competitive cup of the same size with more capacity, it is simply that the competitive cup has a lower safety factor.
These hand cups are totally unsuitable and unsafe for attachment to hoists, manipulators, fork-lifts or for use with any other lifting method or device. For such applications, please see our information on our Powered Vacuum Lifters and Vacuum Tube Lifting Systems.
