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.

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
