 How
to Set-up Self-Powered Mechanical
Vacuum Lifters
No Power Service is Needed so Set-Up is Straightforward
How A Self
Powered Mechanical Vacuum Lifter Works
The Upward/
Downward Movement of
the Hoist Controls Vacuum Attachment and Release.
The
Simple On/Off Cycle is Quick and Reliable
 |
| Basic Operating
Procedure
|
- The lifter hangs from a crane hook and is lowered
onto the load until the chain is slack.
- The lifter is pulled up by the hoist, creating a
vacuum, and picks up the load.
- The lifter and load are set down until the chain
is completely slack, which releases the vacuum.
- The lifter can now be raised without the load.
- Set the lifter down until the chain is completely
slack and you're ready to pick up the next load.

Description |
|
The vacuum generator consists of
a free-moving piston within a closed cylinder. A rubber rolling diaphragm forms an
airtight seal between the piston and cylinder. Since the integrity of this seal does not
depend on metal-to-metal contact or a tight fit, it does not lose efficiency with
use.
The
vacuum attach-and-release cycle is controlled by an automatic self-cycling valve located
in the bottom of the piston. When the unit is lowered onto the load and the suspension
chain slackens, a cam automatically closes the piston valve. The hoisting action then
pulls up the piston, creating a powerful vacuum inside the cylinder and underneath the
vacuum pads.
When the load is completely set down, and the suspension chain is again
slackened, the cam opens the piston valve, releasing the vacuum. The lifter then can be
raised, ready for the next pickup. Attach and release are instantaneous. Since the valve
sealing disc can only cycle when the chain is completely slack, it cannot shift positions
while in use and will not accidentally release the load.

| Unique
Features
|
- Instant attach and release
is provided via the hoist up and down movement. The attach and release alternates each lift cycle for fast,
efficient handling. Mechanical vacuum lifters increase the speed and efficiency of
the horizontal
handling of sheet and plate, panels, and all types of nonporous
materials.
- Simple
to operate. One person can control the entire operation. No oil fumes or noise pollution.
- Easy to
Maintain. Only the highest quality components and superior
construction are used with few moving parts.
- Extremely
Safe. Load cannot be released until it is set down on a surface.
- ANVER Mechanical Vacuum Lifters are suitable
for 100% duty cycle 24 hour a day operation. They never overheat or burn
out.
- Easy to Maintain and Keep Operating in
Heavy Production Environments. No wires or hose to tangle up in the hoist chain; no
fuses, motors or switches to replace. ANVER Mechanical Vacuum Lifters cannot overheat and
are not affected by electric power brownouts.
- ANVER Vacuum
Lifters
comply fully with and meet the standards of US
ANSI ASME Standard B30.20 for below-the-hook lifting devices, as
well as complying with OSHA and European CE Mark requirements.
