Vacuum Lifting
Devices are typically categorized as Below-the-Hook Lifting Devices by
the
ASME. Manufacturers, purchasers, and users of vacuum lifting
devices should be familiar with the safety standards developed for this
type of equipment which have been formulated under the general auspices
of the American National Standards Institute (ANSI). You will find many
other countries' standards are close to these.
The American Society of Mechanical Engineers (ASME) B30
Committee on Safety Standards for Cableways, Cranes, Derricks, Hoists,
Hooks, Jacks, and Slings has issued standard B30.20 for Below-the-Hook
Lifting Devices. This standard addresses the proper
marking, construction, installation, inspection, testing, maintenance,
and operation of vacuum below-the-hook lifting devices for non-porous
loads. All ANVER powered and mechanically operated vacuum lifting and
manipulating devices for non-porous load handling are designed,
constructed and tested in compliance with this standard.
Technically all users and purchasers of vacuum lifting devices are required to
follow these safety standards and have copies of these standards in their
facility. We are unable to
post even excerpts of this standard here due to copyright laws. However, copies
of this standard are available for purchase online (currently $69.00) thru the
ASME website
or by phoning the ASME at (800)THE-ASME and asking for the B30.20 -2010
Below-the-Hook Lifting Devices ASME publication.

Anver Vacuum Lifters fully Comply with the
North America ASME Standard which applies to complete lifters for non-porous
loads. |
- Full compliance to the latest
ASME B30.20-2010
standards for Below the Hook Lifting Devices and Vacuum Lifters
- In fact three of the five sketch drawing examples in
the ASME standard itself are Anver Mechanical Vacuum Lifters
- Product Safety Labels and Marking according to the
ANSI/NEMA Z535.4-2007 Standard
- Load-bearing Structural Components and Welding
according to ANSI/AWS D14.1 with a minimum structural Safety Factor of 3
to 1
- Electrical Equipment and Wiring according to ANSI/NFPA 70

In addition all ANVER Lifters feature: |
-
A unique
The VLS-08
Safety System to monitor the vacuum
level automatically and check for leaks.
- If vacuum is lost during a lift,
a loud horn sounds, and a red light flashes to warn the operator.
- The VLS-08
monitors vacuum level even if the operator is not looking at the lifter. Anver VLS systems are built
in to all lifters or sold as a mandated option.
- If vacuum is lost during a
lift, a loud horn sounds, and a red light flashes to warn
the operator (complying with European Standard DIN EN
13155:2009)
|
 |
- Anver builds its
lifters with large ergonomic front and side handlebar
grabs to keep the operator away from the load and ease
positioning.
- ANVER's
adjustable handlebar extends out to provide additional
leverage for the operator, and allows him to stand away from
the load for greater safety.

-
Vacuum hose with FDA approved clear PVC surrounding a steel
wire helix for reinforcement. Features full vacuum rating,
non-kinking/non-collapsible,
clear PVC that allows visual line inspection.
A glass smooth interior to reduce loss of flow.
-
ANVER vacuum lifters feature
nickel-plated vacuum fittings to ensure quality and
durability.

 |
- Locking vented ball valves
eliminate residual vacuum under cups which have shut off. If
vented valves are not used it is possible to think you have
vacuum under the pads when you do not. While not mandated,
we feel vented ball valves are a beneficial additional
safety feature on vacuum lifters.
Our ball-Valves also have a locking mechanism to add safety.
|
 |
- ANVER vacuum
lifters equipped with special ANVER manufactured check
valves. The check valves can operate in any
position. Our unique one piece housing make them to be leakproof, and have a low cracking
pressure and the highest flow available.

Plus we design and build to a higher standard:
- Anver designs and builds it's Lifters to a 2" maximum
load droop or sag unless otherwise noted for sheet and plate. This increases
the number of pads and beam lengths of our Lifters but it makes for safer
lifting with equally loaded pads and a level load.
How many cups do I need?
- Note: Some vacuum lifter companies design their lifters for 5" or more of
load sag (deflection) between each cup and the edge to make their equipment less
expensive. This makes for a smaller vacuum lifter with fewer pads but it results in lifters where centering
the lifter on the load is
critical or overloading of pads can cause sudden release. Having 5" of load sag is
excessive on a long heavy plate. The 2" max. sag Anver uses is not
mentioned in the ASME standard currently but it is likely that it will be
mandated in the future.
