<strong>DOE</strong>-<strong>STD</strong>-<strong>1090</strong>-<strong>96</strong> (Rev-1)14.3 VACUUM LIFTING DEVICESTypical power-operated <strong>and</strong> mechanicallyoperated vacuum lifting <strong>and</strong> manipulating devicesare shown in Figures 14-5 <strong>and</strong> 14-6. This sectiondoes not cover devices used to h<strong>and</strong>le porousmaterials, which requires special design <strong>and</strong>construction.14.3.1 Design/FabricationPower- <strong>and</strong> mechanically operated vacuum liftingdevices shall be designed <strong>and</strong> fabricated accordingto the provisions ofASME B30.20, 20-2.2.2.14.3.2 Markinga. The rated capacity, maximum width <strong>and</strong>length, <strong>and</strong> minimum thickness ofload shall bemarked on the main structure where it is visible<strong>and</strong> legible.b. Individual pads or groups ofpads, controlledby shutoffvalves, shall be marked with the ratedcapacity ofeach pad or group ofpads.c. At a minimum, a nameplate, name tag, orother permanent marker shall be affixed to eachlifter displaying the following data:1. Manufacturer's name.2. Model number or unit identification.3. Weight oflifting-device.4. Electric power (when applicable).5. Pressure <strong>and</strong> volume of compressed air(when applicable).6. Rated capacity.d. <strong>Manual</strong> shutoffvalves on individual pads orgroups ofpads shall be marked to show operatingposition.e. Cases may exist where a lifting devicecannot be marked with its rated capacity <strong>and</strong>weight. This may be due to the securityclassification ofthe load to be lifted or otherreasons approved by the responsible manager. Inthese cases, the lifting device shall be marked withan identification number, <strong>and</strong> its documentationshall contain both its rated capacity <strong>and</strong> weight.f. A label or labels shall be affixed to eachvacuum lifting device in a readable position thatdisplays the word "WARNING" or other legenddesigned to bring the label to the attention oftheoperator. The label shall also contain informationcautioning against:1. Exceeding the rated capacity or liftingloads not specified in the manufacturer'sinstruction manual.2. Operating a damaged ormalfunctioning unit or a unit with missing parts.3. Operating when vacuum indicatorsshow insufficient vacuum.4. Operating the unit when vacuum padsare not spaced for equal loading.5. Incorrect positioning ofthe liftingdevice on the load.6. Lifting people.7. Moving loads above people.8. Removing/obscuring warning labels.9. Operating the lifting device when therated capacity, lifting-device weight, or safetymarkings are missing (except in cases where thedevice cannot, for security or other reasons, bemarked).10. Making alterations or modifications tothe lifting device.11. Lifting loads higher than necessary<strong>and</strong> leaving suspended loads unattended.g. A label shall be affixed to each unit thatdirects the user to consult the manufacturer'smanual if the size or shape ofthe unit prohibitsthe inclusion ofthe above markings.14-7Chapter 14Below-the-Hook Lifting Devices
