<strong>DOE</strong>-<strong>STD</strong>-I090-<strong>96</strong> (Rev-I)14.2 STRUCTURAL AND MECHANICAL LIFTINGDEVICESa. Structural <strong>and</strong> mechanical lifting devices areoften one-of-a-kind designs. Typical devicesinclude:1. Load-supporting lifting devices(Figure 14-1).2. Friction-type pressure gripping liftingdevices (Figure 14-2).3. Indentation-type gripping liftingdevices (Figure 14-3).4. Cask lift fIxtures (Figure 14-4).14.2.1 Design/FabricationStructural <strong>and</strong> mechanical lifting devices shall bedesigned <strong>and</strong> fabricated according to theprovisions ofASME B30.20, 20-1.2.2.14.2.2 Markinga The rated capacity ofeach lifting deviceshall be marked on the main structure where it isvisible <strong>and</strong> legible. Ifthe lifting device comprisesseveral items, each detachable from the assembly,each lifting device shall be marked with its ratedcapacity. At a minimum, a nameplate, name tag,or other permanent marker shall be afftxeddisplaying the following data:1. Manufacturer's name (contractor'sname iffabricated onsite).2. Lifting device weight (if over 100 lb).3. Serial number (if applicable).4. Rated capacity.b. A rerated lifting device shall be relabeledwith the new rated capacity.c. 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 describe both its rated capacity <strong>and</strong> weight.14.2.3 Modification/Reratinga. Structural <strong>and</strong> mechanical lifting devicesmay be modified or rerated if the changes areanalyzed by a qualifted engineer or themanufacturer ofthe lifting device.b. Rerated or modifIed lift ftxtures shall beload-tested as described in Section 14.2.6.2,"RatedLoad Test," below.14.2.4 GuardingExposed moving parts or pinch points, such asgearing, chain drives, <strong>and</strong> rotating shafts, that maybe a hazard to personnel during lifting operationsshall be guarded.14.2.5 Inspections14.2.5.1 Initial InspectionPrior to their initial use, a qualifIed inspector shallinspect all new, modified, or repaired liftingdevices to ensure compliance with Section14.2.5.3, "Periodic Inspection:'14.2.5.2 Frequent Inspectiona. The operator or other designated personshall visually inspect each lifting device at thebeginning ofeach shift or prior to use, ifit has notbeen in regular service, for the following items orconditions (records are not required):1. Structural deformation, cracks, orexcessive wear on any part.2. Loose or missing guards, fasteners,covers, stops, or nameplates.3. All operating mechanisms <strong>and</strong>automatic hold-<strong>and</strong>-release mechanisms formisadjustments interfering with operation.4. The operator or designated person shallcarefully examine any defIciencies <strong>and</strong> determinewhether they constitute a hazard. Deficienciesnoted during the inspection shall be correctedbefore the lifting device is used.Chapter 14Below-the-Hook Lifting Devices 14-2
