<strong>DOE</strong>-<strong>STD</strong>-I090-<strong>96</strong> (Rev-I)9.4 MAINTENANCE9.4.1 Preventive Maintenance until all guards have been reinstalled, trapped aira A preventive maintenance program based onthe crane manufacturer's recommendations shouldbe established. Dated records should be madeavailable.b. Replacement parts shall be at least equal tothe original manufacturer's specifications.c. All moving parts ofthe crane for whichlubrication is specified shall be regularlylubricated. Lubricating systems should bechecked for proper delivery oflubricant.Operators <strong>and</strong> maintenance personnel shall followthe manufacturer's recommendations as to thepoints <strong>and</strong> frequency oflubrication, maintenanceoflubricant levels, <strong>and</strong> types oflubricant to beused.9.4.2Maintenance Proceduresa. Before starting adjustments or repairs on acrane, maintenance personnel shall take thefollowing precautions as applicable:1. Place the crane where it will cause theleast interference with other equipment oroperations in the area.2. Lower the lower load block to theground or otherwise secure it against dropping.3. Lower the boom to the ground, ifpossible, or otherwise secure it against dropping.4. Place all controls in the OFF position<strong>and</strong> secure all operating features from inadvertentmotion by brakes, pawls, or other means.5. Ensure starting means are renderedinoperative.6. Stop the power plant or disconnect itat the power takeoff.7. Relieve hydraulic oil pressure from allhydraulic circuits before loosening or removinghydraulic components.b. Warning or out-of-order signs shall beplaced on the crane controls. Signs or flags shallbe removed only by authorized personnel.c. Mter adjustments <strong>and</strong> repairs have beenmade, the crane shall not be returned to serviceChapter 9Mobile Cranes 9-12has been removed from the hydraulic system,safety devices are reactivated, <strong>and</strong> maintenanceequipment is removed.d. For locomotive cranes:1. Employblueflag protection on eachside ofthe crane (except dead ends).2. Place derails not less than 50 it fromthe crane on each side (except dead ends).3. Allow only authorized personnel toremove warning signs, flags, <strong>and</strong> derails.9.4.3Wire-Rope MaintenancePersonnel using wire rope shall ensure proper careby doing the following:a. Store rope to prevent damage ordeterioration.b. Unreel or uncoil rope as recommended bythe rope manufacturer <strong>and</strong> with care to avoidkinking or inducing a twist.c. Before cutting a rope, place seizings on eachside ofthe place where the rope is to be cut toprevent unlaying ofthe str<strong>and</strong>s. Flame-cuttingwire rope is prohibited.d. During installation, avoid dragging the ropein the dirt or around objects which will scrape,nick, crush, or induce sharp bends in it.e. Maintain rope in a well-lubricated conditionto reduce internal friction <strong>and</strong> to preventcorrosion. Ensure that lubricant applied as part ofa maintenance program is compatible with theoriginal lubricant. Consult the rope manufacturerwhen in doubt. Lubricant applied shall beofthetype that does not hinder visual inspection. Thosesections ofrope that operate over sheaves or areotherwise hidden during inspection <strong>and</strong>maintenance procedures require special attentionwhen the rope is lubricated.f. When an operating rope shows greater wearat its ends than on the remainder, its life can beextended (in cases where a reduced rope length. isadequate) by cutting offthe worn end, thusshifting the wear to different areas ofthe rope.
