Operational Safety – Before Lifting Below-the-Hook Devices Lifters must only be used bytrained operators. Do not allow yourself to bedistracted. Payy attention towhat you are doing. Test operation of movinglifter parts and controls at thebeginning of each shift.IllustrationOperational Safety – Before Lifting To ensure load is balanced andstable, make a preliminary lift of afew inches. Do not overload lifter. Do not try tolift a load that is too big for the lifter. Do not pick up hot loads unless thelifter is specially designed for hightemperature service.Check for cracks or structural damage.Check mechanical components for wearwear,alignment, and missing/loose hardware.Check all motors, controls, wiring. Checkthat all guards are in place and secure.For details, see below-the-hookpresentationOperational Safety – Before Lifting Do not overload crane orhoist. Make sure thecombined weight of thelifter and load does notexceed the rated loadcapacity of the crane orhoist. Refuse to make lift if youare unsure of any issues.Do not proceed until allissues are resolved.Operational Safety – Before Lifting Make sure hoist rope or chainis free from twists, knots andkinks. Multiple part linesshould not be twisted aroundeach other.8
Operational Safety – Moving a Load Take instructions onlyfrom the persondesignated to givesignals. Do not ride or allow otherpeople to do so. Do not lift load higherthan necessary to avoidobstructions in its path.Operational Safety – Moving a Load Stay clear while moving load. Do notallow load to swing. Use a rod topush load or a tag line to pull theload. Exercise particular caution withp loadsheet lifters. Be sure to keeplevel. Tilting the lifter could causethe load to slide off the lifter. Always lower load to ground andcheck its stability before leaving thearea.Crane Inspector – Definition Anyperson engaging in the testing,examination and/or certification ofcranes, including but no limited totop running and under-runningbridge and gantry type, single orgirder overhead travelinggdouble gcranes and associated hoistingequipment.Operational Safety – Moving a Load Do not allow loads to come in contact withother objects. Make sure the path of travel isfree of obstructions before moving the load. Do not lift loads over ppeople.p Stayy out fromunder the load and make sure other peopleremain at a distance. Avoid sudden starts and stops. Thisprevents shock loading which can stress thesystem beyond its capacity.Operational Safety – Moving a Load Make sure the lifter is properly stored after use. Liftersare big and heavy and can cause personal injury orproperty damage if they fail. Some lifter require aspecially designed stand. Others may be stored on alevel surface.Crane Inspector – Work Experience Shall have a minimum of 2,000 field hours of experiencerelated to maintaining, servicing, repairing, modifying andfunctional testing of cranes and associated hoistingequipment. Experience should provide a working knowledge of how toidentify deficiencies in mechanical, structural, electricalsystems and components of cranes.9

o 3.3.9 Bulk-handling crane o 3.3.10 Loader crane Overhead crane: An overhead crane, also known as a bridge crane, is a type of crane where the hook-and-line mechanism runs along a horizontal beam that it self runs along two widely separated rails. Often it is in a long factory building and runs along rails along the building's two long walls .
Overhead Crane Safety and Prevention Basic Crane Safety 1. No one but a regularly authorized operator is allowed to use any crane. 2. Do not carry a load over people on the floor. Sound warning devices to alert persons nearby. 3. Do not allow anyone to ride on a load carried by the crane or on the crane hook.
An Electric Overhead Traveling Crane or an Overhead travelling crane, also known as an Overhead crane or as a Suspended crane is a crane, which you usually see inside a factory or a warehouse. It travels on rails high above the ground. It normally has three different movements, which are driven by electric motors. Hoist is the drive lifting .
Double Box Girder of Eot Crane A 10 -ton capacity overhead crane of overall length 12.5m was selected for design optimization. Initially the self-mass of crane girder was found to be 7.3 tons. The configuration of the overhead crane is shown in Fig. 1.The overhead crane consists of two girders, two end carriage assemblies
