\nMoving heavy loads around a work environment demands careful attention to safety. Accidents can take a hefty toll in life, limb, and material damages. A fundamental knowledge of inspection, maintenance, and operating procedures can make the difference been smooth operation and a tragic mishap.<\/p>\n

THE EQUIPMENT<\/p>\n

Reducing the likelihood of hazards during crane rental<\/a> operation depends on several factors. We\u2019ll cover a few of the basics here. Overhead and gantry cranes have three axes of directional travel: vertically in the direction of the hoist and load hook, laterally along the path of the trolley, and forward and back along the path of the bridge. Operators and\u00a0drilling contractors<\/a> should be trained in the crane\u2019s capabilities, movements, speed, control settings, and safety devices.<\/p>\n

While cranes are made of high-strength steel, one should never exceed the crane\u2019s rated load capacity. Attempting to move a load greater than the crane\u2019s capacity can put undue stress on the equipment and can endanger workers. Second, controls must be inspected regularly to be sure that all motions agree with the controls as marked. When working with overhead and gantry cranes, be alert for excessive drift or irregular stopping distances. Check hooks and wire ropes for damage or fatigue (excessive wear, nicks, gouges, fraying, broken strands, kinks, or deformations), and be sure all wire ropes are properly reeved. Be sure that any damage noted on daily inspections is properly documented, marked, and reported to supervisory personnel. Wire ropes should never be wrapped around a load or used as slings unless specifically designed for this use.<\/p>\n

Also, check that upper-limit devices stop the load properly. Staying alert for other trouble signs\u2014such as oil leaks or unusual sounds\u2014not only promotes safety but may help avoid costly repairs. Be sure that all provided warning devices\u2014bells, gongs, sirens, strobes, etc.\u2014are in working order. Also check that the crane or hoist has not been tagged with a lock-out tag or cut-off order sign.<\/p>\n

Finally, a clean and well-lighted work area can prevent mishaps. All cranes require regular maintenance to ensure safe operation. See the manufacturer\u2019s guidelines for information and requirements.<\/p>\n

THE LOAD<\/p>\n

Moving large loads safely depends a great deal on the load itself. For example, loads should be stable and balanced. Testing a load by lifting it a few inches can help to determine whether the load is stable enough to be moved to its destination. Loads should be moved smoothly and at safe speeds to avoid jerking and shifting. Loads should never be moved over areas where other employees are working. Do not use cranes to attempt a sideways pull of a load. When not in use, loads should be lowered and secured. If a crane is to be left unattended, the operator must land any attached load, place the controllers in the \u201coff\u201d position, and open the main switch. Before closing a main switch, all controllers must be set in the \u201coff\u201d position.<\/p>\n

THE HUMAN ELEMENT<\/p>\n

The best asset in crane safety is having trained and qualified personnel. Well-trained operator and workers can mean the difference between safe operation and a needless hazard. Operators and workers who understand the safety features of their equipment are far less likely to experience costly or life-threatening accidents. An emergency response plan in the event of an accident can help prevent or reduce injury and damage. Attorney Stephen Phillips<\/a> provides legal advice on such cases. To ensure safe and accurate operation, workers and operators should know and practice proper hand signals. (See page 10 of the CMAA Crane Operator\u2019s Manual for detailed illustrations of proper hand signals.) The crane operator should respond only to signals from the worker directing the lift. In the event of power failure, the operator must place all controllers in the \u201coff\u201d position. Workers should remain on the work floor and should never \u201cride the load.\u201d Manual warning devices (when provided) or verbal cues should be used to warn workers when a load is beginning to move or when workers are in the path of the load. No repair, inspection, maintenance or other work should be done under a suspended load.<\/p>\n","protected":false},"excerpt":{"rendered":"
