Safe Lifting Learning Video - Rigging Safety Training

The essence of safe, efficient crane operation is keeping the crane and its load under control at all times. Job planning During the initial job-planning stage of the construction operation, the company should decide what its crane requirements will be. Then plan for a crane or cranes adequate to accomplish the job. When selecting a crane, consider a variety of factors other than crane capacity. These may include terrain, ground conditions, weather conditions, crane mobility and/or overhead utilities. The Crane The crane should be in good mechanical condition with sufficient lifting capacity to perform the work required. The crane also should have documented periodic (usually annual) inspections and documented frequent (daily to monthly) inspections. Make sure lifting charts and operator manuals are available onsite. The Operator A qualified operator is experienced in operating the crane; knowledgeable in methods, means and limitations of crane use; able to conduct frequent inspections of the crane; and able to read and interpret crane load charts and operator’s manuals. This operator should be in good physical condition with judgment unimpaired by drugs, alcohol or fatigue. The Load To properly plan the lift, the weight of the load, including rigging, headache ball, load line, etc., should be known. If the weight is unknown, a knowledgeable person should calculate it. Other factors you may need to consider are center of gravity and attachment points for rigging. The Rigging Rigging consists of the slings, shackles and spreaders that attach the load to the crane and are designed for the load. Like the operator, the rigger should be qualified through training or experience to determine the best method and equipment to secure the load to the crane. This is one area of crane operations that is often overlooked. The Lift Begin the lift by ensuring that the crane is level and on a base with sufficient strength to support the load and pressures generated during the lift. Be sure the swing radius for the boom and counterweight is clear of personnel and equipment. Check for any overhead obstructions, and make sure that the clearance for electrical utilities can be maintained throughout the lift. Perform a trial lift. This lift is one where the load is picked up only a few inches from the ground or the staging surface and held. This lets the operator and rigger observe if the choices of crane configuration, line parts, rigging and rigging equipment are correct. If the load shifts or something has been overlooked, land the load and stop the operation until adjustments are made. Accomplish the lift in a conservative manner. This means making smooth, steady motions, not too fast, with the load under control at all times. Make no sudden changes of direction or speed. During the lift, never allow the load to swing over personnel. Use taglines to control the load. #riskassessment #lifting #liftingsolution #workplacesafety #hse #rigging #hazardidentification
