![]() ![]() This training course will help employers in providing the proper and necessary OSHA required training concerning crane hand signal safety. While other signals are permissible, hand signals are the most common means of communication between an operator and signal person. Standard hand signals are universal and used worldwide. If that ability is interrupted, the operator must stop operations until signals are re-established. The ability to transmit signals between the crane operator and the signal person must always be maintained. Through the use of signals, the signal person is able to help the crane operator move loads safely to the desired location.Īll directions given to the operator by the signal person must be given from the operator’s perspective. The signals used and means of transmitting signals to the operator must be appropriate for site conditions. A signal person provides this assistance and in some situations is required. ![]() Mobile cranes include crawler mounted, wheel-mounted, rough terrain, all-terrain, commercial truck-mounted, and boom truck cranes. Often crane operators are unable to see the moving load or the surrounding area. Mobile cranes: These cranes use a lifting device incorporating a cable suspended latticed boom or hydraulic telescopic boom designed to be moved between operating locations by transport over the road. There are significant safety issues to be considered, both for the operators of the diverse “lifting” devices, and for workers in proximity to them. Much technology has been developed for these operations, including careful training and extensive workplace precautions. While the signals we’ve discussed are not a comprehensive list, they should be a review for properly trained crane operators.Moving large, heavy loads is crucial to today’s manufacturing and construction industries. Understanding the subtle nuances between different hand signals will help you avoid miscommunication and do your job more efficiently. They will indicate this by pointing the index finger up and making a circular motion below the other hand’s palm. The load will occasionally be heavy or unstable, and the signalman will tell you to raise the load more slowly. Look at some unique rigger hand signals through Hard Hat Training’s Rigger Signalman Training. This also shows that you want the boom closest to the attachment. Grabbing your forearm indicates that the knuckle boom needs to be moved. Sometimes you have to be specific about what kind of boom needs to be moved. The rigger signalman will extend their arm with the thumb up and quickly open and close the other fingers. This message basically combines the signals for “boom up” and “wire down,” which tells operators to float the load. The signalman will tuck in the thumb otherwise, it might look like the “boom up” rigger hand signal. Swing, slew, rotate craneĮxtending the arm tells operators to swing the load, and the arm’s direction will tell you where you should swing. You could imagine that the signalman is giving you a thumbs up. This safety training video provides an overview of the crane signal persons role, responsibilities, signals and safety considerations while working onsite. The main difference is that the arm is extended and the thumb is pointed up instead of the index finger. This rigger hand signal may seem similar to raising the load. Check out OSHA’s pictures of this hand signal. When the signal person gives directions to the operator, they must be from the operator’s perspective. The only exception is if other personnel see a hazard, they can use the emergency stop signal. The signal person is the only one who should give signals to the operator. The signal involves pointing the index finger up and moving it in a wide circle. Standardized hand signals are commonly used by the crane signal person. Wire up, hoist up, raise loadĪs you may have guessed, this signal is basically the opposite of the previous one. This occurs when the worker wants you to bring the load down. The rigger signalman makes this signal by point the index finger down and moving it in a circular motion. 7 Handy Rigger Hand Signals Wire down, hoist down, lower load Therefore, knowing some common hand signals will help you more efficiently do your job and reduce the risk of accidents. While only the professionally trained can give signals, it is the crane operator’s job to interpret and understand them. Using hand signals is an important method of communication for the rigger signalman. Crane Signal Person Basic Training is an important resource to help crane signal people and crane operators learn the 20 standardized hand signals as. Luckily, we have the rigger signalman, who uses rigger hand signals when visibility and verbal communication is difficult. When working around crane rigging, communication can mean the difference between a normal workday and a fatal accident. Communicating at construction sites can be a day-to-day struggle, especially if the noise is so loud that you can’t hear the sound of your own voice.
