6) The load must be properly rigged and attached, with the initial lift made slowly to verify that the load is rigged correctly and to ensure that the crane is stable.

7) The operator and qualified signal person must use standard hand signals. Contact may also be made via radio. If the operator loses communication with the signal person, operations must stop until communications are restored.

8) Pick-and-carry operations, typical of RT cranes, call for additional considerations. Operators should be aware of soft ground, ruts, rocks, and holes. Also must be aware of slope of ground and platform level before during and after lift.

9) While moving the crane, the operator must be aware of the changing environment, including overhead obstructions and other equipment or people that may have entered the working area.

10) Once the lifting work is completed, then lowering the boom; unpinning and re-pinning various crane elements; and stowing all elements for travel must be done in a safe manner.

Veteran crane operators with outstanding safety records keep their record distinguished by double-checking everything beofre they make a lift. Those operators pay careful attention at all times and will not tolerate horseplay or unsafe conditions. Crane safety must be No 1 on the crane operator's extensive checklist.

Crane Safety Tips, 1 through 5

1) All operators must be trained in all aspects of safe crane operation and have thorough knowledge of load charts and set-up of the crane for a particular lift.

2) Before going to the job site, truck cranes and all-terrain cranes need to be checked to ensure that they are set up for safe highway travel. Regular maintenance of the carrier as specified by the manufacturer is important.This includes recommended daily checks, as well as maintenance of the superstructure, boom, turntable, outriggers, and counterweights.

3) Ground conditions at the job site need to be checked frequently to ensure that conditions have not changed from previous day.

4) The operator must consider the size and shape of the load as well as wind direction and boom length.
5) Crane operators must have a keen awareness of power lines and be constantly aware of electrocution hazards.
