Make sure that the swinging area of the crane is free of structure, equipment and workers. • Lifts shall not be made in winds that exceeds that manufacturer’s recommendation or in winds 32Kph or greater without approval from the rigging supervisor. |
|
| 2.3 Poor crane lifting practices. | • Test lift prior to lifting Avoid lifting a load that exceeds the capacity of the crane and over reaching of load. • Avoid swinging of loads on a high speed manner. Use tag lines to control loads. • Any personnel are not allowed to ride on a load. • Maintain constant communication for all involved personnel on the activity. Use two-way radio if there are obstructions between riggers and operator which cause difficulties in coordination. • Crane’s swinging radius must be properly barricaded. Install warning signs Danger, Lifting in Progress. • Use proper personal protective equipment (PPE) like gloves Safety Glass, Safety Shoes & Hard Hats. |
|
| 3. Erection & fit up of pipes spool/flange using crane. | 3.1 Unstable grounds/ strong winds. 3.2 Unsecured loads during lifting 3.3 Poor crane lifting practices |
• Check wind velocity prior to lifting and ground stability for outriggers. Fully extend outriggers with wood matting prior to lifting. • Conduct daily and visual inspection to all rigging hardware and crane parts prior to lifting. • Secure load by competent rigger and use appropriate rigging tackles with visible SWL and has 3″ party certified. • Inspect rigging tackles before each use for wear & tear and make sure has color code for the current month. • Observed double choked for long load to prevent slips and use tag lines to properly hold and control the load. • Trial lift prior to lifting avoid lifting a load that exceeds the capacity of the crane and over reaching of load. |
