Crane-Hydra-Deployment for Lifting-Lowering-Risk Assessment

Activities

• Preparation and checking before entry
• Entry inside plant
• Preparation and checking before Lifting
• Lifting/ Lowering of the load

Hazards

• Fire extension due to spark generated
• Damage due to hitting against pipe/equipment
• Injury to people around
• Property damage / Exposure to toxic release/ fire due to falling of lifted load/ crane toppling due to improper usage of the crane
• Exposure to HC/toxic release due to Crane rope getting entangled with a small-bore connection
• Property damage / toxic release/fire due to dropping of the load to slippage of slings, rupture of slings, crane brake failure, rupture of crane rope wire, slippage of rope wire from the anchor point
• Property damage/ exposure to toxic release/fire due to toppling or collapse on the crane
• Electrical shock hazard due to entangling with overhead electrical cables
• Hazard due to high wind velocity

Control Measures

• Crane/ Hydra must have a valid permit for entry inside red roads
• Crane/ Hydra must be certified for use by the P&M department
• Driver must have a safe driving licence. Spark arrestor must be healthy
• Check LEL in the proposed route of the Crane/ Hydra. Switch off the engine and evaluate if the F&G alarm is sounded
• Crane/ Hydra will move with a speed of less than 10 Kmph
• Identify all pits near to the route, barricaded /highlight if required
• Use wheel jammers to prevent accidental movement of the Crane /Hydra
• Keep the Crane / Hydra on gear when parked. Follow Vehicle entry procedure
• Do not leave the crane / Hydra unattended when parked near plant and machinery
• Do not allow to move people in the route of Crane/ Hydra
• Crane/ Hydra reverse horn must be working and assistant to guide while reversing

Following things are to be ascertained before lifting:

• Object load;
• lift radius;
• load height;
• load centre of gravity;
•  load suspension point;
• Slew Limitation;
• counterweight;
• Bearing load on the ground;
• Safe working load;
• Object dimension (if more than 25m2), safe approach. Also, give the request form to P&M depth so that the correct crane is allocated
• Check on Crane /Hydra:
• Crane load test certificate, Daily log sheet, Fortnightly / monthly service and inspection checklist must be available and updated. The safe load indicator (SLI) is working. If not working capacity loading will not exceed 60%.
• All limit switches are functioning. The free-fall system is blocked.  No hydraulic oil leakage 

Lifting plan to be prepared if: 

• load wt is more than 15T or Boom length above 55m or two cranes used for single lift or capacity loading more than 85% or using mobile crane rated above 200T     
• Identification and marking any small SBC at risk and pointing out the risk to the crane operator and signaler
• Lifting weight to be with guide rope. Optimal setting of the crane and restricting crane movement. Also barricade the crane
• Crane has undergone regular and competent service, inspection
• Control of slings wear and tear and the attachment to the load
• Crane capacity loading (85 % with working SLI, 60 % if SLI is not working)
• Load weight and lifting radius must be known and within crane capacity
• The area must be barricaded; people should not be allowed under lifted load
• low capacity loading, working SLI, setting of crane outriggers on the solid foundation
• Proper operators under the outrigger’s required. The outriggers must always be extended in their full length
• Elec. Overhead line is at least 6.0 m above from tip of the crane
• Wind speed should be less than 19.4 knots (35 km/hr). For personnel lifting wind speed should be less than 14 knots
