Crane SafetyTraining

A "crane" is a machine for lifting and lowering a load and moving it horizontally, with the hoisting mechanism an integral part of the machine. Cranes whether fixed or mobile are driven manually or by power.

Crane

Mobile Crane Gantry Crane Tower Crane Mechanical Crane

Type of Crane

There are two type of Lifting.1. Manual Lifting2. Mechanical Lifting (Crane, Chain Block)

Type of Lifting

There are four type of it.1. Light Lifting2. Heavy Lifting3. Critical Lifting4. Tandem Lifting (Lifting the Load two crane or more)

Type of the Crane Lifting

Before OSHA was created 43 years ago, an estimated 14,000 workers were killed on the job every year. It means 38 Fatalities injuries in a day.

( Dr. David Michaels Assistant Secretary of Labor for Occupational Safety and Health )

Crane-Related Deaths in Construction by Year, 1992-2006*

Hazards in Crane Operation

Power line Contact Rigging Failure Structure Failure Tip over Swing Radius Crushing

Improper Setup Inadequate outrigger cribbing. Unstable ground (Utilities, uncompacted soil, etc.) Inspection failure - damaged components. Unlevel crane .

Causes of Crane Failure

Mechanical Failure Hydraulic Failure Impact Loading Side Loading Wind

Overload

Minimum clearance 10 ft. up 50kV plus 0.4 inches for each 1kV over 50 kV. In transit with no load 4 ft. - upto 50kV 10 ft - 50kv to 345kV 16 ft - upto 750kV

Power lines - OSHA

When the crane moves to within the booms length a designated signal person is required !

Powerlines - ANSI B30.5

Prohibited Zone Up to 50 kV 10 ft. 50 to 200 kV 15 ft. 200 to 350 kV 20 ft. 350 to 500 kV 25 ft. 500 to 750 kV 35 ft. 750 to 1000 kV 45 ft.

Power lines - ANSI B30.5

Contact With Overhead Power Lines Death % Worker on foot touching/guiding load or cables 40 39% Operating crane 32 31% Worker on foot touching crane 19 19% Other** 11 11% Total 102 100%

* Includes 7 deaths of operators who jumped from crane. ** Includes 6 deaths of workers on foot near crane.

Chain Block Shackle U Clump Wire Slings Belts Chain Slings

Rigging tools / Lifting tools

Sling Stress

Wire Rope Capacities

Wire rope shall be taken out of service when any of the following conditions exist:1. In running ropes, six randomly distributed broken wires in one lay or three broken wires in one strand in one lay; 2. In standing ropes, more than two broken wires in one lay in sections beyond end connections or more than one broken wire at an end connection.3. Wear of one-third the original diameter of outside individual wires. Kinking, crushing, bird caging, or any other damage resulting in distortion of the rope structure;4. Evidence of any heat damage from any cause;

Rigging Inspection Checklist

Rigging Inspection Checklist

Immediately remove damaged or defective slings from service

Rigging Inspection Checklist

Broken Strands

Crushed Rope

Damaged wire rope must be taken out of service

A cutting edge cuts the life of the sling.

Use blocking, padding, or a corner saddle when the cable must go around sharp corners

Rigging Inspection Checklist

Rejected Wire Slings

Shackle Type

. Use only the proper pin, never replace with Bolts.. Never use a screw pin shackle if the pin can roll under Load.

Shackle Use

Shackle Inspection

1) Only authorized and competent person should be operated the crane.2) Operator and rigger must be certified from third party.3) Crane must be certified from third party .4) Lifting equipment must be certified from competent authority and mark with its SWL.

Safety Checks

5) Check the condition of the ground before parking the crane and use out riggers.6) All moving parts must be guarded.7) Load chart must be available with crane.8) Area should be barricaded with safety signs when the crane operation is in progress.9) Never be used for loads excess of its SWL.

Safety Checks

10) Never stand or work under a suspended load.11) Tag line shall be used to control swing of lifted materials.12) Never operate the crane at the time of wind speed.13) Outrigger should be fully opened and placed it metal plates / wooden pallets if the soil is soft.

Safety Checks

Safety is a full time job – don’t make it a part time practice.
