1. Crane, Conveyor, and Rigging Part I - Crane OSHE 112, Spring 2016
Instructor: Mr. Chris Kuiper, CSP
Phone: 1

2. Review: Material Handling and Storage
Common daily operations and high injury rates
Manual lifting guidelines, rules, mechanical assistance, training, and PPE
Safety requirements for storage of different types of materials
Common hazards and control of cryogenic liquids

3. Crane Safety Overview Over 250,000 cranes in operation
125,000 in construction
80,000 general and maritime
80 fatalities per year
One death per thousand crane operators in their working lifetime (45 years)

4. Major Causes of Crane Accidents
Contact with energized power lines (45% of accidents)
“Under hook lifting device”
Overturned cranes
Dropped loads
Boom collapse
Crushing by the counter weight
Falls
Rigging failure

5. Regulations OSHA 29 CFR 1910, Subpart N: Material Handling and Storage
through , cover crane, derrick, and hoist safety
OSHA 29 CFR 1926, Subpart N: Cranes, Derricks, Hoists, Elevators, and Conveyors
through
ANSI standards

6. Crane Types Industrial cranes Construction cranes Overhead Gantry Jib
Mobile
Tower
Derricks

7. Industrial Cranes Overhead Cranes Common in industrial facilities
Supported by overhead rails
Components
Bridge
Trolley
Hoist
Often pendant or remote operated
Easy to use, little training required, no stability problems

8. capacity) gantry crane
Industrial Cranes
Gantry cranes
Similar to overhead cranes, but supported by a mobile frame which travels on the ground
Small (1000 – 10,000 pound
capacity) gantry crane
Large (600 ton capacity)
gantry crane

9. Industrial Cranes Jib cranes Pivot mounted boom with trolley and hoist
Wall-mounted jib crane
Floor-mounted
jib crane

10. Industrial Cranes Power hoist Chain hoist (or "chain fall")
Usually electric or air operated
Chain hoist (or "chain fall")
Hand operated

11. Construction Cranes Tower cranes Variable height “climbing cranes”
Used for building construction

12. Construction Cranes Mobile cranes
Crawler cranes
Truck cranes
Hydraulic cranes
Boom telescopes
May have jib
Equipped with outriggers for stability

13. Hydraulic Cranes

14. Hydraulic Cranes

15. Construction Cranes Derricks
Boom angle changes to adjust horizontal distance
Often used in shipyards, building construction, etc.
Gin pole
Chicago boom
Stiff-leg
Etc.

16. Derricks Mine-shaft rescue using a gin pole derrick improvised
from an extension ladder
Stiff-leg construction derrick

17. Controlling Crane Hazards
Operators
18 years old
Physical exam
Knowledge (training)
Estimating load weight
Signals
Operation
Skill (demonstration)

18. Controlling Crane Hazards
Inspection
Frequent
Daily, monthly
Hooks, rope, crane operation
Periodic
At least annually
Complete inspection: wear, damage, deterioration, operation
Slings
Testing
Records

19. Preventing Crane Accidents
Contact with energized power lines
De-energize lines
Maintain minimum distance
10 feet distance for 50 kv
Over 50 kv, add 4 inches per 10 kv
Use proximity alarms
Warn when energized line is near
Warning signs

20. Crane Incidents – Overhead Hazards

21. Crane Incidents – Improper Load Spreading
1250 Ton Crane lifting 350 tons. Mats provided but not used. 3 dead 2 critical.

22. Jib Crane Collapse - Wind

23. Tower Crane Collapse

24. Crane Collapses
Recent crane collapse in New York City Offshore

25. Crane Dum-Dum

26. CRANE ACCIDENT CAUSES Passerby struck by moving crane Overloading
Hoist Limitations
Rigging Failure
Improper Crane Assembly
Improper Crane Dismantling
Oversteering
Contact with a power line
Control Confusion

27. Who Is Liable? Crane Manufacturer Company Using the Crane
Corporation that owns the Site

28. Warning Label
                                                                     

29. Preventing Crane Accidents
Under hook lifting device problems
Inspect, proper use, etc.
Overturned cranes
Assure a level and stable base for the crane
Comply with load charts
Weight
Boom angle and extension
Only vertical loads
Wind can cause a significant side load

30. Preventing Crane Accidents
Dropped loads
Operating anti-two block device (upper limit switch)
Proper rigging
Inspection
Boom collapse
Stable base
No overloading
No horizontal loading
Crushing by the counter weight
Stay away from the rear of the crane

31. Preventing Crane Accidents
Rigging failure
Inspection
Proper use: temperature, angles, etc.
Falls
Fall protection for workers suspended by crane "man basket" or "suspended work platform"
Secure fall protection "above the hook"

32. Personnel Basket Offshore – The Right Way
Fall protection for workers suspended by crane "man basket" or "suspended work platform"
Secure fall protection "above the hook“

33. Personnel Basket Transfer – The Wrong Way
