Crane Practices of the Past Relied on operator

Operating from the seat of your pants

Annual inspection confirmed by sticker on the crane

Then we asked for annual inspection

Inconsistent use of cribbing

Partial extension of outriggers

Tires not off the ground

Oilers on cranes

Crane Best Practices Maryland New Crane Standard

Rigger 1

Rigger 2

Master Rigger

Notification of erecting, climbing or disassembly

Federal New Crane Standard

Qualified Rigger

20 foot rule on Power lines

Relying on the Crane OperatorFour ways to be an operator;

Certification by an accredited crane testing organization

Qualification by an audited employer program

Qualification by the U.S. Military

Licensing by a government entity

Before You Make The Lift Crane Lift plan

Critical Lift Plan

Tandem Lift Plan

Tripping Precast Lift Plan

Hoisting Personnel

Crane Lift Plan Crane Load Chart;

Downloaded from websites; the charts state:This chart is a guide and should not be used to operate the crane.

Computerized programs such as;

3D Lift Plan:Not for Construction Use, For Pre-Planning Only

Computerized plan may give an in -between radius

Example of radius on chart: Did Crane Manufacture Approve? 30 foot radius 55’ boom = 20,600

32.5 foot radius 55’ boom = 18,050

35 foot radius 55’ boom = 15,500

Critical Lift Plan Above 75% of Crane configuration

Could cause and environmental or hazmat condition

Unique or irreplaceable item

More than one piece of equipment required to make the lift , stabilize or support the load

Personnel are being lift

Tripping pre-cast panels

Above 85% have a PE Evaluate and approve your Plan

Assembly or Disassembly Each Crane has a written procedure!

Is it part of your lift plan?

Did you read the procedure?

Is the procedure being followed?

Rigging and Hardware Capacity

Angle

Vertical or Choked or Basket

Shackle Capacity

Shackle and Pin designed for each other

Spreader beams capacity and annual inspection

If the crane configuration capacity is determined to be 73% of capacity and the rigging due to size or angle is at 94% capacity would you treat this as a critical lift?

Annual & Monthly Inspection Qualified Inspector

Verify Serial Number to Crane brought on site

Verify expiration date

Deficiencies – documented repairs

Monthly inspection available

Cribbing

Equal to 3 times the area of the outrigger float

Crane lift capacity divided by 5 equals the square footage of cribbing required under each float

Comply with the manufacture

Designed by a professional engineer

Failure to bring any cribbing with the crane

Not Enough Room to Extend Outrigger

Ground Bearing Pressure

Designed by Professional Engineer

Job Hazard Analysis Assembly

Disassembly

Climbing (jacking)

Maintenance
