How is a crane lift plan prepared?
Lift Planning – 8 Steps for Better Crane & Rigging Operations
- Weight of load.
- Location of the load’s center of gravity.
- Overall maximum dimensions of the load.
- Location and quantity of approved lifting lugs / lifting points.
- Selection of the appropriate rigging gear to suit lifting points and center of gravity.
- Height restriction.
- Risk Assessment.

What is required in a lift plan?
Radius. The lifting capacity of the equipment being used. Net weight of the lift, plus the geometry of the item being lifted. All environmental obstacles or hazards along the lift’s travel path; these might include overhead power lines, other vehicles and workers in the area, etc.
How do you calculate lift capacity of a crane?
Measuring the dimensions of this triangle will allow you to achieve an accurate crane load calculation.
- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.

What is lifting plan in safety?
The plan may include sketches showing lifting points, methods of attachment, sling angles, load vectors, boom and swing angles, crane orientations, related capacities, and other factors affecting the equipment and lifting operation. The name of the Operator, Rigger and Competent Person.
Who can write a lift plan?
An appointed person who is trained and certified as per BS 7121 is required to prepare any lifting plan..
What is considered a critical crane lift?
Critical lift means a lift that (1) exceeds 75 percent of the rated capacity of the crane or derrick, or (2) requires the use of more than one crane or derrick. … Derrick floor means an elevated floor of a building or structure that has been designated to receive hoisted pieces of steel prior to final placement.
Does OSHA require a lift plan?
A Crane Lift Plan is required for every crane lift on a Dimeo project – see OSHA Subpart CC for definition of crane. … The Crane Lift Plan may be valid for more than one day, as long as the configuration, location, and parameters used for developing “worst case” condition have not changed.
What is the lifting plan?
Lifting plan is a set of plans which is created for use in any crane lifting operations and it consists of all the important information that must be considered in a lifting operation thus ensuring that the lifting operation is carried out safely.
Do I need a lift plan for a telehandler?
When all of the documents are consulted, it is clear that lift plans are not a requirement for telehandlers unless they have an attachment which converts their use as a crane. Also there is confusion of an Appointed Person to complete lift plans and a person appointed to plan and risk assess a load being moved.
How much can a 50 ton crane lift?
Produced by Terex, the American HC 50 is a hydraulic crawler crane that’s nimble, yet, very capable of performing tough tasks. It has a 50 ton (45.4 t) max lift capacity, 160 ft. (48.8m) max lift crane boom length, and a 130+40 ft. (39.6+12.2 m) max lift crane boom & Jib length.
How much can a 40 ton crane lift?
It’s easy to tell how much a particular hydraulic truck crane can lift just by the name of it: A 40-ton crane can lift 40 short tons (80,000 pounds or 36,287 kilograms).
What crane can lift the most weight?
Guinness World Record
Taisun holds the world record for “heaviest weight lifted by crane”, set in Yantai on April 18, 2008 at 20,133 metric tonnes (44,385,667.25 lb) by lifting a barge, ballasted with water.
What is a crane lift plan?
A rigging plan is developed every time a heavy load is being lifted. The basic idea behind a rigging plan is to have control and establish safety precautions. It is an important planning process that will identify all hazardous situations that might be encountered during lifting.
What is tandem lifting?
When lifting heavy or oddly shaped objects, it is sometimes desirable to use two cranes in tandem rather than a single higher-capacity crane. Tandem lifts can be very useful, and they are often used to place structural beams for bridges, move large loads, and lift long components from horizontal to vertical positions.
What lifting means?
Lifting. Moving or bringing something from a lower level to a higher one. The concept encompasses biomechanic stresses resulting from work done in transferring objects from one plane to another as well as the effects of varying techniques of patient handling and transfer.
