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.
How do you make a crane lift plan?
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 the purpose of a lift plan?
It is not and should never be considered generic. The purpose of this lifting plan is to identify the control measures necessary to negate the primary hazards of the: ● crane overturning ● load falling from the crane ● load or machine striking someone or any other identified hazard.
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.
How is SWL of Crane calculated?
SWL or WLL are calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
Who is responsible for a lifting plan?
Under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), an employer must ensure that each lifting operation is planned by a ‘competent person’. BS 7121 Code of Practice for Safe Use of Cranes, states that “the competent person for planning lifting operations is referred to as the appointed person”.
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.
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.
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.
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.
What does a 100 ton crane mean?
100 ton means, that theoretically the crane could lift one metre from the center of the column 100 ton. … The base formula for the Crane Capacity Index is: * For each main boom length at each radius the “Lifting height*Capacity” is calculated.
What are the procedures for safe lifting?
Proper Lifting Technique
- Keep a wide base of support. …
- Squat down, bending at the hips and knees only. …
- Keep good posture. …
- Slowly lift by straightening your hips and knees (not your back). …
- Hold the load as close to your body as possible, at the level of your belly button.
- Use your feet to change direction, taking small steps.
What is routine lifting operation?
Routine Lifts. This classification comprises: • Routine crane operations. • Repetitive lifting operations using the same equipment (e.g. drilling. activities), and.
What is a pick plan?
The pick plan can generate the material storage locations to pick from using the directed picking rules, a specific material storage location, or the default shipping location. If the Work Order Pick Plan process errors during processing, use the Release Inventory Locks page to release the records from processing.
What is lifting plan in weaving?
Lifting Plan: Lifting Plan defines the selection of heald frames to be lifted or lowered on each successive insertion of weft yarn. In a lifting plan, the vertical spaces indicate the heald shafts and the horizontal spaces indicate the picks. The lifting plan is drawn at the right side of the weave plan.
