Reference material Calculate areas and volumes of loads to the nearest whole unit Four step process



1.



Determine the length, width, height, diameter, and/or thickness of the load, as required



2.



Calculate the area or volume of the load, as required



3.



Find the weight of the load per unit of length, area, or volume



4.



Calculate the net weight of the load



Note: Before you begin calculating load weight, get an idea of how much the load should weigh. This serves as a way to doublecheck your calculation.



Step 1: Determine the length, width, height, diameter, and/or thickness of the load, as required You must know at least one dimension, length, width, height, diameter, or thickness to calculate the load weight. The dimensions you need depend on the type of load and type of weight tables you have. If the dimensions of the load are not shown on shipping papers or elsewhere, you must measure the load with a tape measure. These dimensions are measured in feet, inches, meters, or centimeters.



Note: When calculating load weights, you must use the same system of measurement (English or metric) for all values.



Certification Study Guide



June 2019

INFORMATION SHEET You determine load weight to see if the rigging equipment and methods will support a given load. If your rigging equipment capacity is rated in kilograms or metric tons, use metric units to determine load weight. If your rigging equipment is rated in pounds, use English units for load weight. Step 2: Calculate the area or volume of the load, as required For some loads, you will need to use the dimensions of the load to calculate the area or volume of the load. The dimensions you will need depend on the shape of the load. Area is often required for steel plate. For area, you need only the length and width of the load. Area is measured in square feet or square meters. Volume is generally used to determine load weights for stacks of lumber or bricks, concrete columns, or other solid loads with regular shapes. To calculate volume, you need length, width, and height or diameter, and length, depending on load shape. Volume is measured in cubic feet or cubic meters. Step 3: Find the weight of the load material per unit of length, area, or volume Handout 2.1.1 gives the weight per cubic foot or cubic meter of many raw materials. Every type of material has a specific weight per unit of volume. A cubic foot of Portland cement, for example, will always weigh the same amount: 94 pounds. The unit weight or weight per unit of volume for Portland cement is 94 LB/FT3. Handout 2.1.2 gives the weight per foot of steel plate. To use this table, you only need to know the thickness of the steel plate. One square foot of 3/8 inch-thick plate is 15.3 pounds. One square foot of 1 inch-thick plate is 40.8 pounds.



52 June 2019



Rigger I



INFORMATION SHEET Handout 2.1.3 gives the weight per linear foot of steel pipes. To use this table, you need to know the diameter and type of pipe. For example, standard (STD) weight pipe with a diameter of 0.84 inches weighs 0.85 pounds per linear foot. A 36 inch schedule 40 pipe weighs 282.36 pounds per linear foot. Handout 2.1.4 is a conversion chart from metric to English measurements. Step 4: Calculate the net weight of the load Multiply the unit weight by the total volume area or length of the load. For pipes, plates, and other construction materials that have special tables, you must multiply the weight of each item by the total number of items in the load.



Note: The four step process requires different load dimensions and different calculations depending on the shape of the load and on the availability of weight tables.

INFORMATION SHEET



Pipes You will frequently lift pipes. Special tables are available to help you determine the weight of metal pipes. To calculate the weight of metal pipes, you need to now the length, diameter, and thickness or type of pipe.



Note: To determine weights of pipes for which no tables are available (i.e., cement, plastic, etc.), use the technique described for columns.



Determine the dimensions of the load You need three dimensions to calculate the weight of a pipe: • Outside diameter or nominal pipe size • Pipe schedule number • Length

INFORMATION SHEET Calculate the area of the load You need to calculate the area or volume of a pipe if you have a pipe weight table. You need only the dimensions discussed above to find the unit weight on the pipe table.



Note: If you do not have a pipe weight table or if the pipe you are lifting is not on your table, treat the pipe as a plate that has been rolled into a cylinder.



Find the unit weight of the load material Weight of pipe = length of pipe x weight per linear foot To calculate the weight of a pipe, locate the diameter and nominal pipe size or schedule number in the table in handout 2.1.3. Read the weight per foot or meter given for that type of pipe.

INFORMATION SHEET Calculate the net weight of the load Find the unit weight of the pipe. Multiply the unit weight by the pipe length to calculate the weight of the pipe. For example, consider a schedule 40 steel pipe, 36 inches in diameter and 20 feet long. According to the table in handout 2.1.3, one linear foot of this pipe weighs 282.36 pounds. To calculate the weight of the entire pipe, multiply the weight for one linear foot by the length of the pipe. Weight = 282.36 LB/FT x 20 FT = 5,647.2 LB The steel pipe weighs about 5,647 pounds Sample problems You have a load consisting of 50 pipes secured together. Each steel pipe has three dimensions: outside = 0.84 inches, schedule number = 80, and the length = 20 FT.

INFORMATION SHEET



Plates Metal plates are standard construction materials. The most common plate you will see on the job is steel plate. Special tables like the ones used for pipe weights are available to help you determine the weight of steel plates. To use the tables, you need to know the length, width, and thickness of each plate in the load. Determine the dimensions of the load You need three dimensions to calculate the weight of a plate: • Length • Width • Thickness

June 2019 57



INFORMATION SHEET Calculate the area of the load The area of a plate = length x width Multiply the length and width measurements to calculate the area. You do not need to calculate volume for plates if you have the unit weight table for standard plate size. If a plate is 8 feet long and 4 feet wide, you find the area by multiplying 8 x 4. Area = 8 ft x 4 ft = 32 square feet



Figure 31



Figure 31 Rigger I Study Guide



Sample problems A plate has the following dimensions: length = 12 feet; width = 6 feet. Area of the plate = ____ square feet Find the unit weight of the load material Weight of a plate = area x weight per square foot Locate plate thickness on the table. The table provides weights per square foot for common plate thicknesses. For example, a 3/8” steel plate weighs 15.3 lb/sq ft.



58 June 2019



Rigger I



INFORMATION SHEET Calculate the net weight of the load Multiply the area of the plate by weight per square foot from the table. For example, the area of a given 3/8” steel plate is 32 square feet. Weight = 32 sq ft x 15.3 lb/sq ft = 489.6 lb Sample problems A steel plate has these dimensions: length = 10 feet; width = 8 feet; thickness = 1 inch. Weight of the steel plate = ____ pounds Sometimes loads will include more than one plate or pipe. When working with a stack of plates or bundle of pipes, you must know the total number of pieces and multiply the weight of each piece by the total number of pieces. For irregularly shaped plates, you must use specific formulas for various shapes, such as circles and triangles.

INFORMATION SHEET



Solid boxes (cubes) Sometimes you will lift rectangular or box-shape loads such as steel bars or bundles of lumber.



Note: For steel plates not listed on the plate tables, use the plate thickness as the height and treat the plate as a very short cube.



Determine the dimensions of the load To calculate the weight of a box-shaped load, you will need three dimensions: • Length • Width • Height

Rigger I



INFORMATION SHEET Calculate the volume of the load We must find the volume of a box-shaped load in order to determine its weight. To calculate the volume, multiply the length by the width by the height. The volume of a box = length x width x height. The box shown below has a length of 10 feet, a width of 5 feet, and a height of 5 feet. The volume of the box = 10 ft x 5 ft x 5ft = 250 cubic ft.



Figure 33



Figure 33 Rigger I Study Guide



Sample problems A box has the following dimensions: length = 8 feet; width = 5 feet; height = 3 feet. Calculate the volume of the box: ____ cubic feet Find the unit weight of the load material Use a unit weight table like the one in handout 2.1.1 to find the unit weights of materials like wood, steel, or concrete. The unit weights may be given in pounds per cubic feet or kilograms per cubic meter. Use the same system of measurement (metric or English) for all calculations.



Certification Study Guide

INFORMATION SHEET Calculate the net weight of the load Weight of a solid box = volume x weight per unit volume. To calculate the weight of a solid, box-shaped load, multiply the volume of the cube by the unit weight of the material. For example, a block of Portland cement with the dimensions:



Figure 34



Figure 34 Rigger I Study Guide



The table states that one cubic foot of Portland cement weighs 94 pounds. Calculate the weight of the cement block by multiplying the unit weight of cement by the volume of the block. Weight of the cement block = 94 lb/cu ft x 250 cu ft = 23,500 lb. Sample problems A rectangular load of spruce lumber has these dimensions: length = 20 feet; width = 8 feet; height = 6 feet.



Figure 35



Figure 35 Rigger I Study Guide



Weight of lumber = ____ pounds



62 June 2019



Rigger I



INFORMATION SHEET



Note: You can also use plate weight tables to calculate the weight of steel cubes. If you remember that a square foot of 1” thick steel plate weighs 40.8 pounds, how much does a cubic foot of steel weigh? A cubic foot of steel is the same as 12 1’ steel plates, 1 foot long and 1 foot wide. So, a cubic foot of steel should weigh 12 x 40.8 or 489.6 lb. Look at the material weight table for steel and you can verify this is true.

Columns Columns and poles are similar to pipes, except they are solid. Determine the dimensions of the load To estimate the weight of a column, you must know its volume. To calculate volume, you must know: • radius of the column • height or length of the column



Figure 36



Figure 36 Rigger I Study Guide

Rigger I



INFORMATION SHEET Calculate the area or volume of the load Volume of column =



πR2 x H



P (called “Pi”) is used to calculate the area of circles. Pi equals 3.14. On a calculator with a π key, π will have several decimal places, so your answers may be slightly different. R (radius) = diameter ÷ 2. R2 (“R squared”) = radius x radius. H = the height of the column.



Figure 37



Figure 37 Rigger I Study Guide



The diameter is 2 feet, so the volume = 1 x 1 x 3.14 x 3, or about 9 cubic feet.



Certification Study Guide

INFORMATION SHEET Sample problems A column has the following dimensions: diameter = 2 feet; height = 10 feet.



Figure Figure 38 38



Rigger I Study Guide



Calculate the volume of the column: ____ cubic feet Find the unit weight of the load material Use a material weight table to find the unit weight for the material you are lifting, just as you did for the cubic loads. Calculate the net weight of the load Suppose the volume of a concrete column is 36 cubic feet. One cubic foot of concrete weighs 150 pounds. You can calculate the weight of the column by multiplying the volume of the column by the unit weight of concrete. Weight = 36 cu ft x 150 lb/cu ft = 5,400 lb.

INFORMATION SHEET Treat empty boxes or pipes as two cubes or two columns: one outer box or column and one inner box or column. First determine the volume of the entire box or column. Then calculate the volume of the inner box or column. Finally, subtract the inside volume from the outside volume and multiply this figure by the appropriate material unit weight.
