## Calculation JIB Crane

## INPUT GENERAL DATA

In the first part of the Jib Crane calculation software, you must enter your detailed and accurate data. You can change the approximate data below to achieve your desired results. Jib Crane calculation software is designed for boom box and boom beam modes. Jib Crane calculation software is designed according to the standard. For example, first enter the diameter of the column and the thickness as an approximation, and in the end you will get the desired result by changing it because this parameter depends on other parameters such as the weight of the crane.

## TROLLEY HOIST DATA

In the second part of the jib crane calculation software, you have to enter the data related to the lifting trolley. The width of the wheel and the number of wheels have a great effect on the tension of the boom. Lifting and trolley speeds, the diameter of the lifting drum of the jib crane have an effect on the power of the lifting and transverse motors.

## BASE COLUMN BOOM

In the third part of the Jib Crane calculation software, you must enter the data related to the column base of the boom. This set provides the bending moment of the structure and the stability of the jib crane boom. In the following, you can see the tensions created in this collection.

## BOOM DATA JIB CRANE

A very important feature of the crane calculation software is that you can compare the boom box and boom beam at the same time. And choose the best type of canvas for your jib crane in terms of weight and cost. and compare the stresses and displacements of both. Therefore, enter the boom box data on the left side and the boom beam data on the right side.

## BASE PLATE DATA JIB

In this section, the data related to the concrete section that the base plate of the jib crane is on Enter it will be installed. Also, the data related to the base plate, what are its dimensions, how many anchor bolt holes does it have, and how far are the anchor bolts from each other. After entering these data, you will see in the next sections what the tensile force on the anchor bolts, the thickness of the base plate, and the dimensions of the jib crane base plate will be.

## DATA FOR SELECTION MOTOR

The part that has been recently added in the jib crane calculation software is related to the power and engine speed required for the lateral, rotational and lifting movement of the jib crane. You can enter data in this section. Data such as ambient temperature, altitude above sea level, type of engine control, etc.

## JIB DEFELECTION BOOM BOX CHECK

After entering the boom box or boom beam data, you can view the boom deflection value at the beginning, middle and end points, which is the worst possible case for jib crane deflection, and evaluate it according to the CMAA standard.

## JIB DEFELECTION BOOM BOX CHECK

In this section, according to the previous section, the deflection value for the beam is calculated. By looking at the final deflection in boom box and boom beam, you will see that the deflection value of the boom box of the jib crane is the lowest compared to the boom beam and the boom box can be used. But keep in mind that you may be affected by the cost of materials and construction conditions. Therefore, Pocket Crane’s calculation software is for you to choose the best mode by comparing the moment between boom box and boom beam, although both modes are acceptable in terms of their dimensions.

## JIB BOOM DIMENSION CHECK

At this stage, you can see the dimensions of the boom in terms of standard, the moment of inertia for the boom box and jib crane boom, the weight of the components and the entire jib crane.

## Calculate Base Column Boom Jib Crane

At this stage, the dimensions of the base Column boom are given according to the standard, which can be reached by changing these parameters in the described data entry steps. The tensions created in this collection are shown in 12 points. which reduced the tension as much as possible by changing the amplitudes and other parameters of this set.

## JIB BOOM DIMENSION CHECK

At this stage, you can see the dimensions of the boom in terms of standard, the moment of inertia for the boom box and jib crane boom, the weight of the components and the entire jib crane.

## Calculate Stress , Shear Stress for Boom Box and Boom Beam JIB Crane

In the two figures, the stress created in the boom box and boom beam jib crane modes is shown. which can be compared with others and by changing the sizes of the boom box and the boom beam of the jib crane, the most optimal mode can be obtained for the design of the jib crane boom.

## Calculation of Force and Torque of Jib Crane

In this section, you can also see the torque created in the crane pocket at different points of the structure. In this section, these calculations are given for the two modes of boom box and boom beam. So, as you can see, the purpose of the software is to calculate the moment of these two modes in order to have the best choice of canvas for the structure.

## Calculation Base Plate Jib Crane

At this stage, the calculated value of the base plate of the jib crane has been obtained from observing the results. You will finally get the thickness of the base plate, the dimensions of the base plate, etc.

## Calculation Anchor Bolt Jib Crane

The calculation of the acceptable anchor bolt tensile force against the bending moment of the crane jib, the number of anchor bolts, etc. is given.

## Calculation Column Jib Crane

This section is related to the calculations of the jib crane column. which will examine parameters such as horizontal and vertical stress on the column of the green jib, calculation of the torque applied to the column of the crane jib, calculation of the transverse surface involved with the column, etc. And at the end of the calculations of this section, we will reach the diameter and thickness of the jib crane column, which is shown in the figure.

## Calculation Column Jib Crane

And at the end of the Jib Crane calculation software, we reach the selection section of transverse, lifting and rotary motors. which will be determined according to the weight parameters and the working conditions of the structure and can be relied upon.
