Navigating the world of heavy-lifting machinery can be challenging. However, understanding the calculations behind these machines can simplify things significantly. In this blog post, we focus on wall-mounted jib crane calculations and how to perform these efficiently to ensure safe operation.


A wall-mounted jib crane is a type of crane used for lifting or lowering heavy materials. Mounted onto the wall, it provides a versatile solution for moving objects within a specific radius. Understanding its calculations is crucial for determining the crane’s safe working load, maximum load moment, bending moment, deflection, and stress levels.

Detailed Explanation of the Calculator’s Working

Our wall-mounted jib crane calculator simplifies complex calculations, making your job easier. You simply input the necessary parameters, including load weight, load distance, and others. The calculator then computes the load moment, bending moment, deflection, and stress based on these inputs.

Formula and Variables Description

The formulas involved in these calculations include:

  1. Load Moment = Load Weight x Load Distance
  2. Bending Moment = Load Moment
  3. Deflection = (5 x Load Moment x Length^3) / (384 x Modulus of Elasticity x Moment of Inertia)
  4. Stress = (Bending Moment x Distance from Neutral Axis) / Moment of Inertia

Each variable plays a critical role in determining the safe operation of the jib crane.


Consider a wall-mounted jib crane with a load weight of 1000 kg at a distance of 10 m. Assuming the length of the crane is 10 m, the Modulus of Elasticity is 200 GPa, the Moment of Inertia is 0.02 m^4, and the Distance from Neutral Axis is 0.1 m, our calculator would display the bending moment, deflection, and stress.

Industrial Use

In the industrial sector, jib cranes are used for assembly lines, loading or unloading of materials, and warehousing.


In construction, they help in lifting heavy materials such as steel, concrete, or large tools.

Most Common FAQs

What is the maximum load capacity of a jib crane?

The maximum load capacity or Safe Working Load (SWL) of a jib crane is defined by the crane manufacturer or based on engineering calculations. It ensures that the crane is used within its design limits.

Why are deflection and stress calculations important?

Deflection refers to the crane’s bending or sagging under load. It’s crucial to maintain deflection within acceptable limits to prevent structural failure. Stress calculation helps understand if the crane can handle expected stress levels without deformation or failure.
