Training Objectives

Explain how load height affects forklift stability
Apply practices to maintain stability when lifting loads

Course Overview

While the Stability Triangle explains forklift balance on a flat surface, real-world operation also involves height. This three-dimensional concept is known as the Stability Pyramid. It helps operators understand how raising or lowering a load changes the overall balance of the forklift system.

In this model, the combined center of gravity of the forklift and its load can be imagined as a point suspended within a pyramid-shaped boundary. When the load is kept low, the pyramid remains wide and stable, helping keep the center of gravity securely within safe limits.

However, as the load is raised higher, the pyramid becomes taller and narrower. This reduces the margin for stability and makes it easier for the center of gravity to move outside the safe zone, which can lead to a tip-over. To reduce this risk, operators should always keep loads as low as possible, especially while traveling.

No Worries. Here’s Some Helpful Info.

What is the Stability Pyramid?


The Stability Pyramid is a three-dimensional model that explains how load height affects forklift balance and stability.


Why does raising a load reduce forklift stability?


Raising the load makes the stability zone narrower, increasing the chance that the center of gravity will shift outside safe limits.


Why should loads be kept low while traveling?


Keeping loads low maintains a wider stability base and reduces the risk of tipping the forklift.


What role does the center of gravity play in the Stability Pyramid?


The center of gravity represents the balance point of the forklift and load, which must remain within the stability zone.


How can operators reduce the risk of forklift tip-overs?


Operators should keep loads low, avoid sudden movements, and follow proper load-handling procedures.
