The forklift stability triangle is a defined, three-point area of support that calculates your forklift’s centre of gravity and stops it from tipping. The most common and severe type of forklift accident is overturning, which occurs due to carrying unbalanced goods, driving on uneven surfaces and operating unsafely. So, considering your forklift’s stability before operation is essential to avoid incidents.
What are the Three Points of a Forklift That Make up the Stability Triangle?
The forklift stability triangle is the three points of contact your forklift makes with the ground – the front left and right wheels, and the pivot point of the rear axle. These points contain the centre of gravity to achieve balance and prevent tip-overs. Understanding these crucial areas will dictate how to distribute your load and forklift weight.
What Factors can Affect the Forklift Centre of Gravity and Stability?
The position and weight of your load, turning and driving speed, the ground’s surface and forklift attachments can all affect your forklift’s centre of gravity and stability.
- Load Weight and Position: A heavy or uncentered load will put pressure on your forklift. The higher the raised load, the higher the combined centre of gravity and the more unstable your forklift will be.
- Speed and Turning: Turning sharply or at high speeds will push the combined centre of gravity outside the side boundaries through centrifugal force.
- Ground Surface: Driving on uneven terrain, over obstacles or on slopes will shift your forklift’s centre of gravity.
Attachments: Installing attachments to your forklift will change its weight distribution and stability ratings. Adjustments that impact the centre of gravity and overall volume of your forklift will require a new data plate to ensure safety post-installation.
What is Longitudinal Stability in Forklifts?
Longitudinal stability concerning forklifts refers to the balance between the weights of the forklift and the load when moving forward or backward. The longitudinal stability line is a crucial element of the stability triangle, running from the pivot point of the rear axle to the front wheels.
What is Lateral Stability in Forklifts?
Lateral stability concerning forklifts refers to the balance between the sides. The key to lateral stability is the line between the front wheels, which prevents the forklift from tipping sideways when operating. The weight of the load only minimally impacts your forklift’s lateral stability. The behaviour of your driver, the terrain and the position of your load dictate lateral instability.
Is There a Forklift Stability Triangle Calculation?
To calculate the stability of a load when lifted, you can use the formula:
Actual Capacity = (Rated Load Centre / Actual Load Centre) x Rated Capacity.
This calculation determines the maximum weight your forklift can safely carry.
- The “rated” load centre and capacity data is located on your forklift’s data plate.
- The “load” data is the distance from the back of the forks to the centre of the load.
Forklift Stability Essentials – How to Safely Carry a Forklift Load
Maintaining a forklift’s stability triangle is all about safe driving and considering data. Your forklift’s data plate will provide all the information you need to ensure it will remain stable while lifting and manoeuvring heavy loads. But the onus is on your drivers to ensure they drive slowly, smoothly and on level surfaces, especially when turning.
You must ensure each load is centralised and secured before moving, and keep the load low to the ground when you do. This will keep the chances of tipping minimal and lateral stability at a maximum.
