How to Read an Electric Pallet Truck Load Capacity Chart

From “Rated Load” to “Actual Capacity” – The Safety Logic Behind a Single Chart

In an electric pallet truck‘s specification table, rated load is usually the most prominent figure. Many operators and procurement staff see “2000kg” and assume the equipment can handle 2 tons anytime — but this is precisely the biggest misunderstanding.

An electric pallet truck‘s actual load capacity is not a fixed value. It changes dynamically with load centre and lift height. A proper load capacity chart is the core tool that reveals this dynamic relationship. Reading it correctly is not just about equipment selection — it directly relates to operational safety.

1. Why Does Load Capacity “Change”?

1.1 Rated Load Is Not a Fixed Value

“Rated load 2000kg” is only the maximum capacity under standard operating conditions. Once actual conditions deviate from the standard, safe capacity decreases.

Two core variables affecting load capacity:

• Load Centre: The horizontal distance from the vertical face of the forks to the load‘s centre of gravity

• Lift Height: The vertical distance the load is raised

1.2 Physical Principle: Centre of Gravity Shift Causes Tip-Over Risk

The stability of an electric pallet truck depends on the stability triangle — the support area formed by two front wheels and one rear axle pivot. When the load is raised or its centre of gravity moves away from the fork heel, the combined centre of gravity shifts toward the boundary of this support area. Once it extends beyond the triangle, tip-over risk increases dramatically.

2. Three Core Elements of a Load Capacity Chart

A standard load capacity chart is typically presented as a table containing three key pieces of information.

2.1 Load Centre

Load centre is the horizontal distance from the vertical face of the forks to the load’s centre of gravity, usually expressed in millimetres (mm). Industry standard load centres are typically 500mm or 600mm.

Key Rule: The larger the load centre, the lower the equipment‘s safe load capacity.

For example: a truck rated “2000kg @ 600mm load centre” will have a safe capacity significantly below 2000kg when the load’s centre of gravity reaches 800mm from the fork face.

2.2 Lift Height

Lift height is the vertical distance the load is raised. Load capacity charts typically use rows to represent different lift heights.

Key Rule: The higher the lift, the lower the safe load capacity.

For example, a forklift with a maximum allowable load of 3,803 lb at 146“ lift height drops to 3,362 lb at 256” lift height.

2.3 Cross-Data: Actual Load Capacity

Each cell in the chart shows the maximum safe load for a specific combination of lift height and load centre.

How to Read:

• Row: Select the actual lift height

• Column: Select the actual load centre

• Intersection: The maximum safe load for that condition

3. How to Read a Load Capacity Chart Correctly

3.1 Step-by-Step Reading Method

According to Linde Material Handling‘s technical guide, correct reading follows these steps:

Step 1: Locate the load capacity chart on the equipment nameplate or data plate
Step 2: Confirm the standard load centre stated on the chart (e.g., 600mm)
Step 3: Measure the actual load’s centre of gravity position
Step 4: Confirm the actual lift height
Step 5: Find the intersection of the corresponding row and column, read the safe load
Step 6: If the actual load centre doesn‘t match the chart value, always choose the more conservative (lower) capacity

3.2 Common Misreadings and Risks

4. Interpreting CBDE’s Load Capacity Parameters

Take Diding Lift‘s 2T Stand On Pallet Truck Off Road CBDE as an example. Its rated load is 2000kg, with a standard load centre of 600mm.

4.1 Capacity Under Standard Conditions

4.2 Factors Affecting Load Capacity

The CBDE‘s solid structural design with high stability has been specifically optimized for 2-ton heavy loads, ensuring stable capacity at the standard load centre. Its off-road tires and reinforced chassis maintain stable load performance on outdoor uneven surfaces.

It should be noted that if the load’s centre of gravity exceeds the 600mm standard load centre, the CBDE‘s safe load capacity will decrease accordingly — a physical principle shared by all electric pallet trucks.

5. The Relationship Between Load Charts and Safe Operation

5.1 Safety Margin Principle

Even if the load weight is within the chart’s allowable range, it is still recommended to reserve a 10%-20% safety margin. Reasons include:

• Possible measurement error in load centre

• Surface conditions (slopes, wet surfaces) reduce stability

• Equipment wear (e.g., hydraulic system aging) may affect capacity

5.2 Consequences of Overloading

Overloading not only increases tip-over risk but also causes:

• Mast deformation, fork bending

• Hydraulic system overload damage

• Extended braking distance

• Reduced equipment lifespan

6. Summary

Reading an electric pallet truck load capacity chart correctly hinges on understanding how “load centre” and “lift height” dynamically affect safe capacity. Rated load is only the maximum under standard conditions; in actual operations, the safe load must be looked up in the chart based on the actual load centre of gravity position and lift height.
