2 Ton Electric Pallet Stacker: Load Capacity and Lift Height Chart

When selecting an Electric Pallet Stacker, the relationship between load capacity and lift height is one of the most easily misinterpreted parameter sets. Many buyers assume that a "2-ton stacker" can handle 2 tons at any height—but in reality, rated capacity only holds at low heights, and residual capacity progressively decreases as lift height increases. Taking Diding Lift's 2T Electric Walkie Pallet Stacker CDDA as an example, its 2000kg rated capacity drops to 1100kg at a lift height of 3500mm. This guide uses this product as a reference to systematically present the load capacity and lift height relationship for 2-ton electric pallet stackers.

1. Rated Capacity vs. Residual Capacity

Before interpreting the load capacity and lift height chart, it is essential to distinguish two core concepts.

Rated Capacity is the maximum load the equipment can safely lift at a standard load centre distance (typically 500mm) with the forks approximately 200mm above ground. This is the nominal value on the specification sheet and the baseline reference for selection.

Residual Capacity is the maximum load the equipment can actually safely lift at a specific lift height. This value decreases as lift height increases and is the true basis for high-level stacking scenarios.

Core Principle: Residual capacity is always less than or equal to rated capacity. The CDDA's rated capacity is 2000kg, but at 3500mm height, residual capacity is only 1100kg—meaning if you need to stack 1800kg at 3.5 meters, this model is not suitable.

2. CDDA Load Capacity & Lift Height Chart

The following table shows the load capacity corresponding to different lift heights for Diding Lift's 2T Electric Walkie Pallet Stacker CDDA (load centre 500mm):

Data based on CDDA20 product specifications and publicly available load curves. Actual values may vary slightly by mast configuration and battery condition.

Key Takeaways:

• Below 1600mm: Residual capacity equals rated capacity at 2000kg—full-load operation is safe in this range.

• 2000-3000mm: Residual capacity progressively decreases, from approximately 1800kg at 2000mm to 1300kg at 3000mm. Verify against actual cargo weight in this range.

• 3500mm: Residual capacity drops to 1100kg—nearly half the rated capacity. If cargo weight exceeds 1100kg and needs to be stacked at 3.5 meters, the CDDA cannot handle it.

3. Load Centre Distance Correction

The above chart assumes a 500mm load centre distance (standard EUR pallet 1200×1000mm). If your pallet specifications or cargo centre of gravity differ, actual load capacity requires correction.

Correction Logic: For every 100mm increase in load centre distance, load capacity decreases by approximately 10%-15%. If your load centre distance is 600mm, the CDDA's residual capacity at 3500mm may drop to approximately 950-1000kg. Always request the load capacity curve corresponding to your actual load centre distance from the supplier.

4. Lift Height and Capacity by Mast Configuration

The CDDA offers simplex and duplex mast configurations, with different lift heights and residual capacity at height.

Selection Tips:

• For rack heights ≤1600mm, simplex mast is sufficient with the strongest load capacity (2000kg throughout).

• For rack heights of 2000-3000mm, duplex standard or high configurations cover the range, with residual capacity of 1300-1800kg at height.

• For rack heights reaching 3500mm, choose the duplex max configuration and verify that residual capacity at height covers your cargo weight.

5. Load Capacity Comparison with Same-Tonnage Models

To more clearly assess the CDDA's load performance, it is compared below with three representative same-tonnage models:

Comparison Summary: The CDDA's residual capacity at 3500mm is approximately 1100kg, within the reasonable range for its class. Stand-on models (e.g., Longgong CPD20) offer slightly better high-level stability due to heavier chassis and wider stance, but their turning radius and overall width are also larger, requiring wider aisles. The CDDA's advantage lies in the balance between narrow-aisle adaptability and mid-to-low-level load capacity.

7. Conclusion and Action Recommendations

The load capacity of a 2-ton Electric Pallet Stacker is not a fixed value—it is a dynamic range that varies with lift height. Taking Diding Lift's CDDA as an example, its rated capacity of 2000kg only holds below 1600mm, dropping to 1100kg at 3500mm. The core of selection is first confirming the maximum stacking height and corresponding cargo weight, then checking the load capacity and lift height chart, and finally selecting the matching model.

Choosing a reliable manufacturer is equally critical. Diding Lift has 12 years of experience and a 65,000 m² factory & workshop, with products holding Europe EN & ISO, CE, EU Certificates, and supports ODM/OEM cooperation & customization. Its 2T Electric Walkie Pallet Stacker CDDA, featuring a 2000kg rated capacity, 3500mm maximum lift height, 1494mm turning radius, and AC motor system, provides a mature load solution for indoor narrow-aisle mid-to-low-level stacking scenarios.
