2 Ton Electric Pallet Stacker Specifications & Dimensions

When selecting an Electric Pallet Stacker, specifications and dimensions are the fundamental parameters that determine whether the equipment can fit your warehouse space, aisle width, and operational requirements. Many buyers focus only on rated capacity and lift height, overlooking critical metrics such as mast lowered height, turning radius, aisle width, and fork dimensions—parameters that directly affect whether the equipment can enter your existing facility, maneuver between racks, and accommodate your pallet types. This guide provides a systematic breakdown of key specifications for 2-ton electric pallet stackers, helping you establish a complete dimensional framework.

1. Core Specifications at a Glance

Taking Diding Lift's 2T Electric Walkie Pallet Stacker CDDA as an example, the core specifications cover a complete parameter system from load capacity to battery configuration.

2. Mast and Lift Dimensions

Mast dimensions are critical parameters determining whether the equipment can fit your warehouse's vertical space. Different mast configurations correspond to different lowered and extended heights, directly affecting equipment passability and stacking height.

2.1 Mast Configuration and Dimension Mapping

2.2 Practical Impact of Mast Lowered Height

Mast lowered height is the equipment's "retracted" height, determining whether it can pass through vertical space constraints such as warehouse doors, elevators, and fire exits. For example, the CDDA20's duplex mast max configuration has a lowered height of 2330mm, meaning the equipment requires a clear door height of ≥2330mm. If your warehouse door height or elevator interior height is lower than this, choose a mast configuration with a lower retracted height (e.g., 1830mm for the duplex standard).

2.3 Load Capacity Limits at High-Level Stacking

At 3500mm lift height, the residual capacity is 1100kg. This means if your cargo weight exceeds 1100kg and needs to be stacked at 3.5 meters, the CDDA20 cannot safely handle it. Consider a stand-on model or larger tonnage equipment. Always check the load capacity chart for high-level stacking rather than directly applying the ground-level rated capacity.

3. Aisle Width and Turning Radius

This is the most overlooked yet critical space parameter. The CDDA20's minimum turning radius is 1494mm, which is excellent among 2-ton class walkie stackers.

3.1 Selection Significance of Turning Radius

Turning radius determines the equipment's maneuverability in confined spaces such as between racks, on loading docks, and at elevator entrances. Smaller values mean greater agility in tight spaces, reducing the risk of collisions caused by insufficient turning space. The CDDA20's 1494mm turning radius is excellent among 2-ton class walkie stackers.

3.2 Aisle Width Calculation Logic

The required aisle width (Ast value) is determined by the turning radius and pallet size together. For the CDDA20, the aisle width for 1200×1000mm pallets (width-wise entry) is 2377mm, and for 800×1200mm pallets (length-wise entry) it is 2307mm. This means that if your warehouse aisle width is ≥2377mm, the CDDA20 can perform right-angle stacking smoothly. For narrower aisles, consider the 800×1200mm pallet entry method or choose a model with an even smaller turning radius.

3.3 How to Measure Aisle Width

We recommend the following practical measurement method:

• Mark the start and end points at both ends of the rack aisle, and measure the narrowest point with a tape measure.

• Take the average of three measurements, and subtract space occupied by rack protrusions, columns, etc.

• Compare the measured value against the equipment's Ast value (e.g., 2377mm) and add a 100-150mm safety margin to accommodate operational tolerances.

Overall width 850mm determines rack-to-rack clearance and two-way traffic capability. Compared to same-tonnage models (Rebot CDD20 at 850mm, KION Baoli ES16 at 957mm, Longgong CPD20 at 940mm), the CDDA20's overall width is competitive, reducing collision risk in dense rack layouts.

4. Fork Dimensions and Pallet Compatibility

Fork dimensions directly affect whether the equipment can accommodate your pallet types and cargo specifications.

Standard Configuration: Fork size is 55×165×1150mm (thickness×width×length), fitting standard 1200×1000mm / 1200×800mm pallets. Fork outer width is adjustable to 550 or 685mm, adapting to different pallet widths (EUR or CP pallets). Fork lowered height is 86mm—if the pallet bottom clearance is limited (e.g., bottom boards or foam blocks), verify whether the forks can enter smoothly.

4.1 Common Pitfalls with Load Centre Distance

The 500mm load centre distance corresponds to standard EUR pallets (1200×1000mm). For non-standard pallets (e.g., 1300×1100mm) or off-centre loads (e.g., heavy cargo placed forward), actual capacity will decrease. Always check the load capacity chart against your actual load centre distance rather than directly applying the rated capacity.

4.2 Customisation Solutions

Fork length is fixed at 1150mm. For pallets exceeding 1200mm in length (e.g., certain appliance pallets) or double-face pallets (with bottom cross boards), consult the manufacturer for custom fork lengths or consider wide-leg models.

5. Weight and Battery

Service Weight (incl. battery) : The CDDA20 weighs 525-690kg (varies by mast configuration), which is moderate-to-light among comparable equipment, helping reduce floor loading requirements and improve maneuverability.

Battery Configuration: Standard 24V/82Ah maintenance-free gel battery supports single or multi-shift operations. Optional lithium upgrade—lithium batteries support fast charging (1-2 hours) for multi-shift high-intensity operations.

Motor Configuration: The CDDA20 is equipped with a 0.9kW AC drive motor and a 2.2kW AC lifting motor. AC motors consume less energy and have longer maintenance intervals (no carbon brush replacement) than DC motors, ideal for frequent start-stop stacking operations.

6. Comparison: CDDA20 vs. Other 2-Ton Class Models

To more clearly assess the CDDA20's market positioning, it is compared below with three representative same-tonnage models:

6.1 Narrow-Aisle Adaptability Comparison

The CDDA20's 1494mm turning radius is excellent among 2-ton walkie stackers. Compared to stand-on models, its advantage is particularly clear: Longgong CPD20's turning radius is 1900mm, and Rebot CDD20's is 1640mm. This means in aisles under 2.5 meters, the CDDA20 can complete right-angle stacking smoothly, while stand-on models may struggle to turn or require wider aisle space.

The 850mm overall width is another advantage of the CDDA20. Compared to KION Baoli ES16's 957mm and Longgong CPD20's 940mm, the CDDA20 navigates dense rack layouts more smoothly, requiring less space for two-way traffic—suitable for older warehouses or dense storage scenarios.

6.2 High-Level Stacking Capability Comparison

Stand-on models have clear advantages in high-level stacking. Longgong CPD20 reaches a maximum lift height of 6000mm, Rebot CDD20 can be configured to 5500mm, while the CDDA20's duplex mast max configuration is 3500mm. This means that if your rack height exceeds 3.5 meters, the CDDA20 cannot handle it—you would need to consider stand-on or larger tonnage models.

However, high-level stacking capability and aisle adaptability often involve trade-offs. Stand-on models, despite higher lift heights, have larger turning radii and overall widths, requiring wider aisles. If your warehouse aisle width is ≤2.5 meters and rack height is ≤3.5 meters, the CDDA20 is the better fit. If aisles are wider (≥3 meters) and high-level stacking is required, stand-on models offer greater advantages.

6.3 Comprehensive Selection Recommendations

Based on the above comparison, the CDDA20's core competitiveness lies in the balance between narrow-aisle adaptability and mid-to-low-level stacking efficiency. Its 1494mm turning radius, 850mm overall width, and 2377mm aisle width requirement give it a clear advantage in space-constrained warehouses. For scenarios requiring stacking above 4.5 meters with adequate aisle width, stand-on models such as Longgong CPD20 or Rebot CDD20 are more suitable.

7. Conclusion and Action Recommendations

Selecting the right 2-ton Electric Pallet Stacker specifications and dimensions comes down to "measure your space first, then match the parameters." Before contacting suppliers, complete the following three measurements:

1. Measure your warehouse's narrowest aisle → Compare against the equipment's Ast value (e.g., CDDA20's 2377mm) to ensure fit and reserve safety margin.

2. Measure the tallest rack level + 100-200mm margin → Determine required lift height and mast configuration.

3. Confirm your pallet type and dimensions → Verify load centre distance and fork dimensions match.
