SZGH B2300-E-4 — 4-Axis Palletizing Robot for Medium-Heavy Carton & Box Stacking

What Is the SZGH B2300-E-4?

The SZGH B2300-E-4 is a four-axis industrial palletizing robot with a 50 kg payload capacity and a 2,300 mm working radius, purpose-built for medium-heavy carton, bag, and box palletizing on continuous packaging and export lines. Its simplified 4-axis kinematic structure delivers faster cycle times, lower maintenance overhead, and a lower total cost of ownership compared to six-axis alternatives in the same payload class.

Core Advantages

Dual-Pallet Coverage at 2,300 mm — B Series' Second-Longest Reach

At 2,300 mm, the B2300-E-4 covers wide dual-pallet palletizing layouts in a single robot cell without repositioning. This eliminates the need for conveyor extensions or secondary transfer equipment and reduces floor-space requirements by up to 30% versus two separate palletizing stations.

50 kg Payload Handles Two 20 kg Export Cartons Per Cycle

A 50 kg usable payload means the robot can pick two standard 20 kg export cartons simultaneously. Compared to a 25 kg-class robot cycling one box at a time, the B2300-E-4 doubles throughput per cycle — delivering 4–5× the palletizing speed of a trained manual operator over an eight-hour shift.

4-Axis Architecture: Faster, Simpler, Lower Maintenance Cost

Palletizing and box-stacking operations require only planar pick-and-place motion — no complex wrist reorientation is ever needed. The B2300-E-4's 4-joint kinematic chain achieves higher cycle speeds than equivalent 6-axis robots for this task class because fewer axes need to accelerate and decelerate per cycle. With two fewer joints, there are two fewer potential failure points, and factory-level maintenance (lubrication, encoder calibration) is straightforward for in-house technicians without specialized robotics training.

±0.2 mm Repeatability — Precision That Eliminates Pallet-Layer Collapse

For carton palletizing, stacking accuracy is the critical quality metric. A ±0.2 mm repeat position ensures every box lands within tolerance, producing tight, stable pallet layers that meet international shipping requirements and reduce compression-damage claims from overseas buyers.

CE and ISO 9001:2015 Certified — Export-Ready Out of the Box

The B2300-E-4 ships with full CE marking and ISO 9001:2015 quality system certification, satisfying European customs and end-customer compliance requirements without additional third-party testing delays for most markets.

Customer Case Study

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH) | May 2026

One of the cases I return to often when I explain the B2300-E-4 comes from a food export manufacturer in Thailand. They ship frozen food cartons — each weighing 20 kg — to European supermarket chains, and their palletizing specification is strict: layer height must be consistent, edge alignment must be within a few millimeters, and every pallet must survive the long-haul shipping journey without compression deformation.

When they came to us, they were running eight workers per shift on manual palletizing. The job was physically brutal — lifting 20 kg boxes repeatedly for eight hours in a cold-storage-adjacent packing hall — and by end of shift, worker fatigue was visible. More critically, inconsistent hand placement was causing misaligned layers, and their European customers were filing complaints about cartons arriving deformed under pallet pressure.

Their target was 3,000 boxes per shift. Their actual throughput with eight workers was barely hitting that number on a good day.

We deployed a single B2300-E-4 with a vision-guided gripper end-of-arm tool. The robot's 2,300 mm reach covered a full dual-pallet layout without any conveyor extension — both pallets sat within the robot's working envelope simultaneously. Placement deviation measured at ±3 mm per layer, well within the European shipper's tolerance.

The result: single-shift capacity rose from 3,000 cartons to 4,800 cartons — a 60% throughput increase. European customer complaints dropped to zero in the first three months post-installation. And the eight workers who had been doing that physically punishing job were transferred to packaging inspection roles — higher-skill, higher-value, much safer work.

The B2300-E-4 did not eliminate those jobs. It upgraded them. That is the outcome I want every deployment to deliver.

Control System & Integration

The SZGH B2300-E-4 is designed to integrate with the SZGH proprietary CNC motion controller — the same controller platform used across the full SZGH robot lineup, giving integrators and in-house engineers a consistent programming environment across multiple robot types on the same factory floor.

Frequently Asked Questions

Q1: Why choose a 4-axis palletizing robot instead of a 6-axis robot for carton stacking?

Palletizing is a planar pick-and-place task. Boxes and bags need to be moved from a conveyor to a pallet in a consistent orientation — they do not need the complex wrist reorientation that 6-axis robots provide for welding or assembly. A 4-axis robot executes this motion faster (fewer axes to accelerate per cycle), costs less to purchase, and has fewer mechanical components to maintain. For palletizing specifically, 4-axis is the correct tool for the job.

Q2: Can the B2300-E-4 handle a dual-pallet layout simultaneously?

Yes. The 2,300 mm working radius covers a standard dual-pallet layout (two 1,200 × 1,000 mm or 1,200 × 800 mm pallets side by side) within a single robot cell, allowing the robot to alternate between both pallets during one shift without repositioning or additional transfer equipment.

Q3: What is the cycle time for a 20 kg carton at full payload?

Actual cycle time depends on pick-to-place distance, pallet height, and EOAT weight. In a typical dual-pallet carton palletizing cell with a 1,500 mm average move distance, the B2300-E-4 achieves approximately 1,200–1,500 cycles per hour with a single-box gripper, or 600–800 cycles per hour with a two-box gripper (equivalent to 1,200–1,600 boxes/hour throughput).

Q4: Does the ±0.2 mm repeatability meet export pallet stacking standards?

Yes. Export pallet standards (including ISPM-15 and European retailer stacking specifications) require layer-to-layer alignment within ±5–10 mm. The B2300-E-4's ±0.2 mm mechanical repeatability, combined with vision guidance, achieves placement accuracy well within those tolerances and eliminates compression-damage claims caused by misaligned layers.

Q5: What end-of-arm tooling is compatible with the B2300-E-4?

The robot's tool flange accepts standard and custom EOAT including vacuum cup arrays (for corrugated cartons), mechanical clamp grippers (for rigid boxes, pails, and drums), and bag-clamp grippers (for flexible sacks). SZGH's application engineering team provides EOAT selection and custom design services at no additional consultation cost with a robot order.

Q6: How long does installation and commissioning take?

For a standard single-robot palletizing cell with SZGH-supplied conveyor and pallet dispenser, installation and commissioning typically takes 3–5 business days on-site by a qualified SZGH technician or authorized local distributor. Remote commissioning support is available via the controller's network interface.

Q7: Does the B2300-E-4 ship with CE documentation included?

Yes. CE Declaration of Conformity and technical documentation package is included with every export shipment. No additional third-party CE testing is required for import into EU/EEA countries.

Q8: What is the difference between the B2300-E-4 and the B2100-F-4?

The B2300-E-4 offers a longer reach (2,300 mm vs. 2,100 mm) and is optimized for 50 kg medium-heavy payloads, making it ideal for dual-pallet carton layouts. The B2100-F-4 handles heavier 100 kg payloads at a slightly shorter reach, suited for heavy pails, drums, and high-density carton stacks. Choose B2300-E-4 for reach and coverage; choose B2100-F-4 for maximum single-pick weight.
