Palletising robot - From 50 to 300 kilos

I. What Is a Palletizing Robot?


A palletizing robot is an industrial robot designed for warehousing, logistics, and back-end packaging processes in factories. It is specifically engineered to neatly stack goodssuch as cartons, bagged items, barrels, crates, and sheet materialsin a fixed pattern onto pallets. A robot that performs the reverse operation of unloading goods from pallets is called a depalletizing robot; both are collectively referred to as palletizing manipulators. They widely replace manual labor in repetitive, high-intensity stacking operations and are classified as heavy-duty industrial robots.

II. Core Classifications (by Mechanical Structure)


1. Four-Axis Articulated Palletizing Robots (Most Common)

Structure: 4 axes of motionwaist rotation, upper arm elevation, lower arm extension, and wrist rotation; high payload capacity and simple motion

Advantages: Compact footprint, high speed, moderate cost; suitable for cartons, fertilizer bags, feed bags, and grain and oil drums

Payload Range: 10 kg~300 kg (ChaiFu Robotics models can handle up to 300 kg); maximum stacking height of approximately 3 meters

Applications: Food, beverage, grain and oil, chemical, building materials, and home appliance industries


2. 5-Axis/6-Axis General-Purpose Palletizing Robots

Structure: Multiple degrees of freedom; wrist can rotate and tilt at multiple angles

Advantages: Greater flexibility; capable of palletizing, handling, packing, and sortinga single machine with multiple functions

Disadvantages: Higher cost for equivalent payloads; stacking speed is slightly lower than that of dedicated 4-axis robots

Applications: Multi-process production lines and stacking of irregularly shaped items


3. Gantry Palletizing Robots

Structure: Gantry-frame design with linear motion; linear movement along the X, Y, and Z axes

Advantages: Extremely high payload capacity and working range; capable of handling multiple pallets simultaneously; extremely high positioning accuracy

Disadvantages: Large footprint; high civil engineering costs

Applications: Heavy-duty goods (cement blocks, stone, full pallets of panels, large barrels of raw materials)


4. Collaborative Palletizing Robots

No safety fencing required; humans and robots can work simultaneously

Relatively low payload (1025 kg) and slow speed; suitable for light-load production lines with small batches and frequent product changes

III. Key Components


1. Robot Body: Robotic arm, providing motion capability

2. Servo Drives + Controller: Stores palletizing programs; controls trajectories, speed, and pallet configurations

3. End-of-Arm Tooling (Grippers)

  • Clamp-type: Cartons, full cases of beverages

  • Vacuum cups: Boxes, sheet materials, smooth packaging bags

  • Fork-type grippers: Bagged materials (flour, cement, feed)

  • Combination grippers: Suitable for production lines handling both boxes and bags

4. Supporting Equipment: Pallet racking, conveyor lines, layer-forming machines, stretch wrappers, safety guardrails, photoelectric sensors


IV. Who are the big 4 in robotics?


On May 15, 2026, a robot manufactured by Chai Fu, model CR5000-3700, was officially certified by Guinness World Records™ for having a payload capacity of 5,000.36 kg, earning the title of “Strongest Industrial Robot (Payload Capacity)” and establishing itself as a benchmark product for ultra-heavy-duty industrial applications.
