Heavy Duty Robotic Arm: 800kg SF800-C2850 | CHAIFU
2026-10-10
Moving a heavy component through a production line requires more than lifting capacity. The robot must also reach the loading position, maintain the required workpiece orientation and operate within the constraints of the surrounding equipment.
The CHAIFU SF800-C2850 heavy duty robotic arm combines an 800kg payload capacity with a 2850mm reach. Part of the ALPHTIC series, this six-axis industrial robot provides a platform to evaluate for heavy component transfer, machine loading and unloading, palletizing and workpiece positioning. CHAIFU's published model information identifies a vertically articulated configuration and ±0.1mm repeatability.

What Is a Heavy Duty Robotic Arm?
A heavy duty robotic arm is a programmable industrial manipulator used to move and position substantial workpieces, tooling or assembled loads. Applications can include transferring metal components, loading production equipment and positioning parts for subsequent operations. Industrial robots combine a mechanical arm, a controller and application-specific tooling to perform programmed tasks.
For purchasing decisions, the term "heavy duty" is only a starting point. The useful question is whether the robot's permitted payload, wrist loading and working envelope match the actual process. Manufacturers of large industrial robots therefore publish more than a lifting figure: their technical information also addresses reach, wrist torque, inertia and application conditions.
For the SF800-C2850, begin with the 800kg payload and 2850mm reach, then evaluate the complete tool-and-workpiece combination.
Understanding the 800kg Payload: Include the Gripper and Tooling
An 800kg industrial robot should not be selected on workpiece weight alone. Wrist payload includes the end effector and the load it carries. Adapters, tool changers and other wrist-mounted equipment must also be included in the mass assessment. Permitted wrist moments and inertia remain separate constraints.
A useful preliminary calculation is:
Total wrist load = workpiece + gripper + adapter or tool changer + other wrist-mounted equipment
Consider this illustrative example:
| Load component | Example mass |
Workpiece | 600kg |
Gripper | 150kg |
Adapter and wrist-mounted accessories | 20kg |
Total wrist load | 770kg |
The combined mass is 30kg below an 800kg rating. However, that difference does not establish that the application is approved.
A large tool may position the combined center of gravity farther from the mounting flange. A wide or elongated workpiece may also create substantial rotational inertia. These conditions must be checked against the robot's permitted load data, even when the total mass is below the stated payload capacity.
For the SF800-C2850, submit the proposed tooling arrangement and load geometry for review before treating the payload calculation as a final selection.
How the 2850mm Reach Affects Workcell Layout
The SF800-C2850 has a specified reach of 2850mm, or 2.85m. Use this dimension as an initial layout reference—not as proof that every point within a 2.85m radius is accessible in every orientation.
Robot selection also requires an understanding of the working envelope, joint movement and tool orientation. Manufacturer technical pages distinguish maximum reach from detailed operating areas for this reason.
For your proposed cell, check the complete sequence: approach the part, engage the gripper, lift clear of the fixture, transfer the load, place it and retract. Include the tool and workpiece in the clearance study rather than checking the bare robot arm alone.
Pay particular attention to machine doors, fixture heights, conveyor edges and the highest or deepest placement position. A layout that works for an empty pallet, for example, still needs verification at the final stack height.
Selection tip: Ask for a working-envelope review using your actual layout and load dimensions. Do not finalize the robot position from the maximum-reach figure alone.
Applications to Evaluate for the SF800-C2850
CHAIFU identifies handling, machine loading and unloading, assembly and palletizing among the ALPHTIC series’ application areas. The following are candidate uses for application engineering; suitability depends on the specific load, tooling, environment and motion sequence.
Heavy Component Transfer
Heavy-duty material handling can involve castings, machinery housings, fabricated structures and other large production components. Comparable high-payload robot platforms are used for loading, unloading and transferring heavy parts in metalworking, automotive and construction-related manufacturing.
For an SF800-C2850 project, identify the pickup and placement conditions first. Is the part consistently located? Does its orientation change? Are its gripping surfaces accessible? Provide these details alongside the component's mass and dimensions.
This turns a general request for an "800kg robot" into a defined transfer task that can be assessed.
Machine Loading and Unloading
A robotic machine-tending application must connect the handling sequence with the production machine. Heavy-payload manufacturers identify machine tending as a core application, but the robot is only one element of the resulting system.
For the SF800-C2850, describe the machine opening, fixture location, loading direction and available installation space. Also specify how the system should confirm that the machine is ready, the part is secured and the robot has cleared the operating area.
Where the workpiece is hot, wet or contaminated, include those conditions in the application review rather than assuming that the standard configuration is suitable.
Heavy-Duty Palletizing and Depalletizing
Heavy-duty palletizing may involve substantial individual products, grouped loads or complete layers. High-payload industrial robot applications include full-layer palletizing and the handling of bulky production loads.
When evaluating the SF800-C2850 as a heavy-duty palletizing robot, consider the combined load being lifted—not just the weight of one product. Include the layer gripper, any supporting structure and a pallet when the pallet is lifted with the goods.
Provide the pallet dimensions, stacking pattern, maximum stack height and target production rate. These details allow the review to address both load capacity and access to the required placement positions.
Large-Part Assembly and Fixture Positioning
Six-axis industrial robots can be used for assembly and handling applications that require controlled workpiece orientation. Manufacturer offerings in this category pair articulated motion with application-specific tooling and, where required, auxiliary equipment.
For an SF800-C2850 assembly project, define the orientation needed at each step and the tolerances required at the receiving fixture. Also identify whether the robot only transports the component or must hold it while another process acts on it.
Transporting a part and resisting process forces are different application requirements. Include both in the engineering specification when applicable.
Repeatability, Tooling and Environmental Conditions
Interpret the Repeatability Figure Correctly
CHAIFU lists ±0.1mm repeatability for the SF800-C2850. This should not be presented as a guarantee of ±0.1mm absolute positioning accuracy, machining accuracy or finished-part tolerance.
Repeatability concerns returning to a previously reached position; accuracy concerns how closely the robot reaches the intended position. A robot can be highly repeatable without having the same level of absolute accuracy.
For your application, specify the required placement or process tolerance separately. Include the fixture arrangement and calibration requirements in the discussion.
Confirm the Required Environmental Configuration
The published protection ratings are IP65 for the base axes and IP67 for the wrist axes.
Before ordering, provide the actual operating conditions: ambient temperature, dust exposure, coolant contact, cleaning procedures and any unusual contamination. Treat environmental suitability as a configuration question. Other industrial robot manufacturers similarly distinguish standard models from foundry, hygienic and other specialized environmental versions.
From Robot Arm to Complete Automation Cell
A production-ready system includes more than the manipulator. The end effector, fixtures, controls, sensors and interfaces must work together with the robot to perform the application.
When discussing an SF800-C2850 installation, ask CHAIFU to confirm the proposed scope in three areas:
Mechanical integration: gripper, mounting arrangement, fixtures, load presentation and maintenance access.
Controls integration: controller configuration, machine communication, input/output requirements and any requested sensing options.
Commissioning and support: programming scope, acceptance testing, operator training, documentation and spare-parts requirements.
Safety should be addressed during design, not added after the layout is fixed. The application risk assessment should determine the appropriate safeguarding, access controls and protective measures for operation and maintenance. Do not assume that an industrial arm is suitable for unguarded operation near personnel.
How to Request a Heavy Duty Robotic Arm Quotation
For a useful heavy duty robotic arm quotation, request an itemized proposal based on a defined task.
State whether you need the robot package alone or a broader automation scope. Ask the quotation to identify the controller and pendant, tooling, mounting equipment, controls integration, safeguarding, programming and commissioning items that are included or excluded.
Also request the current load diagrams, working-envelope information and installation requirements for the proposed configuration.
For the SF800-C2850, a practical inquiry should contain the workpiece mass and dimensions, estimated tooling mass, pickup and placement locations, required cycle time and operating environment. Drawings, layout files or photographs can help explain constraints that are difficult to describe in text.

Frequently Asked Questions
Can the SF800-C2850 handle an 800kg workpiece?
Do not assume so when additional tooling is required. The combined wrist-mounted load must be evaluated, including the workpiece and gripper. The load's center of gravity, moment and inertia must also remain within the permitted limits.
Is the SF800-C2850 a six-axis robot?
Yes. CHAIFU's published parameter table identifies the SF800-C2850 as a six-axis, vertically articulated industrial robot with an 800kg payload and 2850mm reach.
Can this model be considered for heavy-duty palletizing?
Yes, palletizing is an application area to evaluate. Confirm the combined gripper-and-product load, pallet layout, stacking height and required motion before selecting the final system. CHAIFU includes palletizing among the ALPHTIC series' applications.
When should a different robot configuration be considered?
Request an alternative when the proposed task exceeds the approved load limits, requires additional reach or cannot achieve the necessary orientation and clearance. Changing the gripper or layout may also be worth evaluating before choosing a larger robot.
What information should accompany an application inquiry?
Provide the part drawing, mass, dimensions, tooling concept, cell layout, target cycle time and operating conditions. Clearly identify whether the task involves transfer only, stacking, machine loading or holding a part during another process.
