2000kg Heavy Duty Robotic Arm | 6-Axis SF2000-C4000

A two-tonne payload rating answers only one part of an automation brief. The production requirement is a complete handling sequence: secure the component, control its orientation, move it through the available space, and deliver it to the next operation.

The CHAIFU SF2000-C4000 heavy duty robotic arm combines a 2000kg payload capacity, 4000mm maximum reach, 6-axis articulation, and ±0.3mm repeatability. It is part of the ALPHTIC series of vertically articulated industrial robots.

For a proposed heavy-handling cell, evaluate the model against the entire task—not the workpiece weight alone. Tooling, load geometry, fixture access, production timing, and integration requirements should form a single application specification.

SF2000-C4000 Technical Specifications

These are manufacturer-published specifications. Confirm the current technical documentation, supplied configuration, and application-specific load limits before final equipment selection.

A 2-Tonne Industrial Robot for More Than Point-to-Point Lifting

The reason to evaluate a 6-axis industrial robot is often the need to change a component’s orientation while transferring it. Position and orientation are distinct parts of a robot’s pose; six-axis articulation provides flexibility to address both within the robot’s permitted motion range.

For the SF2000-C4000, begin by defining how the part must arrive at the next station. Does a housing need to be turned before entering a fixture? Must a fabricated assembly remain level? Is there only one direction from which the gripper can approach?

These requirements determine the motion study.

Consider a proposed transfer from an incoming cradle to a machine fixture. The application review should demonstrate gripping access, clearance above the cradle, rotation of the component, approach to the machine, and withdrawal after placement.

This is an illustrative application concept, not a claim of an existing installation. Its purpose is to define what the proposed robot cell must accomplish.

The value of six-axis motion lies in a verified handling sequence—not in the axis count alone.

How Much Can a 2000kg Heavy Duty Robotic Arm Actually Carry?

Calculate the Combined Wrist Load

Robot payload includes the end effector and the load it carries. The gripper, mounting adapter, tool changer, and other wrist-mounted equipment must therefore be included in the assessment. The applicable wrist moment and inertia limits must also be satisfied.

Use the following calculation for preliminary screening:

Combined wrist load = workpiece + gripper + adapters + other wrist-mounted equipment

The examples below illustrate why workpiece mass alone is insufficient.

These are hypothetical calculations, not approved SF2000-C4000 applications.

In the first example, the 100kg difference does not establish a sufficient operating margin. The tool-and-workpiece assembly still requires review of its center of gravity, moments, inertia, and intended movement.

Review Load Geometry Before Finalizing the Gripper

Heavy-robot manufacturers treat load inertia and wrist loading as important design and selection considerations alongside payload. A large component’s mass distribution can make its handling requirements substantially different from those of a compact component of similar weight.

For an SF2000-C4000 inquiry, provide the gripping location and the proposed tool drawing together with the workpiece data. Identify the heaviest product variant and the variant with the most demanding geometry; they may not be the same part.

Ask for the robot and gripper to be assessed together. Selecting the arm first and leaving the tooling concept unresolved makes the application harder to define accurately.

Planning a Workcell Around the 4000mm Reach

Maximum reach is a starting dimension, not a complete description of usable space. Industrial robot technical documentation distinguishes reach, joint travel, and operating-area dimensions because each affects access differently.

For the SF2000-C4000, use 4.0m as an initial layout reference, then evaluate the full tool and component geometry.

A useful motion study should check the approach to each fixture, the clearance required during rotation, and the space needed to release and withdraw the gripper. Include machine doors, support structures, nearby equipment, and any part overhang.

Do not approve a layout simply because its pickup and placement coordinates appear reachable. Require a demonstration of the connecting path in the required orientations.

For a machine-loading task, specify the insertion direction and depth. For palletizing, include the highest and farthest placement positions. For assembly transfer, show how the component enters the receiving fixture without interfering with locating features or clamps.

Applications to Evaluate for the SF2000-C4000

Heavy-payload industrial robots are used for material handling, machine tending, large-component transfer, and palletizing. These application categories are documented across established heavy-robot product ranges.

The following scenarios provide a framework for an SF2000-C4000 project review. Final suitability depends on the specific workpiece, tooling, motion, environment, and production requirements.

Large Castings and Machinery Components

Large castings and substantial manufacturing assemblies are established examples of heavy robotic handling. High-payload robot applications include transferring bulky castings to machine fixtures and handling oversized components.

For your proposed cell, describe how each part arrives: on a cradle, conveyor, pallet, or dedicated fixture. Identify acceptable gripping surfaces and any restrictions on contact with machined or finished areas.

Also specify dimensional and mass variation across the product family. Use these variations to define the tooling study and the representative parts for testing.

Heavy Machine Loading and Unloading

Machine tending is a documented application for heavy industrial robots. The task requires a handling solution that is compatible with the machine’s access and operating sequence.

For an SF2000-C4000 installation, provide the machine opening dimensions, fixture location, loading direction, and required insertion depth.

Define the handover between the robot and the machine. The application brief should state how the system will confirm that access is permitted, the component is secured, and the robot has cleared the enclosure before the next operation begins.

Fabricated Assemblies and Heavy Unit Loads

A proposed application may involve transferring a fabricated assembly into a downstream fixture or placing a heavy product onto a shipping support.

Specify exactly what the robot will carry. Include any pallet, carrier, or support frame that moves with the component.

Also distinguish between transporting the part and holding it while another process applies force. External forces require a separate load assessment; they are not automatically covered by a payload figure.

For stacking applications, provide the load arrangement, placement orientation, and maximum stack height. Where orientation changes are unnecessary, include a dedicated palletizing configuration in the options review rather than assuming that six axes are always preferable.

Understanding ±0.3mm Repeatability

The SF2000-C4000’s published repeatability is ±0.3mm.

Repeatability describes consistency when returning to a programmed position. It is different from absolute accuracy, which concerns the difference between an intended position and the position actually achieved. NIST identifies these as separate characteristics that affect a robot’s ability to meet manufacturing requirements.

Consequently, the repeatability specification should not be presented as a guarantee of finished-part tolerance, machining accuracy, or final placement accuracy in every installation.

For a fixture-loading project, define the required result at the receiving fixture. Agree on the workpiece, gripper, measurement reference, and operating conditions used for acceptance.

For a dimensionally demanding application, request verification of the installed system rather than relying on the robot specification alone. NIST also notes the importance of preparation, calibration-related considerations, and maintenance in achieving useful positioning performance.

Validate the Production Cycle, Not Just Robot Movement

Set the production target around the complete operation.

For an SF2000-C4000 proposal, request a cycle study that includes part confirmation, gripping, clearance movements, transfer, placement, release, and withdrawal. Include communication with fixtures and machines, along with any waiting time that affects output.

Identify which activities can overlap and which must occur sequentially. Ask the supplier to document the assumptions behind the proposed cycle time.

This application-based approach provides a measurable basis for acceptance. NIST’s manufacturing robotics work similarly emphasizes using application requirements to define performance metrics and verification methods.

A useful acceptance plan should establish:

Use representative product variants during testing, not only the easiest component in the range.

Define the Complete Automation Scope

Mechanical and Controls Integration

An industrial robot system includes the manipulator and associated equipment, such as the controller and end effector. Assessing the robot alone does not define the complete application.

For the proposed SF2000-C4000 cell, request a clear scope covering the robot package, gripper, fixtures, mounting arrangement, machine interfaces, and commissioning responsibilities.

Confirm the proposed communication interfaces and any required sensing functions. Ask which features are included, optional, or supplied by another integration partner.

Request the current foundation and installation requirements before approving the mounting location. Have the supporting structure reviewed by a qualified engineer using the manufacturer’s data.

Operating Conditions and Safeguarding

Provide the actual operating conditions, including temperature, dust, moisture, coolant exposure, and cleaning methods. Request confirmation that the proposed robot and tooling configuration is suitable.

Safety planning must address the complete application, including the robot, gripper, held load, associated machinery, and personnel access. The application risk assessment should determine the required protective measures.

Ask the system design to address load retention, guarded access, maintenance isolation, and recovery following a power interruption or gripping-system fault. Resolve these requirements during engineering, rather than treating them as additions after installation.

What to Include in a 2000kg Industrial Robot Quotation Request

For a meaningful quotation, define the task before requesting a price.

Send the workpiece drawing, mass, dimensions, gripping concept, pickup and placement locations, and required orientations. Include a factory layout and the target production cycle.

State whether the request covers the robot package or an integrated cell. Ask for an itemized proposal that separates tooling, fixtures, controls integration, safeguarding, installation, programming, commissioning, training, and documentation.

Also request confirmation of the supplied configuration, warranty terms, maintenance requirements, and spare-parts support.

For internal project evaluation, compare the proposal with your measured current process. Use actual handling times, production demand, and operating costs rather than assuming a fixed productivity increase or payback period.

Frequently Asked Questions

Can the SF2000-C4000 handle a 2000kg workpiece plus a gripper?

Not on the basis of its payload rating. The gripper and other wrist-mounted equipment contribute to the total load, and the complete assembly must meet the applicable loading limits.

Why evaluate a 6-axis heavy duty robotic arm?

Six-axis articulation is useful when the task requires changes in tool orientation as well as movement between locations. The required approach and placement angles should guide the selection.

Can this robot replace a crane or transfer device?

Evaluate that possibility against a defined task rather than assuming direct substitution. Ask the application study to compare the required travel, load geometry, orientation changes, production sequence, and access requirements.

What should a supplier demonstrate before the purchase is approved?

Request an agreed load assessment, motion study, integration scope, and acceptance plan. These deliverables should show how the proposed equipment will meet your specific production requirements.
