Gripper Sizing — Payload + CG Envelope Check
Holding-force and sizing math for a payload + cg envelope check including acceleration and safety factor.
Every datasheet hides a payload-CG derating curve: full payload only exists hugging the flange. The linear approximation here mirrors the typical curve's shape — when utilization passes ~85%, open the manufacturer's wrist-moment diagram before committing the cell.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Gripper Sizing — Payload + CG Envelope Check
Gripper Sizing — Payload + CG Envelope Check computes the governing relationship m_allowed ≈ m_rated × (CG_rated / CG_actual), capped at rated live as you type. Every datasheet hides a payload-CG derating curve: full payload only exists hugging the flange. The linear approximation here mirrors the typical curve's shape — when utilization passes ~85%, open the manufacturer's wrist-moment diagram before committing the cell. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Gripper Sizing — Payload + CG Envelope Check
- 1Enter your values — Gripper/tool mass, Part mass, Combined CG offset, Robot rated payload and more (sensible defaults are pre-filled).
- 2Read the live results: Total payload, Allowed at your CG, Utilization.
- 3Check the "with your numbers" line to see m_allowed ≈ m_rated × (CG_rated / CG_actual), capped at rated substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Payload + CG Envelope Check?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula m_allowed ≈ m_rated × (CG_rated / CG_actual), capped at rated with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Every datasheet hides a payload-CG derating curve: full payload only exists hugging the flange.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the gripper sizing — payload + cg envelope check use?+
It evaluates m_allowed ≈ m_rated × (CG_rated / CG_actual), capped at rated, exactly as published. Sources: Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Every datasheet hides a payload-CG derating curve: full payload only exists hugging the flange. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
Holding-force and sizing math for a payload + cg envelope check including acceleration and safety factor. A free industrial robot kinematics & cell design tool. The linear approximation here mirrors the typical curve's shape — when utilization passes ~85%, open the manufacturer's wrist-moment diagram before committing the cell. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
