When a crane lifts personnel, the regulatory stakes change immediately.
Unlike material lifting, hoisting workers in a crane personnel platform (man basket) is tightly regulated under OSHA 1926.1431 and informed by ASME B30.23. These standards exist because personnel lifting exposes workers to elevated fall risk, dynamic forces, and catastrophic failure potential if equipment is improperly designed or used.
If you are specifying, approving, or operating a crane suspended man basket, understanding these requirements is not optional — it is central to compliance, liability management, and worker safety.
This guide breaks down what OSHA and ASME require, how the standards interact, and what a compliant crane personnel platform must include.
Why OSHA 1926.1431 Exists
OSHA 1926.1431 governs personnel hoisting by cranes in construction environments. It recognizes that cranes are primarily designed for material lifting, not people — and therefore imposes strict conditions before workers can be lifted.
OSHA permits personnel lifting only when:
- It is infeasible to provide safer access (such as scaffolding or aerial lifts).
- A thorough lift plan is prepared.
- The personnel platform meets specific design requirements.
- The crane and rigging are inspected and tested.
In short: personnel lifting is allowed, but highly controlled.
Key Design Requirements Under OSHA 1926.1431
To comply with OSHA man basket requirements, a crane personnel platform must include:
Guardrails and Fall Protection
- Top rail approximately 42 inches high
- Midrail halfway between floor and top rail
- Toeboards at least 4 inches high
- Anchorage points for personal fall protection systems
These features reduce fall risk while the platform is suspended.
Structural Integrity
The platform must be designed by a qualified person and capable of supporting:
- Its own weight
- The weight of intended occupants
- Tools and materials
- Dynamic loads during hoisting
The design must prevent tipping, excessive deflection, or instability.
Suspension System
The platform must:
- Be attached to the crane using a reliable suspension system
- Use a bridle or multi-leg sling arrangement
- Ensure stable lifting geometry
Single-point improvised lifting is not acceptable.
Proof Load Testing
Before lifting personnel, OSHA requires a proof test at:
125% of the platform’s rated capacity
This test verifies structural integrity under controlled conditions. Many engineered platforms incorporate integrated test weight systems to simplify this process.
What ASME B30.23 Adds
While OSHA provides enforceable regulations, ASME B30.23 provides detailed engineering guidance for personnel lifting systems.
ASME focuses on:
- Design factors
- Load calculations
- Structural safety margins
- Rigging practices
- Inspection criteria
It reinforces that personnel platforms must be engineered lifting devices — not adapted material baskets.
Structural Safety Factors for Personnel Platforms
Unlike material-only lifting platforms, personnel platforms typically require higher safety factors because human life is directly at risk.
Engineering must consider:
- Static loads
- Dynamic crane motion
- Sling angle effects
- Wind loading
- Off-center occupancy
Lifting lugs, welds, and structural members must meet the design criteria defined by applicable standards and qualified engineering review.
Inspection Requirements Under OSHA
OSHA requires multiple layers of inspection:
Pre-Lift Trial Lift
Before lifting personnel:
- Conduct a trial lift to ensure balance and stability
- Verify crane capacity at the intended radius
- Confirm no interference with structures
Daily and Pre-Use Inspections
Inspect:
- Rigging components
- Lifting lugs and welds
- Guardrails and anchor points
- Structural integrity
Ongoing Maintenance Inspections
Platforms must be removed from service if:
- Cracks appear in welds
- Lifting points deform
- Structural damage occurs
- Corrosion compromises integrity
Inspection documentation should be maintained.
Common OSHA Violations Involving Man Baskets
Compliance failures often involve:
- Using material-only platforms for personnel
- Skipping proof-load testing
- Improper sling angles
- Missing fall protection anchor points
- Lack of documentation
Many citations occur not because the platform looks unsafe — but because documentation or testing procedures were not followed.
Material Basket vs Personnel Platform: Critical Distinction
A material lifting basket is not automatically a compliant personnel platform.
Personnel platforms require:
- Fall protection anchorage
- Guardrails and toeboards
- Proof-load procedures
- Personnel-specific inspection protocols
- Clear compliance documentation
Using a material-only crane basket for personnel lifting without meeting OSHA 1926.1431 is a violation.
Documentation Required for Compliance
A compliant crane suspended man basket should include:
- Engineering certification
- Rated capacity documentation
- Proof-load test record
- Inspection checklist
- Operating instructions
- OSHA Certificate of Compliance (where applicable)
Without documentation, even a well-built platform can fail compliance review.
When Is Personnel Hoisting Allowed?
OSHA requires that personnel lifting be used only when:
- Scaffolding or aerial lifts are not feasible
- The lift is properly planned
- Crane capacity is sufficient
- A competent person supervises operations
Personnel lifting is not a convenience — it is a controlled exception.
Engineering Checklist for OSHA-Compliant Crane Personnel Platforms
Before approving or purchasing a crane man basket, confirm:
- Designed by a qualified engineer
- Guardrails and toeboards meet OSHA dimensions
- Rated capacity clearly labeled
- Multi-leg suspension system included
- 125% proof-load testing capability
- Documented inspection procedures
- Fall protection anchorage points installed
- Compliance documentation available
Frequently Asked Questions
What does OSHA 1926.1431 require for crane personnel platforms?
It requires engineered platforms, fall protection, proof-load testing at 125% capacity, trial lifts, inspections, and proper supervision before lifting personnel.
Is ASME B30.23 mandatory?
ASME standards are not laws themselves but are widely adopted and referenced by OSHA and industry best practices for personnel lifting systems.
Can a material basket be used to lift people?
Only if it meets all OSHA 1926.1431 requirements for personnel platforms. Most material baskets do not.
How often must crane personnel platforms be inspected?
Pre-use inspections are required before each lift, with additional periodic inspections depending on use and site policy.
Need a Fully Compliant Crane Personnel Platform?
If your operation requires personnel lifting, the safest path is an engineered crane suspended man basket designed specifically to meet OSHA 1926.1431 and ASME B30.23 requirements.
