1. Legal and technical scope
Determine whether the actual activity is construction installation or general-industry maintenance. Apply the corresponding access, fall and electrical provisions. For covered overhead-crane maintenance, OSHA 1910.179(l)(2) includes lockable isolation and suitable prevention of interference by other cranes on the same runway. Construction installation uses the applicable Part 1926 provisions; the maintenance citation is not a blanket substitution for them.
Determine Federal OSHA or the applicable OSHA-approved State Plan, including public/private employer coverage. State Plans must be at least as effective and can impose different or additional requirements. The actual activity determines construction versus general-industry scope. Manufacturer instructions, consensus standards, project design and site approvals have distinct roles; this page is not a finding of nationwide compliance.

4. Hypothetical scenario and failure mechanisms
Retained source illustration: an AI-generated educational concept, not a real incident photograph or evidence of equipment suitability.The following scenario, comparisons and example records are hypothetical teaching material. They do not reproduce actual incidents, measurements, signatures or approvals.
| Item | Hypothetical situation |
|---|---|
| Initial state | A crane is stopped while its runway rail is being aligned. |
| Change | Another crane on the shared runway can still approach the work area. |
| Failure path | The isolation boundary covered only the first crane and not the shared approach or conductor system. |
| Possible harm | The approaching crane can strike workers or temporary rail, causing crushing or a fall. |
| Barrier | Suspend access, establish verified movement and electrical boundaries for all affected equipment and restore the protected work zone before resuming. |
Stopping one crane does not prevent another crane using the same runway from entering the work area. Map every affected movement and supply, coordinate operations and verify the actual barriers and isolation before elevated access.
A long rail placed on a few supports can roll, tilt or shift when clips are loosened. Review temporary stability and the order in which load transfers between lifting gear, supports and final fixings. Keep hands out of the alignment and release path.
Gauge, line and level measurements are comparable only when datum, location, instrument and installation state are recorded. Fastening can change alignment; repeat the required survey in the final tightened state rather than using temporary-placement values as final results.
Rail, pad, clip, support and joint details form a designed system. Do not mix similar-looking components or weld a gap intended to accommodate movement. Completed geometry checks do not replace end-device, clearance, protective-function and operational acceptance.
| Decision | Reason and evidence |
|---|---|
| Known facts | Another crane on the shared runway can still approach the work area. |
| Unresolved | The isolation boundary covered only the first crane and not the shared approach or conductor system. |
| Hold reason | Hold for unclear adjacent-crane or electrical boundaries, inadequate elevated access, lost signals, moved survey datums, unstable rails, defective temporary supports or clips and unexplained movement during tightening. |
| Evidence needed | Measurements and tolerances; Pad shim and support contact; Tool and fastening method; Joint and movement provisions. |
| Next decision | Suspend access, establish verified movement and electrical boundaries for all affected equipment and restore the protected work zone before resuming. |
5. Conditional decisions and common errors
| Condition | Action | Evidence | Proceed when |
|---|---|---|---|
| Adjacent travel remains | Hold access until boundaries are effective. | Crane movement and isolation map. | Intrusion prevented. |
| Rail temporarily placed | Retain accepted restraint and support. | Support and connection sequence. | Temporary stability accepted. |
| Tightening changes position | Recheck datum and survey. | Final gauge line and level. | Final geometry accepted. |
| Survey complete | Inspect remaining operational interfaces. | End devices, guards and test status. | Separate release obtained. |
| Comparison | Situation A | Situation B |
|---|---|---|
| Same recorded gauge | Datum, location and final tightened condition are identified. | Only an unlocated temporary-assembly value is recorded. |
| Work crane stopped | Adjacent travel and conductor hazards are controlled. | The shared runway remains accessible to another crane. |
6. Roles and responsibilities
| Role | Responsibility |
|---|---|
| Work supervisor | Confirm scope, task sequence, exclusion and stop authority. Coordinate review runway and operations with affected operations. |
| Technical reviewer | Resolve the actual design and equipment limits: Runway and design evidence; Affected crane IDs and travel; Rail section and gauge basis; Power and conductor boundaries. |
| Work crew | Perform inspect rails and parts using the approved procedure; report any mismatch before proceeding. |
| Inspector / assessor | Verify End-device design and checks; Clip and joint records; Conductor and structure clearance; Separate repair disposition. Record what was actually checked and what remains unresolved. |
| Release / receiving authority | Confirm Final gauge line and level; Tools and material count; Guards and access condition; Inspection test and operating status. Transfer restrictions and the next permitted stage. |
These are responsibility examples, not invented statutory credentials. Meet the actual training, competent-person, qualified-person and licensing requirements for the assigned work. Anyone may raise a hazard and request a stop; only the designated authority may release the affected stage after evidence is reviewed.
7. Hold points and record comparison
| Hold point | Evidence before release | Confirmation / approval |
|---|---|---|
| HP-0 Start | Scope, jurisdiction, equipment identity, responsible people and emergency arrangements. | |
| HP-1 Isolate and protect access | Movement and power controls; Access fall protection and rescue; Clear area below; Electrical verification and limits | |
| HP-2 Lift and temporarily place | Lift posture and support; Temporary restraints and sequence; Signals and clear zone; People outside pinch path | |
| HP-3 Inspect joints and ends | End-device design and checks; Clip and joint records; Conductor and structure clearance; Separate repair disposition | |
| HP-4 Survey and hand over | Final gauge line and level; Tools and material count; Guards and access condition; Inspection test and operating status |
Hold points are internal evidence gates. They do not replace statutory permits or actual signatures. Recheck affected gates after a change, abnormal event or shift transfer. The blank record must identify the evidence, person, time, limits and release scope.
| Record | Insufficient record | Record checklist |
|---|---|---|
| Boundary | Crane stopped | □ Movement and power controls□ Access fall protection and rescue□ Clear area below□ Electrical verification and limits |
| Parts | Rail installed | □ Material identity and condition□ Clip pad and drawing match□ Mass center and lift points□ Datum and instrument records |
| Survey | Gauge normal | □ Measurements and tolerances□ Pad shim and support contact□ Tool and fastening method□ Joint and movement provisions |
| Release | Ready to run | □ Final gauge line and level□ Tools and material count□ Guards and access condition□ Inspection test and operating status |
The □ boxes are static prompts, not saved or interactive approvals. Each checks one record element. A tick alone does not establish suitability or permission to restart. Link equipment IDs and supporting records; retain unresolved matters and the earlier record when conditions change.

Is stopping the work crane sufficient?
No. Control all affected cranes on the shared runway and the electrical conductor boundary.
Must alignment be checked after tightening?
Confirm the required final-state survey because fastening can change geometry.
Can similar clips be substituted?
Only with accepted compatibility for the actual rail, pad, support and loading design.
Does completed surveying authorize crane operation?
No. End devices, clearances, protection, required tests and operational handover remain separate gates.
Has a professional verified or approved this document?
No. This is AI-assisted reference material. Editorial and layout checks are not a physical inspection or professional technical approval. Obtain qualified professional review and required site approval before use.
