Crane Inspections: OSHA Requirements & Safety Tips for ...

Visual Inspection Steps

To ensure safety and compliance, follow these detailed visual inspection steps. Use this checklist as a guide for thorough assessment.

Frame and Support Check

Inspect the crane's structure to confirm its stability and strength. Focus on these key areas:

• Main girders and bridge components: Look for deformation, cracks, or corrosion.
• Support columns and runway beams: Check for alignment issues.
• Welds and structural joints: Inspect for signs of fatigue.
• End ties and connections: Ensure all fastenings are secure.
• Clearances: Verify a minimum of 3/4 inch between the bridge and runway.

Pay extra attention to high-stress areas and load-heavy junctions. Use a flashlight to examine dark or hard-to-see spots. Record rust spots larger than 1 square inch and deformations exceeding 1/4 inch. Once the structure is confirmed safe, move on to inspect all hardware connections.

Hardware Inspection

Evaluate the condition of fasteners and other hardware using the table below:

Component	Inspection Points	Acceptance Criteria
Bolts	Check condition	No visible gaps; threads intact
Rivets	Verify integrity	No cracks or looseness
Pins	Assess wear	Wear must be under 0.03 inches
Bearings	Test performance	No binding or strange noises

Use calibrated tools for accurate checks. Mark any questionable components with high-visibility tape for further review. Once hardware is secure, proceed to examine moving parts for wear and proper operation.

Component Check

Inspect all moving parts to catch early signs of wear or damage:

• Wire Ropes: Look for broken wires (no more than 6 per lay), kinks, or bird-caging.
• Sheaves: Check groove wear and replace if worn more than 1/8 inch.
• Hooks: Inspect for deformation and throat opening (should not exceed a 15% spread).
• Drums: Ensure proper rope spooling and assess groove condition.

Use a caliper to measure critical dimensions and compare them to the manufacturer’s specifications. Record any discrepancies.

When inspecting wire ropes, focus on high-wear areas such as:

• Sections near end attachments.
• Areas frequently in contact with sheaves.
• Portions that flex often during operation.

Take photographs of any concerning spots to ensure accurate documentation.

Operation Tests

Once visual inspections are complete, operational tests are conducted to ensure the system works as intended. These tests assess both mechanical components and control systems under various conditions.

Brake and Clutch Tests

Braking systems are tested in both loaded and unloaded scenarios to confirm:

• Hoist, bridge, trolley, and emergency brakes align with manufacturer specifications
• Brakes respond promptly and consistently
• Brake pads show normal wear, and clutches engage smoothly without slipping, even at different speeds
• Temperature changes are monitored during extended use to identify potential overheating

Safety System Check

Safety features are evaluated by:

• Testing limit switches, load limiters, anti-two block systems, and emergency stop mechanisms
• Repeating tests to ensure consistent performance
• Recording response times and stopping distances for maintenance and safety tracking

Power and Control Check

Electrical and control systems are reviewed through:

• Control Panel Inspection
  • Confirming indicator lights and displays show accurate system status
  • Testing the emergency power shutdown function
• Motion Control Verification
  • Ensuring smooth crane operation at all speed levels
  • Verifying precise and consistent positioning
• Remote Control Testing
  • Checking signal strength across the operating area
  • Identifying any delays or unexpected responses

Any irregularities, such as unusual noises, vibrations, or inconsistent behavior, should be documented. Keeping detailed records helps with proactive maintenance and ensures long-term safety and reliability.

Record Keeping

Keeping accurate records is crucial for meeting OSHA requirements and maintaining crane safety. These records help monitor maintenance activities and detect recurring issues.

Required Records

Monthly inspection records should cover the following:

• Equipment Details
  • Crane serial number and model
  • Location and department
  • Operating hours
  • Maximum rated capacity
• Inspection Information
  • Date and time of inspection
  • Inspector's name and certification number
  • Weather conditions for outdoor inspections
  • Components inspected
• Test Results
  • Load test data
  • Brake response times
  • Safety system performance
  • Control function checks

If any issues are found, include documentation on:

• Severity of the problem
• Actions needed for correction
• Dates when repairs were completed
• Results of follow-up inspections

Once these records are created, it's essential to manage them securely and systematically.

Record Management

Properly managing inspection records ensures their usefulness and compliance with regulations.

Key guidelines for record storage and management:

• Keep inspection records for at least 3 years.
• Store both digital and physical copies in secure, separate locations.
• Make records easily accessible for audits or inspections.
• Include photos of defects or completed repairs.
• Ensure all completed work has signature verification.

For an organized filing system:

• Use standardized forms with clear headers.
• Separate routine inspections from those related to incidents.
• Maintain a complete maintenance history for each piece of equipment.
• Record all modifications and upgrades.

For digital records:

• Set up daily automatic backups.
• Use version control to track updates.
• Implement quick search features for fast retrieval.

Regular audits are critical to confirm that records are accurate, complete, and securely stored, whether in digital or physical formats.

Problem Resolution

After conducting thorough testing and keeping detailed records, address any issues identified during inspections without delay.

Repair Planning

Sort inspection findings by severity to prioritize repairs and determine equipment status:
