Boom Truck – Inspection Procedure

Follow this structured procedure to ensure safe and compliant boom truck operations

Boom Truck Inspection Procedures

Follow these detailed procedures to ensure a thorough and systematic inspection that meets industry regulations and manufacturer specifications for safe boom truck operation.

Boom Inspection Procedure

  • Park on level ground with engine off
  • Visually inspect boom sections for dents, cracks or deformation
  • Check boom pivot pins and retaining hardware
  • Inspect extension cylinders and wear pads
  • Verify boom angle indicator accuracy
  • Check all boom markings and load charts for legibility
  • Inspect boom stops and anti-two-block devices
  • Document any defects requiring repair

Outrigger Deployment Check

  • Ensure work area is clear of personnel and obstacles
  • Deploy outriggers to full extension and set properly
  • Verify truck is level using bubble level indicators
  • Check stability by testing minimal boom movements
  • Inspect ground conditions under outrigger pads
  • Verify all outrigger locking pins are engaged
  • Check hydraulic system for leaks during deployment
  • Test outrigger controls for proper function

Wire Rope Inspection

  • Extend boom partially for better visibility
  • Inspect entire length of wire rope for broken wires
  • Check for flattening, kinks, or bird-caging
  • Verify end connections and attachments
  • Ensure proper lubrication of cable
  • Inspect sheaves for cracks or abnormal wear
  • Check anti-two-block mechanism functionality
  • Test load line spooling during operation

Hydraulic System Check

  • Inspect all hydraulic hoses for leaks or damage
  • Check hydraulic fluid level in reservoir
  • Observe cylinder operation for smooth movement
  • Listen for unusual noises from hydraulic pump
  • Verify hydraulic pressure gauges read within specs
  • Inspect fittings and connections for leaks
  • Check hydraulic filters for contamination indicators
  • Test hydraulic controls for responsiveness

Operational Testing Procedures

After completing visual inspections, these operational tests must be performed to verify all systems function correctly before commencing work.

Load Moment Indicator Test

  • Review load chart for planned operations
  • Check LMI calibration and operation
  • Verify warning systems function at appropriate limits
  • Test override systems if equipped
  • Confirm angle and radius readings are accurate
  • Simulate load conditions if possible
  • Test alarm systems at 90% and 100% capacity
  • Document LMI test results in inspection report

Control Function Testing

  • Test each control function individually
  • Verify smooth operation of boom raise/lower
  • Check extension/retraction without binding
  • Test rotation function in both directions
  • Operate winch up/down at various speeds
  • Check emergency stop button functionality
  • Test horn and warning devices
  • Verify operator comfort and control access

Stability Testing

  • Ensure outriggers are properly deployed
  • Gradually rotate boom through full range of motion
  • Test stability at different boom angles
  • Monitor level indicators during operation
  • Check for unusual movement or settling
  • Test stability with rated load (if applicable)
  • Verify truck chassis remains stable
  • Document any stability concerns immediately

Safety Systems Verification

  • Test anti-two-block systems
  • Verify boom angle indicator accuracy
  • Check function of all limit switches
  • Test overload protection systems
  • Verify all warning lights and alarms
  • Check emergency lowering systems
  • Test operator presence controls
  • Verify all safety placards and decals are legible

Regulatory Compliance Procedures

These procedures ensure compliance with OSHA regulations, ANSI standards, and manufacturer requirements for safe boom truck operation.

Documentation Requirements

  • Verify operator qualification and certification
  • Check annual inspection documentation
  • Review load rating charts for accuracy
  • Ensure operator manual is accessible
  • Verify maintenance logs are up-to-date
  • Check for any outstanding safety bulletins
  • Review previous inspection reports
  • Document current inspection completely

OSHA Compliance Check

  • Verify annual inspection within past 12 months
  • Check for proper crane hand signals posting
  • Ensure ground conditions assessment completed
  • Verify power line safety procedures in place
  • Check operator certification documentation
  • Verify taglines available when needed
  • Ensure proper PPE is available and used
  • Check for required safety placards and decals

Pre-Lift Planning

  • Verify load weight is known and documented
  • Check load chart for selected configuration
  • Assess site conditions and hazards
  • Verify outrigger deployment area is suitable
  • Establish communication protocols
  • Review lift plan with all personnel
  • Ensure tagline requirements are met
  • Document lift plan and pre-lift meeting

Post-Operation Shutdown

  • Return boom to stowed position
  • Retract and secure outriggers properly
  • Secure all loose items and attachments
  • Document any issues observed during operation
  • Check for fluid leaks after shutdown
  • Secure cab and controls against unauthorized use
  • Update maintenance log with hours operated
  • Complete post-operation inspection report
