Crane Inspector Course

Lesson 1 • Types of Crane Inspections

Distinguishes pre-shift, periodic, and annual inspection categories and their triggers. Clarifies when each type is required and what it must cover.

Lesson 2 • The Crane Inspector's Role

Defines inspector duties, authority limits, and ethical obligations. Grounds all subsequent technical content in professional accountability.

Lesson 3 • Inspection Records and Reporting

Covers required record formats, retention periods, and reporting chains. Accurate records form the legal and operational backbone of every inspection.

Lesson 4 • Inspector Qualifications and Certification

Outlines required training, experience, and certification pathways for crane inspectors. Establishes the baseline competency expected throughout this course.

Lesson 1 • Tower and Overhead Crane Types

Covers hammerhead, luffing-jib, self-erecting, and bridge crane designs. Each type presents unique structural and mechanical inspection challenges.

Lesson 2 • Drive and Power Systems Overview

Surveys diesel, electric, and hydraulic power systems that drive crane motions. Recognizing normal vs. abnormal system behavior is essential for mechanical inspection.

Lesson 3 • Mobile Crane Configurations

Examines hydraulic truck, rough-terrain, all-terrain, and crawler cranes. Understanding each configuration directs inspectors to configuration-specific failure points.

Lesson 4 • Stability Principles and Tipping

Analyzes center of gravity, tipping fulcrum, and rated capacity charts. Stability concepts underpin every load chart and outrigger inspection decision.

Lesson 1 • Boom and Jib Inspection Techniques

Covers visual and tactile methods for detecting cracks, dents, bends, and corrosion in lattice and box-section booms. Connects defect type to structural consequence.

Lesson 2 • Welds and Non-Destructive Evaluation

Introduces visual weld inspection and basic non-destructive evaluation methods applicable to crane structures. Inspectors learn when to escalate to specialist NDT.

Lesson 3 • Pins, Bolts, and Fastener Inspection

Examines wear, corrosion, and retention of structural pins, bolts, and locking devices. Fastener failures are a leading cause of structural collapse.

Lesson 4 • Mast, Tower, and Frame Inspection

Addresses inspection of mast sections, tower chords, and main frames for weld cracks and deformation. Structural integrity of these members is critical to crane stability.

Lesson 1 • Hook, Block, and Sheave Inspection

Covers inspection of hook throat opening, twist, cracks, and latch function, plus block and sheave wear. These components bear the full lifted load.

Lesson 2 • Wire Rope Discard Criteria

Applies regulatory and manufacturer discard criteria to determine when rope must be replaced. Consistent application of criteria prevents premature failure under load.

Lesson 3 • Rigging Hardware Inspection

Inspects shackles, swivels, rings, and synthetic slings for deformation, wear, and marking legibility. Rigging hardware failures account for a significant share of dropped-load incidents.

Lesson 4 • Reeving and Fleet Angle Inspection

Evaluates rope reeving configuration and fleet angles for compliance with manufacturer specifications. Incorrect reeving accelerates rope and sheave wear.

Lesson 1 • Hoist Drum and Brake Inspection

Examines drum grooves, flanges, and rope anchors, plus hoist brake lining and adjustment. Brake failure is among the most critical mechanical hazards on a crane.

Lesson 2 • Outrigger and Stabilizer Inspection

Evaluates outrigger beam extension, pad condition, and cylinder lock function. Outrigger failure is a primary cause of mobile crane overturn.

Lesson 3 • Slewing Ring and Swing Mechanism

Covers slewing ring gear tooth wear, bearing play, and bolt torque inspection. Slewing ring degradation can cause sudden superstructure separation.

Lesson 4 • Travel and Steering System Inspection

Inspects crawler tracks, rubber tires, axles, and steering components for wear and damage. Travel system condition affects crane positioning and stability during picks.

Lesson 1 • Electrical System Inspection Basics

Covers wiring condition, grounding, panel integrity, and weatherproofing of crane electrical systems. Electrical faults cause fires, shock hazards, and loss of crane control.

Lesson 2 • Load Moment Indicators and Overload Systems

Inspects and functionally tests load moment indicators, anti-two-block devices, and overload cutoffs. These devices prevent structural overload and two-blocking events.

Lesson 3 • Anemometers and Environmental Sensors

Verifies wind speed sensors, rain detectors, and visibility alarms used on tower and offshore cranes. Environmental sensors protect against weather-induced overload.

Lesson 4 • Anti-Collision and Proximity Systems

Inspects zone-limiting, anti-collision, and power-line proximity warning systems. These systems prevent crane-to-crane and crane-to-structure collisions on congested sites.

Lesson 1 • Control Lever and Pedal Inspection

Verifies control lever travel, detent function, return-to-neutral, and pedal condition. Control malfunctions cause unintended crane motions and load drops.

Lesson 2 • Instrumentation and Display Inspection

Checks load indicators, boom angle displays, fuel gauges, and warning lights for accuracy and legibility. Inaccurate instrumentation leads to misjudged lifts.

Lesson 3 • Ergonomics and Emergency Equipment

Evaluates seat condition, seatbelt function, fire extinguisher, and emergency egress. Ergonomic and emergency provisions protect operators during normal and abnormal events.

Lesson 4 • Communication Systems Inspection

Tests intercom, radio, and signal horn systems for clarity and range. Reliable communication between operator and rigger is essential for safe lifts.

Lesson 1 • Measurement Tools and Techniques

Demonstrates use of calipers, wire rope gauges, torque wrenches, and feeler gauges in field conditions. Accurate measurements support objective fitness-for-service decisions.

Lesson 2 • Deficiency Documentation and Tagging

Applies standardized deficiency codes, out-of-service tagging, and photographic documentation practices. Clear tagging prevents inadvertent use of unsafe equipment.

Lesson 3 • Pre-Inspection Planning

Covers document review, equipment history, hazard identification, and tool preparation before arriving on site. Thorough planning reduces missed defects and inspection delays.

Lesson 4 • Post-Repair Return-to-Service Inspection

Verifies that repairs address all documented deficiencies before authorizing crane return to service. Return-to-service checks close the inspection loop and confirm safe condition.

Lesson 5 • Inspection Report Writing

Structures complete inspection reports with findings, severity ratings, corrective actions, and sign-off. A well-written report protects the inspector and drives timely repairs.
