Lesson 1Pedestrian exposure: loads travelling over people and walkway interactionsThis section examines how pedestrians are exposed to crane hazards, including loads over people, walkway conflicts, and blind spots in local sites, and describes layout, barriers, and procedural controls to separate people and loads.
Mapping pedestrian routes and crane travel pathsRules for never travelling loads over personnelUse of barriers, exclusion zones, and signageSpotters and taglines near walkways and doorsManaging visitors and non-routine foot trafficLesson 2Environmental and workplace hazards: obstructions, poor lighting, slippery floorsThis section reviews environmental and workplace hazards that affect crane safety in Zimbabwean workshops, including obstructions, poor lighting, slippery floors, and noise, and explains how to inspect, report, and correct these conditions.
Identifying overhead and side obstructions to travelAssessing lighting levels at controls and load pathManaging floor conditions, spills, and housekeepingEffects of temperature, wind, and humidity indoorsNoise, visibility, and line-of-sight limitationsLesson 3Concurrent operations and multi-crane interactions when sharing a bayThis section covers hazards when multiple cranes or tasks share a bay in local facilities, including collision, load interference, and signal confusion, and explains planning, zoning, and communication controls to keep concurrent operations safe.
Planning lifts when multiple cranes share a bayCrane zoning, interlocks, and anti-collision systemsCoordinating signals between multiple operatorsManaging simultaneous lifting and adjacent workSpotter roles during congested crane operationsLesson 4Load-related hazards: swing, snagging, unbalanced loads, tipping during liftThis section covers load-related hazards such as swing, snagging, unbalanced loads, and tipping in Zimbabwean lifts, explaining how to predict load behaviour, plan rigging geometry, and control movement during all phases of the lift.
Causes and control of load swing and driftPreventing snagging on structures and equipmentCentre of gravity and unbalanced load indicatorsTipping risks for suspended and supported loadsUse of taglines and controlled accelerationLesson 5Maintenance and working at height hazards: access to runway, fall-from-height during maintenanceThis section addresses hazards during crane maintenance and work at height in local settings, including runway access, falls, dropped tools, and isolation failures, and details safe access, fall protection, and permit-to-work expectations.
Safe access to runways, walkways, and platformsFall protection selection and correct use on cranesLockout, tagout, and test-before-touch stepsPreventing dropped tools and loose materials aloftPermit-to-work controls for crane maintenanceLesson 6Human factors and communication failures: miscommunication, complacency, operator distractionThis section explores human factors such as fatigue, distraction, complacency, and poor communication in Zimbabwean teams, showing how they contribute to crane incidents and how to improve teamwork, signalling, and safety culture.
Recognising fatigue, stress, and distraction in operatorsStandardising hand signals and radio phraseologyManaging complacency during routine repetitive liftsBriefings, pre-lift huddles, and post-job reviewsDesigning controls to reduce human error likelihoodLesson 7Emergency and rescue hazards: dropped load scenarios, entrapment, electrical incidentsThis section addresses emergency and rescue hazards in local operations, including dropped loads, entrapment, and electrical incidents, and explains planning, drills, and equipment needed for safe response without creating new risks.
Planning for dropped load and near-miss eventsResponding to entrapment and crush situationsElectrical contact, arcing, and shock hazardsEmergency stop use and post-incident isolationRescue roles, equipment, and coordinationLesson 8Rigging and sling failures: wear, incorrect selection, improper inspectionThis section focuses on rigging and sling hazards in Zimbabwean use, including wear, damage, wrong capacity selection, and missed inspections, and explains how to recognise defects and match rigging to the planned lift.
Recognising wear, cuts, and broken wires on slingsSelecting slings and hardware for load and hitch typeTagging, identification, and capacity markingsInspection frequencies and removal-from-service rulesStorage, handling, and avoiding rigging misuseLesson 9Procedural and administrative gaps: outdated procedures, lack of pre-use checksThis section examines how outdated procedures, missing pre-use checks, and weak administration create hidden hazards in local sites, and explains how to build, update, and enforce practical crane procedures and checklists on site.
Identifying outdated or conflicting crane proceduresDesigning effective pre-use and shift inspection checklistsLinking crane procedures to risk assessmentsDocument control and version management for proceduresTraining and sign-off on new or revised proceduresLesson 10Crane system failures: hoist, trolley, bridge mechanical and electrical faultsThis section analyses crane system failure modes in hoists, trolleys, bridges, and electrics in Zimbabwean cranes, and shows how inspections, testing, and fault reporting prevent sudden breakdowns and unsafe operating conditions.
