Lesson 1Ground and foundation checks: crane base, pad conditions, temporary roadways, surface bearing capacity and ground water/drainage issuesHere yuh wi learn how fi check crane foundations, pads, an access roads, verify bearing capacity against expected loads, identify soft spots, voids, or erosion, an evaluate drainage or groundwater conditions dat could undermine stability during operations.
Reviewing geotechnical and bearing dataInspecting crane base, anchors, and padsAssessing temporary roadways and access routesIdentifying soft ground, voids, and erosionEvaluating drainage and groundwater effectsRecording and reporting ground deficienciesLesson 2Communication equipment checks: radio testing, battery management, spare handhelds, signage and backup hand signal protocolsYuh wi learn how fi inspect an test communication tools, including radios, batteries, chargers, spare units, an fixed signage, an how fi establish clear backup hand signal protocols fi maintain control if primary systems fail during lifting.
Inspecting radios, headsets, and chargersTesting radio range and audio clarityManaging batteries and spare handheld unitsVerifying posted crane and site signageStandardizing hand and arm signal setsPlanning communication failure contingenciesLesson 3Weather assessment procedures: wind monitoring, gust forecasting, visibility checks, rain/icing effects and when to suspend lifting operationsDis section detail how fi monitor wind speed an direction, interpret gust forecasts, assess visibility, rain, snow, an icing, an apply manufacturer an regulatory limits fi decide when fi restrict or suspend crane operations fi weather safety.
Using anemometers and wind indicatorsReviewing weather forecasts and gust trendsAssessing visibility, fog, and night lightingEvaluating rain, snow, and icing impactsApplying wind and weather operating limitsProcedures to suspend and resume liftingLesson 4Wire ropes, hoist ropes and hooks: inspection criteria, wear limits, lubrication and end-of-life signsYuh wi learn inspection criteria fi wire ropes, hoist ropes, an hooks, including checking fi broken wires, corrosion, kinks, deformation, throat opening, latch function, lubrication quality, an recognizing end-of-life conditions requiring removal from service.
Identifying broken wires and strand damageChecking rope diameter and elongationDetecting corrosion, kinks, and birdcagingInspecting hooks for cracks and deformationVerifying hook latch presence and functionLubrication practices and discard criteriaLesson 5Tower crane structural checks: mast, slewing ring, jib, counterweights, corrosion and deformation indicatorsDis section cover visual an functional checks of tower crane structures, including mast sections, ties, slewing ring, jib, counterjib, an counterweights, looking fi cracks, loose fasteners, corrosion, deformation, an unusual noises or movement.
Inspecting mast sections and connectionsChecking ties, anchors, and bracing systemsExamining slewing ring and bolt tightnessInspecting jib, counterjib, and pendantsVerifying counterweight condition and seatingIdentifying corrosion, cracks, and distortionLesson 6Work area assessment: locating overhead power lines, adjoining buildings, public street risks, pedestrian routes and exclusion zonesHere yuh wi learn fi survey di crane work area fi overhead power lines, nearby buildings, traffic routes, an public exposure, den establish exclusion zones, barricades, an spotters fi control pedestrian an vehicle movement around lifting operations.
Locating and marking overhead power linesAssessing clearances to buildings and roofsEvaluating risks to streets and sidewalksPlanning load paths and swing envelopesSetting up barriers and exclusion zonesCoordinating with site security and trafficLesson 7Load chart interpretation: ratings by radius, configuration limits, dynamic factors and derating for attachmentsDis section explain how fi read an apply tower crane load charts, including capacities by radius an configuration, effects of jib length an counterweights, dynamic loading factors, derating fi attachments, an using charts fi plan safe lifting operations.
Understanding chart layout and terminologyCapacity changes with radius and heightEffects of jib length and configurationAccounting for wind and dynamic factorsDerating for hooks, blocks, and slingsValidating planned lifts against chartsLesson 8Crew competency and role verification: verifying riggers, signalers and operator certifications and pre-shift briefing checklistDis section cover confirming operator, rigger, an signaler qualifications, reviewing required certifications, documenting daily fit-for-duty status, an conducting structured pre-shift briefings dat align di crew pon tasks, hazards, an communication.
Verifying operator licenses and endorsementsChecking rigger and signal person qualificationsConfirming medical fitness and fatigue statusReviewing site-specific training requirementsConducting structured pre-shift briefingsDocumenting crew verification recordsLesson 9Safety devices and limit switches: function checks for overload, anti-two-block, boom angle/radius, wind speed indicators and emergency stop systemsDis section explain how fi check safety devices an limit switches, including overload protection, anti-two-block, boom angle an radius indicators, wind alarms, an emergency stop circuits, ensuring dem function correctly before any lifting begins.
Testing overload and moment limitersVerifying anti-two-block operationChecking boom angle and radius indicatorsInspecting wind speed alarms and cutoutsTesting emergency stop buttons and circuitsDocumenting safety device test results
