PRE-CONTAINERISATIONMODERN TWEENDECKER
STOWAGEPlacing cargo in a ship in preparation for a voyageProvides for safety of shipProtect cargoOptimise storage spaceAllows easy access to cargo at port of unloading (discharge)
Term useMay be used for any form of cargo
Drybulk, liquid, breakbulk, container, ro-roMay be used for any form of transport mode
Sea, air, road, rail

PRE-CONTAINERISATIONPORT TO PORT SHIPMENTS
TreadwheelsHuman power to lift cargoFrom about 1500sCapacity 2 to 3 tons
1745 (top picture)Oestricher Kran, Oestrich, GermanyWine-loading craneBuilt 1745Working until 1926Treadwheel worked by 4 men
1900s (lower picture)Hand worked crane
PRE-CONTAINERISATIONHARBOUR CRANES – MANUAL POWER
PRE-CONTAINERISATIONLOADING TEA – 1870s
Fairbairn Steam Crane Built in 1878
Cost £3,600 for the machineryWeighed 120 tons2 steam powered engines
Turning Lifting
Enclosed cab for operatorCapacity
Could lift up to 35 tons (35.56 tonnes)Outreach 11mHeight 12m
UseDesigned for ship engine repairBy 1890 outdated
Ships large for craneRemained in use until late 1940sStill working today
PRE-CONTAINERISATIONSTEAM POWERED HARBOUR CRANES
Electric rail mounted cranesFirst built in 1892Southampton Dock AuthorityReduced cost (central power source)No start up delaysLighter construction
Raised in air - work under legsMounted on wheelsMoved along quay wallMoved along ship whilst working
CapacityCargo terminals - 3 tonsShip yards – up to 30 tons
PRE-CONTAINERISATIONELECTRIC HARBOUR CRANES
Lifting cargoVertical movement of cargo
Level luffing (luffing cranes)Horizontal movement of cargoLevel = at same vertical height
SlewingRotational movement of cargo
PRE-CONTAINERISATIONCRANE TERMINOLOGY
LuffingSlewing (rotating)
Also known as luffing cranesWhen moving cargo horizontally the cargo is kept at the same heightCommon type of port crane
PRE-CONTAINERISATIONLEVEL LUFFING HARBOUR CRANES
Single mast or poleControlled by lines (usually 4)
Each line has different origin locationDoes not use counterweightsProvides stability to crane
Hinged freely at the bottomPole can move in all 4 directionsCables and pulleysVery free movement
PRE-CONTAINERISATIONGEARED SHIPS - DERRICK CRANES
Projecting arm which is pivoted to allow it to be raised or loweredBarkald
4 pedestal jib cranesCapacity
30 tonnes20 cubic metres
PRE-CONTAINERISATIONGEARED SHIPS - JIB CRANE
PRE-CONTAINERISATIONSHIP – QUAY – SHED - ROAD
British ports in 1961Total of 150,000 people employed in docks
53,500 were registered dockers employed per day16,500 were registered dockers employed per week
Port of London1967 = 20,923 dock workers1968 = 18,424 dock workers1969 = 16,560 dock workers
Registered dockers in Britain1967 there was 60,0001975 there was 32,0001989 reduced to 10,000
PRE-CONTAINERISATIONTHOUSANDS OF DOCKERS
PRE-CONTAINERISATIONDOCKER TOOLS
Britain (Rochdale Report)On average 46 deaths per year in British docks
1967 Port of London (National Association of Port Employers)Injuries per 1000 workers 129
13% of workers suffered an injuryOf all injuries 28% were spinal (back injuries)
Total of 2,700 injuriesManual handling 709 workersFalling objects 613 workersSlipping over 317 workersMechanical equipment 292 workersCaused by stepping 273 workersFalling from a height 116 workersHit by swinging load 109 workersHandling beams & hatches 40 workersCaused by hand hooks 22 workersOther 209 workers
Le Havre in early 1960s 6,000 accidents every year26 to 48 fatalities every year
