C7.1 Mobile equipment Flashcards
definition of mobile equipment
self propelled towed attached - mounted on mobile eqpmt to change its function pedestrian controlled remote controlled
lift truck types
counterbalance reach rough terrain telescopic materials handler side loading pedestrian controlled
counterbalance forklift rated capacity
max weight at max load centre
load centre
distance from heel of forks to centre of gravity of load
exceed = tips forward
reach lift truck
used in warehouses
work in narrow aisles
load retracted within wheel base = stable
reduced length v fork lift
rough terrain lift truck
like counterbalance fork lift diesel higher SWL enclosed cab higher chassis larger wheels
telescopic materials handler
front end forks
jib fitting = crane
telescopic boom
side loading truck
used for long loads
centre of gravity within wheel base
pedestrian controlled truck
restricted lift height operated by walking alongside use control handle battery power of hydraulic pump may be ride on
agricultural tractors
rough terrain unmade ground 2 or 4 wheel drive buckets / forks for load handling tow power take off shaft for other equipment
remotely controlled mobile eqpmt
mobile storage unit moving robot
remotely controlled narrow aisle storage & retrieval systems
mobile storage unit moving robot
proximity sensors
magnets in floor
pick up and lift storage units
remotely controlled narrow aisle storage & retrieval systems
store at height over 40 metres
no workers
interlock gates
entry systems
mobile equipment hazards
roll over overturn overbalance collision with vehicle, pedestrian, fixed object suitability for carrying passengers unauthorised start up safe operating station / platform excessive speed / fail to stop contact with wheels / tracks falling objects moving parts overheating fuel combustion gases stored energy, inc tyres
overturn causes
insecure load unstable load elevated load cornering speed uneven ground mechanical failure
forklift overturn causes
too fast sudden braking driving on slopes driving over debris under inflated tyres driving over pot holes load elevated incorrectly positioned forks overload collisions
dumper truck overturn causes
overload uneven load collision too close to edge of excavation mechanical defect incorrect tyre pressure driving across slope
operating station / platform risks
poor access to controls
limited visibility
risk of fall from eqpmt esp if reach out
proximity to other hazards
fuel combustion gases
carbon dioxide
unburnt fuel
carbon monoxide
risks with recharging battery powered equipment
acid inhale acid mist hydrogen short circuit electric shock heavy batteries
risks with LPG powered equipment
loss of LPG when connecting / disconnecting
cold cylinder
heavy cylinders
falling cylinder
risks with diesel powered equipment
dermatitis
combustible
vapour
environ risks
mobile equipment control measures
safe operation pre-op checks safe layout pederstrian protection lift plans roll over protection falling object protection speed control systems guards, barriers - prevent access to moving parts fire fighting equipment vision aids CCTV on eqpmt seatbelts
forklift safe operation
drive to conditions face direction of travel forks 10-15 cms above ground load close to heel of forks forks point up slope avoid potholes not drive across slope slow at junctions no passengers unless designed no body parts through mast park with forks lowered, park brake on not used to push / pull
