Articulating BoomAerial Lift Types

A self-propelled,integral frame, boom

supported platformwhich telescopes &rotates beyond the

base dimensions toposition personnelalong with their tools

and necessarymaterials atoverhead work

locations.


15/66


Fork-truck workplatform

We have a fork-truck workplatform at the Univ.Services Building (USB).

Since the platform has astandard railing system,tying-off is not required aslong as your body stayswithin the confines of therailings. Except for verticalpositioning, the truck must

not be relocated while aperson is in the platform.

Specific Hazards


17/66


Specific Hazards

There are specifichazards associatedwith operatingaerial platforms.

These hazards are: Fall Hazards

Tip-Over Hazards

Collision Hazards Electrocution

Hazards


18/66


Aerial Lifts

(Articulating &Telescoping Boom

Lifts)

Fall protection isrequired due topotential for beingbounced out of liftand to keep

worker fromclimbing out of thebasket.

Specific Hazards --Fall Hazards


19/66


Any occupant of aself-propelled boom

must wear fallprotection (bodyharness and shock-absorbing lanyard.)

Do not sit, stand orclimb on the

platform guardrails Do not climb out of

the platform when

it is raised.

Specific Hazards Fall Hazards


20/66


Specific Hazards Tip Over Hazards

Do not exceed the

rated platformcapacity

Platform is intended

to be elevated on afirm, level surfaceunless equipped with

outriggers

Do not operate in

strong or gusty windsAftermath of Miller Park Big Blue cranecollapse.

Do not drive neardrop-offs, holes, orloading docks.

Do not raiseplatform onuneven or softsurfaces.

Do not drive ontouneven or softsurfaces when

elevated. Do not raise

platform on slopeor drive onto slopewhen elevated.

26/66


Specific Hazards -- Collision

These include hazards to theaerial platform & surroundingareas as well as personnelcollisions that result in injury.

Check work area forobstructions or other hazards

Do not lower the platformunless the area below is clearof personnel & obstructions

Limit travel speed accordingto condition of groundsurface, congestion, slope,location of personnel

Be aware of blind spots


27/66


Specific Hazards -- Electrocution

Operations manualand decal on liftshould provideinformation on safedistance to maintain

when working nearelectrical apparatus

Assume all

electrical partsand w ires areenergized unless

known otherw ise.

Minimum Safe Approach

Distance


28/66


Maintain safe clearancesfrom electrical power

lines and apparatus You must allow for

platform sway, rock, or

sag This work platform does

not provide protectionfrom contact with or

proximity to anelectrically chargedconductor

Specific Hazards -- Electrocution


29/66

Special Hazards: Battery Charging

Charge batteries only inwell-ventilated areas

Lead-acid batteriescontain sulfuric acidwhich will damage eyesor skin on contact

Wear eye/faceprotection, protectivegloves and clothing forbattery maintenance

Precautions and Prohibitions


32/66


Precautions

Check the following:

Outriggers, stabilizersand extending axles

Upper and lower controlstations including

auxiliary/emergencycontrols.

Platform handrails andgates.

Level gauge (as shown inphoto)


33/66


Precautions

Operators must:

Keep work surfaces and elevating mechanisms

clean and clear of debris. Before attempting to clean a machine, lower

the platform to the stowed position and turnoff the engine.

Clean steps, railings, ladders, and platformfloor. Remove grease or oil. Replace anti-skid tape or paint, as required. Remember-slippery surfaces can be hazardous.

Remove or put away tools, ropes and hooks.

Remember-loose items on the floor couldcause an accident.


34/66


Precautions

CHECK AT GROUND OR FLOORLEVEL:Inspect the surface on which you will

be working. Look for holes, obstacles,drop-offs, rough spots, and weak spotson covers on ramps or floors. Look foroil spills, wet spots, slippery surfaces,

soft soil or standing water. Watch foranything that may make you losecontrol or cause the platform to tipover. Clear away all debris, and make

sure all passages are clear.

UWM Hefter Center (Nov. 2008):Equipment on soft soil, with cribbing

under wheels.


35/66


Precautions

Operators must:

Think about how you will

approach the area, andwhere you will place yourmachine for proper liftclearance.

Lock out the controls of anyoverhead bridge or cranethat the boom may crossthe path of.

Check clearances of

doorways, canopies, andpower lines, also checkclearances whentransporting the platform on

a truck or trailer.


36/66

Make the Right Start

Know rated workload ofyour machine and neverexceed it

Know weight of allpersonnel, tools and

other items placed on theplatform

Disperse load evenlybefore raising the

platform

Do not carry materials on

railings unless approvedfor that purpose

Aerial platform must beon a firm, flat, smooth

and level surface whenplatform is raised



37/66

Proper Mounting

Use 3-point contact

Always face the machine

Use handrails, ladders or

steps

Never grasp control leverswhen mounting orclimbing off

Never walk or climb theelevating assembly to gainaccess to an elevated

platform

Check that all handrails,toeboards, gates andentry chains are in placeand secured beforeraising the platform

Enter and exit theplatform from the groundonly



38/66

Test the Controls

After starting, recheck allgauges and lights

Check audible and visiblealarms

Check control functions,

including emergency stopmechanism

Recheck steering, rightand left

Move slowly until you are

certain everything isoperating properly

Be certain you have fulltravel & automatic brakecontrol

Be sure you can lowerelevated platform



39/66

Safe Operating Practices

Only designatedoperator shouldoperate controls

Never jam an

operating controlfrom one traveldirection to another.

Return to neutral,stop, then proceed inthe other direction

Avoid sudden stops,starts or changes indirection

Never attempt to

work controls exceptfrom operatorscontrol station or

lower control station



40/66

Watch Out for Others

Never allow anunqualified orunauthorized personto operate lift

Keep everyone clearof a workingplatform

Never permit anyoneto stand or passunder a raised

platform

Never drive an aerialplatform up tosomeone standing infront of a fixed

object Never move or

position any park of

a machine overanother person



41/66

Work Safely

When platform hasbeen raised toworking position, becautious to prevent

any object fromstriking or interferingwith operating

controls. Secure all tools,

equipment or other

materials

Keep ropes,electrical cords andhoses coiled andstowed away when

not in use Keep platform floor

clear of debris and

loose objects whichmight cause you toslip



42/66

Never use ladders,planks, steps or other

devices to provideadditional reach orgain greater height

Do not lean over orsit or climb on theplatform railing

Always keep both feeton platform floor atall times

Never belt off toadjacent structure

when working onplatform

Never allow anyone to

tamper with, serviceor operate a machinefrom lower control

station whilepersonnel are in theplatform except in an

emergency

Work Safely

Pallet Jacks

Before picking up loadmake sure forks arelowered, squared &wide enough to providegood support

Move under load as faras possible & makesure load is centered &stable before lifting

Raise load steadily andslowly

When forks are

raised, machine isless stable


45/66


Position yourself so youhave the best visibility either forward or

backward All body parts must be

within the boundaries ofthe vehicle

Face the direction inwhich you are traveling

Always keep at least onehand on the controls

Watch your speed

Allow for wide-swingsaround corners

Walkie-Rider Pallet Jacks


46/66


Prohibitions

Do not overload

Do not use without railings & entry gate in place

Do not use if work platform is not working orparts are damaged

Do not use near moving vehicles

Do not stand or sit on guardrails

Do not use under the influence of alcohol ordrugs

Do not override safety devices

Do not leave unattended with key in switch Do not use ladder or other device to increase

size or working height

Do not use with damaged wheels or tires orimproperly inflated tires


47/66


Fall Protection

Personal fall protection (i.e., tying off) normallyisnt necessary on vertical lifts unless the workextends beyond the railing.
