Aerial Lifts

Types of Aerial Lifts and locations– Auto Shop: TMZ-34/19 – McPhee Room 104: AWP-24– McPhee Rooms 164/263A: UL-31/37

Aerial Lifts

Safety Information:– Work platform is to be used by trained and

authorized operators only.– Maximum platform capacity:

• TMZ-34/19 is 500 pounds & possible 2 persons.• AWP-24 is 300 pounds & no more than one person• UL31/37 is 300 pounds & no more than one person

Aerial Lifts

Aerial Lifts Pre-Operation Inspection

– Be sure that the manuals are legible and in the storage container located on the platform

– Be sure that all decals are legible and in place– Check the hydraulic power unit oil level– Platform and Ground Control Panel must be

tested prior to use to determine that such controls Panel are in safe working condition.

Aerial Lifts Work Place Inspection

– Do a visual inspection of the work area prior to beginning work

• Hazardous locations– Drop-offs or holes– Bumps, floor obstruction or debris– Inadequate surface support to withstand all load forces

imposed by the machine• Clearance• Overhead obstructions

– High voltage conductors• The presence of unauthorized personnel• Other possible unsafe conditions

Aerial Lifts Set up

– Position machine below desired work area– Insert key and turn to the ground control position– Pull out the red Emergency Stop buttons at the

ground and platform controls– For TMZ – 34/19:

• Pull the four (4) outriggers release handle and lower the outriggers, and be sure the outrigger lock pins are locked

– For AWP – 24 and UL - 31/37: • Remove the four (4) outriggers from their storage

sockets and slide into base sockets until lock pins snap into outrigger holes.

Aerial Lifts Set Up Cont.

– For TMZ – 34/19, AWP – 24, and UL – 31/37:• Adjust the four (4) outrigger leveling jacks by turning

jack handle clockwise until each pad is in firm contact with floor.

• Check the interlock display lights at the ground controls (TMZ-34/19 and AWP -24 only):

– Confirm that the corresponding light is on– If the interlock display light is flashing, continue adjusting

the outrigger until the light is on• While watching the base bubble level, continue to

adjust each leveling jacks until base is level (bubble in the center circle)

• Repeat procedure for each of the remaining outriggers

Safe Work Practices– Ground controls shall not be operated during

use, unless instructed to do so by person in the platform or in an emergency.

– Never elevate platform unless all four (4) outriggers are properly installed, leveling jacks contact floor and base is level.

– Never adjust leveling jacks while platform is occupied.

Aerial Lifts

Safe Work Practices Cont.– Employees shall always stand firmly on the floor

of the basket.• Do not stand, sit or climb on edge of the basket or

guard rails.• Do not use planks, ladders, or other devices for a

work position.

– Keep the platform floor clear of debris.– Do not override safety devices.– Learn and practice the principles of safe machine

operation contained in the operator’s manual.

Aerial Lifts Two Major Safety Hazards:

– Electrocution Hazards - Caused by operating close to power lines.

• It is easy to accidentally contact energized power lines.

• This machine is not electrically insulated and will not provide protection from contact with electrical current.

• If lift comes in contact with energized lines, personnel on the ground or in the platform must not touch or operate the machine until energized power lines are shut off.

• Do not operate the machine during lighting or storms.

Aerial Lifts

Two Major Safety Hazards Cont.– Fall Hazards - Caused by improper operation

and/or improper set up.• Fall hazard due to the potential for being bounced out

of lift or from climbing out of the basket.• Over reaching• Swinging under over hanging limbs, structures or

lines.• Stumbling over tools inside the basket.

Aerial Lifts

Personal Protective Equipment– Hard hats and Safety glasses are required

whenever working from an aerial lift.– A full body harness and lanyard shall be worn– Lanyard needs to be attached to anchor provided

in platform when working from an aerial lift.– All Aerial Lift operators must visual inspect the

body harness & lanyard before each use.

Aerial LiftsHazards / Precautions

– Tip-Over Hazards• Do not drive or position lifts near the edge of loading

docks drop-offs or holes.• Do not raise platform on uneven or soft surfaces• Do not drive onto uneven or soft surfaces when

elevated • Do not raise platform in windy or gusty conditions• Do not use the platform as a crane (the TMZ-34/19 has

a cargo hook that can be used in place of the platform to lift 500 pound loads).

• Do not place or attach overhanging loads to any part of the platform.

Hazards / Precautions Cont.– Tip over Hazards Cont.

• Do not place ladders or scaffolds in platform or against any part of this machine.

• Be sure all tires are in good condition and lug nuts are properly tightened.

• Do not fully lower the booms unless the booms are aligned with the tongue. The booms must be lowered onto the boom rests.

Hazards / Precaution Cont.– Lifting Hazards

• Use proper lifting techniques to move, load or unload the machine.

• Use proper lifting techniques when installing or removing the platform.

• Burn Hazards– Batteries contain acid. Always wear protective clothing and

eyewear when working with batteries.• Explosion Hazards

– Do not contact the battery terminals or the cable clamps with tools that may cause sparks.

• Electrocution Hazards– Inspect daily for damage cord, cables and wires. Replace

damaged items before operating• Lifting Hazard

– Use the appropriate number of people and proper lifting techniques when lifting batteries.
