               Boom Trucks
• Boom trucks are used
  in a variety of ways
  throughout the
  construction industry.
• They provide easy
  transportation and
  installation of
  materials, speeding
  up deliveries and
  reducing project
  schedules.               Source: Manitex.com

                      • The versatility and
                        maneuverability of
                        boom trucks make
                        them the ideal solution
                        to many construction
                        problems.

        History of Boom Trucks
• Boom trucks have been
  around for over 50 years
  and have evolved from the
  basic towing truck with
  limited capacity to large
  pieces of equipment that
  can easily lift more than 40   Source: RoadsideAmerica.com



  tons.
• Their electrical systems
  have also improved, now
  providing the controller
  with accurate loading
  capacities and limitations.      Source: Manitex.com
     History of Boom Trucks
• While the first boom trucks were operated
  from either within the truck or along its side,
  today‟s trucks can be operated from afar with
  the use of remote controls.
• These remotes not only
  improve the usefulness
  of boom trucks, but also
  increase safety for the
  crews who use them.                 Source: RadioRemote.com
       Types of Boom Trucks
• Boom tucks come in various shapes and
  sizes. Common variations include: Knuckle,
  Jib, Gin, and Conveyer. However, the most
  common, especially for road construction, is
  the standard form shown below.

  project applications.
             Safety Concerns
• Proximity of boom to power lines.
• Likelihood of electrical storms in working area.
• Stability of ground surrounding the boom truck
  location.
• Overloading boom trucks beyond recommended
  capacities.
• Inadvertently manipulating boom truck controls
  through either material or worker accidental
  contact.
• Monitoring movement of the boom and truck itself.

           Analysis of Data
• Most boom truck accidents are the result of
  some part of the truck contacting power
  lines.
• Power line contact is by far the most
  dangerous type of accident that can occur
  during operation.
• On average, 1.45 employees are injured
  when a portion of the truck contacts a
  power line.

        Boom Truck Accident:
           An Example
• A crew was installing pipe in a 4 foot deep, 1
  1/2 foot wide trench.
• After manipulation, the boom finally came to
  rest 2 feet away from the power line.
• While a 32 year old plumber was holding the
  pipe in their left hand, “the crane operator
  and laborer at the opposite end of the pipe
  heard an „arcing‟ noise.”
• As a result, the plumber was shocked and
  died at a local hospital 30 minutes later.

             Boom Truck Safety
• Employees should always wear the necessary
  Personal Protective Equipment when using boom
  trucks.
• At a minimum, employees should wear a hardhat,
  fitted clothing that would prevent snagging on controls,
  and safety-toed boots.
• Additionally, the OSHA Manual
  should be consulted to ensure
  employees are wearing the
  appropriate PPE for the material
  being transported and lifted.            Source: Terex-Waverly.com

                                                    operated at safe distances
                                                    from nearby power lines.

• When using the
  boom truck to
  unload material,
  ensure that it is
  properly level in
  order to prevent
  truck tipping and
  mechanical failure.

• Overloading a boom
  truck can cause
  catastrophic failure of
  the hydraulic system
  and the boom itself.
• Be sure to follow the
  manufacturer loading
  limitations for each
  boom truck.               Source: LiftEquipmentSafety.blogspot.com

                            • Ensure that the
                              material is properly
                              secured when
                              unloading or loading
                              the truck.
                            • Material can weigh
                              several tons and
                              cause death if not
                              handled properly.

        Boom Truck Safety
• When driving the truck, always ensure
  that the clutch is disengaged to
  guarantee the boom is disabled during
  commute.
• Use ground guides or flaggers while
  operating the truck in reverse to protect
  from driving related accidents.
• Use a spotter whenever operating the
  boom to monitor its location at all times.
Boom Truck Maintenance
                              • Boom trucks need to
                                be regularly
                                maintained in order to
                                ensure proper
                                function.
                              • Consult the
                                manufacturer‟s
                                specifications sheet to
                                keep the truck working

                                avoid potential
                                mechanical failure.
     Boom Truck Maintenance
• Check the electronic
  equipment used to
  maneuver and monitor
  the boom truck
  regularly.
• Failure of these items
  can lead to set up
  mistakes and material
  overloading which can
  result in severe injury
  or even death.            Source: Terex-Waverly.com
