Camera Cranes
This Safety Bulletin pertains
to the safe assembly and usage of powered and manually operated, counterbalanced
camera cranes used for the purpose of television and film production.
This Safety Bulletin may also be applicable to jib arms and
similar types of units. Please consult Safety Bulletin #8 - Guidelines
for Insert Camera Cars when camera cranes are used in conjunction
with insert cars, tow dollies or process trailers.
- Each camera crane should
be accompanied by an assembly/usage manual supplied by the manufacturer/vendor.
The manual should clearly show assembly instructions, maximum payload
and maximum gross weight in all configurations, safety precautions
and maintenance procedures. Where different, manufacturer’ s/vendor’
s instructions shall supersede this Safety Bulletin. Read and follow
all manufacturer’ s placards on the equipment.
- Only persons trained
in the safe use of camera cranes should assemble and/or operate
these devices.
- When used, camera cranes
should be inspected daily by qualified personnel (e.g., key
grip, camera crane/dolly grip, vendor’ s representative or other
qualified personnel as determined by the Producer), following an
inspection protocol supplied by the manufacturer/vendor. If components
are missing, damaged or improperly fitted, the equipment should
be removed from service. Missing or damaged components are to be
replaced or repaired in accordance with the manufacturer’ s/vendor’
s procedures prior to the equipment being returned to service.
- Using the largest base
that is practical increases the stability of the unit. The appropriate
base for a crane is determined by the height, length and total load;
refer to the operating manual.
- The camera crane base
should be on a flat and level surface, platform or track system
capable of supporting the intended load. The weight of all personnel,
equipment and the camera crane should be taken into consideration.
- The payload on the
boom arm should not exceed that which can be balanced by the counterweight
system supplied with the equipment. Additional counterbalance weight
that is above and beyond that specified by the manufacturer/vendor
should not be used. The manufacturer/vendor should be consulted
regarding all extension configurations that are not explicitly specified
in the operating manual.
- Seat belts are to be
provided on all camera cranes where passengers are required for
operation. Seat belts should be maintained in good condition, and
used by all passengers.
- Pushing camera cranes
across slopes or over uneven surfaces such as cables, speed bumps,
or curbs can cause the unit to tip over.
- When operating a camera
crane, qualified personnel should ensure that there is adequate
clearance for operation. Potential obstructions or hazards, such
as power lines, helicopter rotors, fire sprinkler heads, etc. should
be considered. Qualified personnel and the designated on-set safety
coordinator should establish a safe operating zone. The designated
on-set safety coordinator should maintain the safe operating zone.
Special attention should be given to working around high voltage
power lines.

- If the camera crane
is equipped with outriggers/stabilizers, follow the manufacturer’
s instructions regarding their proper use. Care should be taken
to ensure that the feet of the outriggers/stabilizers will not sink
into soft soil or asphalt, otherwise, the unit may tip over. Adequate
means of distributing the outrigger/stabilizer load should be used,
when appropriate.
- It is recommended that
special care be used when operating camera cranes on curved track.
For example, excess speed could cause the unit to tip over.
- When moving a camera
crane on or off the track, the arm weight should be reduced to allow
for safe movement so as to reduce the chances of the unit tipping
over. Consult manufacturer’ s/vendor’ s instructions.
- When stepping on or
off of a camera crane, do so only after approval from the person
operating the unit. Stepping off of a balanced camera crane without
providing a counterbalance (e.g., another person to replace
the weight) can cause the arm to elevate rapidly and possibly cause
serious injury.
- Unattended camera cranes
should be secured to prevent movement of the unit (e.g.,
adding or removing manufacturer supplied weights from the weight
bucket).
- When handling un-coated
lead weights you should wear appropriate protective gloves and wash
hands after use.
- When operating camera
cranes, consideration should be given to wind, rain, extreme heat
and cold and other atmospheric conditions, whether natural or manmade,
which can affect the safe use of camera cranes.
