Platform Capacity Reduction
For Determining the Reduction In
Platform Capacity Due To
Attachment Of Movie Production
Equipment To Genie Boom
Platforms
Tip Over Hazard
Exceeding the recommended load
restrictions of the platform by
attaching movie production
equipment will result in the boom
becoming unstable and will result in
death or serious injury. Always
calculate the reduction of the
platform capacity caused by
attachment of more production
equipment.
Theory:
Platform maximum capacity is based on an evenly
distributed load. When movie production
equipment, such as light diffusion frames, set
lighting and camera mounts, are attached to the
front of the platform (entry side), the platform
capacity is reduced by more than the weight of the
equipment. The farther the equipment is mounted
from the center of the platform, the greater the
reduction in platform capacity.
Definition:
Center of Gravity (C.G.): The balance point of an
object. The point at which the entire weight of an
object is concentrated so that if the object is
suspended from that point, it will be balanced.
Reduce platform capacity according to the
following:
•
Attachment of power supply cables to the boom
reduces the platform capacity. Subtract the
total suspended weight of cables and rigging
from the rated platform capacity.
•
Subtract the load applied to the platform by the
attachment of additional movie production
equipment (as shown in Illustration 1) by using
the procedure and the Platform Capacity
Reduction Chart.
•
No additional load above rated platform
capacity is allowed. Personnel and payload
(with adjustment per Platform Capacity
Reduction Chart) must not exceed the load
shown in the appropriate Operator's Manual
and Decals for your machine.
How to use this chart
Follow these steps for each piece of equipment
attached to the platform.
1 Locate the weight of your equipment in the first
column on the chart. Always round up to the
next number.
