Snorkel TL39T - Manual (Page 75)

► aerial platform
a mobile device that has an adjustable position
platform, supported from ground level by a
structure.
► ambient temperature
the air temperature of the immediate
environment.
► ammeter
an instrument for measuring the strength of an
electric current in amperes.
► authorized personnel
personel approved as assigned to perform specific
duties at a specific location.
► base
the relevant contact points of the aerial platform
that form the stability support (e.g. wheels,
casters, outriggers, stabilisers).
► boom
a movable cantilever beam which supports the
platform.
► center of gravity
the point in the aerial platform around which its
weight is evenly balanced.
► chassis
the integral part of the aerial platform that provides
mobility and support for the booms.
► fall restraint
a system that is used while working on a boom
lift within the bound aries of platform guardrails
to provide restraint from being projected up ward
from the platform. This system includes a harness
or belt, lanyard, and a lanyard anchor. Federal
OSHA, ANSI, and Snorkel require the use of
additional fall protection beyond the platform
guardrails on boom supported aerial platforms.
► fall or ground pressure
the maximum pressure, expressed in pounds per
square inch, a single wheel concentrates on the
floor or ground.
► gradeability
he maximum slope that the aerial platform is
capable of travel.
► ground fault circuit interrupter or
residual current detector
a fast-act ing circuit breaker that opens to stop
electrical circuit flow if it senses a very small
current leakage to ground. Also called GFCI or
RCD. The GFCI/RCD is used to protect personnel
against a potential shock hazard from defective
electrical tools or wiring.
► guardrail system
a vertical barrier around the platform to prevent
personnel from falling.
► hazardous location
any location that contains, or has the potential to
contain, an explosive or flammable atmosphere
as defined by ANSI/NFPA 505.
► jib boom
a boom assembly located between the main
boom and the platform.
► level sensor
a device that detects a preset degree of variation
from perfect level. The level sensor is used to
sound an alarm if operating on a slope greater
than the preset value. It may also (depending
on the machine) prevent the it from operating
further until it is brought back within the preset
parameters.
► lower controls
the controls located at ground level for operating
some or all of the functions of the aerial platform.
► main boom
a boom assembly lo cated between the turn table
and the platform or jib boom. The main boom
includes the base, intermediate, and tip boom.
► maximum travel height
the maximum platform height or the most adverse
configuration(s) with respect to stability in which
travel is permitted by the manufacturer.
► Minimum Safe Approach Distance
the minimum safe distance that electrical
conductors may be approached when using the
aerial platform. Also called MST
► operation
the performance of any aerial platform functions
within the scope of its specifications and in
accordance with the manufacturers instructions,
the users work rules, and all applicable
governmental regulations.
