Safety Caution
(10) Be careful with radio wave conditions.
Since the radio-control system uses radio
waves, it cannot avoid influences of
electromagnetic interference, radio interference
and exogenous noise. Such influences may
hinder the radio wave transmission, stopping
the crane operation.
Stopping of the crane during the operation may
cause dangers. It is especially dangerous
during a swing operation of the crane. Pay
attention to the following when operating the
radio-control system.
・
It is dangerous to operate the crane under
conditions with low radio wave
transmission, especially during a swing
operation of the crane since the crane
intermittently moves. Before starting the
operation, confirm that there is no problem
in the crane operation under no load
condition.
・
Too large a distance between the
transmitter and communication unit may
not only hinder the radio wave transmission
but also increase influences of noise.
Normally, operate within the operating
radius of the crane.
・
Obstacles such as wire nettings and metal
doors between the transmitter and
communication unit may hinder the radio
wave transmission.
・
Use manual control operation under
unfavorable radio transmission conditions.
・
Noise from a vehicle’s air-conditioner used
during the operation may cause an
intermittent crane operation. Refrain from
using an air-conditioner when its noise
influences the radio-control operation.
・
Noise from an approaching motorcycle to
the operation site may cause an
intermittent crane operation. Confirm that
there is no motorcycle approaching during
the operation.
