Thwaites Limited puts Safety First
It is the policy of Thwaites Limited to promote safety in the
operation of its machines and to create a general awareness of
site safety and safe working practices for the operators of its
machines.
This Operator’s Instruction Manual is intended for both new
and experienced machine operators. It should remain with
the machine at all times. All operators should be aware of its
location and contents.
It is important that all operators are fully trained and familiar
with the machine and that they have read and understood the
information contained within this book before they attempt
to operate in the site conditions for which the machine was
designed.
This book details practices and operations which Thwaites
Limited recommends. DO NOT operate this machine in ways
other than those detailed within this book.
This machine is designed for customary construction site
operations, and the transportation of bulk materials commonly
carried on such sites; that is their ‘intended use’. Under certain
controlled conditions the dumper may be used for towing
wheeled loads.
Due to the varied nature of the operation of site dumpers and
the absence of an agreed test standard, any gures quoted
by Thwaites in relation to vibration values and exposure are
for reference purposes only. It is the responsibility of the
employer to assess vibration exposure based on the actual site
conditions, and operating practices, at the point of use.
Hand Arm Vibration - The daily exposure Action/Limit Values
of between 2.5 - 5.0m/s2 (A8) are unlikely to be exceeded in an
eight-hour reference period.
Whole Body Vibration - The daily exposure can only be
accurately determined at the point of use. This exposure must
be managed in respect of the Action/Limit Values of 0.5 and
1.15 m/s2 (A8) respectively.
Employers should not rely solely on published vibration
gures when undertaking risk assessments. Depending on the
site conditions, cycle times may need to be adjusted in order
to reduce operator exposure levels.
Vibration values based on typical duty cycles are available
on request from Thwaites. These may be used for reference
purposes only.
