DANGER WARNING CAUTION
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/s-2 (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/s-2 (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.
