The Safe Working Load (SWL) of the Frog 3 is the total load of
passengers and luggage. SWL = 330 Kg(727 lbs).
The Allowable Passenger Load of the Frog 3 is the total
passenger load to be placed on the seats. APL = 270Kg (594
lbs)
Background: The safe working load (SWL) is relevant to the
selection of lifting apparatus and the approach to periodically
testing the unit to ensure integrity. The passenger load is
important, as this defines the ‘moving mass’ for which the
design of the Frog 3 suspension system is matched.
Frog 3 design assumes that 3 persons of 90Kg (198 lbs) are
loaded onto the seats, equivalent to 270 Kg of ‘moving mass’.
In addition to this, each passenger carries 20Kg (44lbs) of
luggage placed on the floor, 60 Kg of ‘static mass’. The
combined load is the SWL of 330 Kgs (727 lbs).
