• Carry out the following tests with the carrier
attached to the body or in a similar state.
(a) Tensile strength test
(clamped tire-carrier)
Apply the following load face down at the center
of the disc wheel with a tire attached to the
carrier.
(hoisted tire-carrier)
Apply the following load face down via the
hoisting plate.
As a result of this test, carrier components must
be free from detrimental deformation.
(b) Hoisting strength test
(hoisted tire carrier)
Fix the hoisting plate, and apply the following
torques on the carrier.
As a result of this test, carrier components must
be free from detrimental deformation.
(c) Operating durability
Hoist a tire of maximum allowable weight,
tighten to a torque of 49 Nm, and then winch
down. Repeat this series of operations 200
times. (This test needs be carried out contin-
uously.) As a result of this test, operation must
remain uninterrupted and carrier components
must be free from detrimental deformation.
(d) Looseness resistance
Increase and decrease vibrations of 1 g (9.8 m/
sec2) (need not be 1 g during resonance
vibrations) and 8.3 Hz to 50 Hz (500 to 3,000
times per minute) on the supporting device in
the vertical direction of the carrier mount
continuously for one hour taking at least 5
minutes for each reciprocal movement.
As a result of this test, the carrier device must
be free from detrimental looseness.
P=W × α × β
P: Test load
W : tire of maximum set weight
α : Load multiple of 2.5
β : Required safety ratio of 1.3
P=(Po × γ ± W × α) × β
P: Test load
Po : Load applied on chain by tightening
torque during standard tightening
W : tire of maximum set weight
α : Load multiple of 2.5
β : Required safety ratio of 1.3
γ : Load multiple of 1.5
T=To × γ × β
T: Test torque
To : Standard tightening torque
