Safety Rules - Rops Judgment - Case CX350D Service Manual

Safety rules – ROPS judgment
1. Purpose
Judge whether or not the model is compliant with ROPS by the ROPS criteria.
Compliance with ROPS is highly dependent on its deadweight and boom.
The model has passed the ROPS test for its deadweight with all selectable options installed (as of 2009).
However, the judgment is required because its deadweight or boom position may go beyond the assumption de-
pending on derivative or order conditions.
2. ROPS criteria
Weight
For each class, the following weight shall not be exceeded.
If the weight is exceeded, a cab may become damaged in case of a rollover, causing the operator to die or become
severely disabled.
It is not applicable beyond the criterion.
The ROPS-compliant model shall not exceed the weight shown in the table.
(The following weight is shown on the decal in the ROPS cab.)
Gross body weight
32000 kg (70547.92 lb) or less
40000 kg (88184.90 lb) or less
Boom position
Warning
• If you make such modification as lowers the boom position, ROPS is not applicable.
• Consultation with us is required whenever it is assumed that the boom position is lowered by modification.
• The range of change in the boom position cannot be determined uniformly.
It is not applicable if the position overlapping with a cab on the side view (mark * in the figure) is lowered significantly
as compared with the standard model (standard arm), within the maximum digging radius with the bucket tip on the
surface of the ground.
Moreover, it cannot be said that the 24-ton model, close to the limit weight, with a cab that can bear up to 31-tons and
the 21-ton model with the same cab are the same in the degree of influence.
