ROPS CAB TESTING

Vertical, Lateral, & Longutudinal Testing for ROPS Cabs

ROPS testing entails mounting a ROPS cab specimen to a representative machine chassis specimen, and fixing the entire assembly to a rigid test bed, then loading from the side (lateral load), from the top (vertical load),and from the front or rear (longitudinal load).

ROPS Lateral Test

ROPS Lateral Test

The Lateral test requires energy absorption and maximum load support as a function of machine mass, without violating the operator space.

ROPS Vertical Test

ROPS Vertical Test

The Vertical test requires the cab to support approximately 20 times the machine weight without violating operator space.

ROPS Longitudinal Test

ROPS Longitudinal Test

The Longitudinal test requires the test specimen to absorb energy as a function of machine mass without violation of operator space.

Testing can be done at ambient temperature, or at -18C. If tests are done at ambient temperature, ROPS-grade materials must be used in the construction of the ROPS. This requirement is generally waived if cold-temperature tests are conducted. However, material physical & chemical properties must still be monitored to assure similarity to that which was tested, but longitudinal charpy V-notch energies are not required.
