Falling Object Protection Structure

from Wikipedia, the free encyclopedia
Driver's cab with FOPS protective structure

Falling Object Protective Structure ( FOPS for short) describes a protective structure of driver's cabs against falling objects from above and represents an extension of the roll-over protection (ROPS). For this purpose,additional, reinforcing frame and grid elements are builtinto the cabs of construction machines . In the event that an object falls on the driver's cab, it is only slightly deformed and the construction equipment operator is effectively protected.

This protective structure is primarily used for construction machines that are active in the mining industry ( mining or open-cast mining ) or in demolition. When developing new driver's cabs for these vehicles, the effectiveness of the protective structure must be proven by means of standardized test procedures.
