• How can the traction capability of the off-road lowbed trailer be enhanced?
  The traction capability of the prime mover can be enhanced with the addition of weight to the prime mover's rear axle. This is achieved by mounting a steel or concrete weight on the prime mover chassis rails. The retro-fitment of such a weight is a relatively simple exercise, should it be required.
• What is cathodic protection?
  Cathodic protection is used to protect steel from corrosion which is caused when two dissimilar metals are submerged in an electrolytic substance such as water, soil, or concrete. This type of metal conducting path between the two dissimilar metals allows a pathway through which free electrons move from the more active metal (anode) to the less active metal (cathode). If free electrons from the anode do not reach active sites on the cathode before the arrival of oxygen, ions at the active sites can then recombine to produce ferrous hydroxide, i.e. rust.
• What is 'deflection limiting volume' in relation to ROPS & FOPS?
  Also known by the term DLV, this defines the volume occupied by the person that may not be penetrated by a protective structure, in accordance with the prescribed ISO 3164 standard.
• What quality assurance standards are in place for ROPS & FOPS?
  All ROPS & FOPS are certified at both the design and production stages, and includes design testing of a prototype and/or design verification by a professional engineer in terms of the prescribed requirements.
• Do the requirements for protective structures vary for surface and underground mining environments?
  For surface operating vehicles all requirements are compliant with ISO 3449:2005 standards or equivalent. Although the same standards apply for underground mining environments, all FORCE requirements must be doubled in respect of vehicles operating under a non-supported roof.
• What is the definition of Finite Element Analysis?
  This method is used to test that FOPS structures conform to the prescribed performance standards. The bottom frame and attachments to the machine frame are designed to remain elastic during testing, while the roof structure is designed to either remain elastic, or to deform plastically within the specified limits.
