Access Systems
Access to Boom, Mast & Gantry

The walkways, ladders and platforms designed and supplied on many of the draglines operating in Australia do not comply with Australian Standard 1657. CMP Engineers has designed compliant systems for Marion 8050 and BE 1370W draglines and the designs could be adapted to other models.

The goal of the new designs was to eliminate all rung ladders and to install stairs wherever possible. In some places it has been necessary to use step ladders. Accelerometers were used to determine the dynamic loads which was combined with finite element modelling for fatigue life determination on the walkway structures. The resulting designs have proven to be highly resistant to fatigue failure.
