Alimak rack and pinion lift provides maintenance access to ammonium nitrate prill tower

Dyno Nobel Ammonium Nitrate Plant, Moranbah, QLD, Australia

An Alimak rack and pinion industrial lift is pre-designed into Dyno Nobel’s Moranbah ammonium nitrate plant, providing maintenance access to the 70m prill tower. Alimak utilised a crane to lower the lift into the existing tower shaft during installation.

The Dyno Nobel ammonium nitrate plant, located in Queensland’s coal-rich Bowen Basin, is part of Incitec Pivot’s $935 million Moranbah nitrate manufacturing complex. Included in the construction of the ammonium nitrate plant was the erection of a 70m prill tower to be used in the ammonium nitrate solidification process. Dyno Nobel specified the inclusion of an Alimak SE rack and pinion industrial lift into the design of the prill tower, in order to provide operations and maintenance staff with access to the tower’s top ‘penthouse’.

Alimak worked closely with Dyno Nobel, providing engineering support for the design of the tie-in points and landings, pit design and electrical supply requirements. Installation of the industrial lift proved challenging, with the lift to be installed within a pre-existing shaft area of the prill tower. To accomplish this, lift components were lowered from the 70m tower using cranes, while the Alimak installation team used a crane-hung ‘dog-box’ to access main tie-in points.

With a lifting height of 65m, providing access to the three landings of the prill tower, the Alimak industrial lift is used for general maintenance on a daily basis and accommodates extra personnel and equipment during heavy-usage shutdown periods.
