created to make this work more efficient and safe. In 2007 Pakka Jacks was established as a separate enterprise and TFP started preparing the system for the international market. The company has successfully completed work for most of the major mining companies, including BHP Billiton, Rio Tinto, Newcrest, Glencore, Sojitz Minerva Mining, Theiss Australia Mining and Coal & Allied.
Pakka Jacks perform two critical roles; lifting and supporting.“ The patented automatic mechanical packing mechanism is the key to this incredible combination. At every point in the lifting operation, the load is supported. Failure of any component will result in a maximum drop of 0.25 in. This simple fact has enormous implications for site work, given that it is illegal( and dangerous) to work under suspended loads.”
Each Pakka Jacks unit has four packing mechanisms, allowing for three units to be taken out of commission under load. Each unit also has capacity for secondary hydraulic input in the case of primary hydraulic pump failure.“ The load is fully supported at every point of the lifting operation, this has huge implications for site safety and project cost and duration. From 165 t to 2,200 t, the Pakka Jacks lifting systems offer a huge range of capabilities across a broad spectrum of applications.”
The Pakka Jacks lift units are self-contained, with all lifting hydraulics and packing mechanisms packaged in a solid, compact casing with excellent intrinsic stability. Certified lifting lugs, control input points and secondary hydraulic input points complete the general description of the lifting units. The system is controlled from a fully enclosed, air-conditioned control console.
