Lifting the game
CASE STUDIES
The Pakka Jacks system has revolutionized machine maintenance on mine sites across Australia, for a wide range of machines and procedures.
This patented system has been developed and tested for over a decade, in some of the harshest mining conditions in the world. We have successfully completed projects on over 80% of all major open-cut machines in Australia.
In that time, the system has established itself as vastly superior in terms of safety, speed and cost-effectiveness. It has completely changed machine maintenance for some of the world’s largest mine site operators.

Slew Bearing
Change-Out
Newcrest
Telfer WAJune 2012
The digger slew bearing surfaces required a laser survey to assess potential damage, before the bearing was replaced.
The digger was split and the old bearing removed 14 hours after the team arrived on site. The laser survey was conducted, revealing that the lower bearing surface was 0.022 inch out of specification, and required reclaiming.
A specialist machinist company was promptly contacted and the bearing surface reclaimed in position. Within 30 hours of discovery of the lower bearing surface problem, it had been resurfaced and the bearing change recommenced.
COMPARISON
- Streamlined workflow
- Laser survey accurate to 0.0004 inches
- Greatly reduced downtime
- Greatly reduced labor
- Improved safety
- No suspended loads
- No dual crane lifts
RESULTS
Project time: 4 days (normally 8 to 13)
Labor: 6 workers per shift (normally 12 to 14)
Cost: Savings were huge. The sheer speed of operation slashed costs across the board.6
DAYS SAVED2544
MAN-HOURS SAVEDThe Pakka Jacks system allowed the bearing surface reclamation in situ, dramatically reducing the project time.

Hitachi EX8000
Track FrameXstrata
Hunter Valley NSWMay 2012
The final drive shaft had snapped in two and had bent the drive transmission mounts on the track frame.
The machine was located at the bottom of the mine area and couldn’t be moved. A customized jacking pad was prepared and the 893 ton machine raised. Customized side frame removal rails were set up and the damaged side frame was sent away for repairs.
Mine supplied fitters were able to use the downtime to safely carry out much needed maintenance on various components, an extraordinary benefit of the Pakka Jacks system. The refurbished track frame was transported back to the site and fitted.
COMPARISON
- Ability to access difficult location
- Other maintenance possible during downtime
- Greatly reduced downtime
- Greatly reduced labor
- Improved safety
- No suspended loads
- No dual crane lifts
RESULTS
Project time: 4 days (normally 10 to 15)
Labor: 6 workers per shift (normally 10 to 12)
Cost: Savings were huge. The ability to perform additional maintenance work added enormous value.9
DAYS SAVED1080
MAN-HOURS SAVEDThe versatility of the lifting system meant that the work could proceed in situ. The additional maintenance was also an enormous cost saving.

Terex RH340
Slew BearingDowner EDI
Bowen Basin QLDSeptember 2011
Inspections on the slew bearing indicated that deflection was increasing rapidly and the machine was stood down.
A team of 4 Pakka Jacks technicians was deployed with the equipment, arriving on site 24 hours after the phone call. After mandatory inductions, the job was completed in four 12 hour shifts, only 70 hours from the decision to stand it down.
COMPARISON
- Rapid response
- Greatly reduced downtime
- Greatly reduced labor
- Improved safety
- No dual crane lifts
- Craneage: 1 x 22 Ton crane (normally 2 x 110 Ton)
- No suspended loads
RESULTS
Project time: 2 days (normally 5 to 10)
Labor: 6 workers per shift (normally 10)
Cost: Savings were huge. Craneage costs alone were slashed.5
DAYS SAVED1128
MAN-HOURS SAVEDThe streamlined workflow got the RH340 back to work in only 70 hours.

P&H 2800XP
Rope Shovel
De-Decking for
Major OutageBHP Iron Ore
Newman WAJanuary 2009
The rope shovel needed de-decking to perform a major outage lasting 6 weeks.
The process required the car-body to be walked out from under the upper deck, leaving the deck lifted at a set height for the duration of the outage.
COMPARISON
- Greatly reduced downtime
- Greatly reduced labor
- High side loading capacity
- Improved safety: No need for over 70 inches of packing plates around the machine.
- No suspended loads
- No dual crane lifts
RESULTS
Project time: 10 hours (normally 40 to 48)
Labor: 3 workers (normally 10 to 20)
Cost: Savings were huge. The Pakka Jacks system meant that the lifting system also fully supported the load at every stage of the lift.34
HOURS SAVED408
MAN-HOURS SAVEDThe fact that the lift units were also the certified stands for the duration of the project, meant that set-up and commissioning times were slashed.

Slew Bearing and
Major MaintenanceBHP Billiton
Hunter Valley NSWThe BHP Billiton owned Liebherr digger required a number of significant change-outs and repairs. The Pakka Jacks system allowed all work to be carried out simultaneously.
SCOPE OF WORK
- Slew ring change out
- Valve Bank change out
- Swing box change out
- Motor change out
The entire machine was raised 23 inches, additional stands were placed under the car body to allow for side frame removal, which also made it possible for all phases of the outage to proceed simultaneously.
COMPARISON
- Multiple works run concurrently
- Greatly reduced downtime
- Greatly reduced labor
- Improved safety
- No need to remove attachments
- Allowed work areas to continue
- No dual crane lifts: Minimal craneage required overall
- No suspended loads
RESULTS
Project time: 14 days (normally 24 to 30)
Labor: 6 workers per shift (normally 10)
Cost: Savings were huge.14
DAYS SAVED4224
MAN-HOURS SAVEDAllowing multiple jobs to proceed at once, safely, meant that a large and complex project was completed in less than half the time.
