There are certainly benefits from outsourcing your tyre maintenance programme to a specialist provider.However, this solution isn’t viable for every operation. Perhaps geography presents a challenge or there is simply a lack of suitably skilled tyre repair service providers in the region. For these reasons and more, we are often asked to assist clients with establishing and developing an in house tyre repair program.
This case study outlines a recent project undertaken by the Monaflex team and particularly highlights the commercial advantages.
Client: A privately owned mining and civil contracting company.
Status quo: Tyre repairs sub-contracted off site.
Objective: Support the corporate self-sufficiency objective by establishing a dedicated, centrally located tyre repair program.
Available infrastructure: Shared work space bays within a common workshop.
With this client we were essentially starting from scratch and therefore provided comprehensive support on three levels…
Our client has 3 remote open cut mine sites in Asia.
The conditions are austere. Deep, cramped pits with narrow haul roads and tight switch-backs. Underfoot conditions, particularly at the base of the pits, are abrasive.
ADT’s have significant advantages over rigid dump trucks in rocky and uneven terrain. The articulated steering allows for a tighter turning radius and offers superior manoeuvrability and stability.
Being 6-wheel drive with differential locks, an ADT also has far better traction and accessibility than a rigid bodied truck.
Tyre sizes: 29.5R25
Tyre brands/ specifications: Bridgestone VLTS E4 E2A, Triangle TB598, Maxam MS405
Inflation pressure, (cold): 110 psi. This is 20 psi greater than the OEM recommended pressure and likely to account for impacts and crown damage. Cold pressures should be reduced to 90psi and checked a minimum of once per week.
Mean Tye Life (Scrap Hours): Est. 3,500
Primary Failure Modes: Sidewall rock cuts, Crown rock cut separations.
Tyre Damage Area Ratios: Sidewall – 75%, Crown – 20% , Shoulder – 5%.
The impact of an effective repair program on this operation is significant.
In year 1, a minimum of 230 damaged tyres will go back into service. This conservative estimate is based on 35% of tyres assessed being deemed suitable for repair.
In new tyre value terms, repairing tyres yields a YOY saving of $184,000 or 92 tyres!
Aside from the direct value generated, the following advantages were also unlocked:
The current tyre repair program is being extended to cover the TBR fleet using a Monaflex TRM system.
