HAULING commonly used in mining so its easy to mismatch equipment Bereika says 3 Identify jobsite restrictions Are there any width height or maneuverability restrictions that may impact an ADTs ability to fully perform Loading under a hopper for example will usually mean there are width and height restrictions and some larger ADTs may not physically fit in the space Built for maximum maneuverability ADTs are designed to adapt to uneven terrain through use of a hinge connecting the cab to the body which allows the truck to flex This feature also assists in keeping all six wheels in constant contact with the ground while traveling over loose or compacted soil banks material pilings or rocks common in mining or quarry jobsites Due to their massive size mining and quarry projects can involve long drives on congested haul roads and operations in confined staging and dump areas Select an ADT with a tight turning radius which can help decrease the time it takes for operators to position the trucks for loading and unloading 4 Choose tires carefully Tires are always a concern in quarries and mines because of the risk of sidewall damage and lower tread life due to operation on hard packed surfaces Bereika says so choose tires carefully to minimize costs The right tires contribute significantly to an ADTs tractive force which is determined by the tread design remaining tread life and tire inflation along with the ground conditions at the site One of the most important tire decisions is whether to use E3 or E4 tires The most common ADT tires are two star E3 radial tires however E4 tires offer better sidewall protection for sites that have sharp rocks and may serve as an upgrade in those environments Hard packed roads cause shorter life for all tires but individual tire manufacturers can inform users about which rubber compounds will provide longer life 5 Extend ADT life with dealer support Make sure you understand all of your ownership costs and the expected lifetime of ADT components as they may be different from equipment you currently own Since ADTs are used off road and are subject to severe duty component lifetimes may be different than typical mining equipment This is why educated and dependable product support is critical Before purchasing an ADT choose a dealer that has product specialization and trained mechanics offers great response times and has good parts stock I would advise sitting down with an ADT dealer and having a discussion about the type of work youll be performing required scheduled maintenance a preventive maintenance program and major component rebuilding Bereika says When properly evaluated and matched to the type of work youre performing the return on an ADT investment will be proven out in daily performance lower ownership costs and longer life P Q ÈÇÓ ÇnÎäÊ ÊUÊ ÈÇÓ Ó Ê 8ÊUÊ777 LAND RESERVES PURCHASE Natural Resource Partners L P a publicly traded master limited partnership is interested in purchasing land surface and mineral rights and minerals processing infrastructure NRP has continued to grow its business through investment in mineral rights and reserves and most recently through the acquisition of a minority equity interest in OCI Wyoming L P one of the worlds largest producers of natural soda ash NRP focuses its investments on the acquisition of long life assets such as actively mined aggregate reserves Investments primarily involve the sale leaseback of reserves for future royalty payments All cash purchases NRP has the ability to close and fund quickly Funds may be used for recapitalization partner buy out operating capital equipment purchases plant expansion etc NSSGA Member Acquisitions@ nrplp com Toll Free Phone Fax 866 973 8886 www nrplp com www pitandquarry com June 2013 PIT QUARRY 45
