BENEFITS OF CONYMET TRUCK BODY - HE SERIES

1.- Mine Customized Design (MCD):

Unique body design tailored to each mine, exclusively engineered under specific Geological and Techno-Mechanical conditions to reach maximum load optimization, developed with state of the art software of Photometric and Finite Element analysis.

2.- Body weight reduction
      up to a 50%:

Conymet Highest Efficiency design (HE Series): Manufactured with high technology steels with an operating function limit of 135 kg/mm2, traction resistance of 162 kg/mm2, and 28% elongation.
Strategic Alliance with Nippon Kokan (NKK – Japan): Highest quality and standards of steel mixtures (HE Series utilizes between 4 and 7 different types of steel, depending on mine specific conditions).

3.- Payload capacity increase up
      to a 16%:

Higher production capacity and maximum mineral load optimization, therefore 7 trucks will deliver the production of 8.

4.- Cost per ton reduction
      up to a 18%:

Conymet body engineering improvement in the load distribution by axle based on mine operational conditions (flat ground or with inclination +/- 10%, full and empty truck), achieves the remarkable savings in tires, suspension, differentials, traction, engines, etc.
Higher body payload capacity also gives the option of decreasing the number of trucks, while maintaining the same production, therefore achieving relevant savings in maintenance, tires, parts, fuel, labor, etc.

5.- Improves Axle load distribution
      and load placement:

Conymet High Efficiency body (HE Series) improves the load distribution by axle for every mine condition (flat road or with inclination +/- 10% degree, empty/full truck).
This improvement in axle distribution limits front axle overload up to but not more than 2%.
The placement correction achieved by Conymet design allows also centering the load cone properly.

6.- Safer load conditions:

Body with lower sidewalls and wider floor improves load conditions and decreases the load cone height, therefore the body design would obtain a lower center of gravity and thus improve the stability and ergonomics of the truck.
Lower sidewalls decrease typical damages sidewall borders receive when loading (Loaders and Shovels). Additionally it facilitates the exit of the shovel dipper since the sidewall inclination angle makes the rear part of the sidewall even lower.
Higher payload capacity achieved with a lower Fill Coefficient (0.8) minimizes unwanted discharge of the load while being transported.

7.- Unique modular
      assembling system:

The Hinge Assembling Kit (HAK) system developed for Conymet HE Series, allows for complete assembly within 2 days.

8.- Longer durability:

Conymet HE Series is not a disposable body like the traditional “light design” currently on the market. Under normal maintenance conditions, its life and durability is longer and superior than standard truck bodies.

9.- Award Winning Technology
      Innovation (Year 2000):

National Mining Association Awarded Conymet truck body - HE Series (Patent Pending).

10.- ISO 9000 certified:

Quality certification of Conymet Manufacturing Processes (Design, manufacturing, welding procedures, assembling and after-care maintenance) guarantees higher performance and consistency.

11.- Industrial Duty Free Zone:

Conymet has officially become the first Private Company to be awarded with the extension of a governmental Duty Free Zone in Chile. This means that Conymet Facilities in the north of Chile (I Region) are a formal Industrial Duty Free Zone (Import/Export tax free).

A fact highly relevant in terms of Production Cost (all Conymet materials are imported from Japan, Australia and the US). It also provides an advantageous profile for implementing a Duty Free Factory to Export, with unique competitive capabilities, all Conymet products from Chile to overseas (USA, Pacific Rim, South America, North America, etc).

 

Economics Benefits of Conymet truck body – HE Series
Example for Komatsu truck 830E at TOQUEPALA Mine:

Higher Payload Capacity:
237 tons – 204 tons = 33 tons/truck
33 tons/per truck x 18 trucks x 0.85 of fleet availability = 504.9 tons/per fleet
504.9 tons/per fleet x 60 cycles per day per truck = 30,294 tons/per fleet per day.Mine production increase: 16,1%.Lower Maintenance cost:
Production increase (tons): 237/204 = 16,1%
C1 = Current maintenance cost
TM1 = Tons production with current standard body
TM2 = Tons production with Conymet body – HE Series
C2 </= C1 :
Maintenance cost also decreases in:
Tires, wear package maintenance, fuel, engines, suspensions, transmissions.
TM2 = TM1 x 1.161
TM1 = TM2/1.161Maintenance cost decrease in:
C1/TM1 - C2/TM2 = C1 ( 1 – 1/1.161) = 13.87% If we also take into consideration that a lighter body produces savings in: cost of tires, wear package maintenance, fuel, engines, suspensions, transmissions, etc.
And if we also consider than higher capacity body can also saves in maintenance cost, fuel, labor, etc. based on the option of decreasing the number of trucks, while maintaining the same production, Conymet HE Series achieves savings up to an 18%
