When paired with high-usage, articulated dump trucks (ADTs), they are at their best; the total cost of ownership for these trucks is low, and it can make them operate at peak performance.
A variety of factors can affect the performance of an ADT at a quarry. Many of the circumstances that could affect an ADT’s performance can be controlled by producers. Producers will need to make sure they have the right size ADT and the correct match to the machine when purchasing their next ADT.
The success of a producer with an off-road haul truck depends on the quality of maintenance and operating procedures. Aaron Kleingartner is the product and dealer marketing manager at Doosan Infracore North America.
Kleingartner states that equipment owners today are seeking to take advantage of technologies and best practices that will lower the cost of ownership. You can increase operating efficiency, prolong life cycles, and get the most from your ADT by focusing on the basic fleet strategies that directly impact your assets.
Recommendations
If an operation requires an off-road truck to transport short distances and has a medium-sized excavator, they might consider an ADT of 25-to-30 tons. A 35-to-40-ton ADT is best suited for large volumes that must be moved over long distances.
It is equally important to match the ADT size with the wheel loader or excavator. ADTs of similar size on the same haul road will often put less strain on your driveline, especially if they are deeply rutted.
Specifications for core articulated trucks should include engine horsepower, torque, and payload. Brakes system, load over height, vehicle width, and ground pressure are also important.
Partner options should be considered in relation to the site conditions. Match tire size and type to site conditions. Tire life will be reduced by hard-packed haul roads and sharp-edged rocks like shale. Additionally, minimizing tire sinking will reduce tire wear. A body liner is necessary to haul larger rocks and will prevent any damage or abrasion.
Safety requirements for your site are important. A lot of ADTs must comply with the Mine Safety & Health Administration and Occupational Safety & Health Administration regulations. To reduce the chance of accidents, equip your vehicles with the appropriate safety equipment.
Follow the recommended maintenance schedules. Lubricate daily in addition to other key maintenance intervals as indicated by manufacturers in their operation and maintenance manuals. To ensure the proper lubrication for expensive components, auto-lube systems can be beneficial.
Fleet management systems, also called telematics, are used to track maintenance intervals. Telematics can be used to check engine codes, which can improve maintenance and reduce guesswork.
Routine maintenance should include inspections of tires, drivelines, and structural members for damage. Inspect for any unusual sounds or vibrations, and look out for leaks. These issues should be addressed immediately to prevent unplanned downtime.
You can adjust maintenance intervals to suit specific conditions. Maintenance of double shifting is more important. Special oils and lubricants may be required for the protection of major components, such as the engine or transmission, in extreme temperatures.
Considerations
Operators can reduce excessive idle time by minimizing travel time between job sites and job sites. This will improve fuel economy. To increase profitability, operators should limit the idle time during ADT loading/unloading operations.
Training is essential for the safe and correct operation of ADTs. Operators can also learn the controls of an ADT faster by getting hands-on training. This will allow them to distinguish which features are more effective in particular applications.
Overloading is not a good idea. Owners and operators should realize that while there may be some short-term benefits to overloading ADTs in the short term, it will ultimately lead to higher repair costs and shorter machine lives. Overloading can also affect the life of your tires.
It is important to establish machine limits. ADT operators who have been trained in proper operation will be able to better understand the limits of ADTs and the consequences of pushing machines beyond their rated capabilities. Operators should be aware of stability limits when dumping or turning too fast and abruptly to avoid rollovers. A loaded dump body can also cause braking problems when going downhill. Accidents such as runaway trucks can cause serious injury and damage to your vehicle.
You should aim for optimal sight lines. There are many manufacturers that have addressed this issue with better fender designs, front-sloped roofs, and center-mounted taxis. Safety is just as important from the rear. Large, properly adjusted rearview mirrors, rearview cameras, and well-placed rearview mirrors can make backing up safer and help prolong ADT life.
Filling the Dump Box
It’s not a good idea to just pile things on top of each other when loading. It is important that the load be secured so that it can be stored later and transported without any problems. It is important not to fill the top portion of the dump box and ensure that the material is evenly distributed. A tarp is required in most states to further confine the load.
Make sure you practice safety
When it is time to dump the material, be careful. There is a lot of material being thrown around, so safety and safety must be your top priority. Here are some basic tips:
You can use the dumpbox on any flat surface, including the ground.
Spotters are a great resource and you should follow their instructions via headsets or hand signals.
You should have a space that isn’t accessible to other people or equipment.
It is a good idea also to meet with the site foreman in order to clarify what they require and expect. You might need to follow additional safety guidelines.
Keep your truck in good shape
Your truck won’t perform well no matter how careful you are. Regular inspections are necessary and you should take your dump truck in to be serviced. You can either repair the truck yourself or take it to the fleet owner if you find damage. You don’t want to stop people from getting on their nerves.
Proper operation is key to safe and efficient dump truck usage. Synergy Equipment can help you with any questions or concerns.
