Refurbished Dump Truck Performance | Heavy-Duty Operations Insights
Whether on a mine road or a busy building site the trucks are not given much mercy. On these roads lots of dust gets into small gaps. Also on these roads lots of mud gets in between the tire tread and that causes big problems. But not only the road on a building site or a mine is very challenging, also the loads that the truck has to transport are changing very fast.
Sometimes within a week or even within days the truck is carrying sand and then suddenly it is carrying stones and boulders. Therefore a refurbished dump truck must be ready for that. It must look nice on the photos, but the most important thing is that the refurbished dump truck is able to carry stuff, to climb up and down hills, to dump the load, to brake properly and to do it all over and over again.
Why Does Dump Truck Performance Matter in Heavy-Duty Operations?
There is a direct correlation between dump truck performance and daily cost. One truck sitting idle next to a loader could cost a company as much as it is costing to have several workers and pieces of equipment sitting idle. And that is not a theory, it happens on construction sites all over the country and can cost a lot of money in a short period of time. For heavy-duty applications, the most important thing to a buyer is how long a truck will operate on a daily basis and give them the performance they need even on rough roads and tight schedules.
Power, Torque, and Daily Hauling
A good refurbished dump truck is characterized by a lot of pulling power. Above all, its torque when driving with a loaded vehicle on a slope is crucial. Also on wet soil or on loose gravel for example. An 8×4 mining dump truck is usually used for the heaviest applications, as this type of truck has the most load capacity and the best support for the load on uneven terrain. On straight roads this may not be so obvious, on bad site road conditions it is vital.
Stability under Harsh Site Pressure
Most site work is hard work. Load and drive to the dump, dump the load and then return to the start. Day in and day out. The chassis, brakes, suspension and tires are subjected to constant pressure. If the truck does shake when loaded, or the brake feel is ‘spongy’ this is a warning sign to the cost of buying the truck below its true worth. A cheap truck can quickly become a costly mistake if it cannot operate in a stable manner.
What Makes a Reliable Refurbished Dump Truck?
A reliable reconditioned dump truck is more than just a used dump truck with a fresh coat of paint. Reconditioned dump trucks are taken apart part by part and thoroughly inspected and repaired as required for all major components including the engine, gearbox, chassis frame, cabin, electrical wiring, brakes, tires and hydraulic system. It seems obvious but the basic checks can save a lot of problems in the long run.
Engine and Chassis Condition
While engine power is somewhat important, the true condition of a vehicle is much more critical. Liangshan Tuoda presents buyers with a variety of refurbished dump trucks of the common 6×4 and 8×4 configuration, with an output of around 336HP to 420HP, thus enabling the driver to optimize his vehicle for the specific road, his particular type of loads as well as for the duration of his work.
Hydraulic Lifting System
Hydraulic system is an often-neglected component of your truck. Just because your truck is driving well does not mean that it will dump loads well. Make sure that the lifting cylinder, oil pressure, seals and lifting speed are adequate. Smooth lift to upright is required. A system that jerks or leaks will soon turn unloading of your truck into slow and unsafe operation.
How Does Payload Capacity Affect Real Work?
A number for payload capacity changes the whole work plan. It determines how often you have to make a trip, how much fuel you will need for your trips, how long your tires will last and how much pressure your frame will be under. So even though a number is a number, a mining dump truck with stone as payload will be working under far more stress than a truck loaded with loose soil and same number as payload capacity.
Match Load to the Site
For quarry applications the payload must match the weight of the stone and the slope of the roads. For waste transfer work the body size is more important. By overloading a refurbished dump truck every working day the truck maintenance costs will increase. The costs will often first be visible in the form of worn tires.
Choose Configuration with Care
While an 8×4 may be suitable for the heavier hauling, a 6×4 could be better suited for the short driving distances and tight sites that you described. The choice between a 6×4 and an 8×4 would depend on a number of factors including the average driving distance per trip, the turning area required at sites, the size of the loaders being used and finally any local load restrictions that may apply. While bigger is better when it comes to trucks, a smaller truck that can keep working all the time could be the smarter buy.
How Should You Compare a Refurbished Dump Truck and a Used Dump Truck?
A used dump truck is usually sold as it is. A refurbished dump truck on the other hand is checked, repaired, has parts changed and is road tested. For overseas buyers this is important, since repairs after delivery are expensive in terms of time and money.
Inspection Records and After-Sales Support
Liangshan Tuoda International Trade is a China company which specialized in exporting used heavy trucks and new trucks in stock. Our main trucks export include dump trucks, tractors, flatbed trucks, concrete mixer trucks and other big vehicles. At Export Used Trucks website, we also test trucks, post review of trucks, assist in export trucks to customers, assist in matching resources for customers who want to buy used trucks and provide after sales services to customers. The process of buying used trucks also means that buyers have to deal with a lot of papers and documents in importing used trucks, the shipping process, getting spare parts for used trucks and providing services to used trucks after sales.
Refurbishment Value
Don’t judge a car by its paintwork. Find out what was checked and what was replaced. Test the engine, gearbox, brakes, hydraulic parts and chassis first. The outside may look okay but it’s the working parts that really matter.
What Truck Maintenance Keeps Performance Stable?
Ongoing maintenance on a dump truck will help to extend the useful life and ensure that the truck continues to function at peak levels without a sudden decline in performance even for a well prepared refurbished truck. Rock, mud, high temperatures, dust and long periods of idle all place great amounts of stress on a dump truck and that is why good maintenance is hard work but saves a lot of money in the long run.
Key Maintenance Points
Check oil level, oil air filters, coolant, hydraulic oil level, brake air pressure, tire tread depth, steering box play any signs of wear on fluid & wiring hoses. Drivers behavior also plays a big role in the life of the truck. Aggressive driving such as hard braking, sudden dumping, overloading & harsh shifting can drastically reduce the life of the truck. Driving carefully may seem insignificant but is crucial at many work sites.
Conclusion
A refurbished dump truck can also be used for very heavy-duty work. The most important thing is that it is in good working order. A good dump truck has a good engine, sufficient payload, good brakes, stable hydraulics and regular maintenance. When buying a truck, it is wise to compare the inspection reports of several trucks, the type of trucks and the services that the supplier can offer. The refurbished dump truck page also helps buyers to choose practical options.
FAQ
Q1: A refurbished dump truck for heavy duty use?
A: Yes, if key components have been checked, repaired and put to test before the truck is being sold.
Q2: What affects dump truck performance the most?
A: The dump truck’s performance is affected by the engine’s torque, payload, brakes, hydraulic system for the hydraulic lifting, tires, and the driver.
Q3: Is a mining dump truck different from a standard dump truck?
A: Yes. The mining dump truck needs extra support for the extra heavy loads as well as better traction to handle on the rough mining roads.
Q4: Why is the payload capacity of a truck so important when selecting a unit?
A: Payload capacity affects how many trips you can take, fuel costs, tire wear, frame stress and the potential for costly repairs.
Q5: What is the main difference between a refurbished and used dump truck?
A: A refurbished truck goes through an inspection, repair, parts replacement and test prior to its sale.
