The electric drive vs mechanical-diesel debate has been an ongoing one in respect of rigid haulers, especially at the larger end of the payload scale. Diesel-electric trucks were initially developed as a solution to the shortcomings of early mechanical drivelines1, which were prone to reliability issues. Today, the various original equipment manufacturers (OEMs) either find that the diesel-electric option offers many more benefits than the conventional mechanical option, or else they maintain that straight mechanical options remain the best driveline choice.

When considering which option to adopt for an addition to one’s fleet, customers should consider an investigation into historical performance monitoring to determine which alternative in the drive systems will bring them the best value.
When fuel efficiency, hauling productivity and operating costs are high on the priority list, mine operators, for example, are often drawn to trucks with electrically-driven wheels powered by diesel generators, instead of mechanical power train mechanisms with gearboxes and driveshafts.
Size class often enters into the equation here when making a choice, together with the selection of AC vs DC drive technology. DC technology has improved favourably in recent years, so customers sometimes wish to stick to what they know in terms of maintenance.
Transporting loose materials to a construction or mining site can be time-consuming and difficult if you don't have the right equipment. An underground dump truck is arguably one of the most important devices for transporting these items. Here are some of the benefits of buying an underground dump truck.
Here are the main points of the article:
What are the features of the underground dump truck?
What are the advantages of the underground dump truck?
What is special about the body and design of the underground dump truck?
The underground dump truck includes several key features that reduce maintenance time and cost, including:
Onboard diagnostics to help troubleshoot problems

Ground maintenance design to avoid climbing
Centralized lubrication system
Simple mechanical design with minimal electronic or computer systems
The frame will not twist: On a rigid frame dump truck, a heavy load over rough terrain can cause the frame to twist and the truck to become unusable. Underground dump truck operates differently because their tow-trailer combination allows the body and the towing unit to bend separately without risking damage to the frame.
More maneuverability: Underground dump trucks have a tighter turning radius than rigid frame dump trucks, which means they are easier to operate around mining and construction sites. Their large tires, wide frame and low center of gravity make these trucks ideal for off-road terrain. Underground dump trucks are easier to drive over muddy, rocky and uneven terrain, making them ideal for mining. These dump trucks are also perfect for construction sites with uneven ground because they can move easily and drivers don't have to worry about turning on the site.
Higher productivity: Underground dump trucks have much larger cabs, and some models are equipped with heated seats, air conditioning, user-friendly control systems and the ability to actively control ride suspension to reduce cab vibration. The combination of these factors will certainly increase workers' productivity because they will feel comfortable and safe during their working hours.
Most underground dump trucks used for small buildings and demolition projects have a design similar to a flat-bed truck, with two shafts and no drive behind the cab. Larger dump trucks may have more shafts for support, a joint at the back of the cab for increased maneuvers, and different tipping motions.
For the most part, a standard underground dump truck operates in a manner similar to many other vehicles. They usually have two axles, front steering and an internal combustion engine. A powered take-off system, or PTO, allows the bed to draw power from the vehicle's engine to operate the lift mechanism. The retractable hydraulic arm keeps the lifting mechanism compact while being able to tilt the tipping bed to extreme angles.
Underground dump trucks are ideal for construction sites with uneven terrain and conditions resulting in muddy roads. The frame will not distort, as it will with the rigid truck, you will be able to move the load at a faster speed. Because the frame can move rather than remain rigid, you will find that the mobility of underground dump trucks is much better, especially if you have to move other people and vehicles around a construction or mining site.
