What NOT to do with Heavy equipment. Warning signs & mistakes in a 60 ton rock truck #1

What happens here

Eric explains the key differences between articulated haulers and rigid mining trucks. He emphasizes the 6-wheel drive and the unique 'swivel' articulation joint on the Volvo A60H, which allows the truck to traverse extremely rough and uneven terrain where rigid trucks would struggle. He also highlights a critical safety feature: the design allows the truck bed to tip over in a severe accident, but the cab remains stable, ensuring operator safety. The exhaust system is designed to separate upon impact, facilitating easier recovery.

Goal: Understand the functional advantages and safety mechanisms of articulated haulers.

Tools and materials

  • Articulated Joint — Allows for independent movement of truck sections
  • Exhaust System — Designed to separate during a rollover for easier recovery
  • Hydraulic Hoses — Connect various systems across the articulated joint
  • Volvo A60H Rock Truck Volvo — Demonstrating articulated design and roll-over features

Okay. So, let me ask you something. What's the difference between an off-road hauler, cuz that's what you consider this, right? Yeah. And a mining truck. Okay. The difference is you got a six-wheel drive platform that's driving the truck. So, six wheel drive versus two wheel drive. So, a rigid hall truck is a two-w wheelel drive truck. Just the axles in the back are actually running the truck. So, it's great on flat ground. Well, you know, really good hall road. When you get a nasty dirt, less maintained hall roads, really steep grades, six-wheel drive is the way, the only way to go. Okay. So, if I heard you right, the difference between this and a mining truck is that this is actually built more for off-road applications where a mining truck is typically built to be put onto hall roads, which are pretty much what we're on right now. between different pitches and grades, but we're not talking about rough terrain or uneven terrain. This thing is like a giant four-wheel drive pick off-road pickup truck versus a four-wheel drive city truck that probably hauls paper around. Whereas a rigid truck drives in the front, but your front tires actually steer. The whole back of this truck is actually steering the truck. So, you got a swivel right here. swivels this way and then you turn this way. So you can go over those different types of terrains that a rigid truck couldn't go over. Okay. So this actually steers more like a payloader then, right? So this is Yeah, exactly. So this is a big swivel right here. There's tapered roller bearings in here that are greased for life. There's no maintenance here and it allows that truck to actually turn like this back and forth over the terrain. So you're going like this. So if you were in a rigid truck, it'd be going like this. Okay. It would you wouldn't get the good ride. Okay. Now, that's also a safety feature. Absolutely. The safety feature is is you can tip this part of the truck over while the cab stays stationary. Yes. If you if you're not careful what you're doing, how you're loading and unloading these trucks, Mhm. it can turn over. Yes. Absolutely. So, if it turns over, what are we damaging? Just the side of the truck. So, it basically lays over on side. You bring an excavator back over, pull it over. What about the exhaust system? That has springs in there and it actually pull away from each other. So, do you have to put a new You'll have to just put it back together. You don't need a new exhaust system. No,…
