Payloader Basics for beginners- how to run, operate & understand Heavy equipment part 1

What happens here

This segment continues the machine walkaround, focusing on the rear frame, which houses the engine and the bulk of the drive line. The operator's cab is strategically positioned towards the rear of the machine for optimal visibility. The video also details the counterweight system at the rear, explaining that the amount of counterweight (standard or additional bolt-on weights) can vary based on the density of the material being handled and the specific application, ensuring machine stability during operation. Daily checks of fluids (hydraulic, oil, coolant) and air filters are also mentioned as critical for machine maintenance.

Goal: Comprehend the function of the rear frame and the importance of proper counterweighting

What they say

but actually these wheels will track in the same line. So, when you turn, the back wheels will follow the front wheels. So, it's going to it's going to turn a little bit sharper than an automobile. Um, and also the steering characteristics are a little bit different. And we'll we'll show you that once you get in there. Is there anything on the other side of the uh the unit we should look at? Yeah. Yeah. Why don't we take a walk over there? Okay. So, on this side of the machine, we have our our batteries. Also, we'll have um most machines, just about all machines now have a filtration system for you in the cab. So, this filter system filters the air you're breathing cuz I mean, as you can imagine, these machines get get themselves into some really dirty, dusty environments along with our our air filter system for the engine as well. All machines are going to have basic checkpoints. You know, you have to check hydraulic fluid, you have to check your oil, your coolant, all that. And then finally, in the rear of the machine, we have our counterwe. Um, and depending on what we're doing, what type of application the machine's in, we may have more or less counterwe. Um, so like material handling, like rehandling of material, generally we want a lot of counterwe on the machine because we're lifting different densities of material. So, we want to have that this counterwe basically counters the weight that you're going to apply to the bucket to keep the machine stable while you're operating. Now, there's going to be two basic different kinds of payloaders basically built the same. One will be more for mining and harvesting materials in an application like we're at right here. And another one would that be for more off-road digging and excavating and and just general purpose? And so the counterweights would be different on those two machines. Like a a mining machine would have more and a and an off-road machine have less. Or am I wrong with that? It really depends. I mean, if you're I mean, with a general purpose machine, we we tend to like to to provide the counterwe as well, the extra counterweight, cuz we never know what the customer is going to do with it. The main counterweights on all our machines are they're at a set weight. And then we have what we call our rehandling or logging counterwe that you see that bolts on under the there. That's what that's what we'd add for additional counterwe um if the customer had a high density material or or they were using…
