Experimental workshop.
The environment here is far inferior to that in the assembly workshop.
Because every assembled excavator must undergo various overload operations.
Used to check various indicators and performance of the equipment.
Especially in hydraulic systems, the ultimate pressure of each oil pipe is different, and adjustments must be made on the valve assembly.
In addition, the excavator also needs to undergo a hill-climbing test.
An 18-degree slope occupies a significant portion of the space.
The bottom is made of piled stones, and the top is made of rammed loess.
Even so, the excavator still brought down a lot of soil when it climbed up.
In addition to the hydraulic oil leak, despite the constant cleaning efforts of the staff, oil stains still remain on the ground.
Wang Hui said in a low voice, "The test workshop is a bit dirty, please don't mind. Of course, this climbing test platform was originally a planning mistake, and we plan to dismantle it soon."
Old Zhang asked, "Why? This experiment is really good. I've never seen anything like it at other manufacturers. Why dismantle it when it's perfectly fine?"
"It's a misunderstanding," Wang Hui explained. "Actually, we wanted to replace it with an iron platform to avoid the workshop being covered in dirt."
Old Zhang said, "Oh, I see. This hill-climbing test is great. After all, excavators don't work on flat surfaces; sometimes they have to go up slopes. With the hill-climbing data, we can decide whether to clear the road or go straight up, saving time."
Wang Hui nodded: "These data are all consistent with ours, so there won't be any situation where the climbing ability of each excavator is different."
Afterwards, Wang Hui led everyone to the excavator manufacturing site.
Trailers are constantly coming and going here, hauling excavators to all parts of the country.
Old Zhang smiled and said, "Looks like the shipment volume is pretty good."
Wang Hui modestly said, "To be honest, if I say that sales are booming, you might think I'm bragging, but we are truly favored by customers."
"Look at this cab," Wang Hui said, opening the door of an excavator. "Although there are many dashboards, they are all instruments that monitor the performance of various components of the excavator."
"For example, this one."
Wang Hui pointed to one of the electronic dials and enthusiastically introduced it:
"S, H, and L are used to represent the working modes of the excavator."
Upon hearing this, Lao Zhang, who had been in contact with construction equipment for many years, was dumbfounded.
What?
What are they?!
I've never seen or heard of this before!
This is really something new!
Everyone was curious and eager to see what was going on.
Seeing that everyone's interest had been piqued, Wang Hui realized that sales was a really good job!
It feels like being a teacher, it's absolutely fantastic!
This caused his adrenaline to surge.
Old Zhang asked anxiously, "Quick, tell me what's going on? Can an excavator have three working modes? Isn't it just for working?"
Wang Hui smiled faintly: "That's all ancient history! Trains have increased their speed, so excavators can't lag behind."
Old Zhang burst into laughter: "You guys aren't just making a gimmick, are you? I've seen plenty of these things. You put up something useless and call it high-tech, just trying to fool people."
Wang Hui quickly explained, "Qimingxing is a company that gets things done. We only add equipment when needed, and we will never add any burden if it is not needed."
"Now I'll explain the working mode of the excavator."
"Based on our R&D personnel's observations of the equipment's operation, excavators have three working modes: heavy load, standard, and light load."
"S stands for Standard Mode. This is an abbreviation for a mode suitable for excavating hard ground in a short time."
"H represents heavy-duty mode. This mode prioritizes fuel consumption and is suitable for general operations such as loading."
"L stands for light load mode. This mode is suitable for slope cutting, leveling, or light load operations."
Old Zhang was very surprised.
In the past, there were no three modes; you just got on the truck and started working. There was no distinction between light and heavy loads.
But after hearing what Wang Hui said, it really did seem to make sense.
Loading requires a bucket to dig up the soil, which increases the weight.
Xiuping and other tasks are simple and require almost no effort to complete.
Therefore, it is clear that the fuel consumption is different for heavy loads and light loads.
Modern excavators don't have this problem at all; once the machine is started, all that's needed is fuel consumption.
Just like a car, flat roads save fuel, while going uphill consumes more fuel.
The excavators are currently operating at maximum fuel consumption, even when going uphill.
Now that I think about it, it seems like we wasted a lot of diesel fuel!
Not only was Lao Zhang surprised, but his entourage was also shocked.
This is the most interesting design!
Compared to installing an air conditioner, what good is that thing?
The driver may feel cooler, but we're still the ones paying for the fuel, aren't we?
Old Zhang whispered to the others, "This design is really good, what do you all think?"
"Indeed, you have to switch to different modes when doing different jobs."
"Yes, this is called making the most of resources. Look at the excavators we have now, it feels like using a cannon to kill a mosquito, it doesn't do anything for the smallest details."
"It's true that you don't know the harm without comparison. The more I look at this excavator, the smuger I feel."
"It's true, this excavator is great. It encourages the driver to do different jobs and switches between different modes, which can save a lot of diesel fuel."
The group chatted away for a while, each talking at their own pace.
Old Zhang asked again, "Explain the rest."
“Okay.” Wang Hui spoke fluently: “Automatic preheating, rotating flashing light, automatic idle stop, working device, and flow setting for crushing mode.”
"These are all monitored and switched via the screen."
