"I am not a tool man!" - The roar from the CAT 312C hydraulic main pump
Hello everyone, I am CAT 312C hydraulic main pump.
A "heart-level worker" on the construction site, a hydraulic pressure king who never dares to catch a cold or be lazy.
You can call me "Little C Pump" or "Construction Site Pressure King". I don't mind, because - I can really "pressure" too much.
🛠 312C is working hard outside, but I am working in tears behind the scenes
Every morning before six o'clock, the driver presses the start button, and I am just about to take a deep breath, and a stream of hydraulic oil has already rushed in:
"Quick, quick, quick! Raise the arm, turn, rotate, and shovel! Follow the process! Don't let the chain down!"
Huh? Brother, I am a hydraulic pump, not a juicer!
😤You only see it loading soil, but you don't see me squeezing!
I am responsible for pressing the oil pressure into power, pressing the power into action, and pressing the action into efficiency!
Others work with work in their hands, and I work with the whole machine breathing on me.
In a word: whether 312C will move depends on whether I am in a good mood today.
(Of course, I have never been in a bad mood, after all, I have "full pressure resistance")
🤯I heard that someone used a "secondary factory pump" to replace me? I directly pumped the foundation down!
Once, Xiao Wang at the construction site was greedy and used a fake hydraulic pump from a subsidiary factory.
As a result, within three days, the sound was louder than that of a tractor, and the excavator arm trembled. The driver thought he had Parkinson's disease.
Later, it was me, the original CAT hydraulic main pump, who returned in a low-key manner and restored the "cat-like silky" of 312C.
🧊 How calm am I? Even summer is jealous of me
40-degree high temperature? Sandstorm? Heavy rain?
I said calmly: "Come on, whoever explodes first is a puppy."
My cooling system, oil circuit design, and sealing structure are all the "pressure-resistant ceiling" of the construction site.
🧡 With me, 312C is the "small tank in the construction industry"
I can withstand pressure, endure operation, and have stable output. I never go on strike, don't give up, and don't make a fuss.
Even if you work for 12 hours in a row, I will work silently to the end.
Don't look at me as silent, actually my slogan is:
"As long as the machine is there, I am there; if the machine is paralyzed, it must not be my fault!"
📦 So please, give your 312C a good heart!
You are not replacing a part, but the main power source that makes it return to its peak!
