Dear friends in the construction #machinery industry, today let's talk about something exciting - when excavators leave the comfortableground working environment 

and go to work in the two "hellish difficulty" scenarios of the deep sea and space, what interesting stories happen?

Deep Sea Chapter: An Excavator Working in a pressure cooker

Imagine that your #excavator is suddenly thrown into the Mariana Trench (the place deeper than Mount Everest).  The water pressure here can easily flatten a tank.  

The temperature is close to freezing point and the seawater is particularly "salty" - extremely corrosive.  This is the daily routine that deep-sea mining has to face.

At this point, the problem arises: The hydraulic system of an ordinary excavator simply can't hold up here.  HS Hydraulic Equipment Co., Ltd.  The engineers have specially

developed the "Deep Sea Special Edition" hydraulic system for this purpose:

The shell made of titanium alloy is 30% lighter than traditional steel but has twice the strength

Special sealing technology is equivalent to putting on a "diving suit" for hydraulic components.

The intelligent control system enables the robotic arm to operate precisely even in an environment with zero visibility

Space Edition: What's it like to operate an excavator on the Moon?

If the deep sea is the "pressure cooker mode", then space is the "extreme difficulty PLUS version".  The temperature difference between day and night on the surface of the moon exceeds 200℃.  One can die of heat during the day and freeze to death at night, and there is also cosmic radiation everywhere.  What's more troublesome

 is that the gravity here is only one sixth of that on Earth.  When a traditional excavator throws a shovel down, it might float up first.

NASA's latest lunar excavator, RASSOR, looks like a "mechanical scorpion" and is specifically designed to deal with this special environment.  Komatsu 

of Japan is even more remarkable.  It has directly launched "digital twins", first simulating lunar operations on Earth using VR.
