Machine 27R:

While initially appearing designed for column erection, this machine's feasibility in that role is uncertain. It requires the shaft to be pre -set at an angle, potentially facilitated by another device. Additionally, its ability to erect the column is limited to a few degrees, casting doubt on its use for column logistics. Upon profound examination, this machine might serve better in operating cannons. The angles it allows align well with a 45 -degree firing angle, making it suitable for adjusting to different targets.
