This is a method for constructing a vertical shaft using a circular casing tube without the use of sheet pile supports or liner plates, utilizing a revocable shaft machine. 【Features】 ○ The equipment is compact, requiring a small footprint. Additionally, with a body weight of 3.4 tons, it can be transported by a 4-ton truck. ○ Even in urban construction, it is less affected by nearby structures and obstacles compared to conventional methods, allowing for efficient work progress through the use of cover plates and other materials. ● For other functions and details, please contact us.

The method of constructing a shaft easily and at low cost using the Rev II shaft machine, which is a further miniaturized version of the Rev shaft machine. 【Features】 ○ The Rev shaft machine has been further miniaturized, reducing its width to 1.7m and weight to 1.46t, and achieving a split-type design (upper part: 0.74t, lower part: 0.72t), allowing for the transportation and installation/removal of the machine using a 2t crane truck (lifting capacity of 2t). ○ With easier installation and removal, casing recovery has become possible. This allows the casing costs, which accounted for a large portion of construction expenses, to be recorded as a loss, enabling further cost reductions. ● For other functions and details, please contact us.
