Tree transplanting tub for on site assembly - uses mechanically tensioned clamping straps secured to staves by nailing

摘要

The equipment allows the construction on site of a cylindrical or conical tub of wooden planks, for the transport of trees and shrubs when transplanting. Clamping straps (M) are placed under tension mechanically, and equipped for securing them to each of the staves (B). The space occupied by each group of holes is greater than that between adjacent groups. The latter space can be less than the mean width of a stave forming part of the tub.
