Abstract

L'invention concerne une tour d'escalade de bloc et une unité d'escalade de bloc qui sont faciles à manipuler, par exemple, faciles à transporter et à installer et sur lesquelles le motif de disposition des prises d'escalade peut être modifié librement. La tour d'escalade de bloc (1) comprend une pluralité d'unités d'escalade de bloc sensiblement cylindriques (2) qui sont empilées verticalement avec leurs axes centraux alignés les uns avec les autres. Une pluralité de prises d'escalade (3) qui servent de prises lors de l'escalade sont fixées à la surface circonférentielle externe (1a) de celles-ci. Un corps de corde de type ceinture étroite (4), appelé une corde lâche, est également fixé à celles-ci par le biais d'un boulon à œillet (5).
