EXTENSION APPARATUS

PURPOSE:To prevent a holding rope and a traction rope from coming into mixed contact by equipping an intermediate holder with a second holding part for the holding rope below a first holding part for the traction rope and by providing an apparatus with a traveling part vertical to a connection for the traction rope and arranged in series for connecting the traction rope. CONSTITUTION:A first holding part 11 for holding a traction rope J and a second holding part 12 for holding a holding rope S are separately arranged within a minimum range enabling an apparatus 3 to pass through. For the purpose of forming the first holding part 11, lower and upper support rollers 14 and 15 and a side control roller 16 are mounted to a bracket frame 17 and the formed first holding part 11 is mounted to a steel tower for mounting an intermediate holder 2. The second holding part 12 is provided at a support arm 18 by a longitudinal frame part 10V to retain the holding rope S by a holding clamp 19. Thus, it is possible to prevent the holding rope S and the traction rope J from coming into mixed contact.
