TRACTION TYPE IN-DUCT MOVER, AND IN-DUCT MOVER

摘要

PURPOSE:To provide an in-duct mover which has materialized the traveling of an induct mover at a relatively specified speed and with a simple contrivance, regardless of the condition of a duct being the object of movement. CONSTITUTION:A traction type in-duct mover of such constitution that an in-duct mover moves inside a duct, while rolling a fraction rope, being equipped with said traction rope between the in-duct mover arranged inside the duct and the fraction rope fixing part arranged outside the duct, is equipped with a braking mechanism 11 which gives braking to the movement of the in-duct mover while stretching out from the in-duct mover to abut on the in-duct wall 200. And, this mover is equipped with a posture detector 12, which detects the inclination of the direction of movement from the horizontal direction, and a braking mechanism stretch controller 13 which stretches out the braking mechanism 11 in case that the posture detector 13 detects the direction of movement inclines downward in vertical direction from the horizontal direction.
