Abstract
PURPOSE: To make sure of a reliable emergency stop of an elevator step in a welding and grinding device for a crude oil tank or the like by providing a jaw guide expanding toward its end in an emergency stopper mechanism for the elevator step, and utilizing the subsequent effect of a wedge.
CONSTITUTION: A coupling support portion 92 in an elevator step is so arranged that is moved downward immediately by being pulled by a spring mechanism 93 when a hoist chain 33 is broken. This occurrence is detected by a contactless switch 94 for operating an emergency stopper mechanism 63. The emergency stopper mechanism 63 is disposed in a channel portion of a support 15B of a carrier body, and has braking jaws 77A, 77B which are adapted to be pressed on the both side walls of the support 15B so as to stop the vertical movement of a stopper frame 31B of the elevator step.
