Abstract

PURPOSE:To raise the safety, by detecting the contact of a contact member perpendicular to the longitudinal direction of rails through a detector to raise an alarm and de-energize a running motor. CONSTITUTION:When the contact member 24 comes into contact with an antenna 11a or 11b, a relay R2 is energized and its contact R21 is closed. Thereby, a relay R4 is energized, contacts R41, R43 are closed and a direction indicator lamp PL1 is lighted on. At the same time, a bell BL starts ringing to warn the operator. Relays R5, R6 are energized by an AC power source AC1 through the closing of the contact R43, thereby closing the contacts R51, R61 of the relays R5, R6. As a result, the running motor 4 is de-energized and the ground moving crane 1 stops running. Therefore, the contact member 24 is protected from being damaged, and the safety is raised.
