Abstract: PURPOSE: A braking device for traveling of a cargo-handling machine is provided to prevent an accident and damage while improving efficiency through preventing the machine from being pushed in operation caused by strong wind. CONSTITUTION: After completing operation of a cargo-handling machine, a rail clamp is combined to lower a spring base. Thus, a wire(69) is drooped. A braking gear(60) is lowered by a roller rotated along a bracket. Thus, the braking gear is engaged between a traveling gear(6) and the bracket. Therefore, the traveling gear is stopped. In operation of the cargo-handling machine, the rail clamp is released. Thus, the spring base is elevated for releasing the braking gear from the traveling gear. In case of strong wind in combined state of the braking gear, the rail clamp is released. Thus, one braking gear is released while not releasing the other braking gear. Herein, a tension spring is extended for elevating the braking gear by the traveling gear. Therefore, the braking gear is released by the tension spring. Moreover, a shock absorbing spring(63) is arranged for absorbing shock caused by sudden release of the braking gear.

Abstract: PURPOSE: A method for testing a digital exchange trunk line is provided to enable all trunk lines having R2 and ISUP signaling types, and make a remote loop-back for each trunk in a trunk interface board of a response station. CONSTITUTION: A test station transfers a test instruction to a trunk test block in the test station. The trunk test block opens a communication path, and checks a signaling type of a test target trunk line. The trunk test block sends a special number for test to a signal process block. The signal process block occupies the trunk line in order to transmits the special number to the response station. A number translation block in the response station translates the special number, and sends a remote loop-back instruction to a control board if the translated number is recognized as the special number for the test. The control board sends the remote loop-back instruction to the trunk interface board, which establishes a communication path between the test station and the response station. A trunk test device in the test station sends a test signal to the response station. The trunk interface board checks characteristics of retransmitted inputted signal, and thereby determines whether an error has occurred.
