摘要： PROBLEM TO BE SOLVED: To solely, easily and quickly allow a worker to identify a location at which a ground leakage occurs.
SOLUTION: A ground leakage probing apparatus is provided with: a ground leakage checking current carrying section for sequentially carrying a current to an output device connected to an output section of a PLC for controlling a sequence in a freshly-mixed concrete manufacturing plant, a motor connected to a power outputting section controlled by an output from the output section and an input device connected to an input section for 0.3 second so as to prevent their operations; a storage section for storing the device to which the current is carried when an input is detected at a ground leakage contact while the current is carried to the device; and a display section for identifying and displaying the devices stored in the storage section. The current is sequentially carried to all the devices in the plant for 0.3 second at the same voltage as a voltage during a normal operation. The device whose leakage current is detected by a ground leakage relay is identified as the ground leakage location when the current is carried.

摘要： PROBLEM TO BE SOLVED: To prevent a boom of a mobile concrete pump from interfering with a cab.
SOLUTION: The mobile concrete pump having the boom is constructed by mounting a revolving frame 4 on a deck on the rear of the cab 1, and arranging the multi-stage boom 5 for supporting concrete feeding pipes 12, on the revolving frame. Then a support base 23 consisting of a laterally extending bar 24 and side bars 26 protruding diagonally rearward from both edges of the bar and each having a progressively declining upper surface, is arranged on a roof 1a of the cab 1. Further tape switches 27a, 27b are arranged on the bar 24 and the side bars 26 via cushioning members 28. When the multi-stage boom 5 is controlled to carry out forward falling operation or rotating operation, if the boom abuts on the tape switches 27a, 27b, a control section immediately halts contractive motion of a lower-stage boom derricking hydraulic cylinder 7 and rotary motion of the revolving frame 4, and therefore boom operation of the multi-stage boom 5 is immediately halted at the time of abutting on the tape switches 27a, 27b, to thereby prevent the boom from interfering with the cab 1.
