Abstract

PURPOSE: To permit to prevent the breakage of driver's cab by providing means for detecting an approach of a boom to the top portion of driver's cab in a concrete pump vehicle equipped with a multi-stage refraction boom. CONSTITUTION: A limit switch SW11 is provided in an upper portion of a driver' s cab for detecting an approach of a base boom 6 or a first front portion boom 7. Also, a limit switch SW12 is provided below a slewing base 3 for checking whether the slewing position of the base boom 6 interferes with the driver's cab 1. in addition, a limit switch SW13 is provided above the pump equipment 2 for detecting the facing and contact of the first refraction cylinder 15. And the signals from the switches SW11, SW12, and SW13 are guided to a controller, and slewing, rising or lowering of the boom is stopped when a dangerous situation approaches.
