<p><P>PROBLEM TO BE SOLVED: To provide a trackless type gondola apparatus which has a simple structure and enables operability to be nearly the same as that of a track type gondola apparatus though it is the trackless type. <P>SOLUTION: The trackless type gondola apparatus suspends and supports a raised/lowered working machine through the arm of a truck which has a drive traveling mechanism and a drive steering mechanism and travels tracklessly on a structure. The trackless type gondola apparatus is provided with a guide member 61 provided on the travelling path of the truck 20, a sensor member 62 which is set in the truck and detects the traveling position of the truck by information from the guide member, and a control device 60 which calculates a displacement amount from the traveling path based on input information from the sensor member and outputs a control signal for correcting the displacement amount to the drive travelling mechanism and the drive steering mechanism. Accordingly, the truck 20 is controllably traveled along the guide member and is made to travel like a track type and thus moves efficiently for a short time by controlling the drive travelling mechanism and the drive steering mechanism with the control device in such a way as to correct the displacement amount. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
