LIFTING CARRYING-OUT METHOD AND LIFTING TRUCK OF UNDERGROUND BURIED FACILITY

摘要

PROBLEM TO BE SOLVED: To shorten the lifting stroke in separation of a buried facility body from a container on the ground and shorten the total height of a lifting truck by winding a suspending belt on a suspending belt winding shaft provided between lift arms to shorten it. ;SOLUTION: A suspending belt winding shaft 23 having an outer diameter of about 50 mm is provided between lift arms 15 of a lifting truck. When a buried manhole pump control board A is lifted up, a suspending belt V is hooked on the suspending bracket of the sheet pile part of a container C, an operation handle is rotated to retreat the lifting truck, and the control board A is set on the ground. One side of the suspending belt V is released and re-hooked after the excessive length part thereof is wound on the winding shaft 23 and shortened, and the container C released in the connection with the body B of the control board A is lifted up and separated. The necessary stroke S of the lift arm 15 is shortened by half of the shortening portion of the suspending belt V, compared with the stroke S' by a conventional method, and the total height H of the lifting truck can be made smaller by S-S' than the conventional total height H', so that the separating work can be stably performed.;COPYRIGHT: (C)2000,JPO
