CURRENT COLLECTOR ARRANGEMENT FOR INSULATED TROLLEY

摘要

PROBLEM TO BE SOLVED: To provide a current collector arrangement for an insulated trolley with a fitting bracket harder to deform for stable use for an extended period. SOLUTION: The fitting bracket of the current collector arrangement for an insulated trolley comprises an arm to which a shoe head comprising a current collector at its tip is attached and which presses the shoe head against a trolley line from below, and a fitting bracket which supports the arm through a vertical axis and the horizontal axis for horizontal rotation and vertical rotation and secures it to a mobile transportation equipment. It comprises a recess so formed as to wrap the horizontal axis for free rotation at its central part, and a pair of brackets which is provided to both ends of the recess and comprises a hinge where a screw-fitting part is formed. The bracket wraps only the upper part of the horizontal axis, and the lower exposed part of the horizontal axis is provided with a vertical axis that supports the arm for vertical rotation. The bracket is secured to the mobile transportation equipment through the screw-fitting part provided to the hinge. COPYRIGHT: (C)2004,JPO
