Problems solved by technology

Because multiple guide rollers guide the hose while making point contact with the hose, the hose tends to be guided in such a way that it crosses the guide rollers so that the hose cannot be guided smoothly
In addition, since the diameter of the guide roller is small, the guide roller rotates at a high speed during the guiding of the hose, so that the hose tends to easily slip relative to the guide roller and the surface of the hose may be damaged.
Replacing a damaged hose with a new one is laborious and time consuming as the hydraulic fluid must be drained from the hose before it can be removed for replacement
In addition, hydraulic fluid or hydraulic oil may accidentally leak from the hose during the above-mentioned replacement operation, thereby damaging the working environment

Abstract

A lifting device for an industrial vehicle, comprising: a hydraulic cylinder disposed approximately vertically between uprights and having a piston rod; a pulley disposed on the lateral side of the upper end of the piston rod; chain connection around, and, by means of telescoping of the piston rod, the lifting frame can be moved up and down by the chain; a hose, provided for supplying hydraulic fluid to accessories mounted on the lifting frame; and, a guide mechanism, provided on the piston rod on the top end of the hose for guiding the hose. The guide mechanism includes: a plurality of rollers; a support member rotatably supporting the plurality of rollers; and an endless belt fitted around the plurality of rollers to form an arc-shaped guide surface for supporting the hose. As the hose moves, the endless belt travels around the plurality of rollers.

Description

technical field [0001] The present invention relates generally to a lifting device and, more particularly, to a lifting device for an industrial vehicle on which a guide mechanism for guiding a hose is mounted. Background technique [0002] In a forklift as an industrial vehicle, its lifting frame can be fitted with various attachments designed to perform different operations. In this case, hydraulic lines are required for supplying hydraulic fluid to drive the attachments. [0003] A conventional lifting device for industrial vehicles is disclosed in Japanese Patent Application Laid-Open No. 2002-20087. The lifting device of the industrial vehicle (hereinafter simply referred to as "the lifting device") is a lifting device for a three-section post forklift. The lifting device has a hydraulic cylinder located between the separated uprights. At the top end of the piston rod of the hydraulic cylinder, a pulley is supported, which has two grooves for guiding the chain and th...
