ABSTRACT:
A hydraulic pipe mechanism for an industrial vehicle includes a pulley shaft, a plurality of hydraulic hoses and a pulley set. The pulley set is provided on the pulley shaft and has at least first and second hose pulleys that are rotatably supported on the pulley shaft. The first and second hose pulleys are respectively located on sides of the pulley set and each has a guide groove for hooking the hydraulic hose therein. Each of the first and second hose pulleys has a pair of outer and inner flanges that form side walls of the guide groove respectively. Each outer flange is located on the side of the pulley set, and each inner flange is located inside the outer flange in the pulley set. Each outer flange has a first radius, and each inner flange has a second radius. The first radius is larger than the second radius.
