Abstract

The invention discloses a multifunctional truck special for disassembling and assembling expressway signboards. The traditional lagged equipment and process for signing and assembling cannot meet the demands of expressway construction, so that the transformation from low-efficiency mechanical equipment with simple steel tube brackets, staircase and no safety guarantee into the mode of specialization, high mechanical safety and high efficiency is necessary. The multifunctional truck comprises a truck (1), wherein the middle of a carriage of the truck is fixedly connected with a turnplate (2) which is connected with a group of parallel tracks (3); the tracks are connected with a lifter which is connected with an adjustable work tabletop (4); and the other ends of the tracks are connected with cross arms (5) which are connected with Y-shaped supporting legs through safety positioning pins (6). The multifunctional truck is used for aloftwork such as the disassembly, the assembly and the like of road signs and billboards of expressways.

Description

Technical field: [0001] The invention relates to a hydraulic lifting vehicle which enlarges the lifting space and facilitates movement. Background technique: [0002] With the rapid development of highway construction, the amount of domestic and provincial projects has increased year by year. The backward equipment and technology used for sign + installation can no longer meet the needs of highway construction. Simple steel pipe supports, artificial escalators, and no safety guarantees are required. The low-efficiency mechanical equipment is transformed into a professional, mechanized, high-safety, high-efficiency mode. And expressway signs have their particularity: most of the foundations of expressway signs are below the road shoulder, and there is a certain horizontal distance from the road shoulder, the distance is even 5 or 6 meters, and the vertical distance between the foundation and the road shoulder is also high or short. Not fixed and other factors, installation, ...
