Abstract

For higher durability and easier assembly, a locking apparatus holding and releasing an ascended position of a hoist table, is structured such that engagement arms are connected to upper end portions of link arms connected to hoist table side of a parallel link mechanism to freely oscillate frontward, engagement bodies are provided in front end portions of the engagement arms, annular guide grooves guiding the engagement bodies in longitudinal and vertical directions are provided in side portion frames of a fork frame, a stopper walls having step shaped rear portions are provided in upper portions of the grooves, and front portions of the grooves are provided with check valves allowing the engagement bodies to pass through forward and guiding the passed engagement bodies to upper portion side of the guide grooves.

Description

technical field [0001] The invention relates to a buckle device of a lifting trolley, which transports a receiving box containing parts, food and other small items in a lifting manner. Background technique [0002] The prior art includes the types shown in Figs. 8-10. In Figure 8~ Figure 10 Among them, the reference number 1 represents the lifting trolley, and the reference number 2 represents its support. This bracket 2 is formed by a pair of side frames 2a, 2a spaced apart left and right and a transverse frame 2b connected to the rear portion of the side frame (right part in FIG. Front wheels 3, 3 are attached to the front portions of the side frames 2a, 2a, and rear wheels (casters) 4, 4 and handles 6 are attached to both left and right end portions of the horizontal frame 2b. [0003] A fork-shaped elevating table 5 is fitted to the support 2 so as to be movable up and down from above. This elevating platform 5 is composed of side elevating platforms 5a, 5a covering ...
