Abstract
A slide rail assembly (18) and slide plate (20) are used, for example, to position an implement (14) of a work vehicle (10), such as a bulldozer (14), at various angles. The bulldozer connected slide plate (20) moves along a vehicle connected rail (22) of the rail assembly (18) to a desired position of the bulldozer (14). A pin (50) is positioned through openings (48,52) in the rail (22) and slide plate (20) to maintain the position. The pin (50) or rail (22) can sometimes fail owing to working loads exerted on the bulldozer (14). Support members (54) each having pin receiving openings (56) in register with respective rail openings (48) are connected to the rail assembly (18) to increase bearing support area of the pin (50) and to strengthen the rail assembly (18). The support members (54) also each have openings (58) aligned with openings (44,46) in the rail assembly (18) for relief of material packed into the rail (22) and into the pin receiving openings (48,56).
