Structure for mounting cover of controller in battery fork lift

In a battery-driven fork lift truck including at the rear end thereof a counterweight formed therein with a controller room having an opening in a substantially vertical rear end surface of the counterweight, and a comparatively thick and heavy cover which is mounted on the counterweight to close the opening, a structure for mounting the cover comprising in combination:

• upper and lower body-side hinge members secured integrally to the counterweight along a vertical edge of the opening, said upper and lower body-side hinge members being steel bars with bent legs of the two hinge members extending toward each other;
• and
• upper and lower cover-side hinge members secured integrally to the cover along a vertical edge thereof so as to be engaged with and disengaged from the upper and lower body-side hinge members, respectively;
• said upper cover-side hinge member being a bent steel sheet with a U-shaped cross section having a pair of horizontal legs extending in one direction, and first means extending across free ends of the legs to prevent horizontal displacement of the upper body-side hinge member when the upper body-side hinge member is in engagement with the upper cover-side hinge member;
• said lower cover-side hinge member being a bent steel sheet with a U-shaped cross section having a pair of horizontal legs extending in opposite directions of the legs of said upper cover-side hinge member, second means extending across free ends of the legs to prevent horizontal displacement of the lower body-side hinge member when the lower body-side hinge member is in engagement with the lower cover-side hinge member, and third means extending across top edges of the legs to abut with the top end of the lower cover-side hinge member thus preventing the cover from displacing vertically downwards with respect to the counterweight.
