Abstract
A counterweighted fork-lift truck has a vehicle frame (1) with a frame segment (2) having a lateral frame opening (2b). A pivoting door (3) covers the frame opening (2a). The door (3) is connected to the vehicle frame (1) by a double hinge (5). Protection against buckling is provided such that when the door (3) is in the closed position, an intermediate door leaf (3a) located between the axes of rotation (A1, A2) can be blocked in position with respect to an adjacent main leaf (3b). The protection against buckling has a spring element (24) with which, in the closed position of the door (3), the intermediate leaf (3a) is biased toward the open position and is in engagement with a stop (25), which is fastened to the main leaf (3b). The intermediate leaf (3a) and the main leaf (3b) enclose an obtuse angle (S).
