An industrial truck driver protection roof has a frame with front-end and rear-end vertical load-bearing struts (T1-T4) that are located at a distance from each other in a transverse direction of the vehicle, and horizontal roof trusses (D1-D13) that are located in the roof area. The frame has two prefabricated assemblies (I, II) that are configured so that they can be connected to each other. Each assembly (I and II) includes two load-bearing struts (T1, T2 and T3, T4) and at least one roof truss (D1, D2, D3 and D4, D5, D6, respectively) that connects the load-bearing struts (T1, T2 and T3, T4, respectively) to each other.
