Abstract
A vehicle cab with a roof hatch (12) which comprises front and rear hatch sections (14) and (16), the rear section (14) being over an escape hatchway (26) and the front section (16) being over an equipment access hatchway (28) of a roof compartment. The front hatch section (16) is mounted on a front roof section (10a) along its forward edge by hinges (18), and releasably latched to a middle roof section (10c) along its rearward edge by secondary latches (22). The rear hatch section (14) is mounted on the rearward edge of the front hatch section (16) by hinges (20), and releasably latched to the rear roof section (10b) by a primary latch (40). The primary catch (40) may be released and the rear hatch section (14) may be partially opened and retained with rear stays (64) to provide ventilation. The rear stays (64) may then be automatically released when the rear hatch section (14) is pushed past the retention point to fully open the escape hatchway (26). The secondary catches (22) may then be released and the front hatch section (16) opened and supported by front stays (78), to provide access to the roof compartment through the equipment access hatchway (28).
