  • Patent number: 6547041
    Abstract: The present invention relates to a device at counterweight lift trucks (1) for giving the operator a substantially free field of view in the driving direction (F). A lifting device (11) comprises a vertically movable frame (13) which is mounted on a fixed frame (12) and which includes a lifting carriage (14). The counterweight lift truck (1) comprises an operator's cabin (9) with a seat (10) for the operator. The frames (12, 13) are, seen in the driving direction (F), located behind a vertical plane (A) which is transverse relative to the driving direction (F) and in which front wheels (3, 4) of the counterweight lift truck (1) are situated. The frames (12, 13) lack transverse beams beneath upper transverse beams (18, 21).
