Device according to any preceding claim, wherein the operator's cabin (9) includes front corner posts (42) which conceal a part (SO) of the operator's view obliquely forward in the driving direction (F) when the operator is sitting on the operator's seat (10), characterized in that the frame beams (16, 17, 19, 20) of the fixed and movable frames (12, 13) are located relative to the corner posts (42) such that they at least partly are situated within the part (SO) of the operator's view concealed by said corner posts (42).

Device according to any preceding claim, wherein the lifting carriage (14) comprises vertically mounted frame beams (46), characterized in that the vertically mounted frame beams (46) of the lifting carriage (14) are inclined relative to the driving direction (F) such that they are situated substantially in parallel with a line of aim (SL) from the operator when the operator is sitting on the operator's seat (10), in a direction obliquely forward in the driving direction (F).

Device according to any preceding claim, characterized in that front members (44) of the operator's cabin (9), seen in the driving direction (F) of the counterweight lift truck (1), are located between the frames (12, 13).

Device according to any preceding claim, characterized in that front members (44) of the operator's cabin (9), seen in the driving direction (F) of the counterweight lift truck (1), extend beyond the frames (12, 13).

Device according to any preceding claim, characterized in that the vertical frame beams (16, 17 and 19, 20) of the fixed and movable frames (12, 13) are, seen in the driving direction (F), located immediately behind a vertical plane (D) which is transverse relative to the driving direction (F) and which is found just behind the wheel periphery (3a) of the front wheels (3, 4).

Device according to any preceding claim, wherein the operator's cabin (9) includes at least one side door (43), characterized in that, seen in the driving direction (F), the vertically directed frame beams (16, 17 and 19, 20) of the fixed and movable frames (12, 13) are located just in front of the side door (43) such that the operator can pass into and out of the operator's cabin (9).

Device according to any preceding claim, characterized in that the upper transverse frame beams (18, 21) of the fixed and movable frames (12, 13) are located above front members (44) of the operator's cabin (9) such that they protect the cabin (9) against goods falling down.

Device according to any preceding claim, characterized in

• that at least one support device (26) is provided between each vertically mounted frame beam (16 and 17) of the fixed frame (12) and a vertically mounted frame beam (19 and 20) of the movable frame (13) within said first frame beam (16 and 17), and
• that at least one support device (27) is provided between the lifting carriage (14) and each vertically mounted frame beam (19 and 20) of the movable frame (13).

Device according to any preceding claim, characterized in that four support devices (26, 27) are provided on one level and four other support devices (26, 27) on another level.

Device according to any preceding claim, characterized in that each support device (26, 27) has at least one support roll (28 and/or 29) which is rotatably mounted on an axis (30) which is located in parallel with the driving direction (F), that the support roll (28 and/or 29) in the support device (26) of the movable frame (13) engages and can roll on support surfaces (33, 34) on the vertical frame beam (16 and/or 17) of the fixed frame (12) and that the support roll (28 and/or 29) in the support device (27) of the lifting carriage (14) engages and can roll on support surfaces (33, 34) on the vertical frame beam (19 and/or 20) of the movable frame (13).

Device according to any preceding claim, characterized in that the substantially vertically mounted frame beams (16, 17 and 19, 20 respectively) of the fixed and the movable frame (12 and 13 respectively) have a substantially U-shaped cross section, whereby webs or web members (47) of the frame beams (16, 17, 19, 20) are provided in parallel with the driving direction (F) and shanks (48, 49) extending from said web members (47) define a right angle with the driving direction (F) and are directed inwards towards central parts of the counterweight lift truck (1).

Device according to any preceding claim, characterized in

• that the lifting unit comprises a lifting cylinder (22) which is provided on one of the vertically mounted frame beams (16) of the fixed frame (12), and
