Abstract
An industrial truck (1) has a drive section (2) and a load section (4) movable relative to the drive section (2). The load section (4) has at least one wheelarm (5) with at least one load roller (6). A linkage (10) is connected with the load roller (6). A lever system (11) activates the linkage (10). The lever system (11) comprises a first lever (15) swivelably mounted at a first bearing point (16) on the drive section (2) and swivelably mounted at a second bearing point (17) on the load section (4). A second lever (20) swivelably mounted at a bearing point (21) on the load section (4) and coupled at a coupling point (22) with the linkage (10). An intermediate lever (25) is connected at a coupling point (26) with the first lever (15) and at an additional coupling point (27) with the second lever (20).
Claims15
An industrial truck, comprising:
- a drive section;
- a load section movable relative to the drive section wherein the load section comprises at least one wheelarm and wherein the wheelarm includes at least one load roller;
- a linkage in an operative connection with the load roller to lift the wheelarm;
- and
- a lever system operatively connected to the linkage,
- wherein the lever system comprises a first lever swivelably mounted at a first bearing point on the drive section and swivelably mounted at a second bearing point on the load section, a second lever swivelably mounted at a bearing point on the load section and coupled at a coupling point with the linkage, and an intermediate lever connected with a coupling point of the first lever, separate from the first bearing point and the second bearing point, and an additional coupling point of the second lever.
A system, comprising:
- an industrial truck, comprising:
- a drive section;
- a load section movable relative to the drive section, wherein the load section comprises at least one wheelarm and wherein the wheelarm includes at least one load roller;
- a linkage in an operative connection with the load roller to lift the wheelarm;
- and
- a lever system operatively connected to the linkage,
- wherein the lever system comprises a first lever swivelably mounted at a first bearing point on the drive section and swivelably mounted at a second bearing point on the load section, a second lever swivelably mounted at a bearing point on the load section and coupled at a coupling point with the linkage, and an intermediate lever connected with a coupling point of the first lever, separate from the first bearing point and the second bearing point, and an additional coupling point of the second lever, wherein the industrial truck has a maximum wheelarm height in a fully lowered position of the load section of 50 mm;
- and
