Abstract

An industrial truck extends along a longitudinal truck axis and comprises a drive section and a stand-on platform positioned on the drive section. The stand-on platform comprises a base element configured to pivot about a first pivot axis and a stand-on element mounted to the base element and configured to pivot about a second pivot axis. The first pivot axis is parallel to the second pivot axis and offset from the second pivot axis by an offset distance in a direction of a longitudinal truck axis, and the stand-on element is configured to extend above the base element to form a standing surface. A first suspension is configured to support the base element and a second suspension is configured to support the stand-on element. The first suspension is positioned at a distance from the second suspension in the direction of the longitudinal truck axis.

First claim

1 . An industrial truck extending along a longitudinal truck axis and comprising:
a drive section; and a stand-on platform positioned on the drive section, the stand-on platform comprising, a base element configured to pivot about a first pivot axis,
a stand-on element mounted to the base element and configured to pivot about a second pivot axis, wherein the first pivot axis is parallel to the second pivot axis and offset from the second pivot axis by an offset distance in a direction of the longitudinal truck axis, and wherein the stand-on element is configured to extend above the base element to form a standing surface,
a first suspension configured to support the base element, and
a second suspension configured to support the stand-on element, wherein the first suspension is positioned at a distance from the second suspension in the direction of the longitudinal truck axis.

2 . The industrial truck according to claim 1 , wherein the first pivot axis is positioned at a first end of the base element and the first suspension is positioned at a second end of the base element.

3 . The industrial truck according to claim 2 , wherein the first suspension is positioned between the base element and an underbody extending below the base element, and wherein the second end of the base element is located opposite the first end in the direction of the longitudinal truck axis.

4 . The industrial truck according to claim 1 , wherein the first suspension is positioned on a lever arm extending from the base element.

5 . The industrial truck of claim 4 , wherein the lever arm extends in the direction of the longitudinal truck axis.

6 . The industrial truck according to claim 1 , wherein at least one of:
(i) a spring force exerted by the first suspension is greatest in a region of the second pivot axis; and (ii) a spring force exerted by the second suspension is greatest in a region of the first pivot axis.

7 . The industrial truck according to claim 1 , wherein at least one of:
(i) the first suspension is positioned in a region of the second pivot axis; and (ii) the second suspension is positioned in a region of the first pivot axis.

8 . The industrial truck according to claim 1 , wherein the first pivot axis extends along a first end of the base element and the second pivot axis extends along a second end of the base element, and wherein the first end is coupled to the industrial truck and the second end is opposite the first end.

9 . The industrial truck according to claim 1 , wherein the stand-on element is supported by the second suspension during a pivot movement about the second pivot axis.

10 . The industrial truck according to claim 1 , wherein the base element further comprises two support brackets and a transverse boom configured to couple to the two support brackets.

11 . The industrial truck according to claim 10 , wherein the second suspension is positioned between the transverse boom and the stand-on element.

12 . The industrial truck according to claim 1 , wherein the stand-on platform is configured to be adjusted about the first pivot axis between an extended position and a stowed position, wherein in the extended position the stand-on element extends substantially horizontally, and wherein in the stowed position the stand-on element extends substantially vertically.

13 . The industrial truck according to claim 6 , wherein the spring force of the first suspension is different than the spring force of the second suspension.

14 . The industrial truck according to claim 1 , wherein the first suspension comprises at least one of a steel spring, a coil spring, a plate spring, a elastomer spring, and a rubber spring.

15 . The industrial truck according to claim 1 , wherein the second suspension comprises at least one of a steel spring, a coil spring, a plate spring, a elastomer spring, and a rubber spring.

16 . The industrial truck according to claim 6 , further comprising a fastening mechanism configured to releasably fasten the stand-on element to the base element.

17 . The industrial truck according to claim 16 , wherein the spring force of the second suspension is adjustable via the fastening mechanism.
