Industrial truck with a lateral frame opening and a frame-reinforcing door
An industrial truck, such as a counterweight fork-lift truck, has a vehicle frame ( 1 ) with a frame portion ( 2 ) configured to receive a battery block. The frame portion ( 2 ) has at least an upper frame opening ( 2 a ) and a lateral frame opening ( 2 b ). The lateral frame opening ( 2 b ) can be covered by a door ( 3 ) pivotable about a substantially vertical axis (A). The door ( 3 ) is configured to reinforce the frame and can be locked in the closed position by a force-transmitting locking unit ( 4 ). The locking unit ( 4 ) can have a force-transmission element ( 5 ) which receives tensile and pressure forces and can be adjusted in the longitudinal and height direction.
1. An industrial truck, comprising:
a vehicle frame comprising a frame portion configured to receive a battery block, wherein the frame portion includes at least an upper frame opening and a lateral frame opening, wherein the lateral frame opening can be covered by a door that is pivotable about a substantially vertical axis, and wherein the door is configured to reinforce the frame and to be locked in a closed position by a force-transmitting locking unit, wherein the industrial truck is a counterweight fork-lift truck,
wherein the locking unit includes a first force-transmission element configured to absorb tensile and pressure forces, and
wherein the frame portion includes a lower frame opening directly adjoining the lateral frame opening.
2. The industrial truck according to claim 1 , wherein the locking unit includes a second force-transmission element, vertically spaced from the first force-transmission element.
3. The industrial truck according to claim 1 , wherein the locking unit includes a leaf spring which is elastically deformable in a longitudinal direction of the vehicle and is fastened to the vehicle frame and, when the door is in the closed position, fixes a locking pin in a transverse direction.
4. The industrial truck according to claim 1 , wherein the door is coupled to an articulated tie rod that is pivotally fastened to the vehicle frame and acts to limit movement in a right-angled open position of the door.
5. The industrial truck according to claim 2 , wherein at least one of the first and second force-transmission elements is adjustable in a lateral direction and a height direction.
6. The industrial truck according to claim 2 , wherein the door is coupled to an articulated tie rod that is pivotally fastened to the vehicle frame and acts to limit movement in a right-angled open position of the door.
7. An industrial truck, comprising:
a vehicle frame comprising a frame portion configured to receive a battery block, wherein the frame portion includes at least an upper frame opening and a lateral frame opening, wherein the lateral frame opening can be covered by a door that is pivotable about a substantially vertical axis, wherein the door is configured to reinforce the frame and to be locked in a closed position by a force-transmitting locking unit, wherein the industrial truck is a counterweight fork-lift truck,
wherein the locking unit includes a first force-transmission element configured to absorb tensile and pressure forces, and
wherein the force-transmission element is adjustable in a longitudinal direction and in a height direction.
8. An industrial truck, comprising:
a vehicle frame comprising a frame portion configured to receive a battery block, wherein the frame portion includes at least an upper frame opening and a lateral frame opening, wherein the lateral frame opening can be covered by a door that is pivotable about a substantially vertical axis, wherein the door is configured to reinforce the frame and to be locked in a closed position by a force-transmitting locking unit, wherein the locking unit includes a force-transmission element configured to absorb tensile and pressure forces, and
wherein the force-transmission element includes a screwed pin connected to the door and a locking pin screwed onto an end of the pin remote from the door, the locking pin configured to engage the vehicle frame or a component connected thereto and thus being fixable in a longitudinal direction of the vehicle.
9. An industrial truck, comprising:
a vehicle frame comprising a frame portion configured to receive a battery block, wherein the frame portion includes at least an upper frame opening and a lateral frame opening, wherein the lateral frame opening can be covered by a door that is pivotable about a substantially vertical axis, wherein the door is configured to reinforce the frame and to be locked in a closed position by a force-transmitting locking unit, and
wherein the locking unit includes a leaf spring which is elastically deformable in a longitudinal direction of the vehicle and is fastened to the vehicle frame and, when the door is in the closed position, fixes a locking pin in a transverse direction.
10. The industrial truck according to claim 9 , including an active element which automatically bends the leaf spring on closing and is fastened to the door.
11. The industrial truck according to claim 8 , wherein the locking unit includes a lock.
12. The industrial truck according to claim 11 , wherein the lock can be unlocked by a Bowden cable.
13. The industrial truck according to claim 11 , wherein the lock includes a latch fixed to the frame and which, when the door is in the closed position, can be brought into engagement with an axial extension of the locking pin acting as a locking member.
14. An industrial truck, comprising:
a vehicle frame comprising a frame portion configured to receive a battery block, wherein the frame portion includes at least an upper frame opening and a lateral frame opening, wherein the lateral frame opening can be covered by a door that is pivotable about a substantially vertical axis, wherein the door is configured to reinforce the frame and to be locked in a closed position by a force-transmitting locking unit, and
wherein the frame portion includes a lower frame opening directly adjoining the lateral frame opening.
