Industrial truck with two wheel arms and method for assembling the industrial truck
An industrial truck has a vehicle frame ( 1 ), a lifting framework ( 4 ) attached to the vehicle frame ( 1 ) and two wheel arms which extend in the horizontal direction. The wheel arm is connected to the vehicle frame ( 1 ) and at the free end of which at least one running wheel ( 3 ) is arranged. Each wheel arm has a first longitudinal structural part ( 2 ) which is a component of the vehicle frame ( 1 ) and has a second longitudinal structural part ( 5 ) which is a component of the lifting framework ( 4 ). The running wheel ( 3 ) is arranged on the first longitudinal structural part ( 2 ). A screwed connection is provided for connecting the first longitudinal structural part ( 2 ) to the second longitudinal structural part ( 5 )
1. An industrial truck, comprising:
a preassembled vehicle frame unit including a pair of spaced first longitudinal structural parts as components thereof, each of the pair of spaced first longitudinal structural parts extending from a respective location on the vehicle frame, with each first longitudinal structural part having a running wheel on an outer end thereof; and
a preassembled lifting framework unit attached to the vehicle frame unit and including a pair of spaced second longitudinal structural parts as components thereof, each of the pair of spaced second longitudinal structural parts extending from a respective location on the lifting framework unit,
wherein the vehicle frame unit is fixedly and non-movably connected to the lifting framework unit such that each of the first longitudinal structural parts respectively rigidly connects to each of the second longitudinal structural parts,
wherein spaced wheel arms of the industrial truck are formed by the first longitudinal structural parts and the second longitudinal parts respectively connected to each other, the spaced wheel arms having one of the running wheels at a free end of each arm, and
wherein the second longitudinal structural part forms an inner side of the wheel arm.
2. The industrial truck according to claim 1 , wherein the first longitudinal structural part forms an outer side of the wheel arm.
3. The industrial truck according to claim 1 , wherein the second longitudinal structural part is made from cast metal.
4. The industrial truck according to claim 3 , wherein the second longitudinal structural part is made from cast steel or from ductile cast iron.
5. The industrial truck according to claim 1 , wherein the first longitudinal structural part is made from sheet steel.
6. The industrial truck according to claim 1 , including a screwed connection for connecting the first longitudinal structural part to the second longitudinal structural part.
7. The industrial truck according to claim 1 , including an at least approximately vertical mast profile of the lifting framework connected rigidly to the second longitudinal structural part.
8. The industrial truck according to claim 1 , wherein each of the pair of first longitudinal structural parts extends from the vehicle frame unit at the respective location on the vehicle frame unit and each of the pair of second longitudinal structural parts extends from the lifting framework unit at the respective location on the lifting framework unit, and wherein the respective locations on the vehicle frame unit are separate from the respective locations on the lifting framework unit.
9. The industrial truck according to claim 1 , wherein the first longitudinal structural parts extend from a central region of the vehicle frame unit.
10. The industrial truck according to claim 1 , wherein the first longitudinal structural parts constitute supporting structural parts of the vehicle frame unit.
11. The industrial truck according to claim 1 , wherein each of the pair of first longitudinal structural parts extends from the vehicle frame unit at the respective location on the vehicle frame unit in a forward direction of the industrial truck and each of the pair of second longitudinal structural parts extends from the lifting framework unit at the respective location on the lifting framework unit in the forward direction of the industrial truck.
