Description

Technical Field

[0001] The present invention relates to a prefabricated floor device for a vertical reach forklift, and more particularly to a prefabricated floor device for a vertical reach forklift that can be disassembled from the vertical reach forklift, thereby being easy to assemble and maintain and stable to drive. Background Art

[0002] Generally speaking, a reach truck or forklift is an industrial vehicle used to lift and transport heavy objects, and is widely used to move goods over short distances such as at construction sites or to load goods in indoor workshops.

[0003] Among such reach forklifts, in a vertical reach forklift, since the driver stands on a seat while driving, the driver who stands for a long time while driving may feel quite tired due to the vibration or impact of the vehicle body while driving.

[0004] Therefore, conventionally, in order to prevent vibration or shock transmitted from the ground during travel of a reach forklift from being transmitted to a floor panel provided on the floor of the driver's seat, elastic bodies such as rubber or springs are simply mounted on the floor panel.

[0005] In this regard, Korean Utility Model Publication No. 20-0128511 (hereinafter referred to as “prior art 1”) “Upright Forklift Footboard Buffer Device” has been disclosed.

[0006] Prior art 1 relates to a pedal buffer device for a vertical forklift, in which a predetermined elastic material is inserted between a bottom plate of a body and a pedal to absorb vibrations transmitted from the ground when the body is driven, and to relieve worker fatigue by buffering and absorbing vibrations and impacts transmitted from the ground to the pedal when the forklift is driven, thereby improving work efficiency and preventing various occupational diseases.

[0007] However, in the prior art 1, only a coil spring (elastic material) is installed at the bottom of the foot pedal arranged on the floor of the driver's seat to absorb the vibration and impact transmitted from the ground to the foot pedal, so there is a problem that the entire foot pedal does not move during driving and shakes according to the position of the driver.

[0008] Meanwhile, in the past, in order to prevent vibration or impact transmitted from the ground when the reach forklift is traveling from being transmitted to the bottom plate set on the floor of the driver's seat, shock absorbers and cylinder guides were installed, and the bottom plate and the like were manufactured using a mold.

[0009] However, when a conventional shock absorber and a cylinder rail are installed and a bottom plate is manufactured using a mold, there is a problem that convenience is reduced due to difficulty in assembly and maintenance, and there is a problem that a large amount of installation space is required in terms of structure, and a driver's space becomes narrow. Summary of the invention
