Description

&Quot; ELEVATED-UP / DOWN TYPE TRANSPORTING CART "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lifting / lowering carriage, and more particularly, to a lifting / lowering carriage that can be lifted up to the height of a truck by itself when loading cargo in a truck.

Generally, a freight cargo is used when the cargo is carried and loaded on a truck or the like. These cargo trucks are configured to be capable of ascending and descending the loading platform to load the loaded cargo onto the truck.

However, in the case of a conventional freight car, the loading platform of the freight car is simply raised up to the height of the loading bay of the truck, so the cargo must be moved again to the position where the cargo is placed on the loading platform of the truck.

In addition, it is often the case that freight buggies must be loaded on the truck's loading box and moved to another location together with the freight. In this case, the freight buggers must be lifted using a forklift or other apparatus, Rise and work time increase.
