Technical Field
The invention relates to the technical field of floor plate transportation machinery, relates to a ox-type forklift and a using method thereof, and particularly relates to an ox-type forklift suitable for Tian Ziban transportation and a using method thereof.
Background
Fork trucks are industrial handling vehicles, and refer to various wheeled handling vehicles that perform handling, stacking, and short-distance transport operations on piece pallet goods. The forklift is one of the most widely used mechanical devices in the industrial field, and the forklift is required to be used for a large amount of goods handling work in warehouses, factories or construction sites. Current fork truck is mainly divided into two types because of the characteristics of its operation: counterbalanced forklifts and ground-ox forklifts. However, both of these types of forklifts have certain disadvantages: 1. although the balance weight type forklift has better applicability, not only can be suitable for transporting III-shaped ground tables, but also can be suitable for transporting field-shaped ground tables, due to the structural arrangement characteristics, the size of the balance weight type forklift is larger, the turning radius is larger, and the balance weight type forklift is difficult to flexibly use in a narrower space; 2. although the ox-type forklift is small in turning radius, flexible and convenient, the fork arms of the ox-type forklift are directly contacted with the ground through the fork arm supporting wheels, and the ox-type forklift can only transport a III-shaped floor plate. The bearing capacity of the III-shaped floor board is far lower than that of the field-shaped floor board, and meanwhile, the cost of the field-shaped floor board is higher, so that the III-shaped floor board and the field-shaped floor board are often matched for use in a factory, and in order to meet the requirements of the III-shaped floor board and the field-shaped floor board, two types of forklifts are often required to be matched, so that the equipment cost is greatly increased, and the use is inconvenient.
Therefore, it is of great practical significance to develop a forklift structure that can overcome the inherent defects of counter-weight forklifts and ground-ox forklifts.
