2. Description of the Related Art For example, in a fluorine processing factory, the temperature is controlled to be higher than 300 ° C. for powder metallurgy molding of fluororesin or for firing and sintering when coating with fluorine. Fluorine processed products (hereinafter simply referred to as "processed products") etc. need to be put in and taken out of the heating furnace. Generally, such a processed product is placed on a carrier or the like, put into a high-temperature heating furnace, and taken out from the heating furnace.

[0003] Conventionally, in the work of moving the carrier into and out of the heating furnace, an operator pushes the carrier into the heating furnace by using a long rod member while avoiding heat in the furnace, and from the inside of the heating furnace. It was done by pulling out. However, the work in which the worker pushes and pulls the distant carrier while holding the long rod member is a heavy work that requires a lot of labor, and there is a problem that the work efficiency is low.

In order to improve these problems, it has been proposed to provide a dedicated equipment such as a chain drive on the floor of the passage leading to the inside of the heating furnace. According to this, since the carrier can be moved to the heating furnace by the chain drive device, it is excellent in that the burden on the operator can be significantly reduced, but the cost is high because the equipment is extremely large. In addition, there is a problem that the layout cannot be changed easily.

The present invention has been devised in view of the above problems, and when moving a distant carrier to an arbitrary position, the work efficiency is reduced while reducing the burden on the operator. It is an object of the present invention to provide a work device for moving a transfer base and a work vehicle including the work device that can be improved and can easily cope with cost problems and layout changes.
