Abstract
A maintenance lift (MTL) apparatus includes an auxiliary track in contact with a travel rail forming a movement path of a transfer apparatus to extend a movement path of the travel rail and supporting the transfer apparatus put into the travel rail or introduced from the travel rail, a lift part adjusting its length in a vertical direction or moved to move the auxiliary track so that the auxiliary track is disposed at a first position where the auxiliary track is adjacent to a floor surface as compared with the travel rail and the transfer apparatus is introduced or carried out to the outside or is disposed at a second position where the auxiliary track is in contact with the travel rail.
Claims14
A maintenance lift (MTL) apparatus comprising:
- an auxiliary track in contact with a travel rail forming a movement path of a transfer apparatus to extend a movement path of the travel rail;
- a lift part configured to adjust a length of the lift part in a vertical direction or elevated or lowered to move the auxiliary track such that the auxiliary track is disposed at a first position where the auxiliary track is adjacent to a floor surface as compared with a position of the travel rail or is disposed at a second position where the auxiliary track is in contact with the travel rail;
- and
- a body part provided with the lift part, the body part including wheels to move on the floor surface,
- wherein the auxiliary track is configured to be elevated to the second position, and the transfer apparatus is configured to move between the travel rail of a position to which the body part is moved and the auxiliary track, and
- wherein the lift part includes:
- a frame on which the auxiliary track is installed;
- and
- elevating or lowering members provided on the body part that include a cylinder adjusting a height of the frame.
