Abstract
A hoist apparatus includes branch guide rails with a branch point, the branch point defining a branching point between first and second traveling rails, and the branch guide rails including first guide rails having a cross-section in a first direction, and second guide rails having a cross-section in a second direction and connected to the first guide rails, and a traveling unit configured to travel along the branch guide rails, the traveling unit including first auxiliary wheels configured to roll and contact a first side of the second guide rails.
Claims19
A hoist apparatus, comprising:
- branch guide rails with a branch point, the branch point defining a branching point between first and second traveling rails, and the branch guide rails including:
- first guide rails having a cross-section in a first direction, and second guide rails having a cross-section in a second direction and connected to the first guide rails;
- and a traveling unit configured to travel along the branch guide rails, the traveling unit including first auxiliary wheels configured to roll and contact a first side of the second guide rails, wherein the first side of the second guide rails is a top surface of the second guide rails.
A hoist apparatus, comprising:
- branch guide rails with a branch point, the branch point defining a branching point between first and second traveling rails, and the branch guide rails including:
- vertical guide rails having a cross-section in a vertical direction, and
- horizontal guide rails having a cross-section in a horizontal direction and connected to the vertical guide rails;
- and
- a traveling unit configured to travel along the branch guide rails, the traveling unit including vertical wheels configured to roll and contact a top surface of the second guide rails, and horizontal wheels configured to roll and contact a side surface of the second guide rails.
A hoist apparatus, comprising:
- branch guide rails with a branch point, the branch point defining a branching point between first and second traveling rails, and the branch guide rails including:
- first guide rails branching into two directions at the branch point, and
- second guide rails on the first guide rails, the second guide rails branching into two directions at the branch point and being perpendicular to the first guide rails;
- and
- a traveling unit configured to travel along the branch guide rails, the traveling unit including auxiliary wheels positioned to contact only one side of the branch guide rails.
