Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight and long span crane garter.

[0002]

2. Description of the Related Art A crane garter for hoisting and traversing a gondola with a crane is composed of traveling frames at both ends that automatically travel and a beam frame bridged between them. It was limited to short ones.

[0003]

Since the conventional self-propelled crane garter has a large span and becomes a heavy object, it is necessary to construct intermediate legs which are in the same plane as the traveling frame at several intermediate positions. Therefore, the weight is further increased and a large amount of power is required for traveling.

Further, for example, when a vehicle, a container, or the like is hoisted and arranged on an upper floor having a second floor, the blow-through portion for the lower end running portion of the intermediate leg to reach the ground must be cut out on the upper floor. There were drawbacks such as not being able to use the upper floors to fill the entire site.

The present invention provides a crane garter which is a self-propelled crane garter and has a very long span, and which is extremely lightweight and allows the upper floor of the second floor to be effectively used to fill the site without cutting out the floor of the second floor. It is intended.

[0006]

[Means for Solving the Problems] Beams in which rolling wheels at the lower end of the self-propelled frame are mounted on track rails provided on both side edges of the site, and a bridge is formed between the pair of self-propelled frames at the height of the second floor ceiling. At several points of the frame, a structure will be used in which a center pillar, which supports the wheels on the second floor, is supported at the lower end.

[0007]

The present invention is a self-propelled garter that has a beam frame configured on the ceiling of the second floor with a center pillar hanging from the lower end of the wheel that contacts the second floor. Even if it is made long, the weight of the beam frame hangs down, and the middle pillars where the lower end touches the second floor is shared by the second floor so that it can be supported, resulting in extremely lightweight overall and stable garter movement. Since it does not require intermediate legs to reach the ground, the cutout part of the second floor does not require anything other than the unloading pit for one vehicle, for example, and the second floor has the same area as the space above the ground and fills the site. Space available.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a crane garter for use in a two-story parking lot having a large site area as shown in FIG.
Self-propelled frame 3,3 on which bottom wheels 2,2,2,2 are mounted
A structure in which a beam frame 4 is bridged at the height of the ceiling on the second floor, and a middle pillar 6 is hung at several points of the beam frame at the lower end of which a wheel 5, 5 that contacts the second floor 7 is pivotally attached. It is what Therefore, even if the span of the self-propelled frame becomes large and the weight becomes large, the center pillar that moves along with the self-propelled portion bears and supports the load, so that the entire weight becomes light and the traveling power is small.

Therefore, the girder frame is equipped with a pallet lift for one vehicle and a gondola 8 for traversing freely, and by opening an unloading pit for one vehicle on the second floor, the second floor is on the ground site. The same space as the area can be used as a parking space for cars.

[0010]

EFFECTS OF THE INVENTION According to the present invention, a crane garter for storing a car or a container on the second floor is extremely lightweight to enable stable traveling movement with a small amount of power, and a cutout portion is not required on the second floor so that the space on the second floor is not required. There is an effect that all can be used in almost the same area as the ground site area.
