Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an elevating crane capable of unloading and unloading construction materials, equipment, and the like on a construction work site or the like to an upper floor or a top floor.

[Prior Art] Conventionally, as this type of lifting crane, FIG. 3 (A)
As shown in (1), the lifting frame main body 4 is moved up and down along the guide rail 1, and materials and the like are lifted by the crane 17 installed in the frame main body 4.

[Problems to be Solved by the Invention] However, the above-described conventional lifting crane is also apparent from FIG. 3 (B) when the frame body 4 is positioned at the top of the hoistway and the crane 17 is turned. As described above, there is a problem that the beam 17a of the crane 17 contacts the scaffold 18 and the load cannot be directly dropped on the top floor of the building.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to provide an elevating crane capable of directly lowering or discharging a load to the top floor.

Means for Solving the Problems A lifting crane according to the present invention has a guide rail erected along the outside of a multi-layer temporary structure such as a bitty scaffold temporarily provided on a side of a building, and a lifting frame along the guide rail. In a crane in which a main body is mounted so as to be able to move up and down and a hanging beam is pivotably mounted on the lifting frame body, when the lifting frame body is located at the uppermost portion of a hoistway, the hanging beam is moved to the multilayer temporary object. And when the lifting frame body is positioned in the middle of the hoistway, the hanging beam rotates to take in the load to the middle floor of the building. It is characterized in that it can be taken out. Also, a crane in which a guide rail is erected along the outside of the side of the building, a lifting frame main body is mounted so as to be able to move up and down along the guide rail, and a hanging beam is swingably installed on the lifting frame body. When the lifting frame body is located at the top of the hoistway, the suspension beam is configured to be able to make a full turn beyond the upper end of the guide rail,
When the lifting frame main body is located in the middle of the hoistway, the suspension beam is turned so that the load can be taken in and taken out of the middle floor of the building.

Further, the hanging beam, a rotating column rotatably attached to the lifting frame body, a horizontal beam fixed horizontally to the upper end of the rotating column, and a traveling trolley moving along the horizontal beam. And a load suspending hook suspended from the trolley via a wire.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a guide rail,
Is attached to or supported by a multilayer temporary object 3 such as a bitty scaffold or a building body.

Reference numeral 4 denotes a lifting frame main body,
Is mounted so that it can move up and down. Reference numeral 5 denotes a hanging wire, one end of which is connected to the lifting frame main body 4. The hanging wire 5 is wound around a top sheave 6 attached to the upper end of the guide rail 1, and the other end is provided below the guide rail 1 as shown in FIG. The elevating winch 8 is wound around the sheave 7.

Reference numeral 9 denotes a fixed support, which is installed substantially vertically on the elevating frame main body 4 and extends upward. A rotating support 10 is rotatably attached to an upper extending portion of the fixed support 9. The rotary support 10 is rotated by a turning motor 11.

When the lifting frame main body 4 is moved up along the guide rails 1 and positioned at the upper end of the hoistway, the rotary support 10 extends upward from the upper ends of the guide rails 1 and the multilayer temporary object 3. Length.

A horizontal beam 12 as a suspension beam is fixed to the upper end of the rotating column 10, and rotates with the rotation of the rotating column 10.

A traveling trolley 13 is installed on the horizontal beam 12 so as to be freely movable. On the traveling trolley 13, a load hanging hook 15 is suspended via a wire 14.
To move up and down.

Since the lifting crane according to the present embodiment is configured as described above, as shown in FIG. 2, when the rotating column 10 is rotated by ascending to the uppermost position, the horizontal beam 12 causes the guide rail 1 and the multilayer temporary mounting. It is possible to turn over the upper end of the object 3 and directly unload or lift the load on the top floor of the building.

In addition, it is also possible to change a use to a lift by removing a crane part and attaching a carrier as needed.

[Effects of the Invention] 1) Since it is possible to make a full turn while avoiding guide rails and multilayer temporary objects at the top of the hoistway, loads such as building materials can be directly loaded and unloaded on the top floor of the building.

2) It is possible to take in and take out the load to the middle floor.
