Description

Multipurpose crane

The present invention relates to a multipurpose cranes, and more particularly to a multipurpose cranes, and more particularly, to a multipurpose cranes which are arranged at right angles to a girder as well as a long cargo placed parallel to the girder by a very simple operation of detaching an intermediate portion of the first sling belt and the second sling belt It is very easy to carry, assemble and disassemble. In addition, when load on the first sling belt and the second sling belt is applied to the first sling, The first hoist, the second hoist, and the pivoting rails provided with the first hoist and the second hoist are pivoted about the hinge axis, while the belt and the second sling belt are pulled along the lower shape of the lifting body.

Generally, a yacht lifting device is installed in a fishing pier, a coast, a dock (election), etc. (hereinafter collectively referred to as a "dock") to lift a ship to the sea or to transport a sea ship to a breakwater or land, And it is used to prevent damage and sinking by evacuating the ship to safety zone even in bad weather.

Conventional prior art related to such a yacht lifting device is disclosed in Korean Registered Patent No. 10-0503918 as 'Fixed Fishing Vessel Yang' and Korean Registered Patent No. 10-0853291 'Cranes'.

However, since the above-mentioned prior art is limited to the lifting work of small and light small ships in the cantilever manner, it is not possible to raise the vessels of the small and medium-sized vessels, and it is difficult to lift high-grade vessels and yachts having complicated structures, And there is a high risk of damage and breakage of the ship due to vibration or shaking.

In order to solve this problem, Korean Patent No. 10-1068012 has been developed, in which a horizontal member is coupled to an upper portion of a vertical member of a structure, a wheel is provided at a bottom portion, and a ship is placed on a band connected to an upper hoist As shown in FIG.

However, such a conventional crane is a hoistable structure only when the upper left portion horizontal member, the upper right portion horizontal member and the yacht corresponding to a pair of girders are arranged in a line. That is, to lift the yacht, the yacht must be placed side by side between the upper left and upper right horizontal members so that a pair of bands can grip the two parts of the yacht.

The long length of the article arranged at right angles to the upper left horizontal member and the upper right upper horizontal member can not be relieved by the conventional crane structure and thus the conventional crane can not provide the goods which can be lifted depending on the shape and position of the lifted article Limited.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a sewing machine for sewing a sewing machine, And to provide a multi-purpose crane capable of lifting a long cargo.

Another object of the present invention is to provide a multi-purpose crane in which a pair of girders are not twisted and the overall structure of the main frame is simple and highly stable.

It is still another object of the present invention to provide a multipurpose cranes in which a plurality of low beams, girders, and trusses constituting a main frame are partitioned.

Another object of the present invention is to provide a sewing machine and a sewing machine in which a first sling belt and a second sling belt are pulled along a lower shape of a crown when a load of a crown is applied to a first sling belt and a second sling belt, And the pivot rails provided with the pivot rails are pivoted about the hinge axis.

It is a further object of the present invention to provide a multipurpose cranes in which one low beam is three-point supported by a steering wheel and a driving wheel.

To accomplish the above object, according to the present invention, there is provided a multipurpose cranes, comprising: a main frame having a pair of girders arranged parallel to the top; Steering wheels respectively installed on a lower side of the main frame; Traveling wheels respectively installed on the lower side of the main frame; A pivotal rail installed in each of the pair of girders and extending along the longitudinal direction of the girder; A pair of first hoists installed on a pivotal rail of one of the pair of pivotal rails; A first sling belt having opposite ends connected to a pair of first hoists; A pair of second hoists installed on the other of the pair of pivotal rails; And a second sling belt having opposite ends connected to a pair of second hoists; The first sling belt and the second sling belt are provided so that a central portion thereof is detachably attached; When the long length cargo placed in parallel with the girders is transported, the central portion of the first sling belt and the central portion of the second sling belt are separated, and the lower ends of the first sling belts are separated from the lower ends of the adjacent second sling belts As shown in FIG.

Another feature of the multi-purpose crane of the present invention is that the main frame includes a low beam for a steering wheel on which a steering wheel is installed, a low beam for a traveling wheel on which a traveling wheel is mounted, a low beam for a steering wheel, A pair of low beams consisting of a connecting low beam connected to the beam; A column provided between both ends of the low beam and the girder to support the girder; A girder having a first column girder and a second column girder provided at the upper end of the column, a connecting connecting girder having both ends connected to the first column girder and the second column girder, and an extending girder connected to the first column girder; And a truss which is installed on a pair of second column girders and supports a pair of girders.

Another feature of the multipurpose crane of the present invention is that the truss comprises a first upper truss whose one end is fixed to the upper surface of one of the pair of girders and a second upper truss whose one end is fixed to the upper surface of the other of the pair of girders, An upper truss made up of a second upper truss coupled to the first upper truss; A first low truss which is fixed to the lower surface of one of the pair of girders and a second low truss whose one end is fixed to the lower surface of the other one of the pair of girders and the other end is joined to the first low truss And a low truss.
