Fig. 1 is a perspective view of a multi-purpose hoist apparatus according to a preferred embodiment of the present invention, and Fig. 2 is a front view of Fig. 1. Fig.

1 and 2, a multi-purpose hoist apparatus according to a preferred embodiment of the present invention includes a support frame 30, a first hoist 10 and a second hoist 30 disposed apart from each other in the support frame 30, 20).

The support frame 30 has a pair of metal plates arranged parallel to each other and connected to each other by a plurality of fixing pins 15, 17 and 25 to maintain mutually spaced states.

The first hoist 10 is for lifting a heavy object such as a fishing boat or the like, and is configured to have a hoisting capacity of, for example, about 10 tons. The second hoist 20 is for lifting a relatively light object such as fishing nets or the like, and has a relatively small hoisting capacity as compared with the first hoist 10. For example, the second hoist 20 is configured to have a hoisting capacity of about 1 to 2 tons.

Specifically, the first hoist 10 preferably includes a plurality of first hoisting motors 13 and a first hoist 11 hoisted by the first hoisting motor 13 and hanging a load at the end thereof And a chain (12). The second hoist 20 is constituted by a second hoisting motor 23 having a hoisting capacity relatively smaller than that of the first hoisting motor 13 and a second hoisting motor 23 hoisted by the second hoisting motor 23, And a chain (22) to which a second hook (21) is connected. Although not shown in the drawings, the first hoist 10 and the second hoist 20 may be equipped with a chain box for accommodating the chains 12 and 22, respectively.

The multipurpose hoist apparatus according to the present invention is movably installed on a horizontal moving rail 100 of an 'H' beam type provided in a conventional hoisting machine. The first hoist 10 and the second hoist 20 are preferably disposed on both sides of the support frame 30 in consideration of the mobility of the multi-purpose hoist.

On the upper part of the support frame 30, a rail moving member 14, 24 having a plurality of rollers is movably disposed along the horizontal moving rail 100. The rail shifting members 14 and 24 are preferably provided on both sides of the support frame 30 in order to distribute the load of the first hoist 10 and the second hoist 20, respectively.

The rail moving members 14 and 24 provided on both sides of the support frame 30 are supported by first fixing pins 15 and 25 fastened to cross a pair of metal plates constituting the support frame 30 Is fixed to the frame (30).

A first hoisting motor 13 belonging to the first hoist 10 and a second hoisting motor 23 belonging to the second hoist 20 are mounted on the lower part of the support frame 30. The first hoist motor 13 is mounted to the support frame 30 by the first support rod 16. [ The upper end of the first support rod 16 is fixed to the support frame 30 by a second fixing pin 17 fastened to cross a pair of metal plates and the lower end supports the first hoist motor 13 . Here, the second fixing pin 17 is located at a lower position relative to the first fixing pin 15.

Since the second hoisting motor 23 is relatively small in capacity as compared with the first hoisting motor 13 of the first hoist 10, the vertical width of the support frame 30 is relatively larger than that of the first hoisting motor 13 The necessary supporting performance can be secured. According to this structure, the second hoisting motor 23 can be disposed close to the upper side of the support frame 30, and the first fixing pin 25 for fixing the rail shifting member 24 can be preferably disposed on the second hoisting- It is also possible to use the fixing member 23 as a fixing member. That is, the second hoisting motor 23 is mounted on the support frame 30 by the second support rod, and the upper end of the second support rod 26 is fixed to the support frame 30 by the first fixing pin 25 And the lower end supports the second hoisting motor 23.

The first hoisting motor 13 and the second hoisting motor 23 are installed on the support frame 30 via the first support rods 16 and the second support rods 26, So that it can be easily attached and detached.

The multi-purpose hoist apparatus having the above-described configuration is mounted on a horizontal moving rail provided at the upper part of a lifting device of a JIB, for example, and is used for lifting a relatively heavy object and for lifting a light object.

That is, when lifting the fishing boat, for example, the first hoist 10 having a large hoisting capacity of 10 tons is driven to slowly lift the fishing boat, and when lifting a fish net containing fish other than fishing boat, The second hoist 20 having the small hoist capacity can be driven to perform the hoisting operation at a high speed, thereby improving the working efficiency.

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. It should be noted, however, that the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.
