Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manual type turntable device,

The present invention relates to a heavy-weight hand-held turntable device, and more particularly, to a hand-held turntable device capable of easily rotating a heavy weight of tens to hundreds of tons in a manual manner, And more particularly, to a heavy-weight hand-held type turntable device which can be economically secured with easy partial maintenance.

In general, there are proposed facilities for transporting heavy or ultra-heavy goods having loads of several tens of tons or several hundreds of tons at installation points or transfer points.

For example, in order to transport heavy and bulky heavy goods such as hull blocks in the process of manufacturing a ship or high-power generators for installing power generation facilities, lifting equipment is lifted by a lifting facility, Afterwards, the direction of travel is changed to carry it to the installation point.

In the process of transferring heavy objects to such an installation or transfer point, a turntable device is used to change the direction of the heavy object.

As an example of a conventional turntable device, there is a structure in which a vertical lift is provided on a bogie, an upper plate, a middle plate, and a swing bar for X-axis Y-axis operation are installed on the lift, and a Z-direction rotary turntable is provided on the upper plate. And a lug is attached to the lower portion.

However, in the conventional art as described above, the rotation of the table plate, which is rotatably installed in the workplace, is controlled through a drive device such as a motor or a hydraulic cylinder. Since the structure is complicated and integrated with the bogie, The lifting device can not be applied, and in particular, there is a problem that it can not be used as a turntable device of extremely heavy weight.

Meanwhile, in another embodiment of the turntable device of the related art, there has been proposed an apparatus for inserting a tree in a round shape in the form of a timber bar, placing a Teflon slide on the top thereof, and applying a physical force using a manual chain winch .

However, even though friction is small to rotate several hundreds of tons of ultra-heavy materials, even a Teflon-based slide is subject to considerable friction, which requires a lot of rotation moment and requires a large amount of manpower and equipment.
