To a remotely adjustable hypothesis lifting device.

In a construction site, it is common to use a lifting device when lifting a large load of temporary construction materials or construction materials to a desired height position or transporting a high load temporary construction platform to a predetermined height position at a loading dock.

For example, formwork is installed on the outer wall of the structure at the time of construction of the building structure, in this case, in order to perform the work smoothly on the outer wall of the structure, install a temporary acting as a kind of work scaffolding. Such constructions are additionally installed to correspond to the number of floors as the number of floors of the structure increases, conventionally, an elevated construction platform which is lifted up by the crane as a whole when constructing a high-rise building structure was used.

However, the use of a crane increases the time and expense required for the work, there is a problem that causes the construction progress.

Accordingly, the applicant of the present invention performs the lifting step of the temporary lifting rod without using a crane by the lifting base material stepped up and down the profile in the Republic of Korea Patent No. 0743520 (name: temporary lifting device and temporary lifting method using the same). I've presented a technique to make it possible.

Such a registered patent is intended to elevate the profile step by step while the elevator base is engaged to the engaging projection formed at a predetermined interval along the vertical direction to the profile of the temporary table. In particular, the lifting material is selectively engaged with any one of the protruding projections while moving forward or backward along the lifting direction through the configuration of the hydraulic cylinder and the hook.

Therefore, it is possible to raise and lower the temporary stage step by step safely and easily.

In addition, the applicant of the present invention has filed a patent application of the Republic of Korea Patent Application No. 10-2007-0113115 and 10-2007-0113116. The patent application proposes a temporary lifting device that is easy and easy to install or dismantle the profile in the lifting operation means because the guide arm can be opened or closed.
