Description

Portable gantry crane

technical field

The utility model relates to a simple hoisting device, in particular to a portable gantry hoisting frame.

Background technique

As we all know, in the production work such as replacing transformers and adding new lines, loading and unloading transformers and poles is a very time-consuming and laborious work. Because these objects are large in size and very heavy, it is very difficult to carry them by manpower alone. Big security risk. For example, when unloading a transformer on a car, it is necessary to set up two long cross-arms on the car as rails, and then use a rope to cover the transformer, and use manpower to drag the transformer to be unloaded from the car. The work is very laborious, and There are great security risks.

Therefore, designing a kind of labor-saving, safe portable gantry lifting frame is a technical problem to be solved at present.

Contents of the invention

The technical problem to be solved by the utility model is to provide a portable gantry lifting frame.

The technical scheme that the utility model solves its technical problem is:

The portable gantry hoisting frame is composed of a portal hoisting frame and a guide chain. The portal hoisting frame is composed of two columns and a beam. The column and the beam are detachably connected. The base is provided with a downward inclined support between the base and the column, and the guide chain is hung on the middle part of the beam through the ring.

Preferably, a piercing ring is provided at the upper end of the column, the crossbeam is fitted in the piercing ring, and a detachable upward inclined support is provided between the crossbeam and the column.

Compared with the prior art, the utility model has the advantages that it can be assembled and disassembled, is convenient to carry, and ensures construction safety.
