Problems solved by technology

[0003] When placing the test piece on the test ship, it is often necessary to place the test piece at a designated position. When placing the test piece, it is necessary to adjust its direction and position and the height of the test piece. In the prior art, the gram pendulum is usually used Put the test piece, and the angle of the test piece is not easy to operate
Its operation is cumbersome, which reduces the working efficiency of the Crane Crane. The Crane Crane can only lift the next test piece after placing the test piece.

Description

technical field [0001] The invention relates to the technical field of crane auxiliary equipment, in particular to a lifting device for lifting a test piece by order. Background technique [0002] Crane, also known as marine crane or marine crane, is a large deck machinery on a ship. It is a kind of equipment for loading and unloading cargo on ships. [0003] When placing the test piece on the test ship, it is often necessary to place the test piece at a designated position. When placing the test piece, it is necessary to adjust its direction and position and the height of the test piece. In the prior art, the gram pendulum is usually used Put the test piece, and the angle of the test piece is not easy to operate. Its operation is cumbersome, has reduced the working efficiency of the gram crane, and the gram crane can only lift the next test piece after the test piece has been placed. Contents of the invention [0004] Aiming at the shortcomings in the above-mentione...
