DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0022] As Figures 1 to 3 shown.

[0023] A superlift counterweight platform for a crawler crane of the present application includes:

[0024] The storage platforms 1, right counterweight platforms 2, middle counterweight platforms 3, and left counterweight platforms 4 distributed at circumferential intervals. There are walking tracks 5 for the crawler crane to walk on both sides of the middle counterweight platform 3. The walking tracks 5 are distributed in two, and there is a gap between the walking tracks 5 and the middle counterweight platform 3.

[0025] The counterweight blocks of the crawler crane are scattered and placed on the placement platforms 1, right counterweight platform 2, middle counterweight platform 3, and left counterweight platform 4 that are circumferentially distributed. When the crawler crane rotates circumferentially during hoisting on the traveling track 5, after the crawler crane rotates to correspond to any one of the placement platform 1, right counterweight platform 2, middle counterweight platform 3, and left counterweight platform 4, the counterweight blocks are replaced. At this time, the counterweight blocks can increase or decrease the counterweight between any one of the placement platform 1, right counterweight platform 2, middle counterweight platform 3, and left counterweight platform 4 and the crawler crane. Since the counterweight blocks can increase or decrease the counterweight between any one of the circumferentially distributed placement platform 1, right counterweight platform 2, middle counterweight platform 3, and left counterweight platform 4 and the crawler crane, it avoids the situation where the local load on the deck surface of the offshore platform is too high due to the concentrated placement of the counterweight blocks in one place, and solves the problem affecting the platform safety.
