Said body feed tank is made up of casing, steel rope, suspension ring and wire clips, and said suspension ring are fixed on 4 angles, said casing top, and said steel rope is affixed through said wire clips and said suspension ring;

Said platform is made up of bracket beam, secondary beam, side bar peace dummy cow leg, and 2 said bracket beams are welded on the two ends of 2 said side bars, and said secondary beam weldering is welded in the space between said bracket beam and the said side bar, and said platform bracket is installed in the two ends of said bracket beam;

Said winding type electric block is installed in the crossbeam of said gantry support body, and said winding type electric block is connected with the steel rope of said body feed tank through hook.

This practical beneficial effect is: the technical approach with existing turnover material has following characteristics:

1. new-type turnover material method in the building operation.

2. reduce the operation that the tower crane dress hangs template, save the time of turnover material.

3. need not to install the material platform, the turnover material is convenient, flexible.

4. gantry support body peace platform utilizes bracket to be fixed in the hole to be provided of pit shaft body of wall, reduces fitting operation.

5. adopt electric block formula power-lift mode, swift to operate, and the comfort feature that provides vertical and horizontal to operate.

6. the protection platform is installed in the bottom, improves safety.

7. satisfy the construction process requirement that supports three of plates in the existing top board.

The specific embodiment

further specify below in conjunction with accompanying drawing and the specific embodiment technical scheme to the utility model.

Shown in Fig. 1-4, this practical a kind of pit shaft material raising legs comprises gantry support body 1, body feed tank 2, platform 3 and winding type electric block 4,

Wherein, support body 1 column in gantry is made up of column 5, gantry bracket beam 6 and

crossbeam

7,2 root posts 5 and gantry bracket beam 6 welding assembly triangularity supports, then the two ends of crossbeam 7 and triangular supports is connected with nut fixing, gantry bracket beam 6 interior installation brackets 8;

Body feed tank 2 is made up of casing 9, suspension ring 10, steel rope 11 and wire clips 12, on 4 angles of casing 9 upper ends suspension ring 10 is set, and two steel ropes 11 are fixing with suspension ring 11 with wire clips 12 respectively, guarantees during installation that two steel rope 12 length are consistent;
