Detailed Description

Example 1

As shown in fig. 1 and 2, the present embodiment provides a sand and stone shipping box for a port, which includes a box door 1, a box body 2, a balance beam, a steel wire rope 5 and a chain ring, wherein the box body 2 is in a rectangular parallelepiped shape with an open top, two box doors 1 are symmetrically arranged on two sides of the bottom of the box body, and the box door 1 on each side is connected with the edge of the bottom of the box body through 3 sets of hinge points. The balance beam comprises a lower balance beam 3 and an upper balance beam 4, two groups of guide pulleys 401 are arranged in the upper balance beam, two steel wire ropes 5 respectively penetrate through the corresponding guide pulleys, and the tail ends of the steel wire ropes are connected with two first lower beam lifting lugs 301 arranged on the upper portion of the lower balance beam 3.
