technical field

The utility model relates to the field of large-scale steel structure hoisting, in particular to a tool for the binding hoisting of box-shaped rods.

Background technique

The hoisting of existing large-scale steel structure truss bridges, truss houses and other truss steel structures generally adopts segmental overall hoisting, truss piece hoisting or loose piece hoisting, but for a single bar weighing nearly 100 Tons of rods are mostly hoisted by single rods during construction. For the hoisting of box-shaped rods, the design of the lifting point is the key to the hoisting. Generally, the hoisting of box-shaped poles adopts the method of setting lifting lugs at the lifting points of box-shaped poles. However, the inside of the box at the lifting points of some box-shaped poles is completely closed, and there are certain difficulties in installing and removing using lifting lugs. Bundled hoisting. At present, the bundled hoisting in the construction field is directly tied with the steel wire rope of the sling. During the hoisting process, the corners of the box-shaped pole will cause shear wear to the steel wire rope of the sling, which greatly shortens the service life of the steel wire rope of the sling.
