Building tower crane steel bar clamp

Technical Field

The utility model relates to a building tower crane steel bar clamp.

Background

Reinforcing bars are widely used in various building structures due to their own properties. Especially large, heavy, light thin-walled and high-rise building structures.

When high-rise houses are built, the steel bars are usually required to be hoisted to the position to be built, and for better hoisting, a crane hoisting end usually adopts bifurcated double hooks to carry out auxiliary hoisting on the steel bars.

However, the existing bifurcated double hooks have some problems in the use process, because the double hooks are connected by adopting steel wires, the stability is poor, and particularly in the high-altitude operation, the high air flow is relatively unstable, so that the steel bars shake, the danger is very easy to occur, and therefore, a steel bar clamp with relatively high lifting stability and lifting safety is needed.
