More Information
Summary:The utility model discloses a fixed crane with a vertical column and a rotary arm. The utility model is characterized in that a set of fixed pulleys [13] are arranged at the lower part of a horizontal travel mechanism [8] which is on a cross beam [5], and a crane pulley block can be formed by the fixed pulleys which are concatenated with a hook assembly [7] through a steel cable [14]. The fixed end of the steel cable can also be concatenated with a tensile sensor [12], so that the display and the control of crane moments can be realized. Under the premise of the same structural parameters with an original crane, the utility model has the advantage that the crane amount and the lifting height are greatly enhanced.
