Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a lifting frame for civil construction. Background Art

[0002] Construction hoists are mainly used in various types of high-rise and super-high-rise buildings in cities. This is mainly because it is very difficult to use trusses and gantry frames to complete operations at such building heights. In recent years, with the continuous increase in building heights, the demand for construction hoists with large erection heights has also been increasing. In addition to being used in high-rise buildings, construction hoists can also be used in the construction of bridges. In addition, it can also be used in cooling towers of large chemical plants, chimneys of power plants, radio and television towers, coal mines and other construction occasions. Construction hoists have become an indispensable mechanical equipment in the construction industry.

[0003] In many construction sites such as large chemical plant cooling towers, power plant chimneys, radio and television towers, and coal mines, workers are required to manually apply cement evenly to the outer walls of the completed buildings for reinforcement. However, most cement mixing is done underground, so the transportation of the mixed cement can only be done by manual handling, which greatly reduces the work efficiency of the workers. Since cement is heavy and easy to solidify, it increases the fatigue of the workers in handling. Utility Model Content
