Description

Technical Field

[0001] The utility model relates to the field of pedestal structure hoisting devices, and more specifically, to an adjustable and assembled universal pedestal hoist. Background Art

[0002] The pedestal foundation is a common foundation form in bridge construction, port terminal construction, and offshore wind power construction. With the continuous innovation and leapfrog development of construction technology, more and more special-shaped pedestals on the water have adopted the construction method of prefabrication before hoisting and installation. Large-span special-shaped pedestal foundations on the water are often large in size and weight, and the cross-section of the special-shaped pedestal is mostly irregular in space and has arc corners. It is difficult to balance the various lifting points and evenly distribute the weight of the pedestal during the hoisting process using the hoist. In addition, because the pedestal is prefabricated in blocks, there are usually multiple special-shaped pedestal foundations of different sizes and shapes. The pedestal hoist is difficult to design and cannot be used in rotation. There are a series of problems such as high design difficulty, complex hoisting conditions, high construction risks, and difficulty in multiple adjustments and turnover. Utility Model Content
