Large hoisting equipment

Abstract

The invention discloses large hoisting equipment and belongs to the technical field of building equipment. The large hoisting equipment comprises a hoisting seat, a central seat frame and cross beam frames uniformly arranged on the edge of the central seat frame; and the middle portion of each cross beam frame is provided with a sliding rail, the upper end and the lower end inside each sliding rail are provided with sunken openings, each sliding rail is slidably provided with a sliding block, each sliding block is fixed to the corresponding sliding rail through a sliding block main bolt, each sliding block is provided with a protruded block, the lower end of each sliding block is connected with a lifting hook rod, the lower side of each lifting hook rod is provided with a lifting hook embedding hole, a lifting hook is embedded into the corresponding lifting hook embedding hole, and each lifting hook is fixedly installed on the corresponding lifting hook rod through a lifting hook rod bolt. Position change of the lifting hook rods in the large hoisting equipment is simple and rapid, the lifting hook rods can be fixed to any position of the sliding rails, the embedded lifting hooks of multiple hook shapes are adopted, the use performance of the large hoisting equipment is remarkably optimized, and the application field is broadened.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a large hoisting equipment. Background technique [0002] After 2000, China's GDP maintained rapid growth, and the country entered a period of rapid development of heavy industry and large-scale construction of infrastructure, which led to the rapid development of the hoisting industry. The development of a large number of engineering construction projects has increased the demand for hoisting, and a large number of enterprises have entered the hoisting service industry by purchasing crawler cranes and truck cranes. [0003] After 2010, the growth rate of national fixed asset investment slowed down, and my country's hoisting service industry entered a stage of steady development. In 2010, the market size of my country's hoisting service industry was 50.3 billion yuan, and by 2014, its market size had grown to 102.6 billion yuan. It is estimated that by 2019, the ...

Problems solved by technology

[0011] The purpose of the present invention is to provide a large-scale hoisting equipment, the position of the hook bar can be easily and quickly changed, and can be fixed at any position on the slide rail, and a variety of hook-shaped embedded hooks solve the problem of the existing equipment. It is very inconvenient to change the position of the rod, and it is impossible to make small changes in the position of the hook rod on the beam frame, and it cannot be applied to more occasions.
