AI Technical Summary

Technical Problem

The current process of hoisting engines for mining excavators presents problems such as high difficulty in engine assembly and low hoisting efficiency. In particular, different specifications of engines require the replacement of auxiliary tools, which leads to a decrease in production efficiency.

Method used

Design a hoisting device for mining engines. It adopts a four-corner hoisting method and uses a combination structure of sliding frame and sliding rod to achieve adjustable width hoisting. The use of limit bolts and chain connection ensures the smooth lifting and precise installation of the engine assembly.

Benefits of technology

This enabled the safe and stable lifting of the engine assembly, avoiding collisions, improving lifting efficiency and applicability, and simplifying the assembly process.
