Abstract: High-place operation basket is used to support the operations of decorating outer walls of high-rise buildings. Hanging suspension machine of the basket is a steel structure set up on the top of high building to support overhanging platform and to bear designed load through the steel wire rope. Based on the mechanical analysis of the hanging suspension machine of the basket, the issues on lever balance, rational design of the strength of member bar and safety assessment are studied for a simple model, a compound rods. This kind of popular issues in reality could be good examples for basic education of mechanics and used as project for students' design course to improve their academic abilities like deeper observation, independent thoughtcreation, comprehensive knowledge utilization to ana-lyze and solve practical problems.
