Construction hoists are widely used in modern construction as vertical transportation tools,the advan-tages of the two transmission gear tooth strip construction hoists are more prominent,but its braking performance requirements are higher.It analyzes and conducts research starting from the braking performance of construction hoists.By analyzing the driving device model and numerical calculation,the minimum braking torque of a single braking component is obtained.Then,by calculating the braking torque,a prototype is designed and suitable brake pads are selected for prototype testing and verification.It is demonstrated that the selected brake pads meet the brak-ing performance requirements and can achieve reliable and stable braking of the construction hoists.
