Make analysis and theoretical guide for the hydraulic hoister which provides design methods for the development of similar products. Hoister is one of the main equipment in drilling construction tripping， casing and handling accidents in the hole. Hydraulic hoister has the pact structure， smooth transmission， large adjustment range， manipulating simple and easy to install. It can be used independently， and is a very worthwhile product to development. With the rapid development of many kinds of enterprise in our country， many requests are set for the security， the convenience flexibility and the working efficiency of the correlation equipment. To meet the needs of modern construction and the updating of metallurgy， mining， light industry and other sectors lifting equipment， design the freedom hookdropping hoister is going necessarily. The hoister used three plaary gear for driving， the driving volume of plaary gear is small， which can meet the structural requirements of hoister. Meanwhile plaary gear has high driving efficiency， bearing capability is great， smooth， three level plaary gear is used to increase the transmission ratio， so as to achieve the design requireme
