This book describes the current situation and development of hoisting machinery at home and abroad; the basics of truck cranes, crawler cranes construction and maintenance necessary; focuses on the structure and maintenance of truck cranes, crawler cranes, tire cranes; truck crane and Crane fault diagnosis and troubleshooting. Appendix gives a comparison of domestic and foreign oils and fats; regulations of Japanese cranes; ten taboos for maintenance of construction machinery; and “Regulations for the Supervision of Special Equipment Safety in China”.
This book is widely used for the use, maintenance, management, ordering personnel of hoisting machinery equipment. It can also be used as a reference for engineering machinery technicians, or as a professional training material.

Foreword Since the 21st century, the growing trend of economic globalization and the rapid development of modern science and technology have effectively promoted the development of China's logistics industry and logistics technology. China has become one of the fastest growing countries in the world economy. The logistics industry will then become an important industry and new economic growth point for China's economic development in the 21st century.
Engineering machinery (car cranes, tire cranes, crawler cranes, etc.) in logistics machinery and equipment are infrastructure projects (industrial and civil construction, water conservancy construction, port construction, defense engineering, etc.), and the company’s products are effectively transferred from the supply to the need Throughout the entire process, equipment used for lifting, transportation, handling, processing, distribution, warehousing and packaging work. The production volume of China's automobile cranes, tire cranes and crawler cranes ranks among the top in the world.
Most of the construction cranes work under conditions of poor construction conditions and poor conditions. Failure of the equipment is unavoidable. This requires operators and maintenance personnel to quickly and accurately determine the causes and locations of failures based on fault phenomena. , and can eliminate the fault as soon as possible. In order to effectively ensure the utilization ratio of the construction cranes, and to achieve fewer failures in use, it is necessary to do a good job of daily maintenance work and constantly learn to master the methods of fault diagnosis and elimination of construction cranes.
This book refers to domestic and foreign engineering crane publications and online publication of information, combined with examples to introduce the structure of the crane engineering and maintenance and fault diagnosis and troubleshooting methods. It can provide basic knowledge and working methods for equipment management personnel, provide maintenance personnel with effective maintenance measures, provide reference equipment for ordering equipment, provide basis for designers to improve construction machinery design, and can also be used as professional training materials.
The book is divided into 6 chapters. The division of work is as follows: Chapter 1 Ning Guoping, Chapter 2 Xu You, Chapters 3, 5, and 6 Wang Suguang, Wang Fengxi, Wang Yi, Chapter 4 Wei Caizhi and Liu Jun. The book is edited by Zeng Xiangdong and deputy editors are Jiang Shizhong, Guo Guoying, Liang Jian, and Wang Fengxi.

A luffing tower crane is a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius of a luffing crane is highly reduced in comparison to standard tower crane types. The luffing jib tower crane also has a higher lifting capacity because the weight is transferred from the crane`s jib much more effectively.
