Abstract: Tower crane belongs to tall towers truss structures, whose bucking instability often lead to collapse. Past studies focused on the mast instability under a single load, which doesn’t apply to the actual condition that tower crane working under various loads at the same time. This paper taking into consideration the tower crane lifting weight as well as various loads like the hoist tipping moment, heavy vertical load, wind load, the centrifugal force, rotary load of resistance and horizontal inertia force. Through the eigenvalue bucking and nonlinear bucking analysis, we can get the lifting load when the hoisting is focusing on a maximum working range of the arm of the tower and tower bar force status and the convergence map of stability. This study provides the complete steps of the tower stability design of tower crane, can be used as a guidance or reference for the actual product design.

Abstract: The internet of things is connected to the Internet, through all kinds of sensing device, the RFID technology, video recognition technology, infrared sensing, global positioning system (GPS), according to the need to implement objects connected to the network of the connectivity, exchange of information and communication, in order to realize intelligent identification, location, tracking and monitoring and management of intelligent network system. First this paper introduces the internet of things technology concrete application in the warehouse operation: the RFID technology; management and control technology; sensor technology. Then discusses the internet of things technology development trend in warehouse operation: the application of RFID technology in warehousing will be rapid development; the integrated application of sensing technology; the AGV will be integrated into the warehouse the Internet of things; the storage and the Internet of things will be the trend of the each other.
