Crane refers to a multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead crane, aerial crane, and crane. This article will take a look at how much do you know about cranes? 1. According to the nature of lifting, it is divided into mobile crane, tower crane and mast crane. 2. According to the driving mode, one type is centralized drive, that is, a long drive shaft is used to drive the driving wheels on both sides; the other type is separate drive, that is, the driving wheels on both sides are driven by an electric motor. Medium and small bridge cranes mostly use the 'three-in-one' driving method that combines brakes, reducers and motors. Ordinary bridge cranes with large lifting weights often use universal couplings for easy installation and adjustment. . 3. According to the structure, the cranes are mainly divided into light and small lifting equipment, bridge type (bridge type, construction hoist
), boom type (self-propelled, tower, portal type, railway type, pontoon type, mast type crane) ), cable type. Fourth, use and maintenance 1. Before leaving the factory for lifting and hoisting equipment, it is necessary to make an identity record. Safety inspection and maintenance before equipment installation: check the integrity of the performance of the main mechanisms of the equipment, check the visible defects of the main steel structure and joints and their pins and bolts, check the anti-corrosion condition of the equipment surface, make records, and issue installation opinions. 2. Hoisting equipment is maintained by dedicated personnel. After the equipment is delivered for use, the daily maintenance shall be the responsibility of the equipment operator or the full-time personnel of the user unit, and the installation and maintenance unit shall have the responsibility of supervising and inspecting the contents of the daily maintenance. The main content of daily maintenance is summarized as 'cross operation method': cleaning, tightening, lubrication, adjustment, and corrosion protection. 10-30 minutes before and at the end of the shift every day, inspect all parts and parts of the equipment to see if they are normal, add oil and lubricate according to the regulations, pay attention to whether the sound of the machine is normal, do a good job of cleaning and handover work, so that the appearance of the equipment is neat and running For the purpose, daily maintenance records and shift shift records should be made into fixed forms and managed as files. 3. Regular professional physical examinations are required for lifting and hoisting equipment. Regular inspection and maintenance during the use of the equipment: several maintenance and repairs to the mechanical equipment within the specified time, focusing on cleaning, lubrication, adjustment, dismantling, and overhaul. It is usually done by maintenance personnel and operators together. The above is the introduction of crane knowledge, if necessary, please contact Hoisting Machinery Equipment Co., Ltd.!
