The hoisting machinery is lifted or lifted by a lifting hook or other pick-up device to move the heavy object. The operation of the hoisting machinery usually involves the processes of lifting, running, lowering and returning to the original position. The hoisting tissue lifts the weight from the picking address through the picking device, shifts the weight through the running, reversing or splaying tissue, and returns to the original position after placing the heavy object at the specified address.
The drive device is used to drive the power plant of the work organization. container spreader Common drive devices include electric drives, internal combustion engine drives, and manual drives. Electric energy is the driving power of cleaning and economy. Electric drive is the primary driving type of modern cranes. Electric cranes are used for rail cranes, elevators and elevators that operate within a limited range. For mobile cranes that can be moved over long distances (such as car cranes, tire cranes and crawler cranes), internal combustion engines are often used. The human drive is suitable for some light and small lifting equipment, and is also used as a temporary power for the assistance, backup drive and accident (or event condition) of certain equipment.
The organization of operations includes: lifting organization, operating organization, luffing organization and rotating organization, which are called the four major organizations of cranes.
(1) The hoisting organization is used to complete the straight lifting of materials. It is not the case that any crane gantry cranes are not short, so it is the most important and fundamental organization of cranes.
(2) The operation organization is the organization that completes the horizontal transfer of materials through the operation of cranes or lifting trolleys. It has the functions of trackless operation and rail operation. According to its driving method, it is divided into two types: self-propelled and traction.
(3) The variable amplitude structure is the unique working organization of the boom crane. The variable amplitude tissue changes the length of the boom and the elevation angle to modify the work fluctuations.
(4) Rotating the tissue is to make the boom move backwards around the straight axis of the crane and transport the material in the annular space. The crane moves through the individual movement of a certain organization or a combination of multiple tissues to reach the intention of transferring the material.
