[0002] Single-point hoisting refers to a hoisting method in which a load is suspended through a single hoisting point, and is usually used for hoisting light or medium-sized objects. This method is simple and effective, and is suitable for occasions with limited space or where precise positioning is required. Single-point hoisting is common in the construction, manufacturing, and logistics industries, and is operated using equipment such as cranes, slings, or electric hoists. Its advantages lie in being fast and flexible, but special attention should be paid to safety measures when the load is heavy or unstable.
[0003] In traditional single-point hoisting, a hook is used to connect the load to ensure the safe suspension of the load. The sling can be a steel wire rope or a chain, which is responsible for bearing and transmitting the gravity of the load. A crane or a bracket provides a support structure, usually a fixed or mobile hoisting device. An electric hoist or a manual winch is used to lift and lower the load to achieve vertical movement. A control system is used to operate the crane or the electric hoist, which may include a remote control or a button panel. Safety devices such as a loose rope alarm and an overload protection device ensure the safety of the hoisting process.
[0004] However, compared with traditional stages, the technical applications of current stages are more diversified and changeable, and the unity of control, etc. At present, there are only light DMX512 single-point hoists on the market, which have problems such as small load, basically about 20 kilograms, and insufficient control and protection measures, and cannot meet the needs of current stage stage design and creation.
