Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a protective positioning fence for a crane. Background Art

[0002] Lifting equipment is a common accessory for cranes. Special rigging such as hooks, wire ropes, and chains are commonly used in lifting equipment. Lifting suction cups, clamps, and forks can be used as special lifting equipment on cranes for a long time, or they can be hung on hooks as replaceable auxiliary lifting equipment for temporary use. They are often used in warehouses and yards with multiple types of goods to improve work efficiency. Lifting equipment for grabbing bulk materials is generally a grab with openable and closable jaws, and electromagnetic suction cups can also be used to absorb magnetic materials such as metal chips. Lifting equipment for lifting fluid materials is commonly used in barrels and hanging pots. Molten steel or chemical solutions are usually unloaded by tilting or pulling out the bottom plug, and fluid materials such as concrete are unloaded by opening the bottom door of the hanging pot.

[0003] However, the crane's sling is dangerous in daily use because of its heavy weight and any bumps or collisions may cause serious damage. When an operator or pedestrian collides with it due to negligence, an accident may easily occur. Therefore, warning signs are usually sprayed on the sling to warn irrelevant personnel to stay away. However, during long-term use of the sling, the warning signs on the sling are easily scratched and blurred, affecting the warning effect.

[0004] Therefore, a crane hoist protective positioning fence with high safety, obvious warning and good warning effect is needed. Utility Model Content
