Jib cranes are essential tools for lifting and moving heavy objects, and their widespread use across various industries makes it crucial to understand the basic safety guidelines to operate them effectively and safely. Although most companies provide a safety manual during installation, here's a concise guide to help you adhere to these essential rules and prevent accidents that could endanger lives. First and foremost, always have professionals handle the installation of your jib cranes. This ensures that the equipment is securely mounted, with a solid foundation capable of supporting the load. It also guarantees that the crane is thoroughly tested and certified before being put into use. Before using the crane regularly, inspect it for common issues like debris on the runway, structural damage, loose or missing bolts, and cracked welds. Additionally, confirm that the jib arm moves smoothly and is correctly aligned over the load to maintain stability during lifting. To prevent accidents, ensure that the beam trolley doesn't collide with the runway end stops, as this can cause the load to swing unpredictably, increasing its radial span and disrupting balance. Conduct a trial lift to assess stability, ensuring that the slewing arm moves unobstructed. Always perform all movements slowly and steadily to minimize the risk of swinging. Avoid dragging loads along the ground or placing ladders against the jib arm, as both practices can lead to instability. During operation, never let anyone walk beneath the loaded crane. Prioritizing safety, consider having your jib cranes professionally inspected annually by qualified personnel, as mandated by UK regulations.

The working process of a diesel engine is actually the same as that of a gasoline engine, and each working cycle also goes through four strokes: air intake, compression, work and exhaust.

The diesel engine sucks pure air in the intake stroke. When the compression stroke is nearing the end, the diesel fuel is increased to more than 10MPa by the fuel injection pump, and is injected into the cylinder through the fuel injector, and mixed with the compressed high-temperature air in a very short time to form a combustible mixture. Due to the high compression ratio of the diesel engine (generally 16-22), the air pressure in the cylinder can reach 3.5-4.5MPa at the end of compression, and the temperature is as high as 750-1000K (while the mixture pressure of the gasoline engine at this time will be 0.6-1.2MPa, and the temperature will reach 600-700K), which greatly exceeds the autoignition temperature of diesel. Therefore, after the diesel fuel is injected into the cylinder, it mixes with the air in a very short time and immediately ignites and burns on its own. The air pressure in the cylinder rises sharply to 6-9MPa, and the temperature also rises to 2000-2500K. Driven by high-pressure gas, the piston moves downward and drives the crankshaft to rotate to do work, and the exhaust gas is also discharged into the atmosphere through the exhaust pipe.
