Lifting machinery is typically large in size and has complex mechanisms, capable of performing both vertical lifting and horizontal movement. For instance, a bridge crane can perform three motions: hoisting, trolley movement, and cart running. A gantry crane, on the other hand, can handle four movements: lifting, luffing, slewing, and cart running. During operation, multiple directional movements often occur simultaneously, making it technically challenging.
The loads handled by lifting equipment vary significantly in weight and type. Some objects can weigh hundreds or even thousands of tons, while others are long and irregular in shape. Additionally, there are items such as loose particles, molten materials, flammable, and explosive substances, all of which make the lifting process more complicated and dangerous.
Most lifting machines operate in large spaces. Some move along rails and wheels (like tower cranes or bridge cranes), while others use tires or tracks (such as mobile cranes or crawler cranes). Some even travel along wire ropes, like aerial ropeways for passengers or freight. Due to their wide range of movement, any accident involving these machines can have serious consequences.
Some cranes are designed to carry people directly, such as elevators or suspended platforms. In these cases, the reliability of the equipment is crucial, as it directly affects human safety.
Lifting machinery is often exposed to the environment, with many moving parts that come into direct contact with workers, such as hooks and wire ropes. This exposure increases the number of potential hazards and risks during operation.
The working environments where lifting machinery is used are also highly complex. From large steel plants to modern ports, construction sites, railway stations, and tourist areas, lifting equipment is commonly in use. These locations often involve high temperatures, pressure, flammable materials, electrical lines, and strong magnetic fields, posing threats to both workers and the machinery itself.
Operating lifting machinery usually requires coordination among multiple personnel. A single task may involve operators such as signalers, riggers, and drivers, who must work together, communicate effectively, and remain alert. The need for close teamwork makes the operation more demanding and increases the importance of emergency response skills.
These characteristics of lifting machinery highlight its critical relationship with workplace safety. Any oversight in design, manufacturing, installation, usage, or maintenance can lead to serious accidents, causing injuries or even fatalities, as well as significant economic losses. Therefore, strict safety measures and continuous monitoring are essential to ensure safe and efficient operations.
Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
