Load limiters and load moment limiters are collectively referred to as overload protection devices. Overloading is one of the primary causes of crane accidents. In mild cases, overloading can damage crane components, causing motor overload and structural deformation. In severe cases, it can result in broken beams, tower collapse, arm fractures, or even complete machine […]

The structure of the short-stroke block brake is shown in Figure 1-17. When the electric motor is powered on, the electromagnet coil connected in parallel with the motor winding is also energized. This generates an attractive force in the stationary core (9), which pulls the moving core (8). Consequently, the push rod (7) is pushed […]

1. Classification by Length Ball mills can be classified based on the ratio of their length to diameter. This classification affects their grinding efficiency, usage, and application in various industries. (1) Short Ball Mill A ball mill is considered short if its length-to-diameter ratio is less than 2. It is commonly referred to simply as […]

As a type of lifting and transportation machinery, large tower cranes are prone to rust and corrosion due to various unresolved issues. The steel structures of large tower cranes are particularly susceptible to rusting when exposed to air for extended periods without adequate protective measures. This corrosion occurs when the steel structure reacts chemically with […]
