Performance
Double-beam crane pulley block is the core transmission component of double-beam lifting equipment such as bridge type and gantry type. It is composed of fixed pulley, movable pulley and balancing pulley. It is made of high-strength alloy steel or cast steel to ensure high load capacity (single group can reach 500 tons) and long service life. Its precision-machined rope groove (U-type/V-type) can effectively reduce wire rope wear. With spherical roller bearings or impact-resistant sliding bearings, it can achieve stable and low-noise load lifting and lowering. It is suitable for heavy-load high-frequency scenes such as metallurgy, ports, and wind power.
The pulley block has a modular design, supports quick disassembly maintenance, and can be equipped with an intelligent monitoring system (such as temperature and vibration sensors) to provide real-time feedback of the operating status to the control center. Safety designs such as anti-dropping baffles and balanced tension structures can prevent wire ropes from jumping or unbalanced loading, and improve operation reliability. According to the working conditions, special models such as high temperature resistance, corrosion resistance or explosion-proof can be customized to adapt to different industrial environments.
The double-beam crane pulley block has the core advantages of high efficiency, labor saving and convenient maintenance, which significantly reduces energy consumption and prolongs the life of wire ropes. Its standardized interface is compatible with mainstream crane models and supports non-standard customization. It is a key component to improve the performance and safety of lifting equipment.
APPLICATION
The pulley block of a double-beam crane (such as a bridge crane or a gantry crane) is a core transmission component, and its performance directly affects the lifting efficiency, stability and safety. Since double-beam cranes are usually used in heavy-load and frequent operation occasions (such as metallurgy, ports, workshops, etc.), their pulley blocks need to have high load-bearing, wear-resistant, impact-resistant, and low-friction characteristics.
