The container spreader is a large automatic lifting equipment specially used in port terminals, logistics parks and railway freight yards, mainly for the rapid grabbing, lifting, transportation and stacking of standard shipping containers, and is the core supporting equipment of the modern container logistics and transportation system. Adopting a modular high-strength steel structure design, it has large overall bearing capacity and strong wind resistance stability, and can adapt to various standard containers such as 20ft, 40ft and 45ft, covering most sea and land container specifications. Equipped with a fully automatic twist lock system, it can accurately dock with the four-corner lock holes of containers to realize automatic locking and unlocking without manual high-altitude auxiliary operation, completely avoiding high-altitude operation risks and greatly improving container loading and unloading efficiency. It is equipped with intelligent sensing devices and multiple safety protection functions such as anti-mislocking, anti-drop, overload early warning and posture correction, which can monitor the lifting state in real time and effectively prevent safety accidents such as box tilting and falling, ensuring safe and controllable operation. For port open-air working environment, the equipment is strengthened with windproof, rainproof, anti-corrosion and rust-proof treatments, which can adapt to complex outdoor working conditions such as sea wind erosion, alternating high and low temperatures and strong winds, and operate stably all day long. Meanwhile, it has a telescopic adjustment function, which can quickly adapt to containers of different sizes with convenient and efficient switching, and is widely used in port loading and unloading, railway container transportation, yard stacking and freight hub transit scenarios.
