The telescopic lifting beam is another innovative lifting device specifically designed and manufactured by Hugang after investigating the operational requirements at major domestic ports and steel plants for loading and unloading steel plates. When purchasing a crane for steel plate handling, users must select an appropriate lifting beam to match it. The beam can be telescopically adjusted between 13m and 18m, enabling the handling of steel plates up to 22m in length. Additionally, the electromagnetic modules on the beam automatically adjust their positions based on the telescopic length. It features notable characteristics such as safety, high performance, high efficiency, and ease of maintenance.
The spreader is made of high-strength alloy steel or stainless steel, offering exceptional tensile strength and durability to meet the demands of heavy-load lifting. The surface undergoes special anti-corrosion treatment, providing resistance to corrosion and rust, ensuring long-term use in various environments, particularly in seaports or outdoor settings.
The telescopic spreader is equipped with a safety locking mechanism to ensure that after length adjustment, the boom or beam remains securely locked, preventing accidental sliding or retraction during lifting operations, thereby guaranteeing safety. It also includes an overload protection device that triggers an alarm or halts operation when the load exceeds safe limits, preventing damage to both equipment and items.
The device allows for length adjustment via manual, hydraulic, or electric methods, adapting to diverse operational needs. This is especially beneficial in scenarios requiring frequent changes in lifting length, significantly enhancing operational efficiency. Its lightweight structural design and user-friendly operation enable efficient performance even in confined spaces or complex working environments.
