Technical details and manufacturing context for Lifting Frame

Definition
The Lifting Frame is a critical structural component of a Container Handler, designed to withstand the heavy loads and stresses involved in lifting and moving shipping containers. It serves as the primary framework that connects the lifting mechanisms (such as spreaders or hooks) to the main body of the handler, ensuring stability, proper load distribution, and safe operation during container handling tasks. Constructed from high-strength steel, the frame is engineered to meet rigorous industrial demands. Its design incorporates a rated lifting capacity that matches the container handler spreader capacity, typically ranging from 10 to 70 tonnes, in accordance with ISO 1496-1. The frame dimensions vary to fit container widths and handler spreaders: width ranges from 1200 to 2500 mm, length from 3000 to 6000 mm, and height from 300 to 800 mm, depending on container size and lifting mechanism. The material grade, such as Q345B to Q460C per GB/T 1591, provides yield strength of 345–460 MPa and tensile strength of 470–640 MPa. The frame weight typically ranges from 2 to 8 tonnes, affecting total machine weight and stability. Operating temperature range is -40 to 85°C, beyond which steel properties degrade. Surface treatment includes blast cleaning to Sa2.5 per ISO 8501-1, followed by paint thickness of 80–120 μm per ISO 12944 for corrosion protection. Weld quality must meet 100% full penetration welds with no cracks, per ISO 5817. These specifications serve as reference ranges; actual values must be confirmed with the legal manufacturer or supplier for specific models and applications.
Working Principle
The Lifting Frame functions as a rigid structural interface. It transfers the lifting force from the handler's hydraulic or mechanical systems through its robust construction to the container attachment points. Its design ensures that loads are evenly distributed to prevent twisting or uneven stress, maintaining the container's alignment and the handler's balance during lifting, transport, and placement operations. The frame's geometry and material properties are selected to provide sufficient stiffness and strength to handle dynamic loads and fatigue over the equipment's service life. Proper attachment and alignment are critical for safe operation; any deformation or damage to the frame can compromise load distribution and lead to operational hazards. Regular inspection for cracks, deformation, and corrosion is essential to maintain structural integrity.
