Recently, Qianhao Magnetic Electric's independently developed next-generation electro-permanent lifting system completed acceptance testing and was officially put into operation at a major domestic port. The system consists of five high-precision electro-permanent magnet units, seamlessly integrated with an intelligent lifting beam via flexible soft connections. It effectively addresses the longstanding challenges of unstable adhesion and cumbersome operations typically encountered with conventional lifting equipment in complex handling scenarios, providing a safe, efficient, and versatile solution for industries such as steel logistics and heavy-load handling.
Flexible Design: 100% Adhesive Fit, Adaptable to Multi-Shape Workpieces
The electric permanent magnet lifting device undergoing this acceptance test features a soft-connect structure, utilizing an elastic chain mechanism to automatically adjust to varying suction heights. This design ensures 100% tight contact—even when handling steel plates, billets, or round tubes with uneven surfaces—thereby guaranteeing uniform magnetic force distribution and eliminating any risk of adsorption failure or detachment. This innovative design breaks away from the stringent flatness requirements traditionally imposed by rigid lifting tools, significantly enhancing the compatibility and stability of lifting operations.
Multi-purpose in one device: Covers multiple scenarios, freeing up labor costs.
In the dock steel plate unloading scenario, Qianhao's electro-permanent magnetic lifter demonstrates its advantages in full-process automation:
- Operation Simplified: With just one-button control—activating "magnetization/demagnetization"—from either the crane operator’s cabin or a ground-based remote, you can effortlessly complete the process of lifting and releasing steel plates, eliminating the need for manual pre-positioning of steel plate clamps or laying down wooden pallets.
- Multi-configuration lifting: Supports simultaneous lifting of various materials, including multi-layer steel plates, single-layer separation, thin sheets, and slabs. The magnetic strength can be precisely adjusted to prevent deformation of thin sheets caused by excessive magnetism—or slipping due to insufficient magnetic force.
- Safety Upgrade: Completely eliminate safety risks caused by human error or tool aging associated with traditional lifting equipment. Loading and unloading personnel no longer need to work in close proximity to heavy objects, boosting worker safety by more than 100%.
