Custom Lifting Beams
Lifting beams and magnetic lifting tools are commonly used specialized auxiliary tools in lifting operations, widely applied in various lifting scenarios such as steel mills, machine shops, ports, and storage yards. Lifting beams, as specialized horizontal beam lifting tools, are primarily used for the stable lifting of loads, ensuring lifting safety. Magnetic lifting tools rely on strong magnetic fields to attract and lift heavy metal objects. They come in two types: permanent magnet and electromagnetic. They are easy to operate and highly adaptable. Together, they provide safe and efficient solutions for lifting operations of different scenarios and types of materials.
Product Description
This section summarizes two common lifting tools: lifting beams (including load-bearing beams and connecting rigging) and magnetic lifting tools (including permanent magnet and electromagnetic lifting tools). Both comply with relevant industry standards, and their structural design is tailored to the needs of lifting operations, adapting to different weights and types of lifting scenarios. They are indispensable auxiliary equipment in lifting operations.
Lifting Beam Core Structure and Principle
The lifting beam is a specialized horizontal beam lifting device for hoisting objects. It mainly consists of a main load-bearing beam and connecting rigging. The main load-bearing beam is the core load-bearing component, with a safety factor of 4. It has lifting rings at the top for direct connection to the overhead crane hook, and lifting lugs at both ends to connect the load-bearing beam to the object being lifted (such as a ballast bar). By distributing the load, it achieves stable and safe hoisting of the object, conforming to JB/T5000.1-5000.15-1998 General Technical Conditions for Heavy Machinery.
Magnetic Lifting Device Core Structure and Principle
Utilizing a strong magnetic field as the core attraction force, it employs high-performance neodymium iron boron magnets as the magnetic source, combined with steel to form a strong magnetic system. Depending on the magnetic source, it is divided into permanent magnet lifting devices and electromagnetic lifting devices. Permanent magnet lifting devices rely on persistent magnetic force to attract heavy objects and do not require an external power source. Electromagnetic lifting devices generate a magnetic field through electromagnetic coils, requiring an external power source. The magnetic force can be adjusted to achieve rapid attraction and release of heavy objects.
Applicable Scenarios
Lifting beams are suitable for the stable lifting of various objects, especially suitable for scenarios requiring distributed loads and avoiding uneven stress on the object. Magnetic lifting devices are widely used in steel mills, machine shops, and other occasions requiring the lifting of metal materials. Permanent magnet lifting devices are suitable for scenarios involving frequent movement of heavy metal objects, while electromagnetic lifting devices are suitable for lifting metal materials of different weights and shapes.
Core Functions
Lifting beams ensure the safe lifting of objects, with a flexible structure and convenient use, ensuring a stable and sway-free lifting process. Magnetic lifting devices achieve the attraction and lifting of heavy metal objects, with simple operation and effective reduction of labor costs. Electromagnetic lifting devices allow for adjustable magnetic force and rapid release of heavy objects, improving work efficiency.
