How to Choose Magnetic Lifter: Types and Buying Guide
Contents
Choosing a suitable magnetic lifter is crucial for optimizing work efficiency and ensuring safety. As a professional lifting magnetic chuck manufacturer, Guang Dar will guide you through the steps and considerations when selecting a magnetic lifter, shedding light on various types and factors to make an informed decision.
What is a Magnetic Lifter?
A Magnetic lifter, also known as a lifting magnetic chuck or lifting magnet, is a material handling equipment designed for gripping, lifting, conveying, and releasing materials using magnetic force. Unlike traditional work-holding systems with jaws or claws, a magnetic lifting chuck is a box-like structure that adds and removes a magnetic field to a workpiece. It decreases the need for hooks, slings, jaws, or other traditional lifting attachments. Magnetic lifters are commonly used in various industries, such as manufacturing, construction, and metalworking, for lifting steel plates, bars, or other ferrous materials. They provide a safer and more efficient alternative to traditional lifting methods.
Types of Magnetic Lifters
Permanent Magnetic Lifters:
A permanent magnetic lifter is a lifting device that utilizes permanent magnets to lift and transport ferrous materials. Their permanent magnets are often made of neodymium or ferrite, capable of attracting and holding onto ferrous objects. Unlike electromagnetic lifters that require an electric current to create a magnetic field, permanent magnetic lifters have a fixed magnetic field that is always present. These units are safer since they don't require electricity, reducing concerns about power surges or outages. They are compact and easy to move from different areas. Besides, they are particularly useful in environments where a continuous power source may be impractical or where simplicity and reliability are essential.
Electromagnet Lifters:
It primarily consists of an electromagnet. An electromagnet is a specific magnet formed by running an electric current through a coiled wire. The electromagnet lifter lifts steel objects when the current is activated and lowers them when the current is deactivated. However, it relies on an electrical current for operation. Generally operated with DC power, it needs a chuck controller. Some, like Guangdar's battery-type magnetic lifter, are battery-operated. It has the control panel integrated into the lifting magnet, reducing the need for an additional check controller.
▲Guang Dar's battery-operated magnetic lifter (GM type) is made explicitly for carrying common steel molds. It has a built-in battery and alarm system that prevents any trouble caused by the broken power supply and is equipped with electricity charging equipment. The lifter's high magnetic force easily carries a mass of small parts or scrap iron. It has no limitation by a power supply line and offers a large working space.
How to Choose Magnetic Lifter: 8 Factors to Consider When Purchasing
1. Understand Application Requirements:
Before purchasing a magnetic lifter, it is crucial to have a thorough understanding of the application requirements. Start by identifying the type, size, shape, and material of the workpieces for which the lifter will be used. This will help determine the appropriate magnetic lifting capacity needed for the lifter.
In addition to the workpiece specifications, we also need to consider the machining process and type of machine tool. The type of machining process can affect the stability of the workpiece, which in turn impacts the effectiveness of the magnetic lifter. Furthermore, the kind of machine tool used can influence the weight and shape of the workpiece, which must be considered when selecting the appropriate magnetic lifter.
2. Lifting Capacity and Height Requirements:
Evaluate the maximum load you need to lift to determine the appropriate lifting capacity of the magnetic lifter. Additionally, consider the required lifting height and transportation distance. These factors will help you choose the suitable magnetic lifter to meet your needs.
3. Work Environment Conditions:
It is important to consider the temperature and humidity levels of the work environment when purchasing a magnetic lifter, as these conditions can significantly affect the lifter's performance. Besides, the materials used in the lifter must be resistant to moisture, corrosion, and other adverse factors that may be present in the workplace.
4. Rated Load Maximum Value:
Consider the rated load maximum value. This value represents the maximum weight that the lifter is capable of lifting. However, it is not enough to look at this value when purchasing. It is recommended that the required suction force be specified to ensure that the lifter can safely and effectively lift the intended workpiece.
In addition to the required suction force, it is important to consider the surface condition and smoothness of the workpiece. If the workpiece has a rough or uneven surface, increasing the required suction force may be necessary to ensure a secure hold.
For safety reasons, it is recommended that the actual breakaway force of the lifter should be at least 3.5 times greater than the maximum lift ratings. This ensures the lifter can safely release the workpiece during a power failure or unexpected event.
5. Control and Operation Method:
Considering the control and operation method when purchasing a magnetic lifter is important. You should choose a control method that suits your specific needs. There are two main control methods available - manual and remote-controlled.
Manual control is ideal for small-scale operations where a single operator can easily control the magnet. The operator can use a lever or knob to activate or deactivate the magnet as needed. This method is simple and cost-effective, making it a good option for those on a budget.
Remote-controlled lifting magnets, on the other hand, are more advanced and allow for greater precision and control. They are ideal for more extensive operations where multiple operators may need to remotely control the magnet. They can be operated using a remote or computer interface, allowing greater flexibility and control.
The control method you choose will depend on the specific needs of your operation. Consider factors such as the size of the materials being lifted, the number of operators, and your budget when deciding.
6. Safety and Regulatory Compliance:
To guarantee the safety of your workers and equipment, it is advisable to prioritize safety and regulatory compliance when purchasing a magnetic lifter. You can achieve this by selecting a lifter that complies with local regulations and standards. This involves checking for any certifications or approvals required in your area.
Also, adhering to safety guidelines when using the lifter is crucial. This includes proper training for all operators, regular maintenance and inspections, and following all recommended usage instructions. To ensure a safe working environment, taking certain precautions that minimize the risk of accidents is important.
7. Cost and Budget:
Ensuring you find a magnetic lifter that meets your needs and budget requires a thorough and thoughtful approach. Carefully consider your cost and budget requirements. Start by defining your budget range, considering the features and capabilities that are most important to you. Once you have a clear budget, you can compare various brands and models to find the best cost-effective solution. Look for reviews and ratings from other customers to determine the reliability and performance of each option. Moreover, think about any additional costs associated with your purchase, such as shipping fees or installation costs.
8. Brand and Supplier Reputation:
Choose a supplier and manufacturer with a solid reputation in the industry. This will ensure you receive a high-quality product that meets your needs and performs reliably over time.
One such reputable supplier and manufacturer is Guang Dar, which has a proven track record of producing top-notch magnetic lifters that are both durable and efficient. Invest wisely in a product that will serve you for years by choosing a trusted brand like Guang Dar.
