Why choose HVR MAG electro permanent lifting magnets?
HVR MAG focuses on the research and development, production, and sales of electro permanent magnet products. With 20 years of experience in the electro permanent magnet industry, we can provide customized services according to the customer’s working conditions and provide one-stop electro permanent lifting magnet solutions for enterprises.
What are the advantages of HVR MAG electro permanent lifting magnets?
1、Unique dual magnetic source technology and modular design
The internal structure of the electro-permanent magnet is unique, using two kinds of permanent magnets as the magnetic source; at the same time, the electro-permanent magnets from HVR Magnetics all adopt modular design, with stronger applicability and versatility.
2、Safety
HVR MAG lifting magnet attracts the workpiece without electric power. So it avoids the risk of losing the magnetic force when the electromagnet system is suddenly powered off or the connection cable is damaged. The electro permanent lifting magnet can produce a strong magnetic force of 16kg/cm2 (theoretically ), which does not decay with time and has great safety. However, the electromagnet only has a limited magnetization time after a power outage, and a long power outage will easily cause accidents. The electro permanent lifting magnet lifter from HVR Magnetics can be attached with the function of landing detection. The demagnetization operation will be effective only after the load is completely landed, eliminating the danger caused by misoperation.
3、Energy saving, economic and environmental protection
The electro permanent magnet system only uses electric energy within 0.1~2 seconds of magnetization and demagnetization. That’s how it saves more than 95% of power consumption compared with electromagnet. The control system is simple, and both the body and control system is lightweight. So it can reduce the load of lifting equipment and improve the lifting capacity as well as the usage rate of the equipment. While the electromagnet needs a battery when the power is out to keep the magnet, the electro permanent magnet is more environmentally friendly.
4、Practical and efficient
Electro permanent lifting magnet system has no moving parts inside (permanent lifting magnet has moving parts). That’s why it is reliable and durable, practical and strong. Electric control operations only have charges and demagnetization buttons, which is a quite simple and convenient operation. The depth of permeability of the electro-permanent magnet is adjustable. It ensures that only a single steel plate is lifted each time and never sticks to the steel plate. The magnetizing and demagnetizing time is only 0.12 seconds. It greatly improves the lifting efficiency of a single steel plate.
After demagnetization, the residual magnetism on the surface of the electro-permanent magnet lifter is almost zero, even small magnetic particles will not be adsorbed on the surface of the magnetic pole, which will not scratch the absorbed object and will not cause residual magnetism hazard to the absorbed object.
how many types of excavator attachment are there?
types of excavator attachments
There is a wide variety of excavator attachments available, each designed to serve specific purposes and cater to different applications. While the range of attachments is extensive, here are some common types of excavator attachments:
Buckets: Various types of buckets are used for digging, grading, and material handling. These include general-purpose buckets, trenching buckets, rock buckets, and clamshell buckets.
Hydraulic Hammers/Breakers: Hydraulic hammers or breakers are used for breaking and demolishing hard materials like concrete, rocks, and asphalt.
Augers: Auger attachments are used for drilling holes in the ground for applications such as fence post installation, tree planting, and soil sampling.
Grapples: Grapple attachments feature gripping jaws and are used for handling and moving materials such as logs, rocks, and debris.
Rippers: Rippers are used for breaking up hard soil, ice, or compacted materials, typically in preparation for excavation or grading.
Demolition Tools: These attachments, such as pulverizers, shears, and crushers, are specifically designed for demolition and recycling tasks.
Tilt Rotators: Tilt rotators provide additional rotation and tilting capabilities to the excavator’s bucket or attachment, allowing for enhanced precision and flexibility.
Thumbs: Thumbs are used to enhance the excavator’s grasping capabilities, enabling it to handle objects like tree stumps, rocks, or irregularly shaped materials.
Vibratory Plate Compactors: These attachments are used for compacting soil, gravel, or other loose materials to achieve a solid and level surface.
Graders and Levelers: Attachments such as grading blades and leveling buckets are used for precision grading, shaping, and leveling of surfaces.
Mulchers: Mulcher attachments are used for land clearing and vegetation management by cutting and mulching trees, bushes, and other vegetation.
These are just a few examples of the diverse range of excavator attachments available. The selection of attachments depends on the specific tasks and requirements of the project at hand.
