Q:The electromagnetic Jack does not seem to use the principle of electromagnetic induction.

Magnetic jack for permanent magnet lifting, lifting electromagnet and permanent magnet electric jack. The permanent magnet generally require manual rotating wrench demagnetization operation, high labor intensity, but also by the permanent magnet structure prevents electromagnetic permanent magnet to large size. Lifting electromagnet is magnetic in the work of the need to maintain the Everfount has power, high power consumption, and in the case of external power or coil system failure, will cause the workpiece to drop electromagnet magnetic loss, using low security. The electronic permanent magnet technology overcomes the shortcomings of the above mentioned permanent magnet and electromagnetic products, and sets up the advantages of the two - - using permanent magnetic force as the working suction, and controlling the charging and demagnetization with the power supply. The electric permanent magnet with high performance permanent magnet material inside, and equipped with the excitation coil. When the moment into the positive pulse, the permanent magnetic constant external display for magnetic moment; to reverse pulse power source, the permanent magnetic force in the magnets inside the closed, do not show magnetic (demagnetization), truly achieve the safe use, convenient operation etc..

Q:Rack type lifting machine, rack press, rack lifting machine

Rack type lifting machine is mainly used for railway track laying and maintenance. The utility model is widely used for lifting and supporting the installation of various heavy objects and equipment in industrial and mining enterprises, as well as bridge erection. Rack Jack (also known as lifting machine) is also called manual lifting machine.

Q:The principle of an air compressor for connecting two pistons

There are several forms of contact, often in several forms: piston compressors, the most common and the most frequently used type of reciprocating compressor, whose pistons direct contact with gases. Seal the compressed gas by the piston ring. In pneumatic transmission, a displacement piston compressor is usually used. Two typical structures are introduced here to help understand the working principle of air compressors. Figure 3.33 (animation) and figure 3.34 (animation) respectively gives the working principle of vertical and horizontal air compressor. The center line of the vertical air compressor is perpendicular to the ground, and the center line of the cylinder of the horizontal air compressor is parallel to the ground. The rotational motion of a prime mover (an electric motor or an internal-combustion engine) is converted into reciprocating rectilinear motion of a piston by a crank link mechanism.

Q:What's the difference between a horizontal jack and a vertical jack?

Horizontal jack is used as a rigid top lift working device, lifting heavy light small lifting equipment in the small tour through the bracket at the top. It is a kind of widely used in heavy vehicles or mobile devices supporting equipment weight, adjust the equipment level of an important hydraulic components, it is mainly used for industrial, transportation and other departments as vehicle repair and other lifting and supporting work.

Q:What are the protective measures against crane injuries?

Avoid travel with load, short distance travel with load load can allow the weight of 70% members from the ground using 50cm.Two crane lifting reasonable load distribution, unified command and close coordination.The sling should be calculated and the binding method is reliable. Lifting tools are regularly checked.The center of gravity and the weight lifting point should be in the same vertical line, hanging point should be in the center of gravity above.The commander must be certified, in close coordination with the crane driver.It is prohibited for lifting heavy objects long time hanging in the air.To check the ring hook, hook ring welding is prohibited.

Q:I want to know what the principle of magnetic suspension is. Why does it make magnetism disappear?! What is the structure like?!

The working principle of the magnetic suspension is made by using the electromagnetic induction principle of Faraday. The internal use of the high performance permanent magnetic materials of neodymium borax, can produce a strong suction in the magnetic circuit, the magnetic field lines so that the jack handle turn at work or in a closed state; without external power supply, is a safe and energy saving, high efficiency of new lifting tools.

Q:What are the points for attention in the course of transportation of double beam cranes?

Component preparation, component preparation, including component counting, inspection and appearance modification, etc..(1) counting the components, including the type and quantity of the components, checking the order of the components according to the lifting sequence of the components, and determining the sequence of the loading of the components.(2) inspection component. Including size, geometry, the placement of parts and rings, and the stability of the location of the installation hole and the hole through the hole and so on.(3) check the weld seam of the steel structure. Including the weld size, appearance and connections whether the design and specifications meet the requirements, such as beyond the allowable error, should be taken effective measures to deal with.(4) appearance inspection and modification of components. Found defects and damage, such as cracks, pits, broken edge, weld length, height is not enough, weld ash or porosity, should be modified and after welding, to transport and use.

Q:What are the characteristics of HHXG type inverted chain chain electric hoist?

Structure of party workers to operate a variety of mechanical lifting tools related products such as: black bear small diamond chain electric hoist, hoist, hydraulic jack, three spring balancer, Longsheng plate clamp, dragon masunaga magnet, horse sand hydraulic jack, straight weight shifting device, permanent magnet lifter, ultra thin hydraulic cylinder, mini chainhoists.

Q:Do hardware or plastic factories have no need for cutting tools?

Hardware parts pointing on more widely, such as: screws, panels, hoses and other metal accessories.

Q:What elements should I take into account when purchasing a car?

As the saying goes Forewarned is forearmed. Adequate preparatory work is essential in deciding to buy a lorry to enter the road freight transportation industry.
