What are the lifting equipment used to lift steel plates?

Special spreader for lifting steel plates Common wire ropes, hooks, steel plate wrenches, vacuum suction cups, permanent magnet chucks, electric permanent magnet chucks on the market. What spreader is used for what occasion, which can be divided into the following four situations:

Choose this one for your own use or when you need to hang steel plates temporarily:

Choose wire rope and hook, steel plate wrench, these are standard parts, it is more convenient to buy, and it is also very cheap. It is suitable for temporary needs, or the needs of small manufacturers.

When the workpiece without contamination is sucked on the smooth contact surface, the spreader is selected

Hanging stainless steel plate, as well as flat steel plate, the surface is clean and pollution-free, when the vacuum suction cup is selected, the vacuum suction cup principle first connects the vacuum suction cup with the vacuum equipment (such as vacuum generator, etc.) through the pipe, and then contacts with the object to be lifted, and starts the vacuum equipment suction, so that the negative air pressure is generated in the suction cup, so that the object to be lifted is sucked firmly, and the object to be lifted can be started to be moved. When the object to be lifted is transported to the destination, smoothly inflate into the vacuum suction cup, make the vacuum suction cup change from negative air pressure to zero air pressure or slightly positive air pressure, and the vacuum suction cup is separated from the object to be lifted, thereby completed the task of lifting and carrying heavy objects.

Vacuum suction cups. The steel plate lifting frequency is high, the specifications are many, and the weight is large

Like steel plate factories and shipyards, these steel plates are frequently handled and have high lifting requirements, and the safety needs to be guaranteed, so they choose electric permanent magnet chucks and electric permanent magnet steel plate spreaders, and Qianhao uses electric energy to control the magnetic field line direction of the magnetic field of permanent magnet materials, so that it can complete the action of adsorption steel plate and unloading plate. This spreader does not need electrical energy, and does not generate heat, no noise, no energy consumption, and the high-strength suction force tightly adsorbs the steel plate. It can not only reduce the labor intensity of loading and unloading workers, greatly improve production efficiency, and low energy consumption, and is an indispensable lifting tool for lifting magnetic materials such as steel in metallurgy, mining, machinery, shipbuilding, transportation and other industries.

Electric permanent magnet spreader.

Permanent magnet chucks can be selected for handling magnetic workpieces from small steel plates

Permanent magnet chucks are often used in mechanical factories, mold factories, and other machining fields widely used in magnetic fixtures, by hand pulling the suction cup handle to rotate, so as to change the magnetic system of NdFeB inside the suction cup, to achieve the suction or release of the processed workpiece. When handling small steel plate magnetic workpieces, you can choose permanent magnetic chuck, which will have greater advantages than electric permanent magnet chuck spreaders**.

The spreaders used to lift steel plates mainly include tongs (hooks), vacuum suction cup spreaders, and electric permanent magnet spreaders.

Steel plate spreader is widely used in shipyards, bridges, civil construction, steel structures and other industries for steel plate hoisting and handling, and there are many types of steel plate spreaders, if you choose blindly, it will bring unnecessary trouble to work and production, and more serious will cause safety accidents. Therefore, these selected points of the steel plate spreader must be known. 1. The selection of the model and type is based on the operation purpose or the lifting objects such as steel plate and section steel.

For example, according to the different hoisting directions, Eagle brand steel pliers can be divided into horizontal lifting steel pliers (horizontal hoisting of steel plates), vertical lifting steel pliers (longitudinal hoisting), horizontal hooks (horizontal hoisting), spiral pliers (omnidirectional hoisting) and other types; There are also special tongs for concrete product lifting, section steel lifting, steel plate scratch-free lifting, sheet pile hoisting, etc., which can be selected according to their specific use cases. 2. The use load and the selected use load of the plate thickness can be selected according to the weight of the steel plate, or the lifting method of using several steel cables; The thickness of the plate, commonly known as the opening size, can be selected according to the thickness of the steel plate or the width of the mounting part.

Please be sure to use it within the specified range. 3. There are dozens of brands from domestic to imported, so we should comprehensively consider the brand, product quality, quality, and after-sales support capabilities when choosing. But in any case, the steel plate spreader is a lifting tool, and it is crucial to ensure the normal lifting and safety of the steel.

Commonly used lifting tools and lifting machinery include jacks, inverted chains, snap rings, rope clamps, hooks, hand hoists, grinders, pulleys and pulley groups, etc.

1 Luge and block set.

The pulley and the block group are the most commonly used lifting tools in lifting, hoisting and handling operations.

The pulley is composed of hook links, pulleys, shafts, bushings and splints. According to the number of wheels, it is divided into single-door, double-door and multi-door pulleys. According to the connection mode between the pulley and the hanging object, it can be divided into four types: hook type, chain link type, lifting ring type and hanging beam type.

Generally, small and medium-sized pulleys mostly belong to the hook type, chain link type and eye type, while the large block adopts the eye type and the beam type. According to the contact between the wheel and the shaft, it can be divided into two types: sliding bearings and rolling bearings. According to whether the splint can be opened, there are open pulleys and closed pulleys.

The splint of the open pulley can be opened, which is convenient for loading ropes, and the general is a single-door pulley, which is often used at the foot of the lever as a guide pulley. Luge is divided into fixed block and movable block according to different ways of use.

The pulley group is composed of a certain number of fixed pulleys and movable pulleys and ropes, because when lifting heavy objects, not only to change the direction of force, but also to save force, so that the fixed block or movable block alone can not solve the problem. If the stator and movable pulley are linked together to form a pulley group, it can save effort and change the direction of force.

If the multi-door fixed block and the movable block are connected together to form a multi-door block group, the heavy object can be lifted with a small force, as long as the winch of 0 5-15t is used to pull the end of the block group, it can lift several tons or hundreds of tons of objects. Therefore, the block group is a widely used lifting tool in lifting work.

2 jacks.

Jacks, also known as weightlifts, are widely used in lifting work. It can use very little force to elevate very heavy mechanical equipment, and can also correct the deviation of equipment installation and the deformation of components. The jacking height of the jack is generally 100-400mm, and the maximum lifting capacity can reach 500t.

Jacks are divided into three types: rack type, spiral type and hydraulic type according to their structure and working principle. When using the jack, it should be laid flat, and the top and foot parts should be padded with wooden boards; The jack should not be overloaded, and the height of the jacking should not exceed the marking line on the piston;

There are two kinds of cranes used to lift steel pipes.

A traditional spreader. Rigging, clamps. The downside is that it's not reliable enough. There may be loosening, etc. The advantage is that it is cheap.

An electromagnetic spreader. The advantage is that the adsorption is reliable. The disadvantage is that it is higher than the traditional one. In addition, electromagnetic spreaders are divided into two types. An electromagnetic spreader. An electric permanent magnet spreader. The electric permanent magnet spreader has the characteristics of power-off without loss of magnetism.

There is an electric permanent magnet spreader for lifting steel pipes, and the electric permanent magnet spreader can be divided into.

1. Lifting of a single steel pipe.

2. Lifting of multiple steel pipes.

Generally, the electric permanent magnet spreader hanging tube-shaped workpieces are: ordinary steel pipes, cast pipes, etc., and there are also electric permanent magnet chucks used in automated manipulators to handle pipe fittings to complete palletizing and other requirements.

There are two types of spreaders for lifting steel pipes.

1. Traditional spreaders, hooks, snap rings, and beam spreaders.

2. Magnetic spreader. The magnetic spreader is divided into manual magnetic spreader and electromagnetic magnetic spreader. Electric permanent magnet magnetic spreader.

Each has its own advantages and disadvantages. <>

The hoisting of the lifting steel pipe has, hooks: ring eye hook, rotary hook, horn sliding hook, nose hook, wire rope clamp, S hook, national standard hook, D

Type shackles, bow shackles, snap rings: round lifting rings, pear-shaped lifting rings, long lifting rings, strong lifting rings, special-shaped lifting rings, rotating lifting rings, hanging beams: including bearing beams and connecting rigging, is a special beam spreader for lifting the lifted objects. There are tubular type, steel plate type, channel steel type, citrus frame type, etc.
