There are often consumers who are confused when buying furniture. What kind of furniture can be used to buy it? Some of them even buy it home and wonder if it is truly high-quality furniture. Let's learn about some of the advantages and disadvantages of furniture. Common sense, I hope to help everyone in the purchase of furniture. 1. Detect dry moisture of wood: When the moisture content is high, the wood is easy to warp and deform. Under normal circumstances, the moisture content of the furniture must not exceed 12%. Consumers usually do not bring their own test instruments when purchasing furniture, so they can use hand-touch methods to touch the underside of the furniture or place that is not painted inside. If moisture is felt, the wood moisture content is at least 50. % or more, should not be purchased. 2. Examine the material of the furniture: The surface material of the furniture generally requires the use of hardwood materials, such as manchurian ash, eucalyptus, etc. These wood materials are relatively strong and can bear weight, while internal materials can be considered for other materials. If wood is found to have insect eyes and drop-off phenomena, it indicates that the drying of the wood is not complete. Such furniture cannot be bought because the wormholes will become larger and larger. After checking the surface, you should also open the home cabinet door and the drawer door to see if there is any decay inside the material. 3, the structure is solid: For desks, tables and other furniture can be shaken by hand, look stable. For the sofa, sit and sit, shake left and right, do not move, don't feel soft, and there is no sound, which means that the blinking structure is more reliable. 4, whether the formation of four feet: whether the four-foot furniture is flat, the furniture will be placed on the ground flash will know. Some furniture has only three legs landing, stability is certainly not good. It also depends on whether the table is straight and cannot be arched or collapsed. If the table is raised, the glass plate will rotate; if the table is recessed, the glass plate will be broken by a pressure. In addition, we must pay attention to the inspection of the cabinet doors. The drawers should not be too large. We must pay attention to the straightness and straightness, and the doors must not be sagging. 5. Whether the edge and edge are flat and tight: the edge is not flat, indicating that the internal material is wet, and the edge will be removed after a long time. The edge banding is preferably rounded and cannot be right-angled. Edges sealed with wooden strips are prone to dampness or cracking; furniture plaited with plywood is nailed with nails. Pay attention to whether the nails are flat and whether the color of the nails is the same as that of other parts. Usually the nail hole is covered with putty. It is necessary to pay attention to whether the putty is bulging. If it is bulging, putty will fall out of it. 6. Check the quality of the mirror: When selecting furniture with mirrors, such as dressers, clothes, mirrors, etc., pay attention to whether or not the mirror is distorted and remove the color. Check if there is any liner on the mercury at the back of the mirror. And the backboard, no backplane is not qualified, no paper no line, because this will wear away mercury. 7. Whether the paint is smooth: The paint part of the furniture should be smooth, smooth, not saliva, wrinkle-free, flawless. The corners cannot be right-angled at right angles, because the straight edges are easy to collapse and paint off. 8, sofa, soft and soft moderate moderate: When selecting a sofa soft bed, it should be noted that the surface should be smooth, not uneven, soft hardness should be moderate. The selection method is to take a seat, and then handcuffed to see if the spring rings. If the springs are laid out irrationally, the spring will make a spring and it will make a sound. Second, we must also pay attention to whether the quilting breaks, jumpers, the density of the corner angle tooth.

At present, the largest marine hydraulic winch is 350T, and the weight of the equipment reaches 150T.

According to the reel form, it is divided into single reel and double reel.
According to the reel distribution, there are parallel double reels and front and rear double reels.
The main technical indicators of hydraulic winches include rated load, supporting load, rope speed, rope capacity, etc.
A winch is a light and small lifting device (see hoisting machinery) that uses a reel to wind a wire rope or chain to lift or tow heavy objects, also known as a hoist. The winch can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding volume and convenient displacement. The winch is also known as the hoist. The product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient transfer. It is widely used in construction, water conservancy projects, forestry, mines, docks, etc. for material lifting or flat towing, and can also be used as modern electronic control Supporting equipment for automatic operation line.
According to the power, the winch is divided into three categories: manual, electric and hydraulic.
The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet wheel and pawl), which can keep the heavy object in the required position. The manual winch used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used in places where the lifting capacity is small, the facilities are poor, or where there is no power supply.
Electric winches are widely used in places with heavy work and large traction requirements. The electric motor of the single-drum electric winch (pictured) drives the drum through the reducer, and a brake is installed between the electric motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotation, there are also double-drum and multi-drum winches. Generally, a winch with a rated load lower than 10T can be designed as an electric winch.
The hydraulic winch is mainly a winch with a larger rated load. Generally, the winch from 10T to 5000T is designed as a hydraulic winch. The winch can be divided into:
Marine winches: Marine winches can be divided into drag winches, mooring winches, anchor winches, traction winches, etc.
Engineering winch: Mainly used in engineering, with functions such as hoisting and hoisting as the main function.
Mine winches: divided into hoisting winches, dispatching winches, shaft sinking winches, column return winches, rake mine winches, column return winches, etc.
Cable winch: mainly used when laying cables.
