According to different methods of use, winches can be divided into four types: manual winches, electric winches, pneumatic winches, and hydraulic winches. At present, the largest marine hydraulic winch is 350T, and the weight of the equipment reaches 150T.

Don't mess with it. Before storing the remaining pesticides, read the instruction manual carefully and take the pesticides that have been ineffective in the wild. Do not throw them away in order to avoid poisoning and polluting the environment.
Don't mess with the label and instruction manual of the pesticide, and replace the damaged bottle and bag. For pesticides whose labels have been lost or blurred, the name, usage, dosage, expiration date, and scope of use must be rewritten on paper and attached to the bottle or bag for proper use.
It is necessary to pay attention to the implementation of sealed bottled liquid pesticides, which should have an inner cover and tighten the cap to avoid the volatilization of pesticides and cause air pollution. Bagged powder pesticides should be sealed with double-layer plastic bags to prevent moisture and agglomerate from deteriorating.
Pay attention to maintaining temperature. Most powder pesticides are susceptible to high quality at high temperatures. The higher the temperature, the easier the pesticide will melt, decompose, volatilize, and even burn and explode. Some emulsion pesticides are easy to destroy their emulsifying properties and reduce the efficacy after encountering high temperature. Some bottled liquid pesticides tend to freeze when they encounter low temperature, form a block, or freeze the bottle, and should be kept in the storage of such pesticides. The indoor temperature is above 1 °C. In addition, phoxim pesticides are afraid of light, and long-term exposure to light can cause decomposition and deterioration of pesticides. Avoid high temperature and sun exposure during storage.
It is necessary to pay attention to maintaining dry powder pesticides and plant growth regulators, which are easy to absorb moisture and agglomerate. Therefore, the place where the pesticides are stored should be kept dry to prevent rain and snow. Also leave a window for ventilation and keep the humidity below 75%.
Pay attention to classified storage. According to chemical composition and properties, pesticides can be divided into three categories: acidic, alkaline and neutral. Acidic pesticides such as trichlorfon, dimethoate, dichlorvos, etc.; alkaline pesticides such as stone sulfur mixture, Bordeaux mixture, etc.; neutral pesticides such as 1605, methamidophos, phoxim and so on. These three different pesticides should be stored separately during storage and storage, and the distance should be kept above 0.5 meters. Otherwise, the pesticides will affect each other and cause deterioration. In addition, the two kinds of pesticides that cannot be used can not be mixed in one bottle to avoid failure.
Pay attention to prevent accidents. All pesticides have different degrees of toxicity. In storage, it is best to put them in a counter or wooden box and lock them outside. Pesticides should not be placed together with grain, oil, seeds, feed, vegetables, etc.; emulsions and fumigants should not be placed together with flammable or explosive materials such as matches, oil, firecrackers; they should not be stored in the bedroom and often with people and animals. Access to the area should be kept in a ventilated, dry, cool place.
It is necessary to check frequently for all kinds of pesticides to be kept, and to check regularly to prevent the loss of pesticide deterioration caused by the ground returning to the ground, the house leaking rain, and the packaging is broken.
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.
How to keep the remaining pesticides in winter
There are not many opportunities to apply pesticides in winter, or they basically stop. Some farmers have not used up the pesticides, so how to properly preserve the pesticides, avoid the failure of pesticide volatilization and human and animal poisoning accidents?
