Tips for carrying heavy loads, use tools when carrying heavy loads of more than how many kilograms

When carrying heavy loads, for the safety of the lower back, the following two principles should be followed:

Keep your back straight and keep your spine in a neutral position, maintaining its natural physiological curvature.

Avoid sudden changes in spinal load, such as rapid bending, lateral flexion, or rotation.

Here are 4 ways to lift heavy objects safely.

Deadlift way.

In the field of fitness, the deadlift is an action for heavy equipment, so it can be used as a reference when carrying heavy objects.

Keep your back straight and try to keep weights as close to your body as possible.

This technique is especially useful when moving objects to higher heights.

Deadlift + single-arm support.

If one arm must be used in some cases, the other arm can be placed on the thigh for support, trying to keep the sides balanced.

Squats.

Again, bring the object closer to the body, keeping the back straight and allowing the erector spinae.

Maintain the stability of the spine.

The difference between a squat and a deadlift: a deadlift to stretch the hip joint.

Dominantly, squats are performed by extending the knee joints.

for the lead. The most obvious difference is the degree of bending of the knees, with the hips and thighs being significantly lower in the squat, squatting first and then getting up.

Lunge + arm support.

In the form of a lunge, the object is lifted with one arm, and the two feet can be slightly adjusted according to the weight of the object.

Suitable for use when the weight of the object is moderate.

Rise pose! Do you really carry heavy loads?

Tools such as carts should be used to carry heavy objects exceeding (25) kg; Carrying heavy objects should be carried with force (legs) and try to avoid (waist) force.

Ground cattle are a means of transportation, also known as trailers, forklifts, and trucks.

Abbreviated as "cattle" is a kind of transportation device in the supermarket, which is used for the transportation of stores and warehouses in large supermarkets. It has four running wheels and a steering wheel, the upper part of which is called a "bull's head", which acts like a bicycle handlebar and is used to steer and raise the height of the two rear supports.

means of transport. Generally, supermarkets will see a convenient and small means of transportation that uses hydraulic jacks to lift. It is generally yellow in color, and it is relatively slender in itself, which is very convenient for movement.

There was a handle, two forks with wooden boards. After forking on the pallet, it looks like the volume will be relatively large, and it can generally be transported.

One or two tons or so of something. A large number of them can be seen by entering any name in **.

When carrying heavy objects in life, you must use the correct posture, otherwise it will hurt your waist.

1. Correct posture: squat, lower the center of gravity of the body, get close to heavy objects, tighten the core, and keep the back as straight as possible.

2. Rely on the strength of your legs to lift heavy loads, not your waist.

3. When lifting heavy objects encounters a change of direction, do not rely on the twist of the waist to change direction! Move with your feet to complete the change of direction!

After lifting heavy objects, many people experience neck and shoulder pain, strained arms, or a lack of standing up in the waist. Improper posture and excessive force when lifting heavy objects can lead to inflammation of upper limb muscles, tendon strain, and even joint injury. Whether it's carrying luggage or carrying heavy loads on a daily basis, you should avoid the following wrong postures.

1. Wrong posture of dragging suitcases:

Keep the arms away from the torso. The angle between the arm and the body is too large, which increases the load on the upper limb and easily causes muscle strain. Excessive extension of the arm to tighten the biceps brachii can cause inflammation of the muscles and tendons for a long time.

Correct posture: The arms are as close to the body as possible to reduce the load on the biceps; The height of the handle should be appropriate, and it is better to be able to hold the handle tightly after the arm is vertical; Start smoothly so as not to strain your muscles.

2. Wrong posture for lifting heavy objects:

Sideways suitcase. This increases stress on unilateral muscles and joints in the body; Excessive exertion and rapid starting during lifting will suddenly increase the load on the upper limbs, and it is easy to strain muscles and tendons.

Correct posture: Squat down and hold heavy objects, keep your back straight, so as not to strain your back muscles; When holding heavy objects, your arms should be as close to your body as possible; Squat and stand up using your thigh muscles, not your lower back.

In addition, don't forget to warm up before carrying heavy loads, 10 to 15 seconds per set, and then do it on the other side, repeating 5 to 6 times to help prevent muscle strain.

Exercise 1: Stretch the biceps. Stand sideways against the wall, make a fist with your left hand, raise your arm to shoulder height, and press your mouth against the wall until your biceps are slightly pulled.

Exercise 2: Stretch the pectoralis major and biceps. Stand up straight with your hands clasped behind your back; Hold your body still and raise your hands as much as possible until you feel a slight pull on your pectoralis major and biceps.

Exercise 3: Stretch the deltoid muscles and back shoulder muscles. The right hand is placed in front of the chest and stretched horizontally; Flex your left hand upwards and press your right hand towards your body until you feel a slight pull on your deltoid muscles and back shoulder.

Exercise 4: Stretch your forearm muscles. Extend your right hand straight ahead, shoulder-height, palms facing up, arms relaxed; Press your left hand on the palm of your right hand and press towards your body until you feel a slight tug on your forearm muscles.

Lifting heavy objects is very common in daily life and work, such as construction workers moving cement, plasterers moving tiles, usually moving bags of rice at home, etc., if you do not pay attention to the correct posture, it will often cause waist damage. It is important not to bend over with straight knees to move, because in this posture, when lifting heavy objects and straightening the waist, the sacrospinous muscles must first contract with greater force to stretch the upper body trunk and lift the heavy objects, and the ** of this force is mainly the starting point of the sacrospinous muscle, which is easy to cause sprains. The correct posture should be to first bring your body as close to the weight as possible, and then bend your knees, hips, and waist to lift the object.

This posture does not need to use greater force to stretch the waist, mainly by stretching the hips and knees; Hip extension and knee straightening mainly rely on the gluteus maximus and quadriceps muscles, which are stronger and have longer muscle fibers, and their work efficiency is much stronger than that of the sacrospinous muscle, so there is less chance of being torn and less likely to cause lower back injuries.

Commonly used handling methods, depending on which type of handling method you support, are you talking about moving goods? In fact, there are two ways to move goods, the first is the mechanical handling method using the machine to handle, this handling method is characterized by a particularly large amount, and it is particularly easy to move well, especially easy to succeed, and this is the case.

The second type of handling method should be called the manpower handling mode, the manpower handling method is the ancient handling method, this kind of handling method is for some small amounts, mobility is relatively strong, but if the amount is too large, the human handling method will not work.

Commonly used handling methods are, manpower handling, car handling, train handling, ship handling, and air transportation.

The correct posture for carrying heavy objects is: squat down and pick up the object with your hands, and let the object close to your chest after picking it up, because the closer you are, the less effort you have, and it is not easy to fall, and the body should be kept upright as much as possible during the handling process.

1. First of all, spread the legs apart, one leg slightly forward, and then squat down, straighten the waist pole, and tighten the abdomen.

2. Then lift the heavy object smoothly, get up slowly, and put the center of gravity of the object as close to the body as possible.

3. In the process of moving objects, keep your back straight, even if the object is heavy, try to bend your legs to adjust it, and don't bend over.

In the action of lifting a heavy object, the muscles of the whole body are involved. Among them, the waist bears particularly much force. According to the principle of static equilibrium, when lifting an object weighing 25% of body weight, the pressure exerted on the second lumbar vertebra is about four times the body weight, and the burden on the lower back can be seen.

Therefore, when facing heavy objects in life, if you can move in other ways, try not to move them recklessly, so as to avoid accidents.

Precautions when handling heavy loads

1. Use large joints, bring heavy objects close to your body and keep your waist upright.

2. According to the form of the object to be carried, choose whether you need to use auxiliary tools, such as ropes, Li Chajian bags, carts, etc.

3. When carrying irregular objects such as flour and rice, it is recommended to lift heavy objects or use tools such as carts to carry them due to their soft shape, avoid using postures such as lifting and carrying, and avoid repeated exertion on one side of the limb or small joint.

4. It is necessary to do what you can, and use a small weight and more times to carry it, rather than a large weight, a small number of times and a long time.

5. Warm-up activities before handling can reduce the occurrence of physical injuries in Qingchun.

Here are some common ways to move items:

1.Use a trolley or flatbed: For heavier or larger items, you can use a trolley or flatbed for handling. Place the item on the cart, make sure it is securely fastened, and use the trolley's handle or handle to push the item.

2.Use handling tools: For bulky and heavy items, special handling tools such as pulleys, handling belts, slings, etc., can be used to reduce the burden of handling and improve efficiency.

3.Organize manpower: For lighter items, you can organize friends, family, or colleagues to work together to move the items together. Make sure you work as a team and communicate your removal plan and safety precautions to avoid injury or damage.

4.Use the center of gravity and strength: Learning to use the center of gravity and force correctly can make it easier to carry bent goods. Keep your body balanced and use your thighs and core muscles to provide stability and strength, reducing stress on your arms and back.

5.Use the right gear: Use the appropriate gear to move items as needed. This may include safety gear such as gloves, non-slip shoes, protective glasses, and helmets, as well as aids such as ropes, straps, and mats.

6.Planning and preparation: Before moving, assess the weight, shape, and size of the item, plan the handling path, and make sure that obstacles that could cause tripping or collision are cleared.

7.Pay attention to safety: During the handling process, pay attention to protect the safety of yourself and others. Follow proper posture and technique, avoid twisting or strenuous movements, use appropriate tools and gear, and strength that matches the weight and characteristics of the item being moved. <>

Moving is inevitable to avoid the handling of large items, and the process of moving large items is particularly careful. Seal moving companies have masters who specialize in handling large items. The skills of handling large items still need to be mastered, so let's take a look at the skills of handling large items.

Moving is inevitable to avoid the handling of large items, and the process of moving large items is particularly careful. Seal moving companies have masters who specialize in handling large items. The skills of handling large items still need to be mastered, so let's take a look at the skills of handling large items.

Seal movers are moving large items, and they usually put some small items under the first floor, which is not easy to mess up.

Large items need several people to move together, so the seal moving company moving team will have to divide labor in advance and draw up a detailed division of labor plan for a wide grip, so that the relevant personnel who move know how they should move and which aspect they should be responsible for.

In the process of transporting large items upstairs, try to avoid friction, and relevant personnel must carefully guard their own parts, do not let the items be collided, and try to maintain a stable state.

The advantage of choosing a seal moving company for large items is that the seal moving company has a very complete set of equipment to assist in the handling of large items. It's easier to carry and faster.

Before moving bulky items, consumers and moving companies should communicate and discuss, and try to choose to move in good weather, because the work of moving bulky items is very difficult, and if it is windy and rainy, it will inevitably be affected in the handling process.

1. Using some tools, such as ropes, will be more labor-saving in handling.

2. Disassemble all the parts that can be removed from the cabinet to reduce weight.

3. Multi-person handling, some heavyweight cabinets, use more people to share the weight. It is more labor-saving.

4. Install rolling wheels at the bottom of the cabinet and use the rolling method to carry it, which will be more labor-saving.

5. Put a round wooden stick under the cabinet, or a module that can be slid by those who suspect the key, and use it to move instead of the group to carry it, which will save a lot of effort.

6. The use of machinery to replace manpower, now is an industrial society, you can rent machinery to help transport, the most labor-saving.
