Causes and solutions of rear wheel warping of wheel loader


When we use wheel loaders, there may be various types of problems, of which the rear wheel of the loader is a very dangerous problem, then do you know what causes the rear wheel of the loader to tilt? Let's take a look at OXPLO brand, a professional wheel loader manufacturer.

1. The load is too heavy: the weight carried by the loader during work exceeds the carrying capacity of the rear wheel. This may be due to overloading or incorrect cargo distribution. When the rear of the loader carries too much weight, the rear wheel will lose its power to contact the ground, resulting in the rear wheel warping. We should properly evaluate and control the load of the loader and comply with the load rating limits of the loader. Distribute the goods properly, keep the center of gravity in the right position, and avoid excessive rear weight.

2. Unbalanced loading: When the loader's cargo is placed in an unbalanced or incorrect position, the center of gravity will lean toward the rear, causing the rear wheel to tilt up, which may occur when the cargo is too concentrated in the back of the machine or incorrectly distributed in the loading bucket. In daily operations, we should balance and distribute the goods correctly, avoid concentrating too much weight in the back of the loading bucket, and pay attention to balance and evenly distribute the goods during the loading process.

3. Wrong operation: The operator may operate under incorrect conditions, such as excessive lifting of the loading bucket or sudden acceleration. This error may cause the rear wheel of the loader to tilt up. When operating the loader, it is necessary to follow the correct operating procedures and techniques to avoid excessive lifting of the loading bucket or sudden acceleration to maintain the stability of the loader.

4. Ground conditions: Uneven ground or unstable ground may cause the rear wheel to tilt up. For example, when a loader is working on a slope, the rear wheels may lose contact due to the tilt of the ground. We need to be extra careful when working on uneven or unstable ground. Try to choose a flat and stable working area to ensure that the ground can provide adequate support.

5. Mechanical failure: Mechanical failure of the loader, such as suspension system failure, brake failure, etc., may cause the rear wheel to warp. We should regularly check and maintain the mechanical system of the loader, including the suspension system and the brake system. If any fault or anomaly is found, repair and maintain it in time.

What is the impact on operator safety when the rear wheel of the loader is cocked?

1. Increase the risk of tipping over: The rear wheel cocking will cause the loader's center of gravity to shift, increasing the risk of tipping over. Tipping accidents can result in serious injury or even fatal consequences.

2. Handling difficulties: the loss of the rear wheel to the ground will cause the operator to lose the ability to control the loader. The operator may not be able to control the direction and speed of the loader's movement, increasing the likelihood of accidental collisions or other dangerous situations.

3. Brake failure: When the rear wheel is cocked, the braking effect of the loader will be seriously affected. This reduction in braking force may cause the operator to be unable to stop or slow down in a timely manner, increasing the risk of collision with an obstacle or other accident.

4. Unstable work platform: The rear wheel cocking will make the loader's work platform become unstable, which may cause the operator to lose balance in the loading bucket or the cab. This can cause the operator to fall, slip out, or injure himself.

5. Operator crush risk: When the rear wheel is cocked, the loader's center of gravity will move forward, which may cause the operator to be squeezed between the cab or other components, causing injury or trapping.

As a result, the rear wheel of the loader is warped and poses a serious threat to the safety of the operator. The operator should always pay attention to the stability and operating procedures of the loader and follow safe operating guidelines to reduce the occurrence of rear wheel warping and associated risks. When the rear wheel of a wheel loader is cocked, what safety measures can the operator take to save it?

1. Stop operation immediately: If the operator is aware of the rear wheel of the loader, it should immediately stop the movement of the loader. Stopping operations can avoid further instability and risk.

2. Stay calm: In the case of a cocked rear wheel, the operator needs to remain calm and collected. Do not panic or make sudden manipulative movements, which may exacerbate instability.

3. Try to maintain stability: the operator should try to maintain its own stability and balance, avoid sudden movement or standing in an unstable position. If possible, try to find solid support to ensure your own safety.

4. Find a safe area: If the rear wheel cocking situation persists, the operator should move the loader to a safe area as soon as possible. This could be a flat surface or other area that provides enough support.

5. Keep distance from others: When the rear wheel is cocked, the operator should ensure that the surrounding personnel maintain a safe distance to avoid potential injury to other personnel.

6. Seek professional help: If the operator is unable to resolve the rear wheel cocking issue or feels unsafe, seek professional help immediately.

Due to the rising force of the loader, the driver is usually in the process of digging solid soil and stone mountains, if the operation is not appropriate, the latter two wheels will be warped, or even very high from the ground. In the long run, it will cause great damage to the loader.

1. Loss of stability: A cocked rear wheel can cause the loader to lose balance, making it unstable, which can cause the loader to overturn or roll over, posing a serious safety risk to the operator and nearby people.

2. Difficult operation: the rear wheel cocking will make the operation of the loader difficult and uncontrollable. The operator may not be able to accurately control the movements and movements of the loader, which increases the likelihood of accidents.

3. Reduced digging force: rear wheel warping will cause the loader to lose contact with the ground, thereby reducing the digging ability and efficiency. Operators need to stop work and readjust the loader's position and attitude to restore stability, which can lead to work disruption and reduced productivity.

4. Ground damage: The rear wheel warping will cause severe friction and impact between the rear of the loader and the ground, damaging the ground surface. Especially on weak or unstable ground, this can lead to ground collapse, subsidence or other site hazards.

5. Equipment damage: Rear wheel warping will put additional stress and pressure on the structure and mechanical components of the loader, which may lead to equipment damage and failure, which will increase the cost of repair and maintenance, but also cause work interruption and time delay.

6. Casualties: If the rear wheel of the loader is tipped over or overturned, the operator and nearby personnel may be injured or even killed. This is a serious safety risk due to loader instability.
