Environmental requirements and precautions for the use of loader accessories

[DIG-DOG]

1. Overview of the environmental requirements for loader accessories

Different operating environments have different requirements for loader accessories. Reasonable matching and standardized use are the key to ensuring equipment reliability. According to the "Analysis of Environmental Adaptability of Loader Accessories", the following aspects need to be paid attention to:

1. Temperature conditions
Under extreme climates of high or low temperatures, the performance of accessory materials will change.

High temperature environment requirements: The hydraulic system and transmission system need to use high temperature resistant hydraulic oil, and the seals need to have high temperature aging resistance to ensure that the "loader hydraulic system works stably in high temperature environments".

Low temperature environment requirements: Low freezing point lubricants should be selected, and key rubber seals should have good low temperature flexibility to ensure the "low temperature resistance of loader accessories in cold areas".

2. Wet and corrosive environment
When working in ports, mines or rainy areas, accessories are exposed to high humidity environments for a long time and are very susceptible to corrosion.

Select anti-corrosion treated metal parts, such as hot-dip galvanizing or surface spraying of corrosion-resistant coatings, to ensure the "application of loader corrosion-resistant accessories in wet environments".

Apply anti-rust oil to the connection parts regularly to avoid fatigue damage caused by rust.

3. High dust environment
In environments such as quarries and cement plants, a large amount of dust particles in the air will accelerate the wear of accessories.

The air filter needs to have a denser filter structure and be cleaned or replaced regularly to achieve the "best protection effect of the loader air filtration system in a high dust environment".

Moving parts such as hinge points and pins need to use heavy-duty dust seals to reduce wear.

4. Strong impact and vibration environment
In high-impact working environments such as gravel yards and building demolition, accessories must have extremely high impact resistance.

Structural parts such as booms and buckets must be made of high-strength wear-resistant steel to ensure "improved impact resistance and durability of loader structural parts".

Use reinforced tires and reinforced axles to adapt to frequent impact loads.

2. Analysis of environmental adaptability of main accessories
For more specific explanation, the following are the adaptability requirements of several important accessories in different environments:

1. Engine system
In high temperature environment, the heat dissipation capacity of the cooling system should be strengthened to avoid "common causes of loader engine overheating failure".

Starting is difficult in low temperature areas, and a preheater can be installed or a low temperature starting system can be used.

2. Hydraulic system
Hydraulic oil is very easy to absorb water and deteriorate in high humidity environment. It is necessary to use a sealing ring with waterproof function and regularly test the oil quality to meet the "loader hydraulic system waterproof protection standard".

3. Braking system
When working in high slope or muddy environment, the brake system has a large load and needs to be equipped with a wet brake bridge to improve the "reliability of the loader brake system in harsh environment".

4. Electrical system
For environments where wading operations are often carried out, such as river construction, electrical connectors with IP67 or above must be selected to ensure the "waterproof and dustproof performance of the loader electrical system".

3. Precautions for the use of loader accessories
In order to ensure that the accessories perform at their best in different environments, special attention should be paid to the following aspects:

1. Regular inspection and preventive maintenance
Follow the "daily inspection and maintenance process for loader accessories" to perform periodic inspections on the engine, hydraulic and transmission systems to promptly detect hidden dangers and avoid major repairs caused by environmental deterioration.

2. Choose suitable lubricants and protective products
Reasonably select lubricants of different viscosity grades and functions according to the operating environment. For example, it is recommended to use greases containing extreme pressure additives in high-dust environments to ensure "lubrication protection for high-load operations of loaders".

3. Avoid overload operations
In extreme environments, excessive overloading will accelerate the loss of accessories. Reasonable control of the operating load and compliance with the "standard load operation specifications for loaders" are crucial to extending the life of the entire machine and accessories.

4. Correct use and operating specifications
Improve operator skills and train "correct operating skills for loaders in harsh environments" to reduce early damage to accessories caused by improper operation.
