Wheel loaders are wheeled construction machines that efficiently load loose materials such as soil, sand, and stone using a hydraulic boom and bucket. Widely used in construction, mining, and logistics, they are characterized by powerful performance, flexible operation, and intensive maintenance requirements. Therefore, understanding the common faults that can occur during wheel loader operation and mastering on-site maintenance methods are crucial for ensuring normal operation and extending the service life of the equipment. This article will analyze common faults based on the working characteristics of wheel loaders, mainly including engine faults, hydraulic system faults, transmission system faults, and electrical system faults, and provide corresponding on-site maintenance solutions.

A sugarcane loader is a wheeled agricultural machine equipped with a hydraulic claw arm that can grab, lift, and rotate harvested sugarcane onto transport vehicles, efficiently replacing manual labor and widely used in major sugarcane-producing areas. After daily operation, ensuring proper lubrication and maintenance of the drive system and chains is crucial for extending the equipment's lifespan. The following will detail how to effectively lubricate and maintain the drive system and chains of a sugarcane loader after daily operation.

Hydraulic cylinders and seals are critical components of the hydraulic system, directly affecting the performance and reliability of the loader. We understand the crucial role of the hydraulic system in the overall operation of the machine. Regular maintenance and upkeep are essential for extending the service life of these components, improving work efficiency, and reducing malfunctions. This article will detail the maintenance and upkeep measures for the hydraulic cylinders and seals of telescopic boom loaders.

Skid steer loaders are a "small but versatile" piece of construction equipment. They are compact, flexible to operate, and can be fitted with various attachments, making them widely used in earthmoving, landscaping, municipal engineering, and agriculture. Despite the variety of models, their basic structure and maintenance logic are similar. As a frontline maintenance engineer, I will combine years of field experience and industry inspection standards to provide a detailed explanation of the daily inspection and maintenance procedures for skid steer loaders after daily operation, helping to reduce malfunctions, extend lifespan, and improve safety.

As one of the most important pieces of equipment in construction machinery, the working efficiency and service life of a loader largely depend on the maintenance of its attachments. Loader attachments such as the bucket, bucket teeth, and quick-connect couplings are core components for efficient operation, and their maintenance directly affects the loader's performance, operational stability, and safety. This article will analyze the key points and precautions for the maintenance of these loader attachments from a professional perspective, helping operators extend the equipment's service life and improve work efficiency.

After sugarcane harvesting, sugarcane loaders should not be simply shut down. Proper maintenance not only extends machine life and reduces downtime, but also prepares the machine for the next harvest and lowers operating costs. Especially in large-scale sugarcane loading operations in mining, industry, or agriculture, where equipment loads are high and operating environments are harsh, the post-harvest "rest" and "repair" phase is crucial. This article analyzes the systematic maintenance procedures for sugarcane loaders after harvesting from a professional perspective, applicable to post-harvest maintenance of equipment in mining and agricultural environments.

Sugarcane loaders are specialized agricultural machinery used for efficient loading and unloading of sugarcane during the harvesting process. They primarily replace manual loading and unloading, significantly reducing labor intensity and enabling mechanized loading operations from the field to transport vehicles. Their core function is to grab, lift, and transfer bundles or loose sugarcane. Traditional manual loading methods are not only labor-intensive and inefficient, but have also shown bottlenecks in the trend towards large-scale and mechanized production.

Telescopic loaders, as a type of high-efficiency construction machinery, play an increasingly important role in construction, logistics, and disaster relief due to their superior lifting height and flexible working radius. They are widely used in high-altitude operation scenarios such as construction, mining, and ports. Thanks to their unique telescopic boom design, telescopic loaders can provide a greater working range and efficiency in high-altitude environments. However, improper operation during high-altitude operations can lead to serious safety accidents. Therefore, understanding and adhering to safety precautions for high-altitude operations is crucial to ensuring the safety of equipment, personnel, and the working environment.

Backhoe loaders (also known as backhoe excavators or bulldozers) combine loading and bulldozing/excavation functions, making them a common type of construction machinery used on construction sites for earthmoving, excavation, and bulldozing tasks. In bulldozing operations, the bucket, as one of the most important components of the backhoe loader, undergoes a fundamental change in its force distribution—from tensile force primarily for excavation to pressure and torque primarily for pushing. Its performance directly impacts work efficiency and equipment lifespan. However, the bucket is prone to deformation during operation due to various reasons, which not only affects work efficiency but can also lead to equipment damage, production stoppages, and unnecessary repair and maintenance costs.

In industrial and mining environments, loaders (whether wheeled or tracked) often face complex and harsh ground conditions. Muddy/soft soil and snow/ice conditions are particularly challenging, each presenting its own unique characteristics in terms of slippage/sinking risks, equipment wear, and operational strategies. These harsh environments not only test the mechanical performance of the equipment but also place extremely high demands on operational procedures. This article systematically analyzes the different precautions for wheeled/tracked loaders operating in muddy and snowy environments from four dimensions: ground conditions, equipment adaptability, operating procedures, maintenance, and safety management, highlighting the similarities and differences between the two. It aims to provide a reference for equipment selection, operator training, and on-site management.
