Manual hydraulic pallet trucks are the most common handling equipment in warehouses, logistics, and production workshops. They are simple in structure and easy to operate, effectively improving handling efficiency and reducing physical exertion. However, these devices are prone to wear, oil leaks, and component fatigue under high-frequency operation. Therefore, daily maintenance is crucial. Proper maintenance after each operation can extend the equipment's lifespan by more than 30% and prevent 80% of sudden failures. Maintenance is not only about extending equipment life but also a key aspect of ensuring operational safety.

The brake system is one of the most critical safety features of a mini dump truck. Whether operating in muddy and complex terrain on construction sites or in stop-and-go conditions on narrow roads, a well-maintained brake system directly impacts the safety of personnel and equipment. Therefore, proper maintenance is crucial. This article will detail the maintenance methods and inspection points of the brake system, taking into account the characteristics of mini dump trucks.

In mini dumpers (also known as small dump trucks), a type of specialized construction machinery, the chassis is not only the "skeleton" that carries the entire vehicle's load, but also the core platform connecting the power transmission system, suspension system, braking system, and steering system. Improper chassis maintenance will directly affect vehicle performance, stability, and safety. Therefore, chassis maintenance must be meticulous and systematic.

Crawler-type dump trucks are extremely common in small and medium-sized engineering projects. Their ease of use significantly improves work efficiency, but their frequent use also necessitates regular maintenance. One of the common problems is leakage in the hydraulic pump station. The hydraulic pump station is a core component of the crawler-type dump truck's hydraulic system, converting mechanical energy into hydraulic energy to drive various hydraulic actuators. When the hydraulic pump station leaks, it can lead to decreased equipment performance, energy waste, and even equipment failure. To ensure the normal operation of the equipment, operators must promptly identify and address hydraulic pump station leaks. This article will describe common methods for handling hydraulic pump station leaks from the perspective of a maintenance engineer.

Tracked dump trucks are important agricultural machinery, and the performance of their hydraulic system directly affects the overall working efficiency and service life of the machine. The hydraulic pump station, as the core component of the hydraulic system, is responsible for providing high-pressure hydraulic oil. Therefore, the maintenance and upkeep of the hydraulic pump station are crucial. This article, from the perspective of a tracked dump truck maintenance engineer, will detail the daily maintenance, inspection items, and solutions to common faults of the hydraulic pump station.

Wheeled dump trucks, as core equipment in engineering machinery transportation operations, operate in complex environments with significant load variations, placing extremely high demands on their tires and braking systems. These two systems not only affect vehicle work efficiency but also directly relate to driving safety and cost control. As maintenance engineers, it is essential to systematically master the daily inspection, maintenance procedures, and fault prevention measures for tires and braking systems to ensure stable and reliable vehicle operation.

Mini dump trucks (mini tipper) are suitable for narrow construction sites, early-stage earthwork for multi-story buildings, and small-scale landscaping and municipal projects due to their small size, high maneuverability, and moderate load capacity. In modern urban construction, the demand for material transportation in basement construction, old city renovation, and confined spaces is increasing. However, due to their high center of gravity, narrow track gauge, and limited visibility, they also pose unique accident risks in narrow and complex construction site environments (rollover, collision, crushing, and exhaust fumes causing suffocation). Mini dump trucks, with their compact size (typically around 2 meters in height), agile maneuverability (turning radius as low as 4.8 meters), and load capacity comparable to larger vehicles, have become crucial equipment in these specific scenarios.

In mining operations, especially in open-pit mines, small mines, or within mining areas, the efficiency and reliability of dump trucks for short-distance material transportation (e.g., ore, waste rock, soil, tailings) directly impact overall operating costs and production efficiency. The selection of engineering equipment directly affects production efficiency, cost, equipment lifespan, and safety.

Dump trucks, as important transportation equipment in engineering machinery, are widely used in construction, mining, ports, and some factories. However, the operating environment of dump trucks under different climatic conditions has varying impacts on their performance and safety. In extreme high or cold weather, drivers and maintenance personnel need to pay special attention to the operation and maintenance of dump trucks to ensure that the equipment operates efficiently and safely.

On construction sites, in mining, construction, agriculture, and forestry, construction vehicles are often used in these environments. Wheel dump trucks, tracked tippers, and tracked turners often undertake critical tasks such as loading, transporting, unloading, and turning materials. These vehicles operate in harsh environments, experience large fluctuations in loads, and have complex structures. Improper maintenance can easily lead to breakdowns and shorten their lifespan. Therefore, to extend the lifespan of these construction vehicles, regular maintenance is essential to minimize breakdowns. This article systematically summarizes and outlines key maintenance points for these two types of unloading/turning equipment from multiple perspectives for reference by equipment managers, maintenance technicians, and field operators.
