• Main Structure: Consists of an excavator, loader, hydraulic system, cab, and powertrain. The front-end loader is typically a six-link, counter-rotating linkage or an eight-link, enabling digging and loading operations. The rear-end excavator, consisting of a boom, arm, and bucket, is used for excavation. The hydraulic system is the core of power transmission, with the loading and excavation hydraulic systems connected in series and in parallel with the steering hydraulic system. A diesel engine is typically used to power the entire machine.

Core Features of Backhoe Loaders (Two-Purpose Machines)
1. Dual-Purpose, Integrated Functionality: Capable of both front-end loading and back-end excavation, this machine eliminates the need for frequent equipment changes, effectively acting as a "loader + excavator" combination, significantly enhancing operational flexibility.
2. Highly Adaptable, Wide Range of Applications: Its relatively compact size allows it to operate in confined spaces (such as municipal projects, small construction sites, and farms), accommodating a variety of tasks, including earthmoving, trench excavation, and material loading and unloading.
3. Efficient and Flexible, Convenient Transferability: It eliminates the need for disassembly and transportation, allowing for self-transfer and rapid job switching. It is particularly suitable for small and medium-sized projects or those with multiple processes, reducing equipment investment costs.
Key Performance Parameters
• Digging Performance: Core indicators include maximum digging depth (typically 3-5 meters) and digging force, which determine its earthbreaking and excavation capabilities.
• Loading Performance: Key indicators include rated load capacity (typically 1-3 tons) and bucket capacity, which influence material loading and unloading efficiency.
• Power and Control: Equipped with a medium-to-high-power diesel engine (typically 40-100kW) and a hydraulic control system, these vehicles offer precise and smooth movements. Some models also support four-wheel drive, providing excellent off-road performance.
• Driving Performance: These vehicles are roadworthy, with a typical speed of 15-30km/h, meeting short-distance travel requirements.

FAQ
• What to do if hydraulic oil leaks?: Leaks may be caused by worn seals, loose pipe joints, or broken oil pipes. To address this, regularly inspect and replace seals, ensure pipe connections are tight, and promptly replace damaged oil pipes.
• Causes and solutions for hydraulic pump anomalies: Symptoms such as weak operation or excessive noise are usually caused by wear inside the pump, a clogged oil inlet, or poor hydraulic oil quality. Regularly changing the hydraulic oil, cleaning the filter, and checking the pump's condition can effectively prevent and resolve this issue.
