The YW388 backhoe loader features front and rear wheel steering, with a robust monocoque frame offering exceptional off-road capability and traction recovery. Powered by a Yuchai 4105 turbocharged engine at the front, the newly designed cab offers ample space, excellent visibility, and superior comfort. This ensures a pleasant working environment during your tasks, minimising fatigue. The excavator itself is a 75-tonne model with a digging depth of 4 metres. This versatile backhoe loader excels at both earthmoving and loading operations, making it an invaluable asset for landscaping and construction projects.

High-strength structure and performance as well as reliable hydraulic systems enable this complete machine to realize wide digging range, lifting and digging forces.
The curved loadings movable arm and unique mechanism of connecting rod provide the complete machine with preferable loading distance and translational compatibility and enable the loading operations to be simpler and quicker, reducing the splash and falling of materials.
The foundation support of the digging movable arm is wide and becomes narrower gradually, which expand the range of vision, the small- volume oil tank is fixed only with single pin, the line of sight of operators will not be affected when operating.
Unique mechanism of connecting rod of bucket enables the bucket to rotate by 180°, which simplifies the digging operation of vertical arm.
The selection and use of quick change couplers of work device make it possible to replace bucket and the other work devices quickly and easily without the use of any special pin shafts, tools or bucket.
Four-wheel drive improves the tractive force further.
Middle-position open type hydraulic system and heavy-duty tandem gear pump make the accurate measurement and portable and stable operation possible.
The driver's cab is advanced in the same trade with its wide visual field for operation.
Simple service and maintenance brings about great convenience for the user.

1. Urban Infrastructure Construction and Maintenance (Core Application Scenario)
This represents the most prevalent application for backhoe loaders, particularly within spatially constrained urban environments.
Road Repair and Maintenance:
Filling potholes, excavating kerbside drainage channels, burying or repairing underground utilities (e.g., emergency water pipe repairs, cable laying).
Landscaping: Digging tree pits, transplanting trees, laying turf, constructing landscape ditches.
Municipal works: Excavating foundations for street lamps, installing traffic sign posts, etc.
2. Construction and Building Works
Rural and low-rise construction: Such as excavating foundations for self-built houses, digging septic tanks, and indoor demolition.
Construction site auxiliary tasks: Clearing construction waste, levelling sites, short-distance earthmoving.
Pipework Installation: Trench excavation for water mains and gas pipelines (particularly in confined sites where large excavators cannot operate).
3. Agricultural and Rural Development
Its medium size and manoeuvrability make it highly suitable for agricultural applications.
Irrigation and Water Management: Excavating irrigation channels, river channel maintenance, fishpond dredging.
Land Preparation: Site levelling, excavation for greenhouse foundations.
Agricultural & Forestry Operations: Installation of pasture fencing, trenching for fertiliser application in orchards.
4. Emergency Response & Disaster Relief
Flood Defence: Construction of flood embankments, reinforcement of riverbanks.
Road Clearance: Debris removal following earthquakes or mudslides, winter snow clearance (with snowplough attachment).
5. Specialised Environment Operations
Confined Space Operations: Its tyre-based mobility and compact turning radius make it ideal for working in narrow areas inaccessible to larger excavators, such as alleyways, factory interiors, and backyards.
Road Construction: Subgrade compaction and excavation for rural roads and rudimentary pathways.
A:It is highly suitable for linear projects such as highways and railways, as well as land levelling in development zones. Its advantage lies in its ability to independently perform multiple tasks including excavation, loading, transport and levelling, thereby reducing equipment coordination. It proves particularly efficient on sites with diverse tasks but limited space.
A:Compared to single-function excavators or loaders, it demonstrates clear advantages in narrow spaces such as factory construction, pipeline laying, and landscaping renovations. Its dual functionality saves equipment manoeuvring space, allowing flexible role switching to swiftly complete various minor tasks.
A:Extremely so. It serves as an ideal choice for municipal departments, employed for tasks including roadside ditch excavation and desilting, trench digging and backfilling for cable conduits, verge trimming, and winter snow clearance. Its high manoeuvrability enables rapid response and handling of various emergency repair duties within urban environments.
A:Yes, it serves as vital emergency equipment. It is frequently deployed at disaster sites (such as mudslides or landslides) for rapid obstacle clearance, road clearance, excavation of drainage channels, and construction of temporary flood barriers. Its multifunctionality and high mobility aid in restoring critical lifelines.
