3CX Construction Backhoe Loader

The 3CX Construction Backhoe Loader from Qingzhou Mingxu Supply Chain is a multi-purpose digging and loading unit for municipal, agricultural, and general construction work. It combines front-end loading, rear excavation, bulldozing, and ditching functions in one machine, reducing the need for separate equipment on small and medium sites.

The machine is fitted with a hydraulic pilot control system and supports quick attachment changes for different tasks. It is available for bulk orders and overseas export, with configuration options that can be adjusted to match specific working conditions.

Basic Configuration

System Overview

The engine drives the hydraulic pump, which supplies oil to the travel, loading, and digging circuits. The control valves regulate the loader boom, backhoe arm, bucket, and stabilizer functions, allowing the operator to perform shoveling, digging, ditching, and leveling tasks with smooth composite movements. The hydraulic pilot system provides light and responsive control, suitable for operators with basic training.

Operating Procedure

1. Pre-operation inspection: Walk around the machine and check tire wear, hydraulic hose condition, and bucket tooth wear. Verify engine oil, diesel, and hydraulic oil levels. Test the parking brake, working lights, hydraulic outriggers, and emergency stop button.

2. Startup and mode switching: Fasten the seat belt. Rotate the seat forward to operate the loader. Insert the key and complete the electric self-check before starting the engine. Rotate the seat 180° backward to switch to backhoe pilot controls.

3. Shutdown procedure: Fully retract the digging arm and raise the outriggers. Lower the loader bucket to the ground. Let the engine idle for 3 minutes to cool the hydraulic and power systems. Turn off the engine, cut off main power, and lock the cab before leaving.

Design Features

1. Multi-functional integration. Loading, digging, bulldozing, and ditching are combined in a single machine, covering common earthmoving tasks without requiring additional equipment.

2. Compact site adaptability. The 180° swivel seat and smaller footprint allow operation in narrow lanes, farm plots, and confined work areas where full-size machines are difficult to use.

3. Stable hydraulic performance. The hydraulic pilot control delivers steady power and smooth composite movements, suitable for continuous daily operation.

4. Lower maintenance requirements. The design uses widely available parts and simple service procedures, which helps reduce downtime and repair expense.

5. Bulk supply and customization. The model is available for full-container export and large-volume orders. Configuration and attachments can be adjusted for specific markets.

Shared Parts and Service Access

The 3CX Construction Backhoe Loader is assembled with a parts-sharing approach across its major sections. Hydraulic cylinders, control valves, pins, and seals are specified to common sizes, which means fleet owners and rental yards can keep fewer spare part types in stock. Bucket teeth, bushings, and hoses are compatible with several other machines in the same class, so replacement items are easier to source locally.

Lubrication points are positioned on the outside of the loader arms, backhoe pivot, and stabilizer legs, allowing daily greasing without removing covers. The engine compartment opens from the side for oil and filter checks, and the hydraulic tank has a sight gauge for fluid level checks. Electrical wiring is routed in protective sleeves with weather-resistant connectors to reduce faults in wet or dusty conditions.

This design keeps routine service tasks within reach of a single operator and avoids the need for specialized tools or factory support for common replacements. The same machine can be used for municipal trenching, farm work, and small quarry jobs by changing the front or rear attachment through a standard mounting interface, reducing the number of dedicated machines a contractor needs.

Typical Applications

1. Municipal pipeline and road work: pavement repair, drainage and cable trenching, sidewalk leveling, and debris transport; the compact size works well in older urban areas with narrow streets.

2. Rural and urban infrastructure: house foundation digging, irrigation channel construction, rural road widening, and backfilling for small projects.

3. Agriculture and livestock operations: orchard trenching, feed handling, manure cleaning, and farmland preparation.

4. Landscaping and green space maintenance: tree pit digging, slope shaping, green waste removal, and small water channel cleaning.

5. Sand and aggregate yards: loading and stockpiling of sand and stone, short-distance transfer, and yard leveling.

6. Small-scale mining and tunneling support: shallow excavation, residue clearing, and internal material movement.

7. Equipment rental use: suitable for short-term jobs on small and medium sites; one unit can replace two separate machines, lowering transport and operating cost.

8. Emergency and recovery tasks: landslide backfilling, ditch dredging after flooding, and road obstruction removal.

Warranty and Support

The complete unit is covered for 12 months or 1,000 working hours, whichever occurs first. Major assemblies such as the engine, main hydraulic pump, and transmission are covered for 6 months. Failures caused by manufacturing defects are repaired free of charge using original parts. Damage resulting from improper operation, overloading, or missed maintenance is subject to parts cost only. Freight and labor for replacement are the customer's responsibility. Wear items are outside the free warranty.
