used Backhoe Excavator for sale

 CB 3CX is a classic "two-end busy" (excavator loader) produced by JCB in the UK, famous for its versatility, efficient operation capability and engineering adaptability. The following is a systematic description from three aspects: core design, performance parameters and application characteristics:

⚙️ 1. Core design: dual-end collaborative operation structure

Dual-function integrated structure

Front-end loading end: equipped with a general bucket (1.0~1.1m³) or a six-in-one multi-function bucket (1.0m³), supporting loading, bulldozing, clamping and other tasks, with a maximum unloading height of 2740mm, an unloading distance of 830mm, and a bucket angle of 4°.

Rear-end backhoe end: optional standard bucket (0.06~0.3m³) or deep section bucket (0.09~0.48m³), the excavation direction is backward, suitable for operations below the parking surface such as ditch excavation.

Chassis and drive system

Four-wheel drive, front wheel size 12.5×18, rear wheel 18.4×26, minimum steering diameter 6.9m (without brakes).

Italian CARRARO gearbox, 4-speed synchronous shifting, maximum speed 34.8km/h, taking into account both off-road and road mobility.

3. Application scenarios and derivative model features

Advantages of civil engineering

Multi-scenario adaptation: suitable for municipal pipeline laying, construction foundation pit excavation, farmland water conservancy and material handling, one machine replaces loader + excavator.

Attachment expandability: hydraulic hammers, forks, sweepers and other accessories can be quickly replaced to improve functional diversity.

Military enhanced version

Adapt to -40℃ extreme cold or 1.5m wading environment, standard bulletproof/explosion-proof cab, support ammunition storage and winch installation.

Can be hoisted by CH-47 helicopter or airdropped by C-130 transport aircraft to meet battlefield engineering needs 34.

Market positioning and reliability

JCB accounts for 33% of the global two-end market share. The 3CX series is positioned as high-end, and the cab comfort is comparable to Mercedes-Benz cars. The price is about 10% higher than that of competing products.
