Loader-digger
product presentation
The excavator loader produced by Shandong Feister Machinery Co., Ltd. (commonly known as the "two-in-one machine") is a multifunctional engineering equipment that integrates the dual core functions of a container loader and an excavator. This single machine replaces multiple standalone units, significantly reducing equipment investment and labor costs. Featuring a four-wheel-drive design, it boasts a compact structure, flexible steering, and strong off-road capability, making it a direct competitor to classic models such as the JCB 3CXD and Caterpillar 420. It is suitable for a wide range of construction scenarios, including municipal projects, rural infrastructure development, road maintenance, agricultural water conservancy, factory site leveling, and landscaping. As a essential core equipment for small and medium-sized projects and leasing operations, it offers convenient relocation and high operational efficiency, earning the reputation of a "mobile construction team."

Core Product Advantages
Crawling Mode: Four wheels move synchronously laterally, achieving a horizontal displacement of 300–500 mm. This enables parallel movement without turning, effortlessly handling challenges such as "digging trenches near walls, unloading on narrow roads, and precise positioning at close ranges."
Four-wheel steering + Crab-Style Dual Mode: Supports seamless switching between conventional steering, four-wheel steering, and crab-style driving modes, with a minimum turning radius of ≤6m. This enables agile navigation through narrow tunnels and densely packed pipeline areas, increasing operational range by 40%.
Precision Control: Powered by an electronically controlled hydraulic system, the crab-like movement offset is precisely adjustable. Combined with pilot operation, it ensures error-free lateral material transfer and edge excavation, allowing even novice operators to quickly master the technique.
Front shovel function: 1.3–1.5 m³ enlarged bucket with a digging force of 38–45 kN, enabling rapid loading, pushing, and site leveling for materials such as sand, gravel, soil, and construction materials.
Backhoe function: Maximum excavation depth of 4.2–5.3 m (with optional telescopic arm), excavation force of 46–55 kN, supports side-shift excavation. When equipped with attachments such as a breaker hammer and wood grab, it can perform tasks including slotting, crushing, and lifting.
Multi-condition adaptation: Comprehensive coverage for various scenarios including municipal pipeline excavation, hutong renovation, rural housing foundation construction, factory equipment installation, and landscaping site preparation. No disassembly required during relocation, ensuring flexibility and efficiency.
Powertrain Core: Equipped with Weichai/Yuchai/Commins engines (72–93 kW), delivering robust performance without lagging under heavy loads, with fuel consumption as low as 12–15 L/h, ensuring both economy and environmental friendliness.
Overloaded chassis: All-wheel drive + reinforced drive axle, with a maximum traction force of 39–50 kN (optional reinforced version), enabling effortless navigation through complex terrains such as muddy roads, potholes, and mountain paths. The wear-resistant tires provide excellent grip.
Stable structure: Thickened steel plate body, reinforced upper and lower arms, H-shaped support legs + optimized center of gravity design, ensuring no tilting or side-to-side movement during excavation operations, and resistance to deformation during prolonged high-intensity use.
Luxury cab: Closed design with climate control, shock-absorbing swivel seats, and a large central touchscreen, offering an unobstructed view with no blind spots while effectively isolating noise and dust.
Convenient operation: Hydraulic pilot lever + one-touch control in crab-like mode ensures effortless operation with reduced fatigue during prolonged work; equipped with a reversing camera and safety guardrails to ensure operational safety.
Convenient maintenance: The cab can be folded forward, providing ample space for engine and hydraulic system inspections. Key components are from renowned brands, resulting in a low failure rate and easy availability of spare parts.
