III. Dimensions, Material & Design Concept
Cargo Box Dimensions (L×W×H): 6100 × 2420 × 550 mm (20.0 × 7.94 × 1.8 feet). This spacious cargo bed or flatbed can be configured as a hydraulic telescopic cargo box.
Chassis Frame: 273 mm (10.75 inches) High-Strength Steel (Double layer with partial three-layer reinforcement). This heavy-duty truck frame is built for extreme loads.
Design Philosophy: "Foundation for Performance." The vehicle's core strength lies in its chassis frame, formed by a single 6300-ton press stamping. This process creates a warp-resistant, high-load-bearing foundation. The design incorporates intelligent features like the EBP power switch and a unique floating three-point bridge structure to actively reduce stress and optimize efficiency during both travel and lifting operations. The Mulang M3 cab features a "Dragon Bone Frame" and four-point spring suspension for comfort and safety.
Primary Material: High-strength alloy steel is used throughout the chassis frame and the crane's hexagonal boom sections to maximize the strength-to-weight ratio and ensure long-term durability.
IV. Detailed Component Advantages
Robust Chassis & Cab: The Mulang M3 chassis features a "Dragon Bone Frame" cab structure for superior impact protection. The 10.75-inch reinforced frame provides an exceptionally stable platform for the heavy-duty crane. The cab itself is a "full-floating" design with four-point spring suspension, dramatically reducing vibration and driver fatigue. Its spacious flat-floor design and optimized seat enhance long-hour comfort.
Efficient Powertrain: The Yuchai engine is equipped with an EBP switch (Economy, Balance, Power). This intelligent system allows the driver to actively select between light, medium, and heavy load modes, optimizing engine output for fuel savings of up to 6%. The Fast 8-speed transmission provides the precise torque control and gear range needed for both highway travel and demanding crane operations. The power take-off (PTO) is factory-installed for seamless integration.
Durable Running Gear: The 153 reinforced rear axle is engineered to handle the dynamic stresses of lifting and heavy transport. Safety is ensured by a dual-circuit air brake system with an energy-saving spring brake for fail-safe parking, supplemented by an Anti-lock Braking System (ABS).
Advanced Crane Structure: The XCMG crane utilizes a high-strength hexagonal boom section, which offers superior resistance to bending and torsion compared to traditional shapes. Its single-cylinder telescoping mechanism with cable synchronization ensures smooth, efficient, and reliable boom extension. An integral anti-sway control and rotation buffer device protects the swing gear from impact during travel, enhancing overall vehicle safety and making lifting operations more secure.
V. Key Features & Chengli Group Advantages
Versatile & Predictable Lifting: The crane delivers precise, powerful lifting across its operating range. At its maximum 36-foot extension, it handles 1,323 lbs, while at a close 8.2-foot radius, it leverages its full 13,889 lb capacity. This predictable performance, detailed in the provided load charts, allows for safe and efficient operation in tight spaces or at height, meeting diverse material handling needs.
Unmatched Stability: The hydraulic outrigger system provides a secure working base. The front circular hydraulic outriggers feature an adjustable span from 7.48 to 16.73 feet, allowing operators to stabilize the vehicle on uneven terrain. This wide stance, combined with the rigid chassis, ensures maximum safety during heavy lifts. Options like a hydraulic rear outrigger can be added.
