Product Description

Product Advantages
1. The system employs advanced microprocessor technology and an embedded operating system. It features a compact design, user-friendly interface, strong scalability, low power consumption, powerful functionality, high sensitivity, and ease of operation.
2. It has a large dot-matrix screen with backlighting for temperature control, displaying graphics, actual lifting weight, rated lifting capacity, outreach, boom length, and angle.
3. It offers comprehensive pre-alarm, overload alarm, and overload control output functions. The system also includes thorough self-diagnostic capabilities and Chinese fault display, providing effective guidance for troubleshooting.
4. Its unique crane working angle limitation function ensures reliable operation under complex conditions; it also has an overload memory function (black box).
5. The crane boom uses fully optimized octagonal cross-sections, effectively reducing lateral sway, making operations safer. High-strength wear-resistant steel plates are used, ensuring even force distribution, lighter weight, and extremely high reliability and safety during hoisting. The crane's auxiliary boom is independently designed domestically for the first time, featuring forward and backward angle compensation arms, ensuring seamless support for every hoisting task.
6. The remote controller saves human resources: one person can handle operation, rigging, and hooking without the need for a signalman, improving work efficiency. Since the operator controls the crane from the ground and independently judges its operational status, the accuracy and continuity of the operation have significantly improved compared to before.
The first boom adopts a double-cylinder structure, achieving the highest international level of main design parameters for cranes, with the entire vehicle height controlled at 3.3 meters or within 3.5 meters. The crane's telescopic arm is the first domestically to use a dual-cylinder dual-pushing design, providing exceptional load-bearing telescoping capability, safety, and stability during extension. The hook is equipped with an anti-disengagement device that uses the principle of gravity levers, making it easier to handle rigging. The metal structure has high strength and durability. The slewing support uses a double-chain eight-point contact slewing support, with a double-row ball turntable bearing capable of simultaneously withstanding radial force, axial force, and overturning moments due to having two rows of steel balls. To accommodate different force ratios, the contact angle varies from very small to 90 degrees. When the distribution circle diameter of the steel balls is the same, the total load-bearing capacity of each row of steel balls is directly proportional to the selected steel ball diameter. Therefore, under the same support section height, when simultaneously bearing axial force and overturning moments, double-row ball bearings can better utilize the section dimensions. The rotary mechanism uses high-quality slewing supports and reducers, making the operation process smoother and more stable, allowing the crane to achieve full 360-degree rotation, which is flexible and convenient, significantly improving work efficiency! The hydraulic slewing drive motor uses top-tier domestic hydraulic motors, featuring extremely high mechanical and volumetric efficiency, as well as excellent impact resistance and high load-bearing capacity. The hydraulic slewing drive system is equipped with bidirectional balancing and bidirectional overload protection valves, ensuring smooth and safe slewing start-up and control, providing even smoother and safer micro-motion slewing. H-type outriggers with built-in oil pipes offer an aesthetically pleasing appearance. The H-type outriggers have a large extension distance, with each leg having both horizontal and vertical cylinders for independent adjustment. The H-type outriggers adapt well to various working sites and ground conditions, making leveling easy, offering high support heights, large spans, and increased lifting support area, enhancing stability during heavy-lift operations. To ensure sufficient extension distance, the fixed beams of the left and right outriggers are staggered front to back. The folding-arm crane is equipped with a hoist system to compensate for its shortcomings in operational environments, making it more versatile and flexible. This allows the folding-arm crane to perform tasks such as deep-well operations, deep-well rescue across workshops, long-distance emergency response, and long-distance towing...
