II. Seven-Section Synchronous Telescopic Boom: High Strength and Precision Control

(1) Structural Design Innovation

The boom is constructed from 3-4mm high-strength steel (yield strength ≥690MPa), with an octagonal cross-section that increases rigidity by 40% and reduces self-weight by 18% compared to traditional hexagonal booms, with a wind resistance rating of level 10 (withstands 24m/s wind speed). The seven-section synchronous telescoping design achieves a positioning accuracy of ±5mm, ensuring high-altitude docking errors are less than 1cm.

The dual-cylinder redundant luffing system with double-acting balance valves ensures smooth and impact-free luffing. Even if one cylinder fails, the boom can still retract, improving reliability by 200%. The boom luffing angle ranges from 0° to 78°, covering all scenarios from horizontal extension to vertical lifting.

(2) Intelligent Control System

The operation modes are flexible, with a turntable seat equipped with a shock-absorbing seat and sunshade, integrated with a 7-inch LCD display for real-time monitoring of height, amplitude, and outrigger pressure. The basket supports wireless remote control within 100 meters, with an emergency stop button and a response time of <1 second to 突发情况 (emergencies). Ground electric control backup ensures stable operation in complex electromagnetic environments.

Imported electro-hydraulic proportional valve blocks enable stepless speed regulation, with an operating handle force of ≤8N and a linkage response time of <0.5 seconds for boom slewing, telescoping, and luffing, making it easy for novices to operate.

III. Dongfeng Chassis: Durability and Comfort

The YCY30165-60 engine uses turbocharging and intercooling technology, enabling cold starts without preheating at -25°C, with a 15% improvement in fuel efficiency and a fuel consumption of ≤18L per 100km. Matched with a 6-speed gearbox, it provides smooth power output, adapting to frequent start-stop conditions. Key chassis components such as the steering gear and drive shaft have passed 1 million kilometers of intensive testing, and the standard 650R16 steel wire tires have a tread life of 150,000 kilometers, effectively reducing full-life cycle costs.

(2) Humanized Cab

The flat-roof single-row cab accommodates 3 people, equipped with air conditioning, power windows, and 6-way adjustable ergonomic seats, reducing long-distance driving fatigue by 40%, with cab noise ≤78dB, better than the industry average. It also integrates a rear-view camera, blind spot monitoring radar, and automatically heated rear-view mirrors to ensure driving safety in rainy and foggy weather. The remote electronic throttle design allows operators to adjust engine speed at high altitudes, further improving operational efficiency.

IV. Safety System: Seven Layers of Protection for the Entire Operation

(1) Active Safety Technology

The intelligent interlock mechanism eliminates risks at the source: if the outriggers are not fully extended, the boom amplitude is automatically limited to within 12 meters; boom operation is locked during vehicle movement, and misoperations trigger audible-visual alarms (volume ≥85dB).

The dual amplitude/height sensors (accuracy ±0.1m) give pre-alarms 1 meter before critical values and automatically stop at limits. The vehicle-level inclinometer (accuracy ±0.5°) forcibly locks the boom when tilt limits are exceeded, effectively preventing rollover accidents.

(2) Passive Safety Configurations

The basket uses φ48×4mm high-strength steel guardrails (impact resistance ≥1200N), double-layer 25mm non-slip pattern aluminum plates (friction coefficient ≥0.7), and comes standard with two high-strength safety belts. Four yellow strobe lights on the body provide a nighttime warning distance of 200 meters.

The 200L hydraulic tank has a low-level alarm, and the electric emergency pump can lower the platform to the ground within 3 minutes. All 13 cylinders are integrated with double-acting hydraulic locks to quickly lock positions in case of sudden power outages, with a safety redundancy coefficient 2.5 times the national standard.

V. Cross-Industry Applications: All-Round Expert from Construction to Power

(1) Core Scenario Coverage

In super-high-rise construction, the 36-meter working height allows single-boom access for high-altitude curtain wall installation and fire pipeline laying, reducing reliance on tower cranes. In municipal engineering, the 20-meter working amplitude covers full bridge sections, combined with a 100km/h transfer speed, suitable for urban viaduct streetlight replacement and cross-river bridge inspection.

In power maintenance, the level 10 wind resistance design and hydraulic leveling function meet the needs of substation equipment maintenance and wind turbine tower cleaning, ensuring stable operation even on tilted towers. For warehousing and logistics, the compact body passes through automated warehouse gates, and the 360° basket rotation enables no-blind-spot maintenance of high-position shelves. In industrial installation, the 300kg load supports heavy tool operations, with ±5mm positioning accuracy ensuring precise work like anti-corrosion coating of chemical plant reaction towers and high-altitude assembly of large equipment.

(2) Extreme Condition Adaptation
