Boom lifts (mainly including articulated boom and telescopic boom types) are widely used in high-altitude operations in municipal, power, transportation, and firefighting sectors due to their flexible operation and strong obstacle-crossing capabilities. Their structural design integrates mechanical, hydraulic, and electronic control technologies, with core features reflected in the following aspects:
Multi-section Articulated Boom Structure: Boom lifts employ a multi-section folding or telescopic boom design, using hydraulic cylinders to drive the boom's deployment, luffing, and extension. Articulated boom lifts have a "Z"-shaped folding boom, enabling them to perform suspended operations over obstacles; telescopic boom lifts use single or multi-section linear telescopic booms, achieving higher working heights (e.g., over 45 meters), suitable for vertical operations in open spaces.
Fully Hydraulic Drive System: The hydraulic system is the power core of the boom lift, consisting of a hydraulic pump, control valve assembly, hydraulic cylinders, and oil circuits. The hydraulic pump converts mechanical energy into hydraulic energy, and a load-sensitive system precisely distributes the flow to control boom lifting, slewing, and platform leveling, ensuring smooth operation and responsiveness. Some models employ electro-hydraulic proportional control technology for stepless speed regulation and energy-saving operation.
Integrated Dedicated Chassis and Travel Capability: Utilizing a fully hydraulic self-propelled dedicated chassis, it overcomes the limitations of traditional modified chassis, enabling loaded travel. The chassis primarily features an H-shaped variable cross-section composite box girder structure, paired with high-load solid rubber tires or off-road tracks, enhancing overall rigidity and terrain adaptability. A large-angle backward-tilting hinge design optimizes the center of gravity distribution, and the counterweight module effectively balances working torque, ensuring stability during travel and operation.
Three-Dimensional Rotation and Automatic Leveling Device: The turntable supports 360° continuous rotation, and the work platform automatically maintains a level position (automatic leveling), ensuring operator safety and operational accuracy even during boom luffing. Some high-end models are equipped with ground wireless remote control, dual control system (valve control + pump control) and T-BOX remote fault diagnosis system to improve the level of intelligence.
