   • Smooth Lifting and Lowering: The hydraulic system provides smooth, precise lifting and lowering movements, avoiding the shocks and vibrations that mechanical transmissions might cause, which is beneficial for protecting both the load and the equipment itself.
   • High Load Capacity: Despite their compact size, they can easily lift hundreds of kilograms or even several tons of heavy objects thanks to the powerful thrust of the hydraulic system.
   • Energy-Efficient and Environmentally Friendly: Being electrically powered, they produce no exhaust emissions and low noise compared to fuel-powered equipment, aligning better with environmental requirements and making them suitable for indoor operations.
2. Excellent Mobility and Flexibility:
   • Electric Walking (Electric Drive): Equipped with an electrically driven walking system, allowing the user to control its movement (forward, backward, turning) freely on flat ground via a handle or remote control without strenuous pushing or pulling, significantly reducing operator fatigue.
   • Compact and Agile: The overall compact design occupies minimal space, enabling it to easily maneuver through narrow passages, workshops, warehouses, or production lines.
   • Easy to Transport: Some models are foldable or detachable, facilitating transportation and storage.
   • Quick Deployment: No complex installation required; it’s ready to use when stopped, greatly saving preparation time for operations.
3. Multi-functional Telescopic Boom Design:
   • Three-section Telescopic Boom: This is a key feature of this type of crane. The boom can extend in multiple sections (e.g., three sections), meaning it can achieve greater lifting height and a longer working radius while maintaining the equipment’s compactness. This increases the coverage and flexibility of lifting operations.
   • Rotary Function: The lifting arm (or the entire upper structure) can rotate to a certain angle, or even 360 degrees. This allows the crane to pick up, move, and place materials within a larger range from a fixed position without frequently moving the entire machine, greatly improving operational efficiency and convenience.
4. Intelligent and Convenient Operation:
   • Remote Control Operation: Advanced models are equipped with wireless remote controls, allowing operators to precisely control the crane from a safe distance, including lifting, telescoping, rotating, and walking movements.
