Product Overview
Against the backdrop of rapid development in global smart logistics and cross-border trade, mobile container unloading vacuum tube gantry cranes have become an indispensable “efficiency-boosting tool” for modern warehousing centers, port transshipment stations, and e-commerce sorting centers.
Addressing the pain points of confined space, hot and stuffy environment, dense cargo stacking, and extremely high loading and unloading frequency within containers, this equipment completely rewrites the history of heavy-duty handling through the perfect combination of “vacuum power” and “omnidirectional mobile chassis.”
This product is a high-frequency, lightweight handling terminal specifically designed for containers (20/40-foot units) and vans. It revolutionizes the traditional conveyor belt + manual handling model, allowing operators to unload and stack hundreds of items per hour in a near-zero-gravity state.
Core Components
Intelligent Mobile Chassis: Lithium-ion battery driven, supporting 360° rotation or omnidirectional lateral movement.
Low Headroom Folding/Telescopic Arm: A multi-stage rigid arm optimized for a 2.3-meter height within the container, with an extension length of 6-8 meters.
Vacuum Lifting Tube: Utilizes air pressure difference for vertical power supply, offering extremely high sensitivity.
Multi-functional End Effector: A suction cup array that allows for rapid switching between different packaging types, such as cartons, woven bags, and paint buckets.
Working Principle
The core of this equipment lies in the linear lifting force generated by the air pressure difference.
The operator adjusts the vacuum level via an ergonomic handle:
1. Inhale/Lift: Decrease the pressure inside the tube; the lifting tube automatically retracts, lifting the goods.
2. Release/Lower: Increase the pressure inside the tube; the lifting tube extends under gravity, lowering the goods.

Product Leading Technology Highlights
1. Embossed Intelligent Center of Gravity Adaptation
The 2026 model integrates an embossed intelligent force control algorithm. When gripping irregularly shaped items with a shifted center of gravity (such as partially filled woven bags), the system automatically fine-tunes the local pressure distribution within the suction cups to ensure the goods remain vertical during handling, effectively preventing slippage.
2. 3D Vision-Assisted Alignment
The end effector is equipped with a lightweight RGB-D camera. In low-light conditions deep inside containers, the system automatically scans the stacked outline ahead and marks the optimal gripping position on the handle display, even assisting in “one-click alignment.”
3. 5G-Advanced Digital Logistics
Based on 5G-Advanced communication, the equipment is interconnected with the warehouse WMS system in real time. The weight, dimensions, and operation time of each unloaded item are recorded, enabling transparent digital management of the logistics chain.
Application Value
1.Labor Liberation: Completely frees porters from strenuous bending and lifting movements, aligning with the latest ESG corporate social responsibility guidelines.
2.Zero Surface Damage: Compared to traditional claw grippers, vacuum adsorption causes no compression or snagging on the carton surface, making it particularly suitable for the damage-free loading and unloading of high-end appliances and fresh produce.
3.Flexible Deployment: The mobile design means no modifications to existing loading docks or conveyor belt systems are required; a single unit can be flexibly deployed across multiple unloading points.
