One Machine for Multiple :Gates It travels horizontally along rails, enabling a single unit to operate multiple gates and cut equipment investment costs.
Multiple Safety Protections : Overload protection and upper/lower travel limit devices are equipped to avoid equipment damage caused by overload and over-travel.
Variable-Frequency Travel Mechanism :The traveling trolley adopts variable frequency speed regulation, delivering shock-free start & stop and high-precision positioning when docking at gate bays.
Dual Driving Modes : Electric operation for daily use, plus integrated manual emergency mechanism to guarantee operation under power failure.


Complete Specification Range :Full series of lifting force grades available, compatible with small, medium and large hydraulic gates of all types.
Heavy Anti-Corrosion Frame : Integral steel structure with high rigidity, resistant to outdoor moisture and rain corrosion.
Dual Control Modes :Supports local on-site operation and remote electric control for flexible and convenient manipulation.
Multi-Function Operation :Apart from gate lifting, it can also hoist trash racks and small hydraulic structural components.
Reliable Travel Braking :Equipped with travel locking brakes to prevent trolley sliding after stop and ensure stable positioning.
