Simple & Reliable Structural Design: The core assembly consists of motor, reducer, drum, steel wire rope and other standard components. The mechanical transmission principle is straightforward with robust overall construction.
Wide Range of Lifting Capacity :Single-unit capacity ranges from 50KN to 7000KN (approx. 5 tons to 700 tons). Double-lifting-point models satisfy ultra-heavy load working conditions.
Adaptable to Various Lifting Heights: Standard units handle general lifting requirements; special high-lift models deliver lifting height over 18m, some up to 120m, ideal for special applications such as deep-hole gates.
Flexible Lifting Point Layout :Single and double lifting point options are available. Double-point models run synchronously via connecting shafts with adjustable center distance between lifting points, suitable for large-span flat and radial gates.
Customizable Lifting Speed :Normal lifting speed: 1.3–3m/min. QPK rapid-closing models feature adjustable emergency closing speed, with speed limited below 5m/min when approaching the gate sill.


Complete Safety Protection System :Standard travel limit switches avoid over-travel operation; hydraulic or electromagnetic brakes and other safety fittings ensure reliable braking when halted.
Multiple Operation Modes :Manual, electric and remote PLC control are supported. Models below 400KN can be fitted with hand cranks for normal operation during power outages.
Strong Site Adaptability for Installation:Fixed-type units for permanent installation; trolley-type units are mobile and mountable on pier tops and other sites. Small-sized models feature extremely easy installation.
Compatible with Multiple Hydraulic: Equipment Suitable for operation of flat gates, radial gates, trash racks and other facilities.
Interlock Function for Local & Remote Control: Functional interlock between local and remote operating systems prevents misoperation, securing safe normal operation and emergency handling.
Serialized Product Models: Multiple series including QPQ (standard fixed type), QPK (rapid gate-closing type), QPG (high-lift type), QPT (trolley type) to match diverse engineering demands.
