(1) Triple safety locking design
Hydraulic locking: Equipped with dual hydraulic control one-way valves, it locks the position of the oil cylinder in case of pressure loss, with a locking error of ≤ 0.5mm (10 meter stroke);
Mechanical locking: optional mechanical pin structure, with a locking force of ≥ 120% of the rated load when carrying;
Pressure sensing locking: When the system pressure fluctuates by more than 10%, the backup seal compensation is automatically triggered to maintain the pressure holding state.
(2) Anti impact dynamic response
The valve core adopts a conical surface+damping hole structure, with an impact pressure attenuation rate of ≥ 40% (such as during emergency stop of high-altitude operation vehicles);
Equipped with a built-in buffer valve group, the speed fluctuation during lifting start stop is ≤ ± 5% to avoid load shaking (typical application: leveling of lifting equipment for port cranes).
(3) Long life sealing technology
The main seal adopts a polyurethane+metal skeleton composite structure, with a wear resistance of ≥ 100000 times (50 lifts per day can be used for 5 years);
Dust seal labyrinth design (protection level IP67), blocking more than 99% of dust intrusion, suitable for harsh working conditions such as mining and metallurgy.
(4) Intelligent integrated design
Integrated pressure sensor (accuracy ± 0.5% FS) and displacement feedback module, real-time monitoring of lifting status;
Support CANopen bus communication, remote adjustment of lifting speed (adjustable from 0.1-5m/min) and pressure threshold.
(5) Adaptability to all operating conditions
Temperature resistance -40 ℃~+80 ℃, response time ≤ 50ms in -20 ℃ environment;
The anti vibration performance reaches 50Hz and 50g acceleration (ISO 16750 standard), suitable for bumpy scenarios of construction machinery.
