Принцип работы и структура
High torque rotary cylinders convert hydraulic pressure into rotational motion. Pressurized oil enters internal chambers and acts on pistons or vanes connected to a central shaft. This force creates controlled torque that rotates the output shaft. The structure includes a heavy-duty housing, precision-machined internal components, reinforced bearings, and advanced sealing systems designed to maintain performance in continuous port operations.
Основные преимущества
1. High Torque Output
Delivers up to 130000 Nm of torque, enabling reliable operation of large port cranes and heavy loading equipment under continuous use.
2. Strong Corrosion Resistance
Marine-grade coatings and seals protect against saltwater, moisture, and harsh coastal conditions, extending service life.
3. Точное угловое управление
Provides accurate positioning for hatch covers, loading arms, and crane operations, improving safety and efficiency.
4. Robust Construction for Continuous Duty
Reinforced components withstand vibration, shock loads, and long operating hours typical in busy ports.
5. Low Maintenance Requirements
Advanced sealing technology and durable materials reduce downtime and maintenance costs in port operations.
6. Flexible Customization
EVER POWER can customize torque, rotation angle, mounting style, and sealing systems to match specific equipment designs.
