Proper sizing of high torque rotary cylinders is critical for safe and reliable operation in heavy load applications such as port cranes and industrial handling equipment.
Product Overview
High torque rotary cylinders from EVER POWER are widely used in port terminals, shipyards, and heavy industrial facilities. They are designed to handle substantial rotational loads while maintaining precise control.
Core advantages include strong torque output, robust construction for demanding conditions, precise angular control, and customization options to match specific heavy load requirements.
Technical Parameters
| Parameter | Specification |
|---|---|
| Maximum Torque Output | Up to 130000 Nm |
| Rotation Angle | 90 degree to 360 degree |
| Operating Pressure | Up to 210 bar |
| Operating Temperature | -20 degree C to +80 degree C |
| Mounting Options | Flange or foot mounting, custom available |
Working Principle and Structure
High torque rotary cylinders convert hydraulic pressure into rotational motion through internal pistons or vanes that drive a central shaft. The structure includes a heavy-duty housing, precision-machined components, reinforced bearings, and marine-grade sealing systems. Proper sizing ensures the cylinder can handle the required torque without excessive stress on components.
Core Advantages
1. Strong Torque Capacity
Designed to handle heavy rotational loads commonly found in port and industrial equipment.
2. Precise Angular Control
Provides accurate positioning even under heavy load conditions.
3. Robust Construction
Built to withstand continuous heavy loads and vibration in demanding environments.
4. Safety and Reliability
Properly sized cylinders reduce stress on components and improve operational safety.
5. Customization for Heavy Loads
Can be tailored in torque, angle, and mounting to match specific heavy load applications.
6. Long-Term Cost Efficiency
Correct sizing helps avoid premature wear and reduces long-term maintenance costs.
Structure and Material Craftsmanship
These cylinders use heavy-duty alloy steel housing with precision-machined internal components. High-strength bearings and marine-grade seals are essential for handling heavy loads. Proper sizing ensures the structure can manage the required torque without excessive stress on bearings and seals.
Typical Application Scenarios
Port Cranes
Used for rotating heavy loads during cargo handling. Correct sizing ensures stable torque delivery without overloading the cylinder.
Hatch Cover Systems
Requires reliable rotation under heavy loads. Proper sizing helps maintain performance and safety during operation.
Heavy Industrial Equipment
Applied in machinery that handles large rotational loads where accurate sizing is critical for safety and efficiency.
Selection Guide
When sizing a high torque rotary cylinder for heavy load applications, confirm the following:
- Maximum torque required including safety margin (typically 1.5x or higher)
- Required rotation angle
- Operating pressure of the hydraulic system
- Load characteristics (static vs dynamic loads)
- Environmental conditions (temperature, corrosion risk)
- Mounting method and structural support
- Expected duty cycle and continuous operation time
Correct sizing helps ensure safe operation and reduces the risk of premature failure under heavy loads.

Frequently Asked Questions
How do I calculate the required torque for heavy loads?
Calculate the maximum load moment and add a safety margin (commonly 1.5 times or higher) to account for dynamic conditions.
What happens if a cylinder is undersized?
Undersized cylinders can experience excessive stress, leading to premature wear, leakage, or failure under heavy loads.
Can oversizing cause problems?
Oversizing is generally safer but may increase cost and weight. Proper calculation helps find the right balance.
