Hydraulic Suspension Cylinder for Mobile Cranes

A mobile crane hydraulic suspension cylinder is a type of hydraulic cylinder used in the suspension system of a mobile crane. It plays a crucial role in providing support, stability, and adjustability to the crane’s suspension, allowing it to adapt to various load conditions and terrain. 

Here’s an overview of the hydraulic suspension cylinder in a mobile crane:

  1. Function: The hydraulic suspension cylinder is responsible for adjusting the suspension height and stiffness of the mobile crane. It helps absorb shocks, vibrations, and unevenness in the terrain, providing a smoother ride and enhancing the stability of the crane during transportation and lifting operations.

  2. Hydraulic System: The hydraulic suspension cylinder is part of the crane’s hydraulic system, which includes a hydraulic pump, reservoir, control valves, and hydraulic lines. The hydraulic pump pressurizes hydraulic fluid, typically oil or specialized hydraulic fluid, which is then directed to the suspension cylinder for adjustment.

  3. Cylinder Design: The hydraulic suspension cylinder is usually a double-acting hydraulic cylinder. It consists of a cylindrical tube, a piston, and a piston rod. The piston divides the cylinder into 2 chambers, allowing hydraulic fluid to act on both sides of the piston to extend or retract the cylinder.

  4. Suspension Adjustment: The hydraulic suspension cylinder is connected to the crane’s suspension system, typically at multiple points. By adjusting the hydraulic pressure and flow to the cylinder, the suspension height and stiffness can be modified. This allows the crane’s suspension to be raised or lowered, adapting to the load weight, ground conditions, and specific requirements.

  5. Control and Operation: The hydraulic suspension cylinder is controlled by the crane operator through the crane’s control system. The operator can activate the hydraulic valves or switches to adjust the suspension height and stiffness. This enables the crane to maintain proper ground clearance, optimize stability, and enhance overall performance during transportation and lifting operations.

  6. Load Distribution: The hydraulic suspension cylinder helps distribute the crane’s load evenly across multiple axles. By adjusting the suspension height, it ensures that the weight is properly distributed, minimizing stress on individual axles and tires. This improves the crane’s stability, maneuverability, and tire longevity.

  7. Maintenance and Inspection: Regular maintenance and inspection of the hydraulic suspension cylinder and the entire hydraulic system are essential for safe and reliable crane operation. This includes checking for leaks, ensuring proper lubrication, inspecting seals, connections, and hydraulic lines, and following the manufacturer’s recommended maintenance schedule and guidelines.

This is particularly important in commercial vehicles, where long hours on the road can cause driver fatigue and discomfort.

  2. Stability and Handling: Hydraulic suspension cylinders help maintain stability and control of the vehicle, especially during cornering, braking, and acceleration. By adjusting the suspension height and stiffness, the cylinders optimize the vehicle’s weight distribution, ensuring better traction and minimizing body roll. This enhances handling characteristics, making the vehicle more stable and maneuverable.

  3. Load Carrying Capacity: Hydraulic suspension cylinders are often used in vehicles designed for heavy loads, such as trucks and trailers. These cylinders allow for dynamic load leveling, where the suspension automatically adjusts to compensate for changes in load weight. This ensures that the vehicle remains level, improves stability, and prevents excessive strain on the chassis and tires.

  4. Adaptability to Terrain: Vehicles equipped with hydraulic suspension cylinders can adapt to different terrains and road conditions. By adjusting the suspension height, the cylinders provide increased ground clearance when traversing rough or off-road surfaces. This capability is particularly important in industries like agriculture, construction, and mining, where vehicles often operate in challenging environments.

  5. Safety and Control: Hydraulic suspension cylinders contribute to overall vehicle safety by improving braking performance and preventing wheel lock-up. They help maintain tire contact with the road surface, maximizing grip and reducing stopping distances. Additionally, by minimizing body roll and maintaining stability, hydraulic suspension cylinders enhance the vehicle’s ability to avoid obstacles and maintain control in emergency situations.

  6. Adjustable Suspension: Many hydraulic suspension systems offer adjustable features, allowing the driver or operator to customize the suspension settings based on specific needs or preferences. This includes adjusting the suspension height, stiffness, and damping characteristics. Such adjustability ensures optimal performance, comfort, and safety in various driving conditions or specific operational requirements.

  7. Component Protection: Hydraulic suspension cylinders also help protect other vehicle components, such as the chassis, axles, tires, and cargo. By absorbing shocks and vibrations, they reduce the stress and impact on these components, prolonging their service life and minimizing maintenance and repair costs.

Can rotary cylinders be used for both rotary motion and linear motion?

No, rotary cylinders are specifically designed for generating rotary motion and are not typically used for linear motion. Here’s a detailed explanation:

Rotary Motion:

Rotary cylinders, also known as rotary actuators, are primarily used to convert fluid power into rotational motion. They are designed to generate torque and rotate around a central axis. The rotational movement can be in a full 360-degree rotation or limited to a specific angle depending on the application and the design of the cylinder.

Linear Motion:

For linear motion, a different type of actuator, such as linear cylinders or linear actuators, is used. Linear cylinders are specifically designed to generate linear motion by extending or retracting a piston rod in a linear path. These actuators are commonly used in applications where straight-line movement is required, such as pushing, pulling, lifting, or sliding objects.


The design and internal mechanism of rotary cylinders are optimized for rotational motion, while linear cylinders are designed to provide linear motion. These two types of actuators have different structures and operating principles to fulfill their respective purposes.

While rotary cylinders cannot directly produce linear motion, they can be part of a system that combines both rotary and linear motion. For example, in some applications, a rotary cylinder can be used to generate rotational motion, which is then converted into linear motion using additional mechanisms such as racks, gears, or linkages.

It’s important to choose the appropriate type of actuator based on the desired motion requirements of the specific application. Manufacturers’ documentation and guidelines should be consulted to determine the most suitable actuator for a particular motion requirement.
