4kg 12MPa Hydraulic Steering Cylinder for Scissor Fork Type Aerial Work Vehicle

In scissor fork-type aerial work vehicles, the steering system is responsible for controlling the car's direction. While scissor lifts typically do not have traditional steering mechanisms like those found in automobiles, they may utilize various steering systems to achieve maneuverability. However, it's important to note that the steering mechanisms in scissor fork-type aerial work vehicles can vary depending on the specific design and manufacturer. Some scissor lifts may employ hydraulic steering cylinders to enable steering movements. 

Here's a general overview of how hydraulic steering cylinders may be utilized in scissor fork-type aerial work vehicles:

1. Hydraulic System: The hydraulic system in the scissor lift includes a hydraulic pump, reservoir, control valves, and hydraulic cylinders. The hydraulic pump pressurizes the hydraulic fluid (usually oil) and stores it in the pool. The control valves regulate the flow and direction of the hydraulic fluid to the cylinders.

2. Cylinder Configuration: Steering cylinders, if present, are typically mounted in the steering mechanism of the scissor lift. The number and configuration of the steering cylinders depend on the specific design and requirements of the vehicle.

3. Steering Operation: When the operator activates the steering controls, the control valves direct pressurized hydraulic fluid to the steering cylinders. The hydraulic fluid applies force to the cylinders, activating the steering mechanism. This allows the scissor lift to turn or change direction.

4. Return Stroke: Once the desired steering movement is achieved, the operator releases the steering control, and the control valves redirect the hydraulic fluid. This returns the steering cylinders to their original position, allowing the scissor lift to maintain a straight path.

5. Control Mechanism: The operator controls the steering through the steering controls located in the scissor lift's operator platform or control panel. The control valves regulate the flow and direction of hydraulic fluid to the steering cylinders based on the operator's input.

How the steering cylinder operates in a scissor fork type aerial work vehicle:

1. Hydraulic System: The scissor lift's hydraulic system consists of a pump, reservoir, control valves, and hydraulic cylinders. The hydraulic pump pressurizes hydraulic fluid (typically oil) and stores it in the pool. The control valves regulate the flow and direction of the hydraulic fluid.

2. Cylinder Configuration: The steering cylinder, or cylinders, are typically mounted within the steering mechanism of the scissor lift. The number and arrangement of steering cylinders can vary depending on the specific design of the vehicle.

3. Steering Operation: When the operator activates the steering controls, the control valves direct pressurized hydraulic fluid to one side of the steering cylinder. This pressurized fluid exerts force on the piston inside the cylinder, causing it to extend. The extension of the piston, in turn, applies pressure to the steering mechanism, enabling the scissor lift to turn or change direction.

4. Return Stroke: Once the desired steering movement is achieved, the operator releases the steering control, and the control valves redirect the hydraulic fluid to the opposite side of the steering cylinder. The pressurized fluid now acts on the other side of the piston, causing it to retract. This piston retraction returns the steering mechanism to its original position, allowing the scissor lift to maintain a straight path.

5. Control Mechanism: The operator controls the steering through the steering controls on the scissor lift's operator platform or control panel. The operator's input is translated into appropriate commands that regulate the flow and direction of hydraulic fluid to the steering cylinder via the control valves.

Testing

To further improve product performance, and establish the leadership position of our hydraulic cylinder in the industry, our company and zjimee jointly established a Comprehensive performance laboratory of hydraulic cylinders, hydraulic valves, and hydraulic pumps; the lab is computer-assisted testing, using electro-hydraulic control technology, the test conditions preset by computer, which improves the test accuracy and system versatility, and the experimental data.
The automatic collection is realized through the application of sensors, and the output data, such as the internal leakage and load efficiency of the cylinder or the valve, are directly processed by the computer and converted to standard units (ml/min; %). At the same time, to ensure the working safety of the hydraulic system, the state monitoring function is carried out for key performance parameters, such as "oil temperature monitoring, liquid level monitoring, filter device monitoring," etc. Among them, the hydraulic cylinder test stand can test the performance of "load efficiency" and "internal leakage" by readings. At the same time, it is equipped with a grating ruler measuring instrument, which meets the requirements of all test items of hydraulic cylinder products in the national standard.
