25MPa Hydraulic Lifting Cylinder for Scissor Fork Type Aerial Work Vehicle Hydraulic Cylinders

In a scissor fork-type aerial work vehicle, the lifting cylinder is a hydraulic component responsible for raising and lowering the scissor arms, extending or retracting the platform. The lifting cylinder is vital in providing vertical movement and height adjustment capabilities to the scissor lift. 

Here's an overview of how the lifting 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: Scissor fork-type aerial work vehicles typically have multiple lifting cylinders positioned between the scissor arms. The number and arrangement of lifting cylinders depend on the specific design and lifting capacity of the vehicle.

3. Lifting Operation: When the operator activates the lifting controls, the control valves direct pressurized hydraulic fluid to the lifting cylinders. The hydraulic fluid enters the cylinders and applies force to the pistons inside. As the pistons extend, they push against the scissor arms, causing them to unfold and raise the platform to the desired height.

4. Lowering Operation: The operator releases the lifting controls to reduce the platform, and the control valves redirect the hydraulic fluid. This allows the hydraulic fluid to flow out of the lifting cylinders, causing the pistons to retract. The retraction of the pistons compresses the scissor arms, gradually lowering the platform to the desired position.

5. Control Mechanism: The operator controls the lifting operation through the lifting 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 lifting cylinders via the control valves.

Application of Scissor fork type Aerial work vehicle Lifting cylinder

1. Construction and Maintenance Work: Scissor fork-type aerial work vehicles are commonly used in construction and maintenance tasks where workers need to access elevated areas. The lifting cylinder allows the platform to be raised to the desired height, providing a stable and secure working platform for painting, repairs, installation, and maintenance work on buildings, equipment, or infrastructure.

2. Warehousing and Inventory Management: Scissor lifts with lifting cylinders are used in warehouses and storage facilities to access high shelves and racks. The lifting mechanism allows workers to reach inventory stored at elevated levels safely. This is particularly useful for picking, stocking, and organizing goods in warehouses or distribution centers.

3. Electric and Telecommunication Infrastructure: Aerial work vehicles equipped with lifting cylinders are employed to install, maintain, and repair electrical and telecommunication infrastructure. Workers can elevate the platform to reach overhead cables, power lines, or communication equipment, enabling efficient inspections, repairs, or installations.

4. Event and Venue Setup: Scissor lifts with lifting cylinders are used in event management and venue setup. They provide a safe and stable platform for setting up lighting, sound systems, decorations, and signage in large event spaces, stadiums, concert halls, and exhibition centers.

5. Tree Care and Landscaping: Lifting cylinders in scissor fork-type aerial work vehicles are utilized in tree care and landscaping tasks. Arborists and landscapers can access tree canopies or elevated areas to prune branches, trim trees, or perform landscaping activities with ease and safety.

6. Industrial Maintenance: In industrial settings, scissor lifts with lifting cylinders are employed for maintenance and inspection tasks. They allow workers to access elevated equipment, machinery, or structures for routine inspections, repairs, or installation of components.

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.
