Port front crane telescopic hydraulic cylinder product introduction: The excavator hydraulic cylinder processed and manufactured by our company, the cylinder head and cylinder cover are made of rolled steel and cast iron, and can also be processed with materials specified by the customer. The cylinder barrel is made of seamless steel pipe grinding. It can make the inner hole achieve a high smoothness, reduce internal friction and extend the service life of the seal. Each batch of purchased materials has a material inspection report, and its materials and material properties are strictly in accordance with customer requirements.

Port Front Crane Telescopic Hydraulic Cylinder product overview:

The telescopic hydraulic cylinder has two or multi-stage activators. The order of the activators in the telescopic hydraulic cylinder is from large to small, while the order of no-load retraction is generally from small to large. The telescopic cylinder can achieve a longer stroke, but has a shorter length when retracted, making the structure more compact. This kind of hydraulic cylinder is often used in construction machinery and port reach stacker machinery. There are multiple pistons that move at once. When each piston moves successively, its output speed and output force change.

Product advantages of port front crane telescopic hydraulic cylinder:

1. The advanced electroplating process and surface strengthening design allow the cylinder to have excellent corrosion resistance and meet the needs of port machinery in seaside working conditions;

2. The unique rod support design enables the cylinder to have excellent tensile rod performance under extreme working conditions.

3. The unique ultra-low speed structural design allows the luffing and telescopic cylinders to have excellent low-speed dynamic performance, improving

The micro-movement performance of the host enables more precise operation;

4. A highly electro-hydraulic integrated latch mechanism enables the design of single-cylinder latch structures for medium and large tonnage cranes;

5. New high-strength piston rod materials are used to meet the increasing needs of the main engine’s lifting performance.

6. When the pressure oil enters from the rodless chamber, the cylinder tube with the largest effective area of the piston begins to extend. When it reaches the end point, the cylinder tube with the second largest effective area of the piston begins to extend. The order of telescopic hydraulic extension is from large to small, which can achieve a long working stroke. The smaller the effective area of the extended cylinder, the faster the extension speed. Therefore, the extension speed changes from slow to fast, and the corresponding hydraulic thrust changes from large to small; this change pattern of thrust and speed is suitable for the thrust and speed requirements of various automatic loading and unloading machines. The order of retraction is generally from small to large. The axial length during retraction is shorter, takes up less space, and has a compact structure.

Safety buffer function of the port front crane telescopic hydraulic cylinder: According to needs, various valves with special slow return, counting balance and emergency closing functions can be easily installed. It also has a built-in buffer mechanism that absorbs shock at the end of the stroke. To ensure safer use of the cylinder.
