Telescopic 5 Stage Hydraulic RAM Rollover Cylinder for Side Dumper Truck

Cylinder Advantages:

• We are professional manufacturer in hydraulic. We will provide competitive price.
• OEM service is available.We are pleased to process according to the customer's drawings.
• We have professional R&D team with rich design experience.
• We also establish strict but scientific product testing system so that products have perfect performance.

     Rollover cylinder is a single-acting multi-stage hydraulic cylinder, the main role in the trailer, semi-trailer modification, dump truck rollover compartment lift cylinder. Reasonable design, compact structure. Production of a spherical hinge shaft, earrings hinge shaft and other connections, a variety of processes to choose from.

     Single-acting multi-stage telescopic sleeve hydraulic cylinder, with small size, large stroke and other advantages, can be used for heavy vehicles, agricultural vehicles and other vehicles tilting the bucket lift cylinder.

     Multi-stage hydraulic cylinder for large stroke and installation distance or total length (stroke can be greater than the installation distance or total length) occasions.

     The series of hydraulic cylinder working pressure, working stroke, installation distance, the use of series, all levels of stroke and piston rod diameter and other parameters can be designed according to customer needs.

     Certainly, you can provide drawing and product photos so that we can understand your meaning more conveniently, or you can also send us sample and we produce for you according to your sample.

Quality control:

1. External Inspection: Purchased Item Inspection, Outsourcing Item Inspection
2. Process Inspection: First Inspection, Random Inspection, Handover Inspection
3. Final Quality Inspection: External Dimensions Inspection, 100% Hydraulic Test
4. Type Inspection
Every piece of hydraulic cylinder are tested and will send out only after they are pasted the each test.

     We firmly believe that quality products from the outstanding design and concept,engineers with rich experience in our strong technical team. Analyzes, calculations, strength check and motion simulation in variety of software to make our design more close to actual working conditions, We will consider various factors in the design stage to avoid each risk of project failure. Our design and products could perfectly match customers' varied needs.

Product Process:

1. Raw materials entering the factory, 27SiMn, 40CrMo, ST52, 45# steel tubes or bars for choice
2. Do the pre-treatment including pickling, phosphating and saponification, and then cold-draw the seamless steel tubes.
3. Put the steel tubes into the tempering furnace to do the stress relief annealing in convenience of the subsequent the processing.
4. Multi-roll straightening machine, with 10 straightening points, achieves the automatic rolling straight improving the efficiency greatly
5. Heat treatment to obtain work pieces with different properties by changing their internal microstructure or surface chemical composition.
6. Cylindrical degree can be controlled within 0.03mm and the surface roughness is up to 0.4 by honing with range:φ40mm-φ450mm and longest length: 12000mm
7. Machining processes to obtain high precision parts with complex shapes strictly according to the detailed drawings.
8. Electroplating production process fulfills the functional and ornamental requirements for coating work pieces of different dimensions according to specific application requirements.
9. Cleaning all the parts by automatic cleaning machine in the special solution and under special temperature control effectively.
10. All the parts are assembled into complete cylinders according to the strict assembly instructions by skillful workers in dust-free workshop.
11. Do proof pressure and performance tests to check whether the cylinders can operate smoothly and stably under the specified pressure with no leakage and deformation.
12. Do the painting including high quality primer and topcoat to obtain beautiful appearance and protect the cylinders against the anticorrosion.
13. Wooden pallet or boxes packing with plastic films wrapped on the surface, suitable for long-time sea transport.
