What are the main uses of AL Series cylinders on tractors?

–Three-point hitch: Single-acting (50-80 mm bore) cylinders provide 15-50 kN lift for implements; gravity lowers them.
- Front loaders: Single-acting for lift, double-acting for bucket tilt; fit major OEM models (John Deere, Case IH, New Holland, Kubota).
- Draft control: Single-acting cylinders with spring return regulate implement depth by soil resistance.
- Steering assist: Single-acting cylinders reduce effort and ensure precise steering.

Hydraulic Cylinders in Heavy-duty Truck and Trailer Applications

• Agricultural Tipping Trailers: Single- and tandem-axle trailers for grain, silage, and manure use 2- to 3-stage telescopic cylinders (60–100 mm bore, 2000–4000 mm stroke).
• Construction Dump Trucks: Rigid and articulated trucks in quarry, mining, and earthmoving need 3- to 5-stage cylinders (125–200 mm bore, 4000–6000 mm stroke) rated for 200–250 bar continuous pressure.
• Waste Collection Vehicles: Roll-off and rear-loading trucks use single-acting cylinders for container lift and compaction.
• Livestock Transport: Trailer roof and side-panel lift cylinders require the corrosion resistance and reliable sealing of the TT Series.

What agricultural machinery are Parker PGP series hydraulic pumps suitable for?

• Tractor Hydraulic Systems: The PGP30 and PGP50 series power the hydraulic lift, steering, and auxiliary circuits on compact and medium tractors. Priority flow valve configurations (PGP31/PGP51) provide constant-flow steering circuits with excess flow directed to implement hydraulics.
• Harvesting Equipment: Combine harvesters and forage harvesters utilize PGP50 and PGP75 series pumps to power header drive, reel lift, grain tank elevation, and residue management systems.
• Sprayers and Spreaders: Self-propelled and trailed sprayers require reliable hydraulic power for boom lift, fold, and suspension systems. PGP30 and PGP50 series pumps provide the moderate flows required.

What are the key structural advantages of a hydraulic cylinder? 🔧

●Cylinder Barrel 🏗️: Cold-drawn seamless steel tube with honed inner bore, inner wall roughness Ra0.2~0.4μm, ensuring durable sealing; inner diameter 40~200mm, wall thickness designed according to pressure bearing and safety factors.

●Piston Rod ⚙️: Hard chrome-plated carbon steel / quenched alloy steel, chrome plating layer 20~30μm, wear-resistant and corrosion-resistant, suitable for harsh engineering and agricultural conditions; rod diameter 20~140mm, optional as needed.

●Piston Assembly 🔩: One-piece / split structure, equipped with wear-resistant rings and pressure-bearing seals, suitable for single-acting conditions; ductile iron, aluminum alloy, and steel are available to match different pressures and working intensities.

●Sealing Assembly🛡️: Three-layer multi-lip combined seal, with the main seal being PU/NBR, paired with an oil scraper ring and dustproof ring, providing leak-proof performance within a temperature range of -30℃ to 100℃, and stable hydraulic pressure sealing.

●Mounting Accessories📎: Universal mounting types including hinges, trunnions, flanges, and bases, directly replacing original cylinders from major brands.
