OEM Single Acting Multi-Stage Hydraulic Cylinder for Dump Truck

Single-acting multi-stage telescopic structure, long effective lifting stroke, small retracted overall length, perfect for limited installation space of dump truck chassis.

Adopt 27SiMn high-strength alloy seamless steel pipe for cylinder barrel, thick pipe wall, strong pressure resistance and anti-deformation ability, adapt to frequent heavy-load tipping operation.

Multi-section piston rod with overall quenching + thick hard chrome plating, wear-resistant, anti-rust and anti-scratch, durable under complex road bumping and muddy working conditions.

Imported multi-layer combined oil seal and dust-proof ring, patented anti-leakage structure, effectively prevent hydraulic oil leakage caused by long-time high-frequency reciprocating work.

Built-in end hydraulic buffer device for each stage cylinder, slow down the impact of final stretching limit, protect cylinder body and dump truck carriage frame from collision damage.

Full penetration submerged arc welding for cylinder bottom and connecting earring, excellent anti-fatigue performance, resist continuous vibration during vehicle driving and unloading.

Precision internal honing processing for each stage inner hole, low internal friction, smooth stretching and retracting without jamming or shaking.

Full OEM customization: stages quantity, total stroke, mounting hinge hole size, oil port thread specification and working pressure can be customized according to different dump truck models.

Compact layered telescopic layout, lightweight and high load capacity, widely compatible with light, medium and heavy-duty dump trucks, tipper trailers and sanitation garbage trucks.
