3×16 Hydraulic Cylinder – 16″ Stroke
AMRAP Hydraulics presents a welded cross-tube cylinder with a 3″ bore and a 16″ stroke. It operates at up to 3500 PSI with a 21200 lb load capacity and SAE #8 ports. The all-welded steel construction and corrosion-resistant seals are designed for harsh outdoor conditions, providing a rugged option for dump systems requiring substantial reach and strength in a compact form factor.
3×12 Hydraulic Cylinder – 12″ Stroke
This AMRAP Hydraulics model features a 3″ bore, 12″ stroke, and 21,200 lb load capacity with welded double-acting design and SAE 8 ports. Its all-welded construction emphasizes durability and reliability in outdoor work, supporting stable lifting performance across a wide range of dump body sizes and operations.
WEN TR3024 2500 PSI Cylinder – 24″ Stroke
The WEN TR3024 provides a 24″ stroke at 2500 PSI with a 3″ bore and a 1.25″ rod diameter. It uses a tie-rod design and a standard 1/2″ NPT port, offering reliable performance for moderate-duty dump applications. The ASAE-compatible construction ensures compatibility with common hydraulic systems in many light to medium-duty dump setups.
CWA Hydraulics TR Tie Rod Cylinder – 3″ Bore x 12″ Stroke
This CWA Hydraulics model offers a 3″ bore, 12″ stroke, and a 2500 PSI rating with SAE 8 and 1/2 NPT ports. It emphasizes a robust tie-rod design and a compact footprint, making it suitable for applications requiring precise stroke control and reliable performance in constrained mounting spaces.
CWA Hydraulics TR Tie Rod Cylinder – 3″ Bore x 14″ Stroke
This model features a 14″ stroke with 3″ bore and 2500 PSI capacity, offering extended reach compared to shorter stroke variants. The retracted length and mounting details are important for ensuring compatibility with existing dump bed assemblies, particularly in tight spaces where mounting flexibility matters.
Buying Guide
Key purchase considerations for 3-stage telescopic cylinders include stroke length versus overall height when retracted, load capacity, and compatibility with existing hydraulic systems and mounting configurations. For dump trucks, prioritize cylinders with:
- High load capacity to handle expected payloads without compromise
- Long stroke to accommodate large dump bodies and tilting angles
- Robust mounting hardware and welded or cross-tube designs for durability
- Port type compatibility (SAE 8, NPT, or metric) with current hoses and fittings
- Resistance to corrosion and external elements, especially for off-road use
- Ease of installation and availability of replacement seals or parts
Performance considerations vary by application. For engineering-focused fleets, a higher PSI rating and a welded cross-tube build offer longevity in challenging environments. For retrofit projects, ensure the chosen model aligns with existing frame dimensions and mounting points to minimize fabrication work. When comparing options, evaluate total extended reach against collapsed height to ensure full operational range without striking the chassis or other components.
