Underbody Tipping Cylinder for 8-Ton Tipper Trucks

In the 3.5-ton to 7.5-ton commercial vehicle segment (such as Ford Transit, Iveco Daily, Isuzu NPR, and Mercedes-Benz Sprinter chassis cabs), strict gross vehicle weight (GVW) limits make every kilogram of tare weight critical. Traditional low-pressure (140 to 160 bar) telescopic hoists require large-diameter, thick-walled steel tubes that add 50 to 70 kg of deadweight and require bulky 25-liter oil reservoirs.

The 5TG-E90x1256 5-Stage 1256mm Stroke 220-Bar Underbody Tipping Cylinder for 8-Ton Tipper Trucks revolutionizes light tipper engineering by operating at 220 bar (22.0 MPa / 3,190 psi):

1. Radical Weight Reduction: By utilizing high-pressure force density and high-tensile alloy steel tubing, the entire 5-stage cylinder weighs just 25 kg (55 lbs), increasing the vehicle's legal payload capacity.
2. Minimal Oil Demand: The compact nested multi-stage configuration requires a working displacement of only 4.7 liters, allowing body builders to install a compact 8-to-10-liter hydraulic tank and saving valuable chassis frame space for toolboxes or battery packs.
3. Ultra-Low Collapsed Profile: With a collapsed closed height of just 449 mm (17.68 inches), the hoist mounts cleanly underneath low-deck flatbeds without requiring floor cutouts or raised subframes.

I. High-Pressure 220-Bar Technical Matrix & Dimensions

The 5TG-E90x1256 5-Stage 1256mm Stroke 220-Bar Underbody Tipping Cylinder for 8-Ton Tipper Trucks is manufactured with micrometer-precision tolerances to ensure smooth multi-stage sequencing under high pressures:

II. Multi-Port Versatility & Trunnion Cradle Alignment

The 5TG-E90x1256 5-Stage 1256mm Stroke 220-Bar Underbody Tipping Cylinder for 8-Ton Tipper Trucks is designed for universal chassis integration:

• Dual-Trunnion Cradle Mounting: The lower cylinder body mounts into an oscillating trunnion cradle equipped with greaseable bronze spherical bushings. This allows 3-way multi-directional tipping (rear dump, left side dump, or right side dump) without imposing damaging side loads on the extended telescopic sleeves.
• Top Pin Eye & Ball-Socket Options: Available with standard forged top pin eye bushings or spherical ball-and-socket sockets for quick hook-up to the tipper subframe.
• Universal Port Threading: The base inlet port can be factory-machined with G1/2, G3/8, M22x1.5, M18x1.5, or NPT1/2 threads, enabling direct connection to European, Asian, or North American hydraulic hose assemblies without bulky adapters.

III. Body Builder Hydraulic Sizing & Installation Best Practices

Follow these engineering recommendations when installing the 5TG-E90x1256 5-Stage 1256mm Stroke 220-Bar Underbody Tipping Cylinder for 8-Ton Tipper Trucks:

1. Subframe Cradle Squaring: Ensure the trunnion cradle mounting brackets are welded parallel within ±0.5 mm to prevent torsional binding during cylinder articulation.
2. Pressure Relief Calibration: Set the hydraulic power unit or PTO pump main relief valve to 220 bar (maximum). Never bypass or over-tighten the relief valve.
3. Bleeding & Cycling: After connecting fluid lines, elevate the empty body to full extension twice at low pump RPM to purge air from the 5 internal stages back into the reservoir.
4. Fluid Cleanliness: Use ISO VG 32 or ISO VG 46 anti-wear hydraulic oil filtered to ISO 4406 18/16/13. High-pressure 220-bar systems require clean fluid to prevent micro-scoring on the 30mm final stage chrome.
