A technical teardown of the 5TG-E130x1155 5-Stage 1155mm Stroke Underbody Telescopic Tipping Cylinder for Commercial Tipper Trucks, examining its 5-stage expansion architecture, 1,155 mm stroke, 449 mm collapsed length, 13-to-22 metric ton tipping capacity, 180 bar max pressure, and versatile trunnion cradle mounting for medium commercial tippers and three-way dump bodies.

5 Precision Ground Hard-Chromed Expansion StagesTotal Power Stroke Travel:
1,155 mm (45.47 inches continuous elevation)Collapsed Closed Body Length (L):
449 mm (17.68 inches low-profile chassis height)Base Outer Shell Diameter (C):
132 mm (compact underbody trunnion envelope)Upper Stage Diameter Steps (D / E):
92 mm / 58 mm precision hard-chromed steel sleevesTrunnion Pivot Dimensions (A / B):
A = 216 mm / B = 233 mm mounting bracket footprintOn medium-duty commercial tipper trucks, construction utility bodies, and three-way side-dump trailers, body builders face extremely tight clearance between chassis frame rails and the truck bed floor. Mounting a bulky direct-push cylinder forces the truck bed higher, dangerously raising the vehicle’s center of gravity.
Furthermore, poorly engineered multi-stage cylinders suffer severe hydraulic pressure spikes and jarring shudder when stepping between telescoping sleeve stages.
The 5TG-E130x1155 5-Stage 1155mm Stroke Underbody Telescopic Tipping Cylinder for Commercial Tipper Trucks solves both spatial and dynamic challenges. Featuring five precision-machined nested stages housed within a 130 mm base envelope, this compact underbody hoist delivers 1,155 mm (45.5 inches) of powerful elevation from an ultra-low 449 mm (17.7 inches) collapsed closed length, producing 13 to 22 metric tons of tipping force at 180 bar operating pressure.

When a telescopic cylinder extends under load, fluid pressure must automatically increase as the cylinder transitions from a large-diameter sleeve to a smaller-diameter sleeve. The 5TG-E130x1155 5-Stage 1155mm Stroke Underbody Telescopic Tipping Cylinder for Commercial Tipper Trucks features precision-engineered volume displacement ratios between all five stages (132 mm base down to 58 mm final stage). Combined with internal metering dampening channels, this eliminates sudden pressure surges and provides smooth, linear bed acceleration from horizontal rest to full 50-degree dump angle.
Standard fixed-pin cylinders can only pivot in a single longitudinal plane. The 5TG-E130x1155 is available with interchangeable ball-and-socket rod eye mounts and oscillating chassis support cradles. This allows the cylinder to gimbal freely in both longitudinal and lateral planes, enabling reliable operation on European-style three-way tippers that dump to the rear, driver-side, or passenger-side without twisting the cylinder barrel.
| Stage | Material & Specification |
|---|---|
| Stage 1 (132mm Outer Shell) | Cold-Drawn Seamless St52-3 Alloy Steel |
| Stages 2, 3, 4 (Mid Sleeves) | Precision Honed & Hard Chrome Plated (25μm Layer) |
| Stage 5 (58mm Top Sleeve) | Ball/Eye Rod End + Permanent Deformation Seal Pack |
1. St52-3 High-Tensile Seamless Tubes: Micro-alloyed cylinder tubes offer superior yield strength and cold impact resistance down to -40°C.
2. Dense Hard Chrome Electroplating: Each moving sleeve is plated with a minimum 25um hard chrome layer, providing mirror surface finish and complete corrosion resistance against road washdown.
3. Anti-Extrusion Polyurethane Seals: Specially formulated seal compounds resist permanent set and seal extrusion across an extreme thermal window from -40°C Arctic winters to +100°C continuous hydraulic oil temperatures.
4. Heavy Dirt Scraper Wipers: Prevent concrete slurry, stone dust, and gravel grit from penetrating internal sleeve bearings during dirty job site dumping.
To ensure optimal tipping leverage and structural longevity on commercial tippers:
Mounting Position Optimization: Locate the underbody trunnion pivot cradle approximately 35% to 40% forward from the rear body hinge line. This ensures low initial breakout hydraulic pressure while providing adequate stroke to achieve full material discharge.
Confirm Hydraulic Reservoir Sizing: Ensure the truck PTO hydraulic tank has at least 15 to 18 liters total volume to support the 9.3-liter displacement of the cylinder with sufficient thermal cooling buffer.
Port Fitting Flexibility: Select between standard G1/2 BSPP, M22x1.5 metric, or NPT1/2 port adapters depending on your vehicle's hydraulic valve block configuration.
