4.0" to 36.0"On light commercial 3.5-ton to 10-ton dump trucks and agricultural utility trailers, hydraulic space beneath the chassis frame is tightly constrained by exhaust mufflers, fuel tanks, and rear axle crossmembers.
Traditional tie-rod cylinders are bulky, prone to tie-rod stretching under high-pressure shock loads, and have square end caps that trap road mud and agricultural corrosive fertilizer.
The Standard HCL Welded Hydraulic Cylinder for Small Dump Truck with 20 Ton Capacity utilizes a heavy-duty round welded barrel design:
Compact Outer Envelope: With no bulky tie-rods or protruding exterior tie-rod nuts, the cylindrical welded body fits easily into narrow subframe stringers.
3,000 PSI Hydraulic Force Density: Operating at 3,000 PSI (207 bar), a 4.0" or 5.0" bore welded cylinder generates up to 58,900 lbs (26.7 metric tons) of raw breakout thrust, easily handling 20-ton payload dump angles on short-wheelbase tippers.
Fatigue-Resistant Welded Base: Automated robotic submerged-arc welds join the heavy forged base cross-tube directly to the seamless barrel, eliminating base-cap separation under heavy off-center loading.
| Comparison Item | Details |
|---|---|
| LIGHT CHASSIS RIGGING | TIE-ROD VS. HCL WELDED CYLINDER |
| Tie-Rod Cylinder | Bulky, Exterior Nuts, Stretches under Shock |
| HCIC HCL Welded Cylinder | Compact Round Profile, 3,000 PSI Rating |
| Cylinder Construction | Forged Base → Seamless Heavy-Wall Steel → Threaded Gland |
| Key Benefit | Fits Tight Chassis Channels / Handles 20-Ton Tipper Breakaway |
A major pain point for trailer fabricators is sourcing cylinders with non-standard pin holes that require custom machining or bushing spacers.
Every Standard HCL Welded Hydraulic Cylinder for Small Dump Truck with 20 Ton Capacity is manufactured with standardized precision cross-tube pin ends:
1. Standardized Pin Sizes: Precision reamed to 1.000", 1.250", and 1.500" tolerances to match standard North American and European trailer hinge pins without slop.
2. Integrated Grease Zerks: Every cross-tube end includes a recessed, protected Zerk fitting and internal spiral grease grooves, ensuring fresh grease purges abrasive road grit out of the pivot interface.
3. Double-Acting Hydraulic Down-Force: Unlike single-acting gravity cylinders that hang up on cold mornings, the double-acting circuit powers the dump box down in under 12 seconds, pulling sticky clay and wet mulch down firmly onto chassis rubber stops.
| Stage | Component | Function |
|---|---|---|
| 1 | Polyurethane Double-Lip Wiper Ring | Wipes mud, grit & ice |
| 2 | Hallite Style 605 High-Pressure U-Cup | Zero leakage @ 3,000 PSI |
| 3 | High-Tensile POM / Phenolic Wear Bands | Prevents metal galling under side loads |
| 4 | Ductile Iron Threaded Gland Collar | High-torque spanner serviceability |
Select the appropriate Standard HCL Welded Hydraulic Cylinder for Small Dump Truck with 20 Ton Capacity configuration based on your dump body length and tipping geometry:
| Model | Bore × Rod Diameter | Retracted Length | Full Stroke Length | Extended Total Reach | Pin Eye Diameter |

| HCL-3016 | 3.0" Bore × 1.50" Rod | 24.25" (616 mm) | 16.0" (406 mm) | 40.25" (1,022 mm) | 1.000" / 1.250" |
| HCL-4020 | 4.0" Bore × 2.00" Rod | 30.25" (768 mm) | 20.0" (508 mm) | 50.25" (1,276 mm) | 1.250" / 1.500" |
| HCL-5024 | 5.0" Bore × 2.50" Rod | 36.25" (921 mm) | 24.0" (610 mm) | 60.25" (1,530 mm) | 1.500" Pin |
| HCL-5036 | 5.0" Bore × 2.50" Rod | 48.25" (1,225 mm) | 36.0" (914 mm) | 84.25" (2,140 mm) | 1.500" Pin |
Rated working pressure is 3000 PSI, designed for heavy-duty tipper, agricultural and chassis rigging applications.
Yes. Threaded gland design allows easy seal replacement with standard high-torque spanner tools.
4-stage seal architecture: polyurethane double-lip wiper, Hallite 605 high-pressure U-cup, POM/phenolic wear bands and ductile iron gland collar.
Yes. The double-lip wiper ring wipes mud, grit, ice and debris to protect the internal sealing system.
Standard pin-eye mounting. Pin eye diameter options include 1.000", 1.250" and 1.500".
HCL welded cylinders feature compact round profile, smaller outer dimension for tight chassis channels. Tie-rod cylinders are bulkier and may stretch under heavy shock loads.
Custom lengths, bore and rod combinations are available upon request. Please send your working dimension requirements.
Seamless heavy-wall steel tube with forged base for high strength and impact resistance.
Standard models in stock ship quickly; custom non-standard specs require extra production lead time.
Standard listings are imperial inch sizes. Metric modified versions can be made for special orders.
Trailer builders and repair shops should follow these 4 installation steps:
1. Pin Alignment & Parallelism: Ensure chassis mounting brackets and dump body hinge tabs are aligned parallel within ±0.8 mm to prevent torsional side-binding on the chrome rod.
2. SAE O-Ring Port Connections: Install SAE #6 or SAE #8 O-ring boss adapter fittings, torquing to manufacturer specifications. Never use Teflon pipe tape on hydraulic ports.
3. Zero-Load Purge Cycle: Connect fluid lines to your 12V/24V DC power unit or tractor PTO valve. Cycle the cylinder to full extension and retraction three times at low flow to purge air bubbles back into the tank.
4. Grease Pin Journals: Pump EP-2 lithium grease into both cross-tube Zerk fittings until fresh grease purges around the bracket ears.
Whether you are mass-producing light commercial dump trailers or manufacturing agricultural tipping wagons, standardizing on the Standard HCL Welded Hydraulic Cylinder for Small Dump Truck with 20 Ton Capacity guarantees reliable lifting power at direct factory prices.
