Product Description

HCIC Underbody Telescopic Cylinders are engineered specifically for dump trailers, tipping vehicles, and light trucks. Designed for maximum lifting force in compact mounting spaces, these multi-stage cylinders (2 to 6 stages) deliver smooth operation, exceptional durability, and high corrosion resistance.

Designed as a direct drop-in replacement for major US cylinder brands, each unit features standard SAE (ORB) / NPT fluid ports and heavy-duty mounting trunnions. Whether you need a single replacement cylinder for a 12ft dump trailer or high-volume OEM supply, we provide ISO 9001:2015 certified hydraulic solutions paired with 12V/24V DC electric hydraulic power units—backed by factory-direct wholesale pricing, fast air/sea delivery (DDP available), and a comprehensive 1-year warranty.

Typical Applications

Underbody telescopic cylinders are widely used in:
Small dump trailers
Utility dump trailers
Agricultural and farm trailers
Tandem-axle dump trailers
Light construction and landscaping trailers

Quality Control Before Shipment

Every cylinder should be checked before it leaves the factory.

Our production and inspection process can include:
Raw Material Inspection → CNC Machining → Tube Processing → Stage Machining → Surface Treatment → Seal Installation → Cylinder Assembly → Hydraulic Pressure Test → Leakage Check → Extension & Retraction Test → Final Inspection → Export Packing

For OEM orders, inspection requirements can also be discussed before production.
The objective is not simply to manufacture the cylinder, but to make sure the delivered product matches the confirmed technical specification.

OEM & Custom Underbody Hydraulic Cylinders

Not every dump trailer uses a standard cylinder.
For OEM manufacturers, trailer manufacturers, hydraulic distributors, and replacement-parts suppliers, we provide custom telescopic hydraulic cylinder manufacturing based on customer requirements.

You can provide:
* Technical drawing
* Existing cylinder sample
* OEM part number
* Cylinder dimensions
* Trailer model
* Required stroke
* Stage number
* Mounting dimensions
* Hydraulic pressure
* Application photos

Our engineers can use this information to confirm the cylinder configuration before production.
This approach helps reduce compatibility problems and unnecessary modifications during installation.

The production lead time depends on cylinder specifications, quantity, customization requirements, and the current production schedule; it generally ranges from 30 to 50 days.

Quality Assurance & After-Sales Support

We understand that hydraulic cylinders are working components, not simply replacement parts.
Our products come with a one-year warranty.
If a customer experiences a technical issue after delivery, our team can review the cylinder specification, installation conditions, operating pressure, photos, videos, and other relevant information to help identify the cause.

For OEM and customized orders, technical documentation and inspection requirements can be confirmed before production.
Our goal is to provide support throughout the process:
Specification → Engineering Confirmation → Production → Inspection → Shipment → After-Sales Support
