Product Description

The HCIC 6TG-E130x1947 underbody telescopic hydraulic cylinder for dump trailers has 6 stages, 1,947 mm stroke, 180 bar pressure and up to 11-18 ton tipping capacity.

Product Detail

The 6TG-E130x1947 is a six-stage underbody telescopic hydraulic cylinder for dump trailers. It has a 1,947 mm stroke, a listed working volume of 14 L, a maximum working pressure of 180 bar and a tipping capacity range of 11-18 tons. Its catalog dimensions include A 543 mm, B 216 mm, C 327 mm, D 132 mm and E 92 mm, with a listed mass of 53 kg.

The cylinder belongs to HCIC's underbody range for light-duty dump equipment, including side-dump and three-way dump trailer applications. The final installation must still be checked against the trailer frame, hinge geometry, load path, oil circuit and available mounting space.

I. What the 6TG-E130x1947 Is Designed to Do

An underbody telescopic cylinder uses several nested stages to create a long working stroke while keeping the retracted package shorter than a single long cylinder. That layout is useful where the cylinder must fit beneath a dump body and still provide enough movement for tipping.

The 6TG-E130x1947 underbody telescopic hydraulic cylinder uses six stages. As hydraulic oil enters the cylinder, the stages extend in sequence to produce the lifting movement. During retraction, the stages return into the nested assembly. The actual sequence and load behavior depend on the cylinder design, oil supply, mounting geometry and trailer structure.

This is not a universal replacement based only on stroke length. The closed installation dimensions, pin or eye arrangement, tipping angle, body weight and chassis mounting points must be checked before substitution.

The catalog also lists the underbody range with ball and eye versions, mounting brackets and supports, and several port options. The exact connection and mounting configuration for a quotation should be confirmed against the required drawing and trailer layout.

III. Understanding the Main Dimensions

The catalog identifies dimensions A through E on the product data. These dimensions are installation references, not interchangeable values. A replacement cylinder must match the actual pin-center, bracket, clearance and body geometry of the trailer.

A practical review should compare:

- The available space under the dump body when retracted

- The cylinder's working position and extension path

- Pin or eye alignment at both ends

- Clearance from the chassis, body, axles, hoses and other components

- The required tipping angle and the point where the cylinder reaches full extension

- The body hinge position and the direction of load transfer

The 1,947 mm stroke is only one part of the fit. A cylinder with the same stroke can still be unsuitable if its closed length, mounting height or connection geometry is different.

IV. Six-Stage Telescopic Construction

The six-stage construction allows the 6TG-E130x1947 to provide a long stroke from a compact underbody arrangement. The nested barrel sections share the extension task, so each stage and its sealing interface must work in the correct order.

Telescopic cylinders also require careful attention to alignment. The mounting brackets should guide the cylinder through its intended path without forcing the stages to carry side loads created by a distorted frame. The cylinder is a force-producing component; it should not be used to correct a hinge or chassis alignment problem.

The catalog describes the underbody range as available with brackets and supports. For an OEM installation, the bracket design, pin alignment and cradle arrangement should be reviewed together with the cylinder rather than treated as separate afterthoughts.

V. Pressure, Capacity and Application Limits

The catalog lists a maximum working pressure of 180 bar and a tipping capacity range of 11-18 tons for the 6TG-E130x1947. These figures must be read within the intended equipment configuration. They do not establish the payload rating of an entire trailer.

Actual tipping performance depends on body weight, payload distribution, hinge friction, cylinder angle, mounting position, hydraulic flow, pressure losses and structural strength. The trailer manufacturer remains responsible for checking the complete load path and safe operating conditions.

The 180 bar figure should also be matched with the pump, valve, hoses, fittings and mounting hardware. A system should not be operated above the permitted rating of its lowest-rated component.

VI. Sealing and Surface Information from the Catalog

HCIC's underbody cylinder description states that the seals used in this range are intended to resist permanent deformation and wear and to operate within a temperature range of -40°C to +100°C. The catalog also states that the stages use hard chroming and that the range is designed for a maximum working pressure of 200 bar in the general underbody feature description.

For the specific 6TG-E130x1947 table row, the listed maximum working pressure is 180 bar. The model-specific table value should be used for this product article and quotation. The broader range statement should not be used to replace the model's listed value.

The catalog presents the 6TG-E130x1947 as an underbody product for dump equipment. It does not provide a complete seal compound, surface-thickness, cycle-life or detailed maintenance interval for this specific model. Those details should be confirmed when the operating medium, climate and duty cycle are known.

VII. Installation Checks Before Ordering

A buyer replacing or specifying the 6TG-E130x1947 should prepare the following information:

1. Current cylinder model and identification plate, if available

2. Pin-center or eye-center dimensions in the retracted and extended positions

3. Required stroke and tipping angle

4. Dump body length, empty weight and intended payload range

5. Hinge location and mounting bracket drawing

6. Pump flow, system pressure and valve type

7. Hose connection and port requirements

8. Available space below the body and around the chassis

9. Operating temperature and expected exposure to water, dust or road contamination

10. Whether brackets, supports, cradle or a complete installation kit are required

Clear installation information reduces the risk of receiving a cylinder that has the correct stroke but cannot be safely fitted to the trailer.

VIII. Applications

The catalog associates the underbody telescopic range with light-duty dump equipment, side-dump and three-way dump trailer applications. The 6TG-E130x1947 may be considered where the equipment requires a long stroke and the six-stage design fits the available underbody space.

Application approval should be based on the complete mechanical and hydraulic review. A product description alone cannot confirm suitability for a specific trailer model, payload or tipping angle.

IX. FAQ

How many stages does the 6TG‑E130x1947 have?

The HCIC‑2026 catalog lists the 6TG‑E130x1947 as a six‑stage cylinder.

What is the listed stroke?

The catalog lists a 1,947 mm stroke.

What pressure is listed for this model?

The model table lists a maximum working pressure of 180 bar.

What tipping capacity range is shown?

The catalog lists an 11‑18 ton tipping capacity range.

Can it replace any cylinder with a 1,947 mm stroke?

No. The mounting dimensions, hinge geometry, bracket alignment, pressure, flow and complete load path must be checked before replacement.

Are brackets and supports available?

The general underbody product description states that brackets and supports are available in the range. The exact requirement for the 6TG‑E130x1947 should be confirmed in the quotation.

X. Request a 6TG-E130x1947 Fitment Review

The 6TG-E130x1947 underbody telescopic hydraulic cylinder combines a six-stage construction with a 1,947 mm stroke and catalog-listed dimensions for trailer integration. To request a technically useful quotation, send HCIC the existing cylinder details, mounting drawing, tipping angle, pump data and operating conditions.

HCIC can then check the model against the actual underbody installation instead of relying on stroke length alone.
