Underbody Telescopic Cylinders for Tipping Trailers (L130, L105, L90, L75)
An underbody tipping cylinder lies horizontally beneath a trailer chassis and lifts the body through a lever or link arrangement, staying protected from load and weather — the standard tipping layout on agricultural trailers. HCIC's L-series covers four first-stage bores — 130, 105, 90 and 75 mm — in 3 to 6 stages, with strokes from 676 mm to 1947 mm, working pressures of 18–22 MPa, and seals rated for -40 °C to +110 °C.
How to select an underbody cylinder
Step 1 — pick the stroke.
Measure the pivot distance L from the body hinge to the cylinder's front trunnion and decide the maximum tilt angle the body must reach, then read the required stroke from the selection chart in the underbody catalog. As a rule of thumb, a given pivot distance supports more tilt with more stages — the 105 mm bore is offered in 3, 4, 5 and 6 stages at overlapping strokes, so stage count is chosen to match the tilt requirement, not the stroke alone. Match the chart reading against the closed length (B) listed for each model to confirm the cylinder fits the chassis.
Step 2 — check the tipping capacity.
Match your fully loaded body weight against the tipping capacity column: L130 covers 11–25 t, L105 covers 5–18 t, L90 covers 4–14 t and L75 covers 4–9 t, depending on stage count and geometry.
Step 3 — match your system pressure.
L130 is rated 18 MPa, L105 is 20 MPa, and L90/L75 are 22 MPa — pick the series that matches your tractor or truck's hydraulic system.
How the part numbers group:
the first digit is the stage count (4TG- means four stages), E130/E105/E90/E75 is the first-stage barrel diameter in mm, and the number after x is the stroke in mm — for example 5TG-E130x1000 is a five-stage, 130 mm cylinder with 1000 mm of stroke. Send your pivot distance and target tilt angle with the inquiry, and HCIC's engineers will verify the selection before quoting.

Catalog notes
- Seal working temperature is -40 °C to +110 °C. Ports are available in G1/2, G3/8, M22, M18 and NPT1/2. Model 4TG-E105x984 exists in two bracket variants (different B/D/E dimensions); both are listed as separate rows. ↩
Frequently asked questions
How do I choose the right underbody tipping cylinder for my trailer?
Work through three checks: the stroke from your pivot distance L and target tilt angle (per the catalog selection chart), the tipping capacity against your fully loaded body weight, and the series rating against your system pressure — L130 is 18 MPa, L105 is 20 MPa, L90/L75 are 22 MPa. Send the measurements with your inquiry and HCIC's engineers will confirm the selection.
What is the difference between the L130, L105, L90 and L75 series?
The numbers are the first-stage bore in millimetres: 130, 105, 90 and 75. Larger bores tip heavier bodies — the L130 covers 11–25 t depending on stage count and geometry, while the L75 covers 4–9 t.
How many stages do underbody cylinders have?
Between 3 and 6. Stage count rises with the stroke required from a given closed length: a 105 mm bore is built in 3, 4, 5 and 6 stages across the range, with stage diameters stepping down in 15 mm increments (e.g. 105/90/75/60/45/30 mm on the 6-stage).
