3-Stage Telescopic Hydraulic Cylinders for Dump Trucks & Trailers
Heavy-Duty Multi-Stage Tipping Cylinders | Single-Acting Gravity Drop & Custom Double-Acting Systems
DALLAST designs and manufactures multi-stage telescopic hydraulic cylinders engineered specifically for commercial dump bodies, tipper trailers, and agricultural tipping chassis. Featuring a compact retracted mounting length and an extended multi-stage stroke, our 3-stage cylinders deliver reliable lifting force under severe off-highway and construction working conditions.
Constructed from high-tensile 27SiMn alloy steel with hard chrome-plated stage sleeves, each cylinder is precision-machined to ensure superior bending resistance, low internal friction, and zero external leakage across operating pressures of 16 to 22 MPa (up to 220 bar).

Product Process
How to Select the Right 3-Stage Hydraulic Cylinder
The cyinder selection should be based on the dump body geometry, lifting load, installation space, required stroke and hydraulic system pressure, and must be verified by qualified engineers.
Selection Factor
Dump Body Length & Required Stroke
Consider the dump body length, lifting geometry, and target tipping angle to determine the required cylinder stroke.
Lifting Load
Ensure the cylinder's closed length and outer diameter fit the available truck frame and mounting space.
Installation Space
Ensure the cylinder's closed length and outer diameter fit the available truck frame and mounting space.
Working Pressure
Verify that the hydraulic system pressure and cylinder ratings meet the lifting force requirements at each stage.
Mounting Configuration
Check mounting types, pin dimensions, and connection points to ensure proper installation and compatibility.
Sizing & Engineering Selection Guide
Dump Body Length & Tipping Geometry
Provide body pivot position, rear overhang, and required tipping angle (typically 45° to 55°). These parameters define cylinder stroke, mechanical leverage, and trunnion mount locations.
01
Maximum Payload & Lift Capacity
Total tipping force must account for maximum gross load, body tare weight, adhesive materials (e.g., wet clay or asphalt), and safety factors during initial stage breakout.
02
Closed Center Distance & Installation Clearance
Confirm retracted pin-to-pin dimensions, head clearance behind the cab (front-end mount), or underbody space (underbody mount) throughout the full tipping arc.
03
Hydraulic System Compatibility
Verify pump flow rate (L/min) to determine cycle extension time, reservoir oil capacity to handle stage volume displacement, and relief valve settings.
04
Pivot Alignment & Mounting Configurations
Inspect top eye / ball bushing and bottom trunnion pin dimensions to prevent side-load forces and bending moments during uneven tipping surfaces.
05
Consult a Hydraulic Application Engineer
