Documentation Resources from Palfinger

Information in this article is sourced directly from Palfinger Liftgates ILT manuals and technical guides as well as our team’s expertise. Always refer to your specific liftgate’s manuals for complete procedures and serial number, model, and year-specific details.

Reference PDFs used:

• Interlift Palfinger ILT Installation Manual, Rev. 1.15 (2016)
• Interlift Palfinger ILT WR/PD Owner’s Manual, Rev. 1.4 (2013)

Why OEM Parts Matter for Safety and Performance

Using genuine OEM liftgate parts ensures precise fit, reliable hydraulic operation, and compliance with Palfinger’s tested design standards. The ILT liftgate’s structural strength, electrical control system, and rated load capacity depend on the correct materials and finishes (ILT Parts Manual, p. 3–4).

Advantages of OEM Palfinger components:

• Proper mechanical alignment and pressure ratings
• Factory-approved coatings such as galvanized, galvanealed, or powder coat finishes
• One-year parts warranty covering manufacturing defects (Parts Manual, p. 3)
• Compatibility with Palfinger’s hydraulic power units and electrical harnesses

Non-OEM parts can compromise lift performance, cause misalignment, or void warranty coverage.

How to Identify the Correct Parts

Locate the Serial Number Tag

Each ILT model’s serial tag is located on the curb-side (right side) of the mount tube, showing model, serial number, and production date (Parts Manual, p. 4).

When ordering, always include:

• Model number (e.g., ILT 35 or ILT 40)
• Serial number
• Finish type (black, galvanized, or powder-coated)

Include Complete Information When Ordering

Palfinger requires the model, serial number, part number, and description for every order (Parts Manual, p. 3). Providing complete data ensures the correct part is shipped without delay.

Major Assemblies Overview

Frame and Mount Plates

The ILT frame is the structural foundation of the tuckunder liftgate, supporting the lift arms, platform, and hydraulic components.

• Available finishes include black or galvanized, depending on corrosion requirements (Parts Manual, p. 6–7).
• Frame assemblies incorporate bushings, grease zerks, adjustable rubber snubbers, and mount plates for proper operation.
• Mount plate kits are offered as weld-on or bolt-on, with corresponding hardware and decals for torque specification (Parts Manual, p. 7).

Routine inspection of frame welds and bushings is recommended during maintenance intervals (Owner’s Manual 2016, p. 20–21).

Lift Cylinders

Palfinger ILT models use either Gravity-Down or Power-Down hydraulic cylinders:

• Gravity-Down Cylinder (P-2016765): uses internal valves and a 12 V release solenoid to lower under gravity (Parts Manual, p. 13).
• Power-Down Cylinder (40-1015-200): provides controlled lowering using dual-action hydraulic pressure (Parts Manual, p. 12).

Each cylinder includes bronze bushings (ELG1039), M10×1 grease fittings (EA-005), and a red protective cap (P-1191680). Regular lubrication extends service life.

Hydraulic Power Units (HPU)

The hydraulic power unit houses the pump, motor, oil reservoir, and solenoid valves.

• Post-2013 versions use a plastic reservoir with integrated pressure relief valve (Parts Manual, p. 22).
• Earlier versions used steel reservoirs and separate valve blocks (Parts Manual, p. 23–24).
• The HPU can be accessed by opening the curb-side cover, removing the retaining hardware, and sliding the unit out approximately 14–16 inches (Owner’s Manual 2016, p. 19).

Platforms

Two primary platform designs are available for the ILT series:

• All-Aluminum Platform: lightweight and corrosion-resistant (Parts Manual, p. 16–17)
• Steel/Aluminum Platform: steel main section with aluminum tip for added rigidity (Parts Manual, p. 18–19)

Each platform assembly includes the main and tip sections, torsion bar kit, hinge pins, and handle strap kit. Optional cart stops or walk-ramp extensions may be added for improved cargo handling.

Wear Parts and Consumables

Routine wear components must be monitored and replaced as needed:

• Pins and Bushings: Stainless steel pin kit (75-1018-100) and bushing kit (75-1018-200) maintain alignment of lift and parallel arms (Parts Manual, p. 9–11).
• Grease Zerks: M10×1 fittings (EA-005) and protective caps (P-1191680).
• Rubber Snubbers: Adjustable bumper pads (P-1128624) reduce platform vibration (Parts Manual, p. 7).
• Decals and Labels: Safety decals (ATG-series) must be visible and replaced if worn (Owner’s Manual 2016, p. 23–24).

Lubricate all pivot points every 500 cycles or approximately every three months (Owner’s Manual 2016, p. 21).

Optional Parts and Kits

Cart Stops and Ramp Extensions

Optional cart stop assemblies (22-0314-018) help prevent rolling cargo from leaving the platform. Each includes sliding rails, spring rods, and Delrin pads (Parts Manual, p. 20).

Dock extensions and walk ramps can be added for improved loading at varying dock heights.

Dock Bumpers

Dock bumper kits are available in multiple configurations to protect the liftgate from impact:

• 21-inch or 28-inch widths
• 3/16-inch heavy-duty or ¼-inch extra heavy-duty steel
• Weld-on or bolt-on designs with included hardware
• Finishes available in black or galvanized (Parts Manual, pp. 29–30)

Electrical Controls and Battery Box Kits

Electrical kits vary depending on truck or trailer installation:

• Battery Box Kits include a 150 Amp resettable circuit breaker, prewired harnesses, and connection hardware (Parts Manual, pp. 38–40).
• The liftgate operates via toggle switch or optional two-button hand-held remote (Owner’s Manual 2016, pp. 15–17).
• Circuit protection is provided by a 15 Amp inline fuse located on the solenoid and a master ON/OFF switch in the cab (Owner’s Manual 2016, p. 28).

Hydraulic Hoses

Replacement hoses differ between lift types:

• Gravity-Down Systems: Hose P-2021335 (1400 mm) and P-2021336 (2000 mm with 90° fitting) (Parts Manual, p. 25).
• Power-Down Systems (after 2019): Dual-hose routing with Tee Fittings (P-1232239) and Bulkhead Fittings (P-1111057) (Parts Manual, p. 26).

Conclusion

The Palfinger ILT tuck-under liftgate combines robust construction with precision-engineered hydraulic systems. By replacing worn liftgate parts with genuine OEM components, operators preserve the performance, safety, and longevity of their folding liftgate.
