Introduction to the ILP Pallet Pro Series

The ILP Pallet Pro series is a part of Palfinger’s tuck under liftgate lineup, specifically engineered for commercial trucks and trailers transporting palletized or carted cargo. Designed with user-friendly features and dependable construction, both the ILP 25 and ILP 33 deliver value and flexibility in freight handling.

Pallet Pro lift gates are ideal for operations that require a tuck-away liftgate with level ride and stable platform performance. These models serve a wide installation range — from Low Pro chassis to full-size trucks — making them a versatile choice for many vehicle types.

Lifting Capacity and Platform Sizes

Both ILP 25 and ILP 33 are optimized for different weight handling requirements, allowing buyers to choose based on cargo needs.

Lift Capacities

• ILP 25: Rated at 2,500 lbs.
• ILP 33: Rated at 3,300 lbs.

These capacities are measured at a 24-inch load center from the bed extension. As noted in the Owner’s Manual, capacity decreases as the load is moved further from this center point.

Platform Sizes

Each model is available with multiple platform lengths:

• 48" platform (80" width)
• 54" platform (80" width)
• 60" platform (80" width)

The consistent 80" platform width across all sizes ensures compatibility with standard cargo widths.

Bed Height Compatibility

Bed height compatibility ensures the liftgate can properly store and deploy across different truck types.

Install Range

• Compatible with bed heights from 38" to 55"
• Laden minimum: 38"
• Unladen maximum: 55"

Platform-specific install details:

• 48" platform: 38" to 52"
• 54" platform: 42" to 55"
• 60" platform: 45" to 55"

All platform sizes are available with longer lift arms to reach the full 55” bed height if needed.

Weight and Construction

Choosing between aluminum and steel platforms helps balance unit weight with durability preferences.

Platform Materials

• Available in both steel and aluminum
• Steel options are typically heavier and more rugged
• Aluminum offers weight savings and corrosion resistance

This allows for tailored configurations depending on fleet vehicle weight restrictions and operational priorities.

Design Features That Add Value

The Palfinger ILP Pallet Pro models include a suite of features engineered for reliability, control, and smooth operation in demanding environments.

Standard Performance Enhancements

• Dual torsion springs: assist both the main and folding sections of the platform
• Adjustable parting rollers: reduce friction for easier folding
• Unique leveling joint: ensures platform stays level without dragging

Hydraulic System Highlights

• Mid-arm two-cylinder design: maximizes platform stability while minimizing weight
• Hydraulic cylinder locks: provide greater control and safety
• Aerospace-grade hydraulic fluid: used standard (Hydrex MV Arctic 15)
• Offers wide temperature tolerance: -49°F to 73°F

These engineering choices make the ILP series not only easy to operate but also durable across diverse operating conditions.

Mounting Clearance and Vehicle Compatibility

The ILP series is designed to fit a wide range of truck types and chassis configurations.

• Mounting clearance ranges from 24" to 37", depending on platform size and installation specs.
• Fits everything from low-profile chassis to standard-height commercial trucks
• Multiple lift arm lengths available to expand vehicle compatibility

This installation flexibility makes the ILP Pallet Pro series suitable for mixed-use fleets and varied body styles.

Load Distribution and Safe Capacity Use

For safe and optimal performance, it's critical to understand how load placement affects lifting capacity.

• The rated capacity is based on a 24" distance from the truck body to the center of the load.
• Capacity decreases the farther the load is placed from the vehicle
• A load diagram in the manual shows a clear drop in effective capacity as distance increases — helpful for operators planning heavier freight placement

This data helps ensure safe operation and protects the liftgate’s mechanical integrity under varying cargo conditions.

Conclusion

Like other Palfinger liftgates, the ILP Pallet Pro series — including the ILP 25 and ILP 33 — provides robust lifting capacities, flexible platform sizes, and advanced stability features for a wide range of commercial vehicles. Whether you need a lightweight aluminum option or a rugged steel platform, these tuck under liftgate models are engineered for reliability, safety, and performance.
