All about Waltco RGL Series Liftgate

The Waltco RGL Rail Lift is a rail liftgate designed for consistent, vertical lifting of cargo on trucks and trailers. With multiple configurations and capacities ranging from 2,000 to 6,000 lbs, the RGL series was built to handle a wide range of freight applications.

This model is no longer in production and has been replaced by Waltco’s newer MDV rail lift series, but it remains widely used in fleets across America that require dependable rail lift performance.

At its core, the RGL uses dual vertical rail assemblies, runner systems, and hydraulic lifting components to move the platform smoothly between ground level and bed height.

Key Features of the Waltco RGL Rail Lift

The RGL series includes several design elements that support reliable operation and long-term use:

• Rail-Type Lifting Design:  The platform travels vertically along fixed rails mounted to the rear of the vehicle, providing stable lifting motion.
• Wide Capacity Range (2,000–6,000 lbs): Multiple model configurations allow the liftgate to match different load requirements.
• Hydraulic Power System: Includes a hydraulic unit, reservoir, solenoid valves, and lift cylinders to control raising and lowering functions.
• Runner and Cable System: The lift operates using runner assemblies, pulley systems, and lifting cables that guide platform movement.
• Platform Brake Mechanisms: Designed to help control and stabilize platform movement during operation.
• Deck and Extension Options: Platform configurations include deck assemblies and optional extensions to support different loading needs.

These components work together to provide controlled lifting, stability, and repeatable performance across operating cycles.

How the RGL Rail Lift Operates

The RGL liftgate is designed specifically for loading and unloading cargo, moving freight between ground level and the truck bed.

Basic operation includes:

• Opening the platform into loading position
• Lowering the platform to ground level
• Raising the platform to bed height
• Closing the platform for transit

The liftgate must operate smoothly and evenly throughout the full cycle, without unusual noise or vibration.

The system relies on:

• Hydraulic pressure for lifting and lowering
• Rail-guided runners for vertical travel
• Control switches for operator input

Proper use ensures safe and efficient cargo handling.

Installation and Vehicle Requirements

The RGL series requires specific vehicle conditions for proper installation and operation.

Key Requirements:

• Bed Height Compatibility: Typical bed height ranges depend on platform size and configuration, generally falling between 36” and 60”, depending on setup.
• Side Wall Strength: Vehicle side walls must support lifting forces up to:
• 2,000–3,000 lbs (RGL-20/30)
• 2,500–4,000 lbs (RGL-40)
• 3,000–5,000 lbs (RGL-50)
• 3,500–6,000 lbs (RGL-60)
• Door Compatibility: The RGL cannot be installed on vehicles with swing-type rear doors that interfere with liftgate operation.
• Mounting Structure: The liftgate must be securely welded to the vehicle’s rear sill and corner posts, with proper alignment and reinforcement.

Proper installation is critical—incorrect mounting can lead to unsafe operation or equipment failure. Find liftgate installation near you here.

Maintenance and Inspection Overview

Routine inspection and maintenance are essential for safe operation and long-term performance.

Regular Checks Include:

• Inspecting structural components for cracks, wear, or deformation
• Checking hydraulic cylinders and hoses for leaks
• Verifying cables are free of damage or wear
• Ensuring smooth runner movement along rails
• Confirming proper function of controls and safety devices

The manual emphasizes that inspections and repairs should be performed by qualified personnel only. Find liftgate repair near you here.

Lubrication should be performed periodically, including:

• Chassis grease on moving contact points
• Light lubricant on linkage and brake components

Routine maintenance helps prevent downtime and extends the life of the liftgate.

Replacement Parts and Service

When servicing the Waltco RGL Rail Lift:

• Always use Waltco OEM replacement parts
• Provide the model and serial number when ordering parts
• Avoid using non-OEM components, as they are not interchangeable

This ensures proper fit, safety, and compatibility with the liftgate system.

RGL Rail Lift: Discontinued but Still in Service

While the Waltco RGL Rail Lift is no longer manufactured, it remains a common liftgate in existing fleets.

For new applications, Waltco has replaced the RGL series with the MDV rail lift, which incorporates updated design features and improvements.

However, for operators maintaining existing equipment, understanding the RGL’s design, operation, and maintenance requirements is essential for keeping these liftgates running safely and efficiently.
