MTU-GLR Model & Specification Overview: Capacities, Platforms, and Bed Heights

The MTU-GLR family includes multiple tuck under liftgate configurations designed to match a wide range of truck applications, bed heights, and cargo-handling needs.

This article provides a strictly specification-focused comparison of the MTU-GLR, MTU-GLR-WR, and MTU-GLR-EX models, covering capacities, platform options, bed height requirements, standard features, and available factory options.

Documentation Resources from Anthony

Information in this article is sourced from Anthony MTU-GLR manuals and brochures, as well as the LiftGateMe team expertise. Always refer to your specific liftgate’s manuals for complete procedures and serial number, model, and year-specific details.

Reference PDFs used:

• Anthony MTU-GLR Installation Manual
• Anthony MTU-GLR Operation Manual
• Anthony MTU-GLR Brochure (2014)
• Anthony AST Installation Manual

Capacities

This section compares the lifting capacities of both Anthony MTU-GLR and Anthony MTU-WR models using only brochure-verified data.

GLR Capacities (2014 Brochure)

The MTU-GLR brochure lists the following lifting capacities:

• 2500 lb (MTU-GLR-25)
• 3000 lb (MTU-GLR-3)
• 4000 lb (MTU-GLR-4)
• 5000 lb (MTU-GLR-5)
• 6000 lb (MTU-GLR-6)

WR Capacities (2016 Walk-Ramp Ready Brochure)

WR models offer:

• MTU-GLR-WR-3 — 3000 lb
• MTU-GLR-WR-4 — 4000 lb

Platform Material Limitations

According to the MTU-GLR brochure, the all-aluminum 80" × 60" wedge platform is not available on MTU-GLR-6 (6000 lb model).

As described above, GLR models cover a wide range from 2500–6000 lb, while WR models top out at 4000 lb. The only material limitation is that MTU-GLR-6 cannot use the all-aluminum wedge platform.

Bed Height Requirements

Bed height compatibility is critical when selecting a tuckunder liftgate. This section summarizes only the verified height ranges from brochures and the Installation Manual.

Standard MTU-GLR Bed Heights

The 2014 brochure lists the same range for all capacities: 47" – 57" bed height range (all GLR models).

Walk-Ramp (WR) Bed Heights

WR models have a slightly higher minimum: 49" – 56" bed height range (WR-3 and WR-4).

Installation Manual Minimum & Maximum Requirements

The Installation Manual confirms:

• Minimum bed height fully loaded:
• GLR models: 47"
• WR models: 49"
• Maximum bed height empty (all models): 57"

Ground Clearance Chart Summary

The Installation Manual provides ground clearance (B) relative to bed height (A).

Example values (full chart spans 47"–57"):

• At 47" bed height → 15-3/8" clearance
• At 57" bed height → 25-3/8" clearance

GLR models have broader compatibility (47–57"), while WR models require a slightly higher frame (49–56"). These ranges should always be checked against the installation manual.

Platform Options

Platform design is a major differentiator among MTU-GLR variants. This section summarizes verified dimensions and material configurations.

Standard GLR Platform Options (2014 Brochure)

Two platform types are listed:

• Steel Main / Aluminum Flip, 80" × 60" wedge
• All-Aluminum 80" × 60" wedge
• Not available on MTU-GLR-6

Walk-Ramp Ready (WR) Platform

WR models use:

• All-Aluminum 80" × 60" wedge platform only

Wedge Platform Characteristics

The wedge design provides easier loading by creating a tapered entry surface, described in both brochures as follows:

• “Wedge platform… provides easy, secure loading” (GLR)
• “Large wedge design provides plenty of space and easy loading” (WR)

Across the MTU-GLR liftgate family, the standard dimension is 80" × 60", with steel/aluminum hybrid and all-aluminum options depending on the model. WR units use the all-aluminum wedge exclusively.

Standard Features Across Models

In both brochures, Anthony outlines several shared standard features that define the MTU-GLR family.

Standard Features Verified in the GLR Brochure

• CHS – Centralized Hydraulic System (stainless pump box)
• Power Down operation for consistent cycle times in all weather
• Service-Free Bushings with lifetime warranty at pivot points
• Mechanical Safety Latch (HD design)
• Dock Bumpers (Max Duty) for floor extension protection
• 3-Year Mechanical, Electrical & Hydraulic Warranty (industry-leading)

Standard Features Verified in the WR Brochure

In addition to the above, WR models include:

• Walk-Ramp Ready design enabling ramp access without lowering liftgate
• Premium Polymer Finish (instead of powder coat shown for GLR)

Differences Between 2014 (GLR) and 2016 (WR) Literature

• Finish:
• 2014 GLR: “Anthony 3-Step Powder Coat” finish
• 2016 WR: “Premium Polymer Finish”
• Platform Availability:
• WR: only all-aluminum wedge
• GLR: hybrid or all-aluminum (restrictions apply)

All MTU-GLR models include the same core structure—CHS pump system, power-down, mechanical safety devices, and long-term bushings—while finish and platform compatibility vary by model year and configuration.

Optional Equipment

Both brochures list optional configurations that may be added to tailor a tuckunder liftgate for specific fleet needs.

GLR Options (2014 Brochure)

• Wireless, removable corded, flush-mount, or dual controls
• Stainless steel toggle guard
• Stainless steel battery box
• Trail/solar charger
• Third step add-on for dock bumper
• Galvanized finish with extended warranty
• ICC bumper (trailer certified)
• Ignition cut-off switch
• Trailer sub-frame kit
• Dual foot-operated cart stops

WR Options (2016 Brochure)

Most options are the same, with slight wording updates:

• Wireless, removable, corded, flush-mount, or dual controls
• Stainless steel toggle guard
• Stainless steel battery box
• Auxiliary power systems
• Third-step dock extension
• Galvanized finish
• ICC bumper
• Dual cart stops

Also, the Installation Manual includes additional optional details, such as optional DOT tubular bumpers and alternate floor extensions. These are installation-only components and not general model specs, so they are included here only as confirmation that they exist.

GLR and WR models offer a nearly identical range of factory options, making customization straightforward regardless of capacity class.

Conclusion

The Anthony MTU-GLR series provides a flexible lineup covering capacities from 2500 to 6000 lb, multiple platform materials, and compatibility with bed heights ranging from 47–57 inches. WR models support walk-ramp integration and feature all-aluminum platforms with a higher minimum bed height requirement. All models share Anthony’s core structural and hydraulic design elements—including CHS, power-down operation, and lifetime service-free bushings—making them reliable solutions across medium-duty and heavy-duty truck applications.
