Pre-Inspection Setup

Before checking the liftgate, Maxon instructs the operator to park the vehicle on flat ground and set the parking brake (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Key Setup Steps

• Park the vehicle on flat, level ground
• Set the parking brake before inspection begins

Starting with the vehicle properly parked is part of Maxon’s recommended daily operation checks and establishes the correct condition for the rest of the inspection (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Operator Positioning and Awareness

Maxon’s daily checks begin with the electrical system and battery condition before liftgate operation (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Inspection Checklist

• Confirm batteries are fully charged
• Check that battery terminal connections are clean and tight
• Inspect the battery box for damage
• Verify the cab cutoff switch is ON, if equipped

These items are listed directly in the recommended daily operation checks (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

The maintenance manual also says to check batteries for load condition, corrosion, cables, hold-downs, and water level during preventive maintenance, which supports the need to pay attention to battery condition and cable integrity (Maxon-BMR-Maintenance-Manual-rev-D-2024.pdf, p. 15).

What to Look For

• Corrosion at battery terminals
• Loose battery terminal connections
• Damage to the battery box
• Cab cutoff switch not set correctly, if equipped

Hydraulic System Inspection

Operators must visually check the pump cover, inspect for hydraulic fluid leaking from the pump box, check for fluid leaks from hydraulic cylinders, and follow hydraulic hose routing from the cylinders to the pump box (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Inspection Checklist

• Check that the pump cover is latched securely and is undamaged
• Look for hydraulic fluid leaking from the pump box
• Inspect hydraulic cylinders for leaks
• Follow the hydraulic hose routing from the cylinders to the pump box
• Make sure all hoses are connected at both ends
• Check for cracks, chafing, and fluid leaks in the hoses

These points are stated directly in the daily inspection section of the Operation Manual (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

The Maintenance Manual also instructs users to check hoses and fittings for chafing and fluid leaks and replace if necessary (Maxon-BMR-Maintenance-Manual-rev-D-2024.pdf, p. 14).

What to Look For

• Oil or wetness around the pump box
• Hydraulic fluid on or around cylinders
• Cracked or chafed hoses
• Loose hose connections

Structural Component Checks

Maxon’s daily checks include a visual inspection of the main structural components of the liftgate (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Inspection Checklist

• Check the main frame for cracks and bends
• Check the extension plate for cracks and bends
• Check the columns for cracks and bends
• Check the runners for cracks and bends
• Check the platform openers for cracks and bends
• Make sure platform chains are undamaged and connected securely at both ends
• Make sure all bolts and pins are in place and undamaged

These requirements come directly from the Operation Manual’s recommended daily operation checks (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

The Maintenance Manual also says never to operate the liftgate if parts are loose or missing and includes checks for loose or missing nuts, bolts, covers, roll pins, screws, and pins, along with checks for cracked welds and damage to columns, runners, and platform (Maxon-BMR-Maintenance-Manual-rev-D-2024.pdf, pp. 14-15).

What to Look For

• Bent columns or runners
• Cracked structural members
• Missing pins or bolts
• Damaged or improperly connected platform chains

Control System Verification

Maxon instructs operators to visually check that standard and optional controls are in place and undamaged before operating the liftgate (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Inspection Checklist

• Confirm all standard controls are in place
• Confirm that optional controls are in place, if equipped
• Check that controls are undamaged

The Operation Manual also identifies the standard control locations, including the ground-access column switch and the platform-access runner switch on the right-hand runner (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 12).

If equipped, power-down buttons are shown on the column switch and runner switch (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 13).

What to Look For

• Broken switch housings
• Missing controls
• Visible damage to switch assemblies

Platform and Surface Inspection

Maxon’s daily checks include both the cleanliness and the structural condition of platform-related surfaces (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Inspection Checklist

• Make sure load-carrying surfaces on the extension plate are clean
• Make sure load-carrying surfaces on the platform are clean
• Make sure load-carrying surfaces on the flipover are clean
• Make sure the retention ramp is clean if equipped
• Check for no oil, debris, or corrosion on those surfaces
• Inspect the platform and flipover for cracks, holes, and bends
• Inspect the platform and flipover for cracks, holes, and bendsMake sure retention ramps and cart stops, if equipped, are undamaged and operate smoothly

These points are stated directly in the Operation Manual’s daily check section (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

What to Look For

• Oily or dirty walking and loading surfaces
• Corrosion on load-carrying areas
• Cracks or holes in the platform or flipover
• Damaged or sticking retention ramps or cart stops

Functional Operation Test

After the visual inspection, Maxon instructs operators to use the operation instructions in the manual to unfold the platform, lower it to the ground, and run the liftgate through one cycle without a load (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, pp. 8-9).

Test Procedure

• Use the operation instructions to unfold the platform
• Lower the platform to the ground
• Operate the liftgate through one full cycle without a load on the platform
• Raise the platform to vehicle bed height
• Lower the platform to ground level

Operators should also check for smooth operation as the platform unfolds and as the runners lower the platform to the ground (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

What to Verify

• Smooth operation as the platform unfolds
• Smooth lowering to the ground
• Proper no-load cycling from ground level to bed height and back down

Noise and Performance Indicators

Maxon specifically instructs operators to listen for unusual noises and look for jerking motion or uneven movement during the no-load operating cycle (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 9).

Inspection Checklist

• Listen for unusual noises
• Look for jerking motion
• Look for uneven movement at the left-hand and right-hand sides of the platform
• Confirm uneven movement does not exceed 1 inch

The warning section of the Operation Manual says a correctly installed liftgate will operate smoothly and reasonably quietly, and that scraping, grating, and binding noises should be corrected before continuing operation (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 6).

The Maintenance Manual also states that unloaded platform movement in gravity down or power down modes should have a maximum side-to-side runner difference of 1 inch (Maxon-BMR-Maintenance-Manual-rev-D-2024.pdf, p. 22).

What to Look For

• Scraping noises
• Grating noises
• Binding noises
• Jerking motion
• More than 1 inch of uneven side-to-side movement

When to Remove Liftgate from Service

Maxon states that if any of the operation checks reveal a need to service or repair the liftgate, the liftgate should not be operated until a qualified mechanic services or repairs it (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Do Not Operate If:

• The inspection shows a need for service or repair
• Hydraulic fluid leaks are found
• Controls are damaged or missing
• Structural damage, such as cracks or bends, is found
• Hoses are cracked, chafed, leaking, or disconnected
• Abnormal operating movement or noises are observed

This standard is explicit in the Operation Manual and is the proper threshold for removing the liftgate from service during a daily inspection (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).

Conclusion

A daily inspection routine for a column liftgate should follow the manufacturer’s recommended checks before the liftgate is used. For the Maxon BMR column liftgate, those checks include battery condition, hydraulic leaks, hose condition, structural inspection, control verification, surface condition, and a no-load operating cycle (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, pp. 8-9).

Using a consistent Maxon BMR checklist helps identify service needs before operation. If the inspection shows any condition requiring service or repair, the liftgate should not be operated until it has been repaired by a qualified mechanic (Maxon-BMR-Operation-Manual-rev-C-2024.pdf, p. 8).
