Semi-trailer checklist: items, model and frequency

A semi-trailer checklist is a tool for fleets seeking to keep better track of semi-trailer inspections and organize transport operations.

This list contains items that must be assessed to identify faults, wear and breakdowns in important vehicle components. This speeds up corrections, improves maintenance routing and helps reduce fleet maintenance costs.

What is a semi-trailer checklist?

A semi-trailer checklist is a list of items to inspect on both the vehicle's body and tractor unit. Although it is possible to create a specific checklist for the tractor unit and another for the body, it is also feasible to use a single checklist for the complete tractor-trailer combination.

Despite the different semi-trailer types, you can use one checklist for all inspections, provided no important component is missing and you offer an “NA” (not applicable) response option for use where appropriate. This marking is important when a single model includes items that apply to only one part of the combination being inspected.

The importance of a semi-trailer checklist

You need to use a vehicle checklist in your fleet; that is beyond question. It promotes efficient organization of the process and allows you to keep track of the condition of semi-trailers.

This speeds up the identification and resolution of issues with the fleet's semi-trailers, improving the scheduling of servicing, cleaning and other corrective services. When the list makes it clear when an item does not apply to a particular configuration, the team avoids confusing records and routes each reported issue more effectively.

This approach brings advantages that fleet managers greatly value, from reduced operating costs to increased productivity and meeting operational deadlines.

How to create a semi-trailer checklist?

Creating a semi-trailer checklist starts with identifying which semi-trailer components the driver should inspect.

This generally includes items such as radiator water level, brake pressure and the operation of vehicle lights, among others. If the document also covers the tractor unit, it is worth naming fields clearly and keeping the “not applicable” option for items that do not make sense in a particular inspection.

After identifying these components, you can choose the checklist type to use, whether paper or digital.

This choice will determine your next steps.

If you choose paper, you will have to create a document, include all the necessary fields and print the number of forms according to the number of semi-trailers and drivers in your fleet, as well as the number of inspections to be performed each day.

If you choose a digital checklist, you can use a ready-made model from your checklist platform and customize it as needed. Another alternative is to create a customized checklist from scratch, keeping clear fields for each item and the “not applicable” alternative when the model is used for more than one vehicle configuration.

After that, each driver can access the models through the mobile app and perform the inspection whenever and wherever needed.

Which items should a semi-trailer checklist include?

Although the main items are external, it is equally important to consider the semi-trailer's internal components for inclusion in the inspection.

It is also essential to identify how often the checklist will be completed, to determine which items should be included in daily inspection and which should be covered in periodic assessments, according to your fleet's specific needs.

Here are some of the main items for a semi-trailer checklist:

Lights

• Turn signals;
• Brake lights;
• Reversing lights;
• Hazard lights.

Suspension

• Shock absorbers;
• Springs;
• Balancing;
• Alignment.

Brakes

• Front, where applicable to the model inspected;
• Rear, where applicable to the model inspected;
• Pads, when this item is part of the vehicle inspected.

Box body

• Hinges;
• Locks;
• Lifting system.

Safety

• Reversing alarm;
• Horn, where applicable to the model inspected;
• Reflective strips.

Tires

• Calibration;
• Wear;
• Spare tire.

Accessories and equipment

• Warning triangle;
• Fire extinguisher;
• Jack;
• First-aid kit.

Besides creating your own checklist, you can also download a ready-to-use semi-trailer checklist model for free (in Portuguese).

How to use a semi-trailer checklist?

Semi-trailer checklists can be created based on time periods or mileage traveled. A transport fleet normally uses daily checklist, six-monthly and annual models.

However, it is important to consider the due date conditions specified in the model the fleet uses. For example, if the six-monthly checklist adopted by the operation also has a limit of 10 thousand kilometers, inspection must take place before six months when the semi-trailer reaches that mileage in a shorter period. This helps ensure safety and proper maintenance of the fleet's vehicles.

It is important to remember that proper use of this checklist type is essential to ensure inspections are effective and issues are identified and corrected in time, preventing serious and costly failures in your fleet.

Can technology help with semi-trailer inspection?

Absolutely! Technology has positive impacts in several areas of fleet management, and semi-trailer inspection is one of them. In this case, by using a fleet maintenance management system and an electronic semi-trailer checklist.

When integrated, these technologies provide precise and appropriate control over the condition of your fleet's semi-trailers. In systems with this feature, digital records can also generate reports and open work orders from the reported issues logged during inspections.

In addition, digital checklists can be a convenient option for drivers and fleet managers, allowing the information entered during inspection to reach the team responsible for maintenance and necessary repairs more quickly.

Discover a technology solution for your fleet and use a digital semi-trailer checklist to speed up and simplify the routine of your transport operations.
