Did you know that trucks aren’t just “big vehicles”? They come in a variety of shapes, sizes, and capabilities that can dramatically change how they’re used and how they impact the road.
If you own or manage a truck repair shop, understanding the classification of trucks is crucial to staying ahead in the industry. From light-duty trucks to heavy-duty trucks, each category has different requirements, repair needs, and parts.
Let’s explore the world of truck classification and uncover the key differences to help you provide the best service to your customers.
Understanding Truck Classifications and GVWR
When you look at trucks, you’ll notice they aren’t all built the same. The first thing that separates one truck from another is the weight. Classification of trucks primarily relies on Gross Vehicle Weight Rating (GVWR), which is the maximum weight a vehicle can carry, including its weight and cargo.
Understanding GVWR
Truck categories are not just about make, model, or year. They’re determined by the Gross Vehicle Weight Rating (GVWR), which is the combined weight of the vehicle and its maximum cargo load.
The GVWR takes into account several factors, such as the weight of the truck itself, the cargo it can carry, the number of passengers, and even the vehicle’s fuel capacity. Knowing a truck’s GVWR helps repair shops understand the type of services and tools required for repairs.
Legal and Licensing Considerations: Trucks with a GVWR over 10,000 pounds are required to have “Department of Transportation (DOT)” numbers and “Commercial Driver’s Licenses (CDL)” for drivers. Trucks with a GVWR over 10,000 pounds must follow strict rules, including the “Interstate Truck Driver’s Hours of Service laws”.
Class A CDL is required for trucks over 26,000 pounds with cargo over 10,000 pounds, whereas Class B CDL is for vehicles over 26,000 pounds towing less than 10,000 pounds, and Class C CDL is needed for hauling hazardous materials or passengers.
Safety Regulations and Compliance: Certain trucks are also required to stop at weigh stations for checks. As a truck repair shop owner, understanding these regulations allows you to provide better service and keep your customers compliant with the law.
Breakdown of Truck Classes
Here’s a breakdown of the different truck classes and their significance.
1. Light-Duty Trucks (Class 1-3)
Light-duty trucks are the backbone of daily transportation, often seen on city streets, highways, and construction sites. Whether for personal use, small business deliveries, or general work, these trucks are incredibly versatile and play a key role in the economy.
For truck repair shops, understanding the nuances of light-duty trucks is crucial, as they represent the largest segment of vehicles that require frequent maintenance.
GVWR Range
- Ranging from 6,000 to 14,000 pounds.
- Weight range includes a variety of vehicles, from small delivery vans to full-size pickups.
Common Examples
Pickup trucks: Pickup trucks are perhaps the most common type of light-duty truck on the road. They are used for everything from personal transportation to business logistics. These trucks are ideal for repairs involving engine work, brake systems, suspension, and routine maintenance.
Examples: Ford F-150, Ram 1500, and Chevrolet Silverado 1500.
Small vans or cargo vehicles: Small vans are perfect for businesses that require compact yet efficient vehicles for deliveries or carrying small cargo. These vehicles might need repairs related to the transmission, brake system, electrical components, and even custom fittings for cargo storage.
Examples: Mercedes-Benz Metris, Ram ProMaster City, and Ford Transit Connect.
Box trucks used for moving: Box trucks are commonly used by moving companies, delivery services, and small businesses that transport goods. These trucks have enclosed cargo spaces and are prone to wear in the suspension system, axles, and cargo doors. Specialized repairs might include maintenance of the box, lifting mechanisms, and engine services.
Examples: Isuzu NPR, Hino 195, and Mitsubishi Fuso Canter.
2. Medium-Duty Trucks (Class 4-6)
Medium-duty trucks are designed for more demanding jobs that require greater payload capacity and durability than light-duty trucks. These trucks are often used for local deliveries, transporting large passenger buses, or working in construction and service industries.
For truck repair shops, understanding the intricacies of medium-duty trucks is vital, as they represent a growing segment of the truck market and often require more specialized knowledge and parts.
GVWR Range
- Ranging from 14,001 to 26,000 pounds.
- Offer increased weight capacity and durability while still being manageable enough for local and regional work.
Common Examples
Larger cargo vans: These larger vans and chassis cab trucks are often used by businesses for transporting goods, equipment, or materials. With an increased payload capacity, these vehicles are a common sight in delivery fleets, construction, and moving services. Repair shops may encounter requests for work related to heavier suspension systems, brake components, and engine diagnostics due to the larger demands placed on these vehicles.
Examples: Freightliner M2, Ford F-650, and Chevrolet Silverado 6500HD.
Delivery trucks: Medium-duty delivery trucks are used by a variety of companies for transporting packages, food, and other goods. These vehicles are built for consistent, long-distance driving and may require more robust repairs. Common repair needs for delivery trucks include brake system maintenance, suspension repairs, and engine overhauls to handle the increased stress of frequent deliveries.
Examples: UPS Freight, International DuraStar, and Hino 268.
Bus fleets: Medium-duty buses are used for local public transportation, school buses, and charter services. These vehicles have specific repair needs due to their complex electrical systems, passenger safety features, and frequent stop-and-go operation. Common repairs for buses may include brake system repairs, AC and heating system maintenance, electrical system troubleshooting, and transmission service.
Examples: Bluebird Vision, Thomas Built Buses Saf-T-Liner, and IC Bus CE Series.
3. Heavy-Duty Trucks (Class 7-8)
Heavy-duty trucks are the true workhorses of the road, built to tackle the toughest jobs and carry the heaviest loads. These trucks are designed for extreme capability, offering unparalleled strength, power, and durability.
For truck repair shops, these trucks represent a unique challenge, as they require specialized repair skills and equipment to handle their more complex systems.
GVWR Range
- Ranges over 26,001 pounds.
- Primarily used for long-haul transportation, large construction equipment transport, and carrying heavy machinery.
Common Examples
Semi-trucks (18-wheelers): Semi-trucks are the backbone of the freight transportation industry. These massive vehicles are used for hauling goods across long distances and are typically seen on highways and interstates. They are complex machines that require regular maintenance, including engine diagnostics, brake system repairs, transmission services, and tire replacements. Due to the wear and tear from constant long-haul operations, semi-trucks often need extensive repairs on major components such as the engine, transmission, and differentials.
Examples: Freightliner Cascadia, Peterbilt 579, and Volvo VNL.
Dump trucks: Dump trucks are commonly used in the construction, mining, and waste management industries. These trucks are designed to carry heavy loads like sand, gravel, dirt, or debris and unload them with a hydraulic lift. Because of the extreme weight they carry, dump trucks experience heavy strain on their suspension systems, brakes, and hydraulic mechanisms. Repair shops often perform services like hydraulic system repairs, brake system replacements, frame inspections, and engine repairs.
Examples: Mack Granite, Kenworth T880, and Volvo VHD.
Logging trucks: Logging trucks are built to transport large quantities of timber from forests to processing mills. They are built to handle heavy, bulky loads and often travel on rough terrain. The high payloads and demanding working conditions mean logging trucks frequently require repairs on their drivetrain, suspension, and tires. As these trucks work in tough environments, chassis repairs, fuel system servicing, and engine overhauls are common repair needs.
Examples: Peterbilt 367, Volvo VNL, and Kenworth W900.
