This year has been economically challenging for businesses, particularly in the industrial and transportation sectors. With volatile fuel prices<\/a> and new tariffs, the transportation sector and heavy industry must adapt. At Ressorts Industriels Laval \/ C.T. CAM, we work with businesses to help them adapt. To do so, we focus on upgrading their existing vehicle fleets. <\/p>\n

We routinely perform chassis modifications for commercial fleets. Your vehicle\u2019s chassis is its backbone; it supports all of the vehicle\u2019s \u201crunning gear,\u201d including the engine, transmission, rear axle assembly in rear-wheel-drive vehicles, and all suspension components. Given the large number of components involved, modifying your chassis is more complicated than it seems. <\/p>\n

For companies that use heavy-duty vehicles, chassis modifications are an effective solution. Adapting existing vehicles for new tasks helps maximize their efficiency. In this article, we discuss why our corporate partners choose to order chassis modifications for their commercial fleets, as well as how a certified and specialized repair shop can help you make this transition. <\/p>\n

Useful terms<\/h2>\n

Also discussed in our article: What are the classes of heavy trucks in Quebec?<\/a><\/p>\n

Gross Vehicle Weight Rating (GVWR):<\/strong> refers to the maximum safe weight of a vehicle when fully loaded. This figure, calculated to ensure road safety, takes into account various weights, such as the vehicle itself, its passengers, and the equipment it carries. <\/p>\n

Heavy vehicles (Class 7):<\/strong> vehicles with a gross vehicle weight rating (GVWR) between 11,794 kg and 14,969 kg. Typically three or more axles. Includes municipal dump trucks, buses, moving trucks, etc. <\/p>\n

Heavy trucks (Class 8): <\/strong>vehicles with a gross vehicle weight rating (GVWR) exceeding 14,969 kg. Includes dump trucks, cement trucks, semi-trailers, and various specialized industrial vehicles. <\/p>\n

Heavy trucks (Class 9): Special-purpose vehicles with a gross vehicle weight rating (GVWR) exceeding 27,215 kg. This class is required for transporting special and oversized loads on highways. <\/p>\n

Safety inspection: <\/strong>Your vehicle must be inspected before any modifications are made, including a road test to check handling, cornering, and the absence of vibrations, etc. An alignment inspection would check the rear axle(s) and chassis to assess the vehicle\u2019s overall condition. <\/p>\n

Truck Chassis Modification for Commercial Fleets<\/h2>\n

Most commercial vehicles can be modified to meet the specific needs of each business. Heavy-duty vehicle chassis can be adjusted in length (by extending or shortening the chassis) or reinforced to change their payload capacity. <\/p>\n

For example, we can convert a semi-trailer chassis from 6 wheels to 10 wheels, and vice versa. This modification would allow for the modernization of the commercial fleet or an increase in the tonnage carried, without requiring a massive investment. <\/p>\n

Companies can take advantage of this type of modification to keep aging vehicles in service or to adapt to changing market conditions. A dump truck chassis, for example, can be shortened to reduce its capacity, but also to lower its fuel consumption. <\/p>\n
