The difference between light and heavy leaf springs is the amount of weight they can withstand.
Heavy leaf springs, as the name suggests, are designed to carry heavier loads than light leaf springs.
In turn, they are usually found on larger, HGVs (Heavy Goods Vehicles) like lorries which – with the right equipment – can withstand up to 44 tonnes.
Alternatively, light or standard leaf springs are typically installed on LCVs (Light Commercial Vehicles) like vans, which can withstand up to 3.5 tonnes.
Yes, there are two main types of leaf springs: mono leaf springs and multi leaf springs.
Mono leaf springs feature a single layer of metal without any additional plates, whilst multi leaf springs feature multiple metal plates fixed together to create a stack.
Whilst both vehicle support vehicle suspension systems, multi leaf springs are more popular amongst commercial vehicles as they offer greater strength and durability.
There are several benefits to using a leaf spring suspension system, some of which include:
Durability – due to their layered design, leaf springs are incredibly long-lasting and can comfortably withstand heavy loads for hundreds of thousands of miles.
Versatility – leaf springs can be modified and designed to meet manufacturers specifications for a wide variety of vehicles including vans, trucks, trailers and lorries.
Cost-efficiency – with their simple yet effective design, leaf springs are incredibly cost-effective as they are reliable and relatively easy to
Comfort – leaf springs ensure a smooth ride when transporting heavy loads – even when encountering uneven roads and potholes.
Safety – leaf springs optimise your vehicles performance by ensuring your tyres are aligned, your vehicle is at an even height and steering is unimpaired.
Provide different types of leaf springs which include conventional multi leaf springs, parabolic leaf springs, air linkers and sprung drawbars.
In terms of vehicle types, it include heavy duty semi trailer leaf springs, truck leaf springs, light duty trailer leaf springs, buses and agricultural leaf springs.
