The advantage of tipper semi-trailers over standard tippers is larger capacity of the body, which enables a semi-trailer to transport up to 2 times as much cargo as a truck does.
The choice between new and used tipper semi-trailers depends on the operating conditions and the cargo type.
- number of axles
The majority of tipper semi-trailers have either 2 or 3 axles. The average payload capacity is 25-35 tonnes. The chassis of present-day tipper vehicles features air suspension and a reinforced frame.
- body: shape and material
There are rectangular and oval bodies with closed and open box configurations. A rectangular body is a multi-purpose one. It is used to transport bricks, blocks and other solid cargo as well as bulk cargo. An oval body in its turn doesn’t have welds. Thus, it can boast lighter weight and greater stability during handling operations.
As for material, there are aluminium and steel models. The former are much more expensive than the latter ones. But an aluminium semi-trailer pays for itself in short time period due to its light weight and fuel economy. However, in case of solid loads the best variant is to use a steel body.
- unloading mechanism
Tipper semi-trailers are made with either back or side dumping system. Back dumping is often carried out by means of hydraulic lift in the open air. What concerns side system, it is widely used in agricultural sphere for unloading indoors.
Besides, some tipper semi-trailers can be equipped with additional attachments such as protective canopies, rock fenders, etc.
The German Schmitz Cargobull AG is a steady leader in the European market of trailers and semi-trailers. Other significant representatives in this market segment are Langendorf GmbH, the French company Behalu (one of the leading manufacturers of aluminium vehicles) and the international brand Fruehauf.
