Trailers
& Semi Trailers are increasingly fitted with pneumatic air suspension to
ease the transport of fragile goods and to protect the vehicle body. Shock
Absorbers designed for these application are characterized by high load
carrying capacity and having large spring deflections. By installing
pneumatic air suspension shock absorbers in the trailers, the jerkings and
bounces can be drastically reduced. The towing capacity of the trailers also
increases.
Trailer Shock Absorbers Installation
The installation of shock absorbers in the trailers is simple. A few steps
of installation are as follows:
- Determine the type of the frame, means what are the features of the
existing frame.
- Determine the axle diameter, i.e leaf springs. Also determine the
trailer suspension specific GVW rating.
- Based upon the derived values from the above step, collect the
suitable retrofit kit.
- Fixed the upper mounting location and measure the distance between
the upper mounting and lower mounting on the basic of the centerline
dimension at the static height of the vehicle.
- Determine the dimension and it should be measured on the level
surface with the trailer.
- On the basic of the values obtained from step 4 and 5, the most
appropriate shock absorbers should be selected.
Installation tips of Trailer Shock Absorbers
The installation process of the shock absorbers in the trailers is simple
and no welding and no special tools are required. The trailer or semi-tailor
should be emptied during the installation of shock absorbers in it. By
extending and contracting these shock absorbers, their full length should be
measure before welding the steel mounts in the middle of the measurement.
This process will ensure very long travel for the loaded and empty trailers.
The shock absorbers for trailers come in a complete kit, that comprises of
nuts, box with bolts and washers.
Features
of Trailer Shock Absorbers
- Shock absorbers used for trailers and other heavy vehicles should be
engineered to withstand heavy load and stress applied by the vehicles.
These shock absorbers should also possess pneumatic suspensions.
- These should have the ability to absorb shocks consistently even at a
very high temperature and in all conditions. Therefore, the modern shock
absorbers consist of hydraulic fluid (range in between of -40°C to
+40°C) and high temperature resistant sealing system.
- There are high durability bushing systems present in these shock
absorbers, which increase the life of the shock absorbers and also make
the installation easier.
- The shock absorbers are designed in such a way, so that these can
enhance the comfort during driving.
