Automated load control to avoid overload on the fifth wheel

Measures the weight on the trailer axles and automatically lifts the last axle of the trailer if the first and second axles are not fully loaded

Automatically respects the total permitted weight per trailer axle

Helps to optimize load distribution to its maximum allowed capacity

Reduces risk of damage to the truck's drive axle caused by overload 

Helps to avoid penalties from overload on truck’s drive axle

A pressure sensor positioned at the tag axle continually measures the actual pressure in the tag axle bellows

Helps to save repair costs by avoiding bouncing, oscillating and cramping of air bellows 

Reduces the number of components required to monitor and maintain pressure levels

Can be retrofitted up from Premium TEBS E2


Forklift Control

Enhances trailer stability while driving
