Truck Roller Brake Tester with integrated Lifting Bed Load Simulation
EquipSpecs supplies and installs the Ryme Worldwide FRU 4, a truck roller brake tester designed for brake testing of light and heavy vehicles with axle loads of up to 20 tonnes, featuring fully integrated lifting bed load simulation.
What is the FRU 4 Roller Brake Tester?
The FRU 4 is a premium truck roller brake tester widely used in NZ heavy vehicle workshops and COF inspection lanes.
Bringing fast, efficient, and reliable operation together with an intuitive user interface, it measures:
- Braking force on manual and pedal brakes
- Rolling resistance
- Ovality
- Braking performance
The FRU 4 is compatible with both new workshop installations and existing workshop pits. EquipSpecs handles the full process — installation, integration, commissioning, calibration, and aftersales support across New Zealand.
