Simret 4000 Heavy vehicle brake tester

Turnkey Instruments Ltd Stand: PD1

The instrument is ideally suited to the brake ratio method of testing, which is recommended as best practice for rubber-tyred vehicles in quarries, open cast coal sites and mines.

The Simret 4000 records average brake ratio, test incline, speed and stopping distance, and because the brake ratio is measured independently of gradient and speed, tests can be carried out in different environments and conditions.
