Speed Limiter

The speed at which a piece of equipment travels plays a major factor in operator safety, load protection, equipment lifespan and lifetime cost. It also plays a large role in workplace-related injuries and equipment or building damage. It’s important to implement appropriate solutions such as Speedshield Technologies Speed Limiter to prevent unnecessary risk from occurring.

SLA Speed Limited by cable

Speedshield’s SLA speed limiter system is suitable for cable throttle vehicles. Unlike most conventional speed limiters, where fuel or spark is cut to prevent power and drive, Speedshield first converts the cable throttle system into an electronic pedal and actuator controlled throttle system allowing for full smooth electronic speed and acceleration control.

The result is a fully computer-controlled speed-limiting system that doesn’t harm the vehicle drive train, and can interact with Speedshield zoning accessories to provide variable speed con-
trol in different zones.
