Steering interlock valves for trucks

In underground mining, where space is tight and consequences are severe, unintended movement can be fatal. The interlock system is a critical life-saving safety feature.

Description

The new Toro® TH430 B Gen dump truck has interlock valves added to the steering lines outside the cabin.

The hydraulic pipes have been updated to include the new interlock valves. The interlock valves lock the steering when the machine stops. They also lock the steering when the cabin door is open.

The center articulation creates a crush zone. Sudden steering movement can trap or seriously injure someone between the front and rear frames. A steering interlock that locks steering when the truck stops or when the cab door is open is essential because it:
•Prevents unintended articulation or wheel movement
•Protects workers from crush injuries
•Eliminates hydraulic drift hazards
•Ensures compliance with safety regulations
•Protects equipment components

In underground mining, where space is tight and consequences are severe, unintended movement can be fatal. The interlock system is a critical life-saving safety feature.

The interlock valves are retrofittable to machines in the previous TH430.
