Ride control system (RCS)
Depending on the machine's operating weight,
road conditions, and speed, there may be pitching
oscillations when driving wheel loaders.
The ride control system reduces pitching
oscillation, which results in the following
advantages:
• higher transport speed
• improved material-handling performance
• more stable steering performance
• shorter braking distance
• increased ride comfort
Load-retaining valves (option) are without
function as long as the ride control
system is activated!
Operation
20 km/h version
• Operate the ride control system toggle switch
(80/11).
The green indicator lamp lights up.
High-speed version
• The ride control system is automatically
activated as soon as the travel speed is more
than 6 km/h.
The bucket tilt cylinder must not be at a
cylinder stop (bucket not completely tilted
back) as otherwise free oscillation is not
possible.
Repair
Before working on the loader hydraulic
system, the accumulator pressure of the
ride control system must be let off. To do
so:
• Stop the machine in the proper
manner.
• Switch off the RCS (80/11).
• Control block for RCS is installed in
rear-end.
• Slacken counternut and adjusting
screw (81/1), the accumulator
pressure is reduced.
