Hydraulic system
The following pages contain a brief description of the hydraulic components and assemblies that are on the feeder breaker.
The primary hydraulic system for this machine has been designed to provide hydraulic power for the conveyor drive motor, tram motors, tilt cylinders and lift cylinders.
The secondary hydraulic system for this machine has been designed to provide hydraulic power for the belt spreader cylinders, roof cylinders, the foot cylinders, and the tailpiece cylinders
WARNING! This section is intended only to familiarize the user with the hydraulic components of the feeder breaker. All hydraulic maintenance should be performed only by a qualified technician with the knowledge of the function of the components involved.
WARNING! Never disconnect a hydraulic hose if the circuit is pressurized or if there is a load on the circuit. If a hose is disconnected while the circuit is pressurized or a load is on the circuit, the load will fall causing damage to the machine or serious injury or death to you or other workers.
