Function
The operation of a hydraulic demolition cutter is
described in a simplified version below:
Closing the hydraulic demolition cutter
The carrier driver operates the cutter valve, via a
switch on the floor or via a joystick in the carrier, for
the function
»Close«
. Line
»B«
is connected to the
rapid movement valve. The rapid movement valve
feeds oil to the hydraulic cylinders. The hydraulic
cylinders extend their piston rods in fast traverse.
The cutter jaws grip the debris. Once the debris has
generated a force in the cutter jaw, the rapid
movement valve switches to power movement. The
hydraulic cylinders extend their piston rods in power
movement. The debris is cut/broken. The piston rods
reach their end position.
Opening hydraulic demolition cutter
The carrier driver operates the cutter valve, via a
switch on the floor or via a joystick in the carrier, for
the function
»Open«
. Oil is fed to the hydraulic
cylinders via line
»A«
. The piston rods retract. The
cutter jaws open.
Hydraulically turning the hydraulic demolition
cutter
The carrier driver activates the carrier function
»Turn
gripper«
. Oil is fed to the hydraulic motor. The
hydraulic motor, located in the upper part of the
hydraulic demolition cutter, causes the lower part of
the hydraulic demolition cutter to turn (cutter casing,
cutter jaws, hydraulic cylinder).
To achieve endless turning of the lower part of the
hydraulic demolition cutter, there is a rotary
transmission between the upper part and cutter
casing. The oil flows for the functions
»Open«
and
»Close«
are transmitted through the rotary
transmission.
Signs / labels
WARNING Missing warnings
The name plate and the labels on the hydraulic
attachment contain important information about the
hydraulic attachment and for personal safety. A
missing warning can lead to overlooking or
misinterpretation of possible risks and cause personal
hazards. The signs and labels must always be clearly
legible.
►
Immediately replace any defective name plates
and labels.
