3.1 Description
The APH 5020/5030/6020/6530/100-20 are reversible vibrating
plates operating on the basis of the twin-shaft resp. three-shaft
vibration system principle. The Engine drives the exciter on the
baseplate via hydraulic components.
The exciter produces the vibration required for compaction owing
to the incorporated out-of-balance weights.
The machine is guided at the tow-bar grip. It is operated with the
operating controls on the tow-bar.
The APH 5020/5030/6020/6530/100-20 are suitable for all heavy
compaction work in the fileds of civil Engineering and road con-
struction.
It can be used to compact all ground materials such as sand,
gravel, slag, crushed stone, asphalt and composite sett paving.
3.1.1 Overview of components
1 Baseplate with exciter
2 Engine
3 Central-point suspension
4 Tow-bar
5 Operating controls / tow-bar
3.2 Operating controls on the tow-bar
1 Engine speed control lever
0 Engine stop
I Idle (detent position)
II Full load
The Engine speed can be adjusted steplessly with the control le-
ver. At minimum Engine speed (I), the drive to the exciter is dis-
connected at the centrifugal clutch and the Engine idles.
The centrifugal clutch engages when the control lever is moved
approximately ¼ of its adjustment travel.
2 Drive lever
a Forward
b Reverse
The drive lever serves to adjust the movements in the exciter and
therefore provides a stepless control
• of the travel direction forwards (a) / backwards (b)
• of the speed
3 Emergency stop connection
1)
The emergency stop switch serves to immediately halt the ma-
chine in emergency situations.
Once the switch knob is pressed the power transmission is inter-
rupted and the machine itself stops though the Engine continues
to run.
Following the pressing of the switch during operation:
• The switch is released by withdrawing it.
• Normal operation can then be immediately resumed. (The
travel direction and speed do not need to be reselected).
