Operation and Maintenance Manual of Aerial Work Platform
5.1 Basic operation
The following items will be discussed below:
For platform controller (PCU), see Fig.2 and Fig.3.
For chassis controller (ECU), see Fig.4.
Main power supply and safety
1) The key switch controls the power supply of the machine, for which three operating modes are
available. When the key switch is set in the left position, the platform operation mode will be enabled;
when the key switch is set in the right position, the chassis operation mode will be enabled; when the
key switch is set in the middle position, the power off mode will be enabled.
Note: The key can be pluged or removed only when it is set in the middile position (some products is
optionally equipped with the keys which can be pluged or removed at the three positions).
2) An emergency stop switch is installed on the chassis and the platform controller, respectively. The
two switches are serially connected. The normal work can be done when the two switches are
pulled out. The power supply will be cut off once any emergency stop switch on the chassis or the
platform is pressed. The safety function is based on a complete loop which can be disconnected
once any emergency stop switch is pressed.
3) The functions of running, turning, lifting or lowering can be initialized only when the enable switch
on the handle is pressed.
Lifting and lifting security
1) The inclination switch on the chassis is used for indicating whether the chassis is horizontal.
2) In case the hollow protector is installed, the platform can be lifted to the height above the preset
one only when the hollow protector is initialized.
3) The load shall not exceed the rated one of this machine model.
4) The platform can be lifted or lowered from two positions, the chassis or the platform. The operation
position can be chosen via the key switch.
The platform can be only lifted or lowered via the toggle switch on the chassis.
The platform operator is allowed to choose the lifting mode on the platform. The up and down direction
and the speed can be controlled by moving the handle. The platform can be lifted by moving the handle
forward and lowered by moving it backward.
5) If the weight sensing set is available on the machine and the platform is overloaded, the main
controller (ECU) of the platform will sound, alarm and disable the operation.
6) One mode that the platform is suspended during the lowering process is available, for safe
lowering after the suspension. This is the mode of machine lowering delay setting.
7) The failure of lifting or lowering valve can be displayed via an error code on LED of PCU and ECU.
Traveling and traveling security
1) The traveling can be controlled only via the handle of PCU. In such case, the key switch must be in
the position of the platform.
2) If it is intended to move the machine, be sure to choose the traveling mode and press the enable
switch on the handle.
①
The traveling direction and speed can be controlled by moving the handle forward and backward.
②
The “high speed” or “low speed” mode can be selected only when the platform is folded. However,
when the platform is lifted and the hollow protector is lowered, the machine can only work in the
“acceleration after lifting” mode.
③
If the platform is overloaded, the lifting action is not allowed.
④
If the internal part of motor controller is overheated, the platform will be slowed down.
