Operation and Maintenance Manual of Aerial Work Platform
6.1 Overview
The emergency operation steps, applicable systems and controllers for the emergency during the
machine operation are specified in this chapter. The position, function and application method of the
emergency descent button or emergency stop equipment are also introduced.
Notice: all personnel responsible for operating or contacting the equipment shall review the complete
operation manual (including this chapter) before the machine operation and at the regular interval.
Emergency stop switch
There are two red emergency stop switches on the machine, which are the large buttons. One is located
on the control handle of working table, while the other one is located on the ground control box. Once
these emergency stop switches are pressed, the equipment will stop running immediately.
△
! Warning
Check the equipment every day. Ensure that the emergency stop switches are correctly
positioned and the instructions and marks of ground controller are put in place and are clear.
Position of ground controller
The ground controller panel is located at the left side of machine. With this panel, the platform control
handle can be operated and further the work platform can be lifted and lowered from the ground.
Position the power supply selector switch on the “ground” position and operate the lifting and lowering
switch to carry out the lifting and lowering operation.
Emergency descent
The manual lowering valve is applicable when the power is completely lost. The working table can be
lowered under the gravity. The manual lowering handle is located at the right side of machine, over the
right front wheel. The handle is connected to the manual lowering valve of the lifting hydraulic cylinder
via a cable. The valve core can be opened by pressing the manual lowering handle to lower the working
table.
6.2 Emergency operation
Application of ground controller
Notice: please understand how the ground controller is used in the emergency.
The ground operator must be very familiar with the operation characteristics and functions of ground
controller. The training shall cover the equipment operation. Please read and understand the contents of
this chapter and operate the controller in the stimulated emergency.
Failure to control equipment by operator
1) The equipment can be controlled via a ground controller with the assist of other staff and
equipment (crane, hoisting device and etc.) only when this operation is the must for eliminating the
hazard or emergency.
2) Other qualified operators on the working table are allowed to use the working table controller. If the
controller fails, do not continue this operation.
3) If the equipment controller fails or breaks down in the normal operation, the staff can be evacuated
and the equipment movement can be stabilized with a crane, forklift or other devices.
Stuck working table top
If the working table is stuck or blocked by a high structure or equipment, stop operating the equipment
via the working table or ground operation equipment and transfer the operator and all staff to the safe
position. In such case, the working table can be released with the assist of necessary equipment and
staff. Do not operate the controller in such a way that one or more wheels get off the ground.
Lifting of tipped-over equipment
Please place the forklift with sufficient lifting capacity and the equipment with the same capacity on the
lifting side below the chassis. When the forklift or the equipment is used for lowering the working table
chassis, please slightly lift the working table with a crane or other appropriate equipment, for fear of
tipping-over.
