Operation Instruction
5.1 Description
This machine is a self-propelled hydraulic lift equipped with a work platform on the end of an
elevating, articulating and rotating boom. Vibrations emitted by these machines are not hazardous
to an operator in the work platform. The machine can be used to position personnel with their tools
and supplies at position above ground level and can be used to reach work areas located above
and over machinery or equipment.
A full and detailed implementation of EN ISO 13849-1/2 is correctly applied on our MEWP design.
SISTEMA, a software tool for PL Calculation Tool, is also used to perform some relatively
straightforward calculations on subsystem to determine the overall PL of the system. Reliability
data, diagnostic coverage [DC], the system architecture [Category], common cause failure and,
where relevant, requirements for software are used to assess the PL to comply with PLr of
SRP/CS in Clause 5.11 of EN 280.
The primary operator control station is in the platform. From this control station, the operator can
drive and steer the machine in both forward and reverse directions. The operator can raise or
lower the boom or swing the boom to the left or right. Standard boom swing is 360 degree
continuous left and right of the stowed position. The machine has a Ground Control Station which
will override the Platform Control Station. Ground Controls operate boom lift and swing, and are to
be used in an emergency to lower the platform to the ground should the operator in the platform be
unable to do so. The Ground Control is also to be used in Pre-Start Inspection.
Instruction and hazard warnings are posted adjacent to both operator control stations and at other
places on the machine. It is extremely important that operators know what instructions and
warnings are placed on the machine, and review these periodically so that they are fresh in their
minds.
There are efficient and safe operation in accordance with warnings on the machine, in the
Operation & Maintenance Manual, and all jobsite and government rules and regulations. As with
any type of machinery, the operator is very important to efficient and safe operation. It is absolutely
necessary that the machine be regularly maintained in accordance with this manual and the
machine Service and Maintenance manual, and that any evidence of lack of maintenance,
malfunction, excessive wear, damage or modification to the machine be reported immediately to
the machine owner or the jobsite supervisor or safety manager and that the machine be taken out
of service until all discrepancies are corrected.
The machine is not intended to be used to lift material other than supplies which personnel in the
platform require to do their job. Supplies or tools which extend outside the platform are prohibited.
It must not be used as a forklift, crane, and support for overhead structure, or to push or pull
another object.
